what if Earth was half land and half water
imagine earth with an even 50 50 split between continents and oceans our planet covered half by land and half by water how would this change the planet as you know it what new kinds of vacations could this make possible for you and what does the color of your pee have to do with this this is what if and here's what would happen if the earth was half land and half water when it comes to making life possible on a planet water is an absolute have that's why we look for alien life on worlds where liquid water could exist when it comes to our own planet 71 of its surface is covered by water most of that is in our five oceans together they form one global ocean now if you replaced nearly a quarter of our ocean water with land how soon would earth turn into just another lifeless rock in space thanks to global warming earth's sea levels are currently rising but if you wanted to balance the planet's land to water ratio you'd see the sea levels absolutely plummet and not just a few meters but around three kilometers earth would look very different the regions around both the north and south poles would be completely dried out and every continent on the planet would expand and not just a little either all this newly emerged territory around the world would be roughly equal to the current surface areas of asia europe africa and north america combined that would be an enormous amount of unused space everything extending off the old coasts would be relatively flat but some of the areas that used to be deep ocean would reveal vast corridors and steep crevasses as you explored this new land you'd discover that the one global ocean would be no more all of the oceans would be separated from each other and all of the continents would be one connected landmass and this would be good news for evolution early humans didn't have any ships or planes we spread across the globe simply by walking venturing away from africa some seventy thousand to one hundred thousand years ago we found our way to europe and asia eventually we were able to cross a land bridge connecting asia to the americas possibly as far back as 20 000 years ago with the 50 50 split in place you'd now be able to cover even more ground finally you could take that around the world trip you've always dreamed of all on your own two feet but this shifting balance of water and land wouldn't be all fun and games with so much less water covering the surface our ocean currents would be disrupted and this would seriously destabilize the climate currents distribute the heat that's absorbed by the oceans around the globe disrupting them would mean even colder temperatures around the north and south poles while the already hot equatorial regions would get even hotter climate change would speed up too all because oceans wouldn't be able to absorb so much carbon dioxide from the air that excess carbon dioxide would blanket the planet and raise temperatures rain levels would also drop off and this would create dangerous droughts as well as new deserts in many inland areas so while there may be an abundance of new land available large stretches of earth could become uninhabitable plants animals and humans would all need to adapt to being less dependent on water or at least start using it more efficiently water scarcity could result in animals evolving to be smaller with more making the jump to a strictly carnivorous diet and sadly the abundance of life that today's oceans support would struggle to survive and maybe the most surprising consequence that you'd need to get used to is that your pee would likely change forever usually urine is made up of more than 90 water but with less water in your daily life yours would become much darker and start to smell like ammonia i mean things could be worse you could drain the oceans of every drop of water they have but that's a story for another what if [Music]

BIG CRUNCH THEORY: THE END OF OUR UNIVERSE
The Big Crunch Theory has its roots in Einstein's theory of general relativity. Everything in life follows an ebb and flow, with one event leading to the opposite. The Big Crunch is when the universe will reach its largest size and begin to collapse in on itself. Ultimately, it will form a massive black hole containing all matter. Because of the conditions present at the singularity of size, everything will be squashed down to a minuscule size. This is why it's called the Big Crunch. So, it appears that the Big Crunch is possible and even probable, but there's a problem with those who dedicate their careers to exploring this question - we don't yet understand everything in the universe. A couple of unknowns could affect our ultimate fate, and one of them is its outward expansion. The more dense the universe is, the more gravitational forces take place. This on its own would mean that everything would eventually gravitate towards each other and the final Big Crunch becomes an inevitability. In space, there is no friction. However, gravity from the Big Bang counteracts the initial outward momentum. All matter returns to its origin. Observations of the universe show that things are not behaving as expected. The outer reaches are expanding faster than the closer ones. Galaxies are moving further apart. Scientists call this unknown entity dark energy. There are two potential outcomes: continued expansion or a Big Crunch. The amount of dark energy determines the outcome. If there is enough, everything will continue to expand. If not, gravity will bring everything back together. Some believe dark energy signals the beginning of the Big Crunch. However, a 2015 report suggests that the current expansion is the last gasp. Within billions of years, contraction will begin so. How might the Big Crunch come about? If we assume that there isn't enough dark energy and that the Big Crunch happens, 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 will be a slow process that will gradually pick up speed as galaxies get closer to one another and the forces of gravity have more of an effect in about a hundred billion years as things reach. This will result in stars exploding and vaporizing, and all objects will be broken down into their constituent atoms, which will begin to break apart in the final stages as all matter from the universe compacts into a small space. Some predictions suggest that space-time will become so warped that it will shatter into droplets, rendering all concepts of time, distance, and direction 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 processes taking place in the universe it's impossible to know for sure how everything will end one of the scenarios is the Big Crunch which will see every piece of matter returning to where it originated in and all that will remain to be an unimaginably large black hole. It could potentially see the birth of a new universe, but it's also possible that this has all happened before and we're living in just another in a long line of cyclical expansions and contractions. Only those of you who plan to live for billions of years need to be concerned about this. It's essential to emphasize that our understanding of the universe's fate is subject to ongoing research and observation. New data and discoveries might lead to revisions in cosmological theories, and other possibilities may emerge as more is learned about dark energy, dark matter, and the fundamental nature of the cosmos. Always refer to the latest scientific sources for the most up-to-date information on cosmology and the fate of the universe.

VITAMIN D
Getting sufficient vitamin D through diet or enhancements may be useful in overseeing psoriasis, an immune system sickness that causes irritated, flaky patches on the skin, scientists say that the case comes from another review introduced Tuesday at Sustenance 2023, the yearly gathering of the American Culture for Nourishment. However the discoveries are fundamental and haven't yet been distributed in a companion surveyed diary, specialists say that increasing your admission of vitamin D could be a somewhat okay approach to lessening psoriasis severity.
