Wormholes were thought to exist via black holes, like the movie The Black Hole. That idea was taken back this year so now black holes are just thought to be strong gravitational objects with no special properties.
Time travel was never possible. The closest thing to seeing the past is by looking at like that was projected by objects. The light from our sun is around 9 minutes old.

In physics, a wormhole (also known as Abbreviated Space) is a hypothetical topological feature of spacetime that is essentially a "shortcut" or "abbreviation" through space and time. A wormhole has at least two mouths which are connected to a single throat. If the wormhole is traversable, matter can 'travel' from one mouth to the other by passing through the throat.
The term wormhole was introduced by the American theoretical physicist John Wheeler in 1957:
This analysis forces one to consider situations..where there is a net flux of lines of force through what topologists would call a handle of the multiply-connected space and what physicists might perhaps be excused for more vividly terming a ‘wormhole’.
— John Wheeler in Annals of Physics
The name "wormhole" comes from an analogy used to explain the phenomenon. If a worm is travelling over the skin of an apple, then the worm could take a shortcut to the opposite side of the apple's skin by burrowing through its center, rather than travelling the entire distance around, just as a wormhole traveller could take a shortcut to the opposite side of the universe through a hole in higher-dimensional space.

Worm holes are science-fiction artifacts that are associated with black holes.
Black holes are theoretical entities that do not exist.
If time travel were possible every second of time would be swamped with time travelers from the past and the future.
I would be one of them!!

wormholes are breaches in the fabric of the universed cause by extreme gravitational warping- so says steven hawkings~!
