Can wormholes exist in a flat universe?

So, a wormhole, like a black hole, can exist in a flat universe. The spacetime manifold has to support curvature in order for a wormhole to exist, but a wormhole can exist between point that are otherwise largely flat.

Would a wormhole be a sphere?

The wormhole will be a sphere connecting the two parts of the space. The boundary of a wormhole can be of any shape. It doesn’t have to be a sphere, a circle, or any other symmetric shape.

What is the fate of Universe if space is flat?

If space has no curvature (i.e, it is flat), there is exactly enough mass to cause the expansion to stop, but only after an infinite amount of time. Thus, the universe has no bounds and will also expand forever, but with the rate of expansion gradually approaching zero after an infinite amount of time.

Have we found a wormhole yet?

Wormholes are still in the realm of the imagination. But some scientists think we will soon be able to find them, too. Over the past few months, several new studies have suggested intriguing ways forward. Some wormholes may be “traversable”, meaning humans may be able to travel through them.

Can we open a wormhole?

Not when you can pop into the nearest wormhole opening, take a short stroll, and end up in some exotic far-flung corner of the universe. There’s a small technical difficulty, though: Wormholes, which are bends in space-time so extreme that a shortcut tunnel forms, are catastrophically unstable.

Are we in a flat universe?

The exact shape is still a matter of debate in physical cosmology, but experimental data from various independent sources (WMAP, BOOMERanG, and Planck for example) confirm that the universe is flat with only a 0.4\% margin of error.

Can a wormhole exist in a flat universe?

A wormhole can ONLY exist in a flat universe because the wormhole, and the flat universe, are descriptions of the outer state of their existence and NOT what caused their existence in the first place.

How do you use a wormhole to travel in time?

Wormholes connect two points in spacetime, which means that they would in principle allow travel in time, as well as in space. In 1988, Morris, Thorne and Yurtsever worked out how to convert a wormhole traversing space into one traversing time by accelerating one of its two mouths.

Why is the universe flat?

The Universe is NOT flat and wormholes CANNOT exist outside of the condition that caused them to exist. It is not only the collapse of an extremely massive object that can create this condition… a very high amount of energy in a small place and time can also cause this.

Could a wormhole held open by a negative mass cosmic string?

It has also been proposed that, if a tiny wormhole held open by a negative mass cosmic string had appeared around the time of the Big Bang, it could have been inflated to macroscopic size by cosmic inflation.
