There are many mysteries about the Universe. What triggered the Big Bang? Was there anything before it? Why is the human cell so incredibly complex? What happens with the human consciousness after we die? What happens with the matter absorbed by a black hole? Why is Joe Biden still President?
Jokes aside, for now! Last but not least, many scientists are wondering what exactly is dark matter and how did it form? Astrophysicists had always been baffled by the mysterious form of matter that accounts for roughly 85% of the Universe’s “stuff” and about 27% of its total mass–energy density. In other words, dark matter is much more prevalent than the normal matter that we interact with every day, hour, minute, and second.
Setting up huge vats of liquid xenon and highly sensitive detectors in the search for dark matter
According to The Guardian, scientists from subterranean labs from the USA and Italy are building some rigs for spotting subatomic collisions that will hopefully reveal the presence of dark matter. They’re using vats of liquid xenon and very sensitive detectors for spotting subatomic collisions.
The current generation of detectors is approaching the limit of its effectiveness.
Chamkaur Ghag, who is a physicist professor at the University College London, declared as quoted by The Guardian:
Dark matter accounts for around 85% of all the Universe’s mass but we have not been able to detect it so far – despite building more and more powerful detectors,
We are now getting close to the limits of our detectors and if they do not find dark matter in the next few years, we may have to accept there is something very wrong with the way we think about the universe and about gravity.
Dark matter is believed to hold galaxies together.
Most of what scientists know about gravity nowadays is due to the discoveries of Albert Einstein about 100 years ago. Proving him wrong seems like blasphemy for physics, but who knows, only time will tell for sure.
