Question

why time travel is not possible by wormhole ?​

Answer 1

Answer:There’s only one problem from anyone wishing to get a glimpse of the future – getting back. It would mean travelling faster than light – and that’s not possible.

But there may be an out to be found in general relativity, Einstein’s theory of gravity that unites space and time as “spacetime”, which curves in the presence of mass. It allows for the possibility of wormholes – a kind of tunnel through spacetime connecting otherwise very distant parts of the universe.

If the “mouths” of the wormhole are moving relative to one another, then traversing the bridge between different points in space would also take a traveller to a different point in time to that in which she started.

Answer 2

Answer:

Time travel possible through wormholes but you can only go ever backward

Time travel through a wormhole is technically feasible under the rules of theoretical physics

the only catch is that we can only go ever backward

In blog post for forbes,astrophysicist

Ethan Siegel has explained just how within the realms of Einstein's general relativity a person could travel through wormhole and go back in time

He said that we first need to consider the wormhole a portal through space created by energy fluctuation inpositive and negative direction.The different fluctuations would each create a curved space the opposes the other.If these two then connected,you would have a wormhole.If it lasted long enough,theoretically a particle could be transported through............
