Strange edit

For a second time User:Noz92 did a complete replacement [1] of the article, I reverted again for these reason:

old content, includeing referencesm was deleted
new content not very layman-friendly
it's Schwarzschild, not Swartzchild. If you don't know this, there a some doubts about your qualifications to edit this article

Can somebody who speaks Japanese check the edit by 166.121.37.7. The old link was an actual article while the current one looks like the notice of no article yet. --Laura Scudder | Talk 00:09, 19 Apr 2005 (UTC)

Reason for removing the 'Hitchhiker's Guide to the Galaxy' edit

I've noticed a few times on WP that people mention things along the following lines: 'in the science fiction series blah blah blah, ... one character falls into a wormhole and blah blah blah'. It might be OK to mention stuff like that in non-scientific articles, but in the middle of scientific ones is a little out of place. Perhaps a little section on science fiction is appropriate in the scientific article (especially for controversial ideas like wormholes) - something like the article Alcubierre drive (if I remember correctly).

Bubble universe

The Universe is mostly considered to begin with the Big bang. However, Big Bang in fact IS possible to happen more times, but the problem is Big Bang was "the beginning of time" which gives no time for other particles to behave like it could in the Big Bang. That problem is still a mystery and not even I can talk for sure about it. Some people even think Universe is expanding because of a White hole, which is defined to have anti-gravitational properties.

If big mass objects curve spacetime and creating gravitational field, that means white holes should have negative gravity which requires NEGATIVE MASS! That is physically impossible, UNLESS; negative mass should have less mass than space-time itself, which can only happen if white holes are places in Universe where universe somehow didn't expand. That is the only explonation, even tho it's also hard to happen because there should be SOMETHING blocking the Universe(which expanded 300 000km/s) in no space or time. It is impossible and it is considered still until we find a Real White hole.

Supermassive Black Hole abbreviated SBH

Throughout science, there's a move towards uniformly abbreviating supermassive black hole as SBH. 104.190.63.217 (talk) 18:22, 14 January 2023 (UTC)[reply]

No references in Physical relevance chapter

Where are the sources ?

I'd like to say by the way that black holes don't get formed. They were already there before the supernova. Compression in a supernova for instance is temporary. Temporary compression cannot yield a stable black hole, it's like thinking that after a nuclear explosion, is found a nuclear reactor. It's the same absurdity who claims that each supernova creates a black hole.

As references for my own remark, you can read : The first published model https://hal.science/hal-01673630v4 A description of black hole eruptions in http://pubs.sciepub.com/ijp/7/4/4/index.html For a more advanced description with more proof http://pubs.sciepub.com/ijp/9/1/5/index.html The "Big Bang" black hole https://journals.scholarpublishing.org/index.php/AIVP/article/view/15578

By the way in the last peer reviewed article on the "Big Bang", I mention a white hole case, on Jupiter's surface.

Metric needed

You need to show a white hole metric. — Preceding unsigned comment added by 97.73.100.49 (talk) 04:52, 1 December 2024 (UTC)[reply]
