Can you tell me the difference between a blackhole and a wormhole?

A black hole is an area where gravity is so strong that nothing can escape it, not even light. Blackholes are the remnants of supernovas.

Wormholes are theoretical, but what they are believed to be is a link from one point in space to another. It would be useful for traveling vast distances in space at a respectable speed. To sustain a wormhole, however would require astronomical amounts of energy that we can’t harness yet.

So to answer your second question, no they are not the same thing.

Black holes exist and have been seen.

A wormhole is two black holes united via a tunnel. We have no way of checking out if such things really exist, and they are for now just an imaginary possibility.

A black hole has to do with the universe, and gravity. A black hole is so strong light cant get out once it gets in. As I’m reading parrappas answer is close to mine.. I agree with him/her

A black whole can destroy The Andromeda but a wormhole can transport it.

I love that show! I’d definitely be Harper!

a black hole forms after a supernova (when a star dies) and drags all matter to a single point crushing it along the way. A worm hole is like a teleport and is supposedly where two points in space are connected through a ribbon which is when space bends and forms two opposite points that are connected through this quicker route.

Worm holes don’t require a lot of energy, they are just very unstable. For example, the laws of physics allow a needle to stand upright on its point if perfectly balanced, but you will never see that in nature.

A black hole creates a huge chasm in space time that you could fall into and never get out. If at another point in space time a chasm was also formed, and they touched, it would be possible to go in one chasm and fall out the other.

So they are somewhat related, black holes can theoretically form worm holes. I am sure the wikipedia article article on each subject is much better at explaining that I though.

Black holes are composed of matter so dense that space-time is warped so dramatically that even light is unable to escape, for the most part. Thanks to quantum statistical fluctuations matter can still escape in the form of Hawking Radiation. It is important to note that they are not holes at all, but just appear so because they do not emit light, and so appear black in all parts of the spectrum. You cannot travel into or through a black hole, you would just be spaghettified. Black holes have been observed, and are important in the dynamics of a galaxy.

Worm holes are theoretical only, and have not been observed. They are said to be areas where space-time is warped in such a way that the conventional distance between two points is drastically curved, but the straight path through the worm hole is far shorter. They are unstable, and therefore short lived.

OK guys thank you for your answers.
A few of you state that a wormhole is unstable and it is a quick point between A and B, that surely would be impractical to travel through as it could collapse whilst you pass through?

Black hole “collapsed star”
Worm Hole “Collapsed and folded space”
YW

Sorry don’t get the idea of collasped space? How can a void collapse? What is collapsing?

@Mat74UK not just impractical, impossible. Right now it’s even theoretically impossible, but it could theoretically become theoretically possible someday, which is the first step to eventually becoming practical too.

First of all, the spaceship would be stretched and crushed and obliterated (thousands of miles before it even entered the first black hole). I mean these things bend light, what do you think they’d do to your cockpit? Or your spine for that matter?

Secondly, the instability means that the wormhole would probably not be there long, and could disappear while you’re in it. What you said basically. To use jackm’s example with the needle, a wormhole is like balancing two needles on top of each other, and then trying to persuade an ant to walk up to the top without falling off.

Thirdly, we have no idea of knowing where the second blackhole leads to, since we can’t even send an electromagnetic signal through it to find out anything about the exit. It would by definition be a one-way journey, possibly even to another time-space continuum altogether. Or even to a parallel universe, who’s to say?

@Mat74UK A wormhole is so unstable that even a single particle travelling through it may collapse it. It is not a feasible form of travel unless we can find a way to create one (remember they have never been observed), control where the other end is to be, and find a way of making it stable enough for a person or a spacecraft to travel through.

Ollie the family guy weather guy says ” Black holes is Black ,Worm holes got worms!!!
