5 Mysteries Of Space That Science Can't Explain

#5: The Missing Matter

The universe is filled with 95% dark matter and dark energy which we know extremely little about, but the remaining 5% is made up of atoms and ions the same materials that make up our stars, planets, dogs, and even ourselves. This material is called baryonic matter and if the big bang theory is correct there should be twice as many as we can detect. So where is it?

#4: Super Charged Space Rays

at the south pole, there is a scientific outpost called the IceCube neutrino observatory. The function of the IceCube neutrino observatory is to capture signs of the illusive sub-atomic particles known as neutrinos, but shortly after its construction, it discovered something else that is just as mysterious. The problem with neutrino observatories is that they are constantly being bombarded with a bunch of different signals. Most of the signals are considered background noise, but one set of signals was way too mysterious to ignore. Scientists figured out this signal was an intensity of cosmic rays hitting the southern hemisphere. Scientists don't know what caused the cosmic rays or why they are making such a high signal while also being so far away. What do you think caused it?

#3: The Mysterious Void

The Boötes void is 250-330 million light-years across with extremely little amount of matter. This area is located 700 million light-years from Earth and is near the Bootes constellation. There is barely anything observable in this patch of space making it a pitch-black patch of space, but what in the universe could have made this void? What do you think happened?

#2: The Space Roar

In 2006 NASA sent a balloon to the top of Earth's atmosphere, the purpose of the balloon was to detect radio signals and heat traces from galaxies and stars light-years away, signals they could be sure wouldn't be distorted by those on Earth. Somehow they managed to get something and nothing at the same time. NASA's devices received a radio signal 6 times stronger than expected. With a radio signal that strong this thing would have to be massive. NASA has stated that it was not from a supermassive black hole, star vibrations, or something happening in our galaxy.

#1: The Unidentifiable Probe

In November 1991, astronomer James Scotty was searching the sky for asteroids. When he saw something flying through the solar system that didn't look like an asteroid at all. James Scotty tracked and investigated the object, and figured out that it was only 10 meters across and gave off unusual amounts of light, and was rotating in a most peculiar fashion and was rotating around the sun unusually similar to the Earth. This object was named 1991 VG, further investigation of 1991 VG made it clear that this was not the first time it had gone around Earth, and 1991 would not be the first or the last time 1991 VG would go around Earth. To this day nobody knows what 1991 VG is or how it got here. What do you think it is?

Bonus: Radio signals

Throughout 2018 and 2019 the Canadian hydrogen intensity mapping experiment detected a pattern of radio signals that occurred every 16 days. This was just one of the radio signals detected by the researchers. These sources were traced to different parts of space, including a massive spiral galaxy about 500 million light-years away from Earth. The signals likely stem from what is called a magnetar which is a neuron star with an incredibly powerful magnetic field, but that is just a hypothesis to this day we have no idea what is behind them.
