Interest in blackholes and whiteholes

In summary, white holes are hypothetical celestial bodies that can spew out matter, and they may exist in our universe.

i like astrophysics so much! But have particular interest in black holes and white holes and the big bang!


In astrophysics, a white hole is a postulated celestial body that spews out matter, in other words an anti-black hole, or the time reversal of a black hole.

It can be a means of transport between points of spacetime and even different universes. A matter that enters through a black hole might come out of a white hole. For example an astronaut that got suck into a black hole will come out of a white hole. Although, sadly, he would be crushed up terribly, but the exact number of atoms that made up his body will come out of the white hole. The existence of white holes is hypothetical, as they appear to violate the second law of thermodynamics but the laws of physics that apply in our bubble universe will not be the same in other bubble universe.

Other speculations include the hypothesis that quasars are actually white holes instead of supermassive black holes.

It is possible that a white hole is created out of an anti-matter star when it explodes. As it is the opposite of a black hole. An "anti-black hole". white holes have a high chance of existence in our universe as you can say our universe is created out of a massive white hole. The Big Bang which spews out matter.

although my article talks about white holes, i don't think its possible for them to exist as they would violate the second law of thermodynamics!

Welcome to physicsfourms,Whiteholes(Frist time there is a username that has sam the name as his frist post and not being about him/her self)
Good article you worte but can you put links to your sources?

Well we would know if a white hole was near, because everyhting would be too bright, right?

I was just thinking about white holes the other day while looking at this photo

So is it possible for us to be in a black hole ( our "Universe")?

what do you mean? A black hole in our universe? Or we live in a black hole?
 

FAQ: Interest in blackholes and whiteholes

What is a black hole?

A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape it. It is created when a massive star collapses under its own gravity.

How do black holes form?

Black holes are formed when a massive star dies and collapses under its own gravity, or when two smaller black holes merge together.

What is a white hole?

A white hole is a hypothetical object that is the opposite of a black hole. Instead of absorbing matter and light, a white hole would emit matter and light. However, there is no evidence that white holes actually exist.

Can we see black holes and white holes?

Black holes and white holes cannot be seen directly as they do not emit light. However, we can observe the effects of their gravitational pull on surrounding matter and light.

What is the difference between a black hole and a white hole?

The main difference between a black hole and a white hole is their gravitational pull. Black holes have a strong gravitational pull that sucks in matter and light, while white holes have a repulsive gravitational pull that pushes out matter and light. Additionally, black holes are believed to exist in the universe, while white holes are purely theoretical.
