What if, you are transported through a black hole to a time may be in future where you can see cars flying or to a time when the first film was made.
Well that sounds like a fiction only,but what if you are told nothing is impossible!
Now let us understand- what is a Black hole in our universe ?
Black holes are invisible things in sky. They can only be measured & seen through special instruments that scientists have designed.
As per the studies of NASA, black hole is that part of our universe that have intense gravity that pulls up the dying stars & do not let light escape through it.
Scientists researched that these black holes were formed when the galaxy was formed due to massive explosion of supernova star. Supernova star was nothing but a giant start that is exploded into the universe.
Now, we can answer our question- Can a black hole teleport us to different part of universe or to a different time zone?
Here, you have to unlearn a few things and remember the Newton's Law of attraction due to gravity.
It is all fine as long as the gravity strength is not large. So imagine, how do one treat object in or around a massive black hole with huge gravity?
Well, the Einstein's theory of Relativity (GR) comes into play. According to this theory, imagine the entire universe is sitting on a rubber sheet and as you walk around it, you move in both space and time. But when you put something massive, it warps the rubber sheet. And when there is enough of a warp, other objects roll towards the warp and find themselves orbiting around the warp.
This wrap gets deeper as the mass increases & thus increasing mass causes a never ending pit.
With such distortions there are possibilities of exotic outcomes. There will be a huge mesh of time & space.
So if, you imagine yourself in a universe where the black hole is spinning & falling into a never ending pit, there can be possibilities to fall back in time only.
Also, while falling into the never ending pit can result you to come into a different universe like a parallel one.
Thus, according to science there are all possibilities to travel to a different universe or travel in past through a black hole.
