Hey There Hivers!!
Today i am going to talk about the Time Travelling to Past. It is going to be continuing part of my previous post if u wanna know about time travelling to Future You check it out here : @fakhir12/is-time-travel-really-possible
So Let's Continue.
Well You can't travel to past by travelling at the speed of light. Travelling to past is more hard than travelling to future because of " The Grandfather Paradox". It states that :
What If somehow you traveled to past and You killed your own Grandfather. So how will you exist in this time, Meaning if your grandfather is dead your father won't be born and so how did you born? and if you never born then who killed him?
So it's a really confusing paradox and that's why many people believe that travelling to past is not possible. But according to Stephen Hawking that it is possible and the way is called "The Wormhole". Which was first discovered by "Albert Einstein" and because of that Wormhole's other name is "Einstein Rosen Bridge".
Wormhole is like a tunnel which connects two parts and time of this Universe But it is a very non-theoretical thing meaning that scientist has claimed that wormhole exists but no one has ever seen it. So yeah it can be said that the chances of it's existence are low and it is really a mystery and like other unexplainable things, only theories about wormholes exist it is only mathematically proved not practically.
The most interesting way of time travelling is through a Time Machine. But in reality the Time Machine is really just a Science-Fiction
To run the Time Machine a special type of fuel would be necessary which is known as "Negative Energy". And even Negative Energy is a theoretical concept, which just like other mysterical things, is only mathematically proved. And no one has the special formula to make a Time Machine. But I hope that in future we will be able to make Time Machine.
Well it was all the knowledge I had about Time Travelling and everything You needed to know about hope so you guys like my post!
I got an interesting question for you all if it was somehow possible to make a Time Machine where would you wanna go and why?
