Do wormholes really exist in spacetime?

In summary: It's quite the same, it's ridiculous and it obviously exists. But AFAIK it exists only on small scales and has to be countered by positive energy density in the vicinity. But as George Jones said, we don't know yet what restrictions might apply.Denisty is an abbreviation for "denormalization of density," which is a phenomenon in quantum mechanics that can lead to the appearance of negative masses and negative energies.

Do wormholes really exist in spacetime?
I mean, as a race we need to colonize the rest of the galaxy before too long otherwise the sun will extinguish our aspirations to survive, and we really can't just travel in a spaceship so we need to look at other ideas.

could "star-trek" or whatever the show is be real and wormholes or rips in the fabric of space appear so that we could go through them and end up in another part of the galaxy in minutes rather than thousands and thousands of years?

Unfortunately, there are no clear-cut answers (even in theory) upon which the whole physics community agrees.

A stable wormhole requires "exotic" matter to hold it open, and exotic matter is such that some observers measure its density to be negative.

There are some hints from quantum theory that exotic matter is theoretically possible, but not everyone agrees on how much is needed to hold a wormhole open, how much is possible, etc.

Your questions lie in an area of active research.

can u help me understand something i read involving "quantum foam"
it said that it was a miniscule substance which covered everything and was a foam-like thing that shifted and flowed around itself, occasionally opening up breaks in the "fabric of space"

Uh how can you have negative density? Isnt that just as rediculous as negative mass?

slow down guys... where did denisty come into this at all?
 

Related to Do wormholes really exist in spacetime?

1. Do wormholes really exist in spacetime?

There is currently no concrete evidence that wormholes exist in spacetime. They are a theoretical concept predicted by Einstein's theory of general relativity, but have not been observed or confirmed.

2. How are wormholes formed?

Wormholes can potentially be formed through a process known as "wormhole creation" in which a highly advanced civilization could manipulate spacetime to create a wormhole.

3. Can we travel through a wormhole?

Theoretically, it is possible to travel through a wormhole if one were to exist. However, the intense gravitational forces and other complexities involved make it currently impossible for humans to travel through a wormhole.

4. Are there any real-life examples of wormholes?

No, there are no confirmed examples of wormholes in our universe. However, there have been some observations of objects that exhibit similar properties to what we would expect from a wormhole, but further research is needed to confirm their existence.

5. What would happen if we were to enter a wormhole?

The effects of entering a wormhole are largely unknown and purely theoretical at this point. Some theories suggest that it could potentially lead to time travel or travel to different universes, while others believe it could have devastating effects on the human body due to the intense forces involved.
