Interest in blackholes and whiteholes

AI Thread Summary
Black holes and white holes are central topics in astrophysics, with white holes theorized as the opposite of black holes, expelling matter instead of absorbing it. They are considered hypothetical due to potential violations of the second law of thermodynamics, although some speculate they could serve as connections between different points in spacetime or even different universes. There is a notion that quasars might be white holes rather than supermassive black holes, and some suggest that the Big Bang could be viewed as a massive white hole. The discussion also raises the intriguing question of whether our universe itself could exist within a black hole. Overall, the existence of white holes remains a contentious topic in the field of astrophysics.

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?
 
Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
