The infinite space is as fascinating as scary. I mean the number of things astronomers know about space is nothing compared to what we know. How many other Milky Way’s are there? What makes black holes so scary? There might be a star exploding as you read this, but we are so unaware of it. Do you know silence feels like? Outer space is completely silent. There are screaming stars, strange nebulas, neighbouring Andromeda galaxy that will collide with the Milky Way one day, massive stars, and scientists have speculated a parallel universe some billion light years away.
If these facts have kept you hooked on, here are some to give you the chills about space.
Mass of the sun takes up 99 percent of the Solar System. And when the sun dies, it will become a red giant and will envelop the Earth and all other planets. But this will happen in another 5 billion years or so.
Light travels quite fast right? But there are parts of the universe from where the light has not reached us yet. It means that light from a few galaxies that were formed in the Big Bang has not reached Earth yet. Spooky, right?
Heard of black hole? Well, there’s this one particular black hole that is speeding through space at five million miles per hour. Like black holes weren’t scary enough. Now they got speed too?
Black hole erupts onto oneself until it evaporates. The gravity is so strong near the black hole that even light can’t escape it.
Voyager 1 spacecraft that was sent in 1977 on a mission to Jupiter is now on a second mission out of Milky Way. It will outlive the Earth that will be vaporised within a few billion years while the Voyager will keep living on.
The longest solving mystery to physicists and astronomers is Dark Matter. The gravity of the entire universe cannot be attested only to the planets, comets, stars etc. Scientists say the unobservable gravity is present – we just don’t know about it.
According to Quantum mechanics, it’s very possible for the entire universe to spontaneously disappear forever. This theory is known as vacuum decay which spells out that a random quantum fluctuation can create a potential energy of true vacuum and delete everything as they expand at the speed of light.
