How Will Our Universe End? Big Crunch Theory
we've all heard about the big bang and I am really sad that the series has ended well here of course I'm talking about the Big Bang that actually started everything again most people have heard of that but what do you know about the Big Crunch and now I'm not talking about some random candy bar while most scientists believe that our universe began with a massive burst of energy opinions remain divided about how everything will one day come to an end there's a range of theories such as the big fries and the big rip but the one that's considered to be the most likely scenario is the Big Crunch so what is the Big Crunch but the Big Crunch Theory has its roots in Einstein's theory of general relativity everything in life follows an ebb and flow when one event occurs the reverse is likely to occur after hitting the extreme if the Big Bang causes the expansion of the universe then eventually the opposite will become true once the universe has reached its largest size and as determined by the amount of energy that's present it will begin to be collapsed in on itself and in the end form a massive black hole that contains all matter due to the conditions that are present in the singularity of the size everything will be squashed down to a miniscule size which is why it's called the Big Crunch so probably not great news for all those of you who are a class or for bacon and tend to live billions of years well here's the good news while the math suggests that the Big Crunch is possible and even probable there's a problem for those who dedicate their careers to understanding questions like this we don't yet fully comprehending everything in a universe and there are a couple of unknowns that will affect our ultimate fate first the universe's expansion appears to be the interplay of two factors density and outward momentum density has a direct correlation to the amount of gravity that is present so the denser the universe is the more gravitational forces that take place this on its own would mean that everything will eventually gravitate towards everything else and the final Big Crunch becomes an inevitability although there's no friction in space the effect of gravity would be more than enough to counteract the initial outward momentum caused by the Big Bang and all matter what essentially returned to where come from the problem with this though is that observations of the universe have shown that things aren't behaving as simply as we would expect the outer reaches appear to be expanding at a faster rate than those closer to us and galaxies are actually moving further apart from each other scientists don't know why this is happening but they have given a name to this unknown entity dark energy this extra element in the expansion of the universe means that there are two potential outcomes it will either continue to expand forever and objects will be so far apart from each other that everything will freeze were we could still faced a Big Crunch the determining factor is how much dark energy are actually there if there is enough which some scientists believe could be the case then everything will continue to expand if there isn't enough though then the forces of gravity will once more eventually over comment and bring everything back together again some believe the seeming prevalence of dark energy could well signal the beginning of the Big Crunch however in a report released in 2015 it was suggested that the current increased rates of expansion is the last gasp of the expanding universe and that within tens of billions of years the contraction will begin so how would the Big Crunch happen if we assume that there isn't enough dark energy and that the Big Crunch does take place then it won't be as spectacular as the Big Bang was the universe will begin to contract evenly because matter is more or less distributed consistently it would be a slow process for what begin to gradually pick up in speed as galaxies got closer to one another and the forces of gravity have more of an effect in about a hundred billion years from now as things reach and climax temperatures would significantly increase in this will result in stars exploding and in vaporizing and all objects will be broken down into their constituent atoms which themselves will begin to break apart in the final stages as all matter from the universe compacts into a small space things will become extremely chaotic so much so that some predictions suggest as space-time will become so warped that it would shatter into droplets meaning all concepts of time distance and a direction would become meaningless of course no living organism would have been able to survive to this point in we would have all been doomed a long time before this so with our lack of full understanding of the process taking place in the universe it's impossible to know for sure how everything will end one of the scenario is the Big Crunch which will see every piece of the matter returning to where it originated in and all that will remain to be an unimaginably large black hole what happens at that point really is anyone's guess and it could potentially see the birth of a new universe it's also possible that this has all happened a number of times already and we're alive in just another in a long line of cyclical expansions and contractions again only those of you who's planning to be alive for billions of years will really have to worry about this.

Scientists discover first-ever Bose-Einstein state in magnons reshaping physics. AI-Generated.
Scientists discover first-ever Bose-Einstein state in magnons reshaping physics The recent discovery of the first-ever Bose-Einstein condensate (BEC) state in magnons marks a significant breakthrough in condensed matter physics. This discovery reshapes our understanding of quantum mechanics, magnetism, and potential applications in future technologies such as quantum computing and spintronics. Bose-Einstein condensates, first predicted by Albert Einstein and Satyendra Nath Bose in the 1920s, are a unique state of matter where particles known as bosons cool to temperatures near absolute zero and behave as a single quantum entity. Until now, BECs have been observed in atoms and other quasiparticles, but the confirmation of this phenomenon in magnons opens new possibilities in fundamental and applied physics. Magnons are the collective excitations of electron spins in a magnet, acting as quasiparticles that carry angular momentum and energy. These excitations emerge due to the quantum mechanical interactions between electrons in a solid material. Magnons play a crucial role in magnetic properties and have been the subject of extensive research in spintronics, a field that explores the use of electron spin for information processing. The formation of a Bose-Einstein condensate in magnons implies that, under certain conditions, these quasiparticles can synchronize their quantum states, forming a macroscopic wave function similar to what occurs in superfluidity and superconductivity.

The moon's volcano🌋
the moon's volcanoes are not dormant and they can erupt any minute for years we lived knowing nothing about it but now it's officially proven thanks to China's Chong 5 Mission shocking Discovery the lunar soil samples it brought back to Earth contained something absolutely unexpected hinting that volcanic eruptions may have occurred on the moon as recently as 123 million years ago geologically that's practically yesterday but the big question is are we safe down here on Earth we've long known that the moon was once volcanically active due to the dark regions lunar maria on its surface these Maria the dark plains that give the moon its characteristic markings are ancient lava flows that date back to around 3 to 3.8 billion years ago until recently scientists thought that those ancient flows marked the end of the moon's volcanic activity but the Chong 5 Mission brought back lunar soil that included several microscopic glass beads and three of them in particular revealed an extraordinary story they formed around 123 million years ago from volcanic eruptions an uncertainty range is a mere 15 million years the discovery of those tiny beads is super important because of their composition and Rarity measuring between 20 to 400 microns which is smaller than a grain of sand these beads are volcanic in origin and this fact sets them apart from most other lunar glass beads which typically form due to meteor impacts impact events on the moon create Glass by melting surface rock with Incredible heat and pressure the result is Tiny glass beads scattered all over the landscape yet the volcanic beads identified in Chong 5 sample were formed by magma erupting from beneath the moon's crust and cooling it into glass as it reach the Surface by using uranium lead dating which measures the decay of uranium into lead within the beads scientists managed to pinpoint their age with striking accuracy the results suggest that the last known volcanic activity on the moon happened within the past 200 million years making it a recent event in the moon's long history this discovery also aligns with prior observations of unusual surface features known as irregular M patches those are smooth Mounds surrounded by Rocky terrain they were first spotted by NASA's lunar reconnaissance Orbiter in 2014 these patches appear much younger than other lunar features potentially formed by volcanic eruptions less than 100 million years ago before Chong 5's glass beads these irregular M patches were among the best evidence of recent volcanic activity on the moon yet without confirmation their Origins remain uncertain and now the glass beads confirm volcanic action the findings raise new questions about the moon's inner workings in particular how could it retain enough heat to sustain volcanic eruptions we thought that the Moon had cooled significantly after its formation 4.5 billion years ago which made it volcanically inactive and without tectonic activity or an atmosphere the moon should have shed its internal heat long ago yet the beads suggest the possibility of some localized heat sources within the moon's mantle scientists think that heat producing elements such as potassium and thorium might be creating small warm pockets which generate enough heat to melt rock and Trigger isolated volcanic eruptions but wait Beyond rewriting the moon's history this discovery adds an intriguing twist to ongoing studies of transient lunar phenomena these sightings often reported as ghostly glows or hazes by amateur astronomers remain unconfirmed by scientific probes some experts just dismiss them as Illusions caused by Earth atmosphere but if the moon has small pockets of volcanic or outgassing activity TLP might have a real basis gases emitted from beneath the surface could explain such mysterious glows and possibly be a hint of residual volcanic action on the moon now if volcanic activity still lingers on the moon this might have exciting implications for future lunar missions in the coming decades astronauts might be able to use volcanic heat for generating power melting ice into water or even warming bases built into the frigid luner surface but recent geological discoveries aren't limited to Earth's natural satellite we learn more about volcanic moons beyond our solar system too the detection of a possibly volcanic exomoon orbiting exoplanet wasp 49b around 635 light years away means that volcanic activity may be a common feature among moons up until now Jupiter's moon EO held the title of the most volcanic body we know about but researchers at NASA's jet propulsion laboratory may have found a new candidate this potential exomoon came to light when scientists observed a cloud of sodium gas around the exoplanet but the thing is sodium clouds are unusual in planetary atmospheres and can suggest volcanic activity the sodium Cloud near wasp 49b had a bizarre unexpected Behavior it was moving erratically shifting size and occupying a space too large to be explained by the exoplanet's own atmosphere scientists thought the cloud could actually be generated by a volcanically active exomoon in orbit around wasp 49b volcanic moons like EO are known to release gases such as sulfur dioxide sodium and potassium which form massive clouds around their parent Planet EO for instance regularly produces vast amounts of gas that form a cloud encircling Jupiter up to 1,000 times the size of the gas giant itself if something similar occurs near wasp 49b the gas cloud could be a clue to volcanic activity on an exomoon orbiting the planet observ from the European Southern observatory's very large telescope in Chile seems to confirm this Theory the sodium Cloud around wasp 49b is positioned high above the exoplanet's atmosphere and behaves in ways that don't match the exop planet's 2.8 Earth Day orbit this could suggest that it originates from a separate body likely a volcanically active Moon additionally wasp 49b and its host star consists primarily of hydrogen and helium which makes the sodium Cloud even more unusual The observed rate of sodium release over 220,000 lb per second can be a sign of an immensely powerful volcanic Source if scientists verify the existence of this exomoon it would be the first discovery of a volcanic exomoon back in our solar system EO Remains the main space object helping us understand volcanic moons recently NASA's Juno spacecraft provided some of the closest images of eio since the Galileo Mission over 25 years ago io's intense volcanic activity is caused by tidal heating the result of the gravitational pull of Jupiter and nearby moons like Europa this tavore generates immense friction within eio producing heat that fuels continuous volcanic eruptions one of Juno's most exciting recent findings was a new volcano that appeared just south of io's equator Juno's images show a large complex volcanic region approximately 111 by 111 mil in size the craziest thing it wasn't there when Galileo imaged the same spot in 1997 this new volcano formed near the previously known volcano kind of he researchers say that this new volcanic structure is a great change that highlights the dynamic nature of EO surface eo's equatorial region is home to most of its volcanoes because of the concentrated tidal heating it experiences the most powerful eruptions emit sulfurous gases and produce bright lava flows they cover the moon in colorful sulfur Rich deposits Juno Cam's image taken from about 1,000 570 M away shows EO dramatically lit by sunlight reflected off Jupiter and you can see a stunning view of its constantly changing volcanic surface despite these detailed observations there are still many mysteries about eo's volcanism scientists are particularly curious about how tidal heating affects eo's interior and whether it has a subsurface magma ocean plus research try to understand what triggers different types of eruptions for example plumes versus lava flows and how volcanic gases shape eo's surface and thin atmosphere the study of volcanic moons from EO to the possible exomoon near wasp 49b sheds light on how tidal forces create volcanic activity in different moons in icy moons like Europa tidal heating sustains liquid oceans beneath the surface creating potential habitats for life but for EO without an ocean the same forces instead generate powerful volcanic activity plus if volcanic exomoons do exist like the one possibly orbiting wasp 49b we might soon discover more volcanic bodies across the Galaxy.

Dark matter start
scientists have found an invisible star at the Milky Way Center a star that helped our galaxy be born 26,000 light years away in the galactic center a massive invisible object started spreading everywhere and you don't even know that you're breathing it right now it all started in the 7s when an astronomer named Vera ruin was studying the Andromeda galaxy she decided to check whether stars move in a predictable way now let's say you're spinning a ball on a string around yourself the closer the ball is to you the faster it moves in a tight Circle but if you let the string out longer the ball moves more slowly in a bigger Loop that's how gravity works and the same goes for planets the closer ones like Mercury Zoom around quickly completing their orbits in months the far ones like Neptune and Saturn take their time decades to make one rotation the Stars the El should orbit the centers of their galaxies the same way the closer ones move fast the farther ones are slower right but when Vera measured the speeds she saw something impossible they weren't slowing down the farway stars were moving just as fast as the ones near the center by all Logic the galaxies should have torn themselves apart but they didn't and that meant something was holding them together something undetectable some massive invisible object in the galactic center warping reality without ever revealing itself so she checked over and over with different galaxies this wasn't a flute it was happening everywhere Reuben had accidentallyuncovered proof that galaxies were drowning in something far heavier than all the stars planets and gas in our entire universe combined it was holding us with ghostly hands astronomers called it dark matter because it doesn't glow doesn't reflect light doesn't seem to interact with anything at all it's just there but all the calculations show us that it exists and not merely exists but makes up 85% of all the mass in the universe we know that it's sculpted galaxies without it the world as we know it wouldn't exist and yet just like with an invisible star scientists found at the Milky Way Center the only way to detect it was through gravity so how do you find something that refuses to be found recently scientists discovered there might be an invisible star at the Milky Way Center and this fascinating Discovery might finally help us understand what Dark Matter looks like they began looking for Dark Matters fingerprints any signs of its presence anywhere they studied how galaxies moved and smashed particles together in giant machines hoping to create tiny bits of dark matter in the lab this didn't really lead to anything they didn't even know what to look for is dark matter even made of particles there was a theory that suggested that it's made of ghostly particles that barely touch anything or even weirder ones that might flicker in and out of existence in the blink of an eye there was a problem though if dark matter really worked like that then the centers of galaxies should be packed tight tons of matter would be crammed into a tiny space but but in our universe Galactic cores seem strangely soft spread out almost gentle a new Theory emerged and it was wild what if the dark matter at the heart of galaxies isn't made of heavy particles at all what if it's made of something so delicate that it behaves more like a strand of hair these hairs could be made of something incredibly light lighter than anything we've ever seen and billions of times smaller than a neutrino which is already the lightest known particle they called this idea fuzzy dark matter and it might change everything we thought we knew about the universe a team of astrophysicists wanted to test this idea so they ran a simulation creating a simple model of a galaxy with two main ingredients a whole lot of fuzzy dark matter and a little bit of gas the same kind of gas that forms the star as we can see they Press Start and just let the system evolve by itself watching how the two would interact at first everything was pure chaos but then the fuzzy Dark Matter started to gather it pulled itself together forming a massive invisible object near a galactic center the gas followed spreading throughout this ghostly Mass mixing with it and glowing faintly and then it suddenly formed something incredible dark stars not typical stars like our sun blazing with heat and light instead it it's enormous massive invisible objects a hybrid of two different kinds of matter we've never never seen anything like this before an object that would stretch across thousands of light years and yet they'd be almost weightless more like Cosmic puffy clouds than anything else scientists called them firmian bosen Stars finally this dark matter thing is starting to make sense the core of this strange invisible star would have just the right density not too dense not too loose and it looked exactly like what astronomers actually see in real galaxies if it's confirmed then it would finally explain how dark matter behaves and works and if they're right then every galaxy in the universe could be tied to one of those vast unseen Giants the Milky Way hidden star might be one of them shaping our galaxy in ways we never realized what's Wild is that this stuff wouldn't behave like normal matter it wouldn't form anything solid instead it would be more like a complex ever moving web of filaments or hairs this also means that Earth might be completely surrounded by it dark matter still follows the rules of gravity as it moves past planets and stars gravity pulls it into Focus streams so it's both hugging and passing through our planet wobbling consistently if we could see them they might look like glowing invisible threads heads everywhere and they' Pierce right through the planet stretching far into space but this is only the beginning now scientists need to refine their models make them even more detailed and compare their predictions to real galaxies but this darkar discovery in the Galaxy Center isn't our only clue luckily the universe has given us a way to look for that fingerprint gravitational lensing when light from a far away Galaxy Travels toward us it sometimes passes by another massive Galaxy on the way or other massive objects with crazy gravity instead of continuing in the straight stream light actually gets bent around the massive object because of that gravity and when it finally reaches us it creates a distorted and magnified version of the original Galaxy basically it's like looking through a piece of curved glass if dark matter is fuzzy then it should leave a strange pattern on these distorted images things should be a bit wavy and unclear scientists needed the perfect object to study this and they found one a far away Galaxy whose light was Bent by gravity creating a strange stretched out image they used super powerful radio telescopes connected them all over the world and turned them into one giant telescope as big as the Earth itself with this they could zoom in so much that they could see details of that Galaxy as Tiny as a grain of sand on the moon then they ran a huge experiment they created their own fake versions of this picture simulations with various sizes of fuzzy Dark Matter particles and at a certain point they found the perfect match this helped us calculate the exact mass of Dark Matter particles before we even detected them and the clues are leading us right to our own Galaxy it seems like densest parts of these hairs the root might be super close in the cosmic scale just tens of thousands of miles from Earth that's close enough for a space probe to reach now that scientists have found this invisible star at the Milky Way Center we just need to study it up close send a mission to one of these roots.
