Question

time travel travelling is possible ? explain ways to time travel​

Answer 1

according to Einstein and theory of relativity time travel is possible.

______________________________

during research on time travel scientists tried to research on travelling in past and they got success when they got discovered worm holes

first we will discuss about what is wormhole.

actually there are 10 dimensions in our universe but we can see upto 3dimensions only.

lets take an example

suppose you are moving in. a car

if you are travelling straight then thats 1st dimension.

if you move left and right too thats 2nd dimension

if there is a mountain and you go through mountain then Thats 3rd dimension.

means.

0D means a point

1D means having length

2D means having length and breadth too

and.

3D means having length, breadth and height.

but there is also type of length which we can't see thats the length of time.

thats called four dimensional space time.

now come to the topic.

as we know nothing is totally smooth in this universe means all the things are rough means there will be hole in everything.

and we know time is also a physical quantity .

means time have also some holes

that holes called wormhole.

and if any object travel through wormhole they can go in past.

but they are too small even then quark and bosons.

and if any one will do time travel to past then there will be the situation called paradox

(virodhabas)

means

suppose you travelled in past and

you killed yourself.

but you died in past so how can you be in present.

and who killed you because you died in past.

thats called paradox (virodhabas) actually this is a hindi word.

so no one can travel in past.

but we can travel in. future.

According to theory of general relativity

varries because of mass.

means when object is near a very heavy object or things then time slows down there but that need very large amount of. mass.

means thats should be a big planet but it can't slows down time more because it is very lighter for doing long time travel .

but there is one thing in universe which is heaviest thing in this universe thats a big black hole.

if any spacecraft revolve around a big black hole it can travel time.

we can also find how much we travel time by a formula

but doing this we cant travel more in past.

and this is dangerous also as of spacecraft falls in black hole it will destroyed

but there is also another method.

according to. theory of relativity

nothing can travel higher than the speed of light.

and any object will travel at that speed then the physical law will stop them.

means any object. can travel 99.99% of speed of light but not 100%.

so we can use this

if any object will travel close to speed of light then that object will travel time.
