Big Bang ForbiddenEdit

There are viable alternatives to general relativity which forbid singularities such as the Big Bang. This should be mentioned in Wikipedia's Big Bang article.

That section doesn't cite any sources, which is normally a requirement. The statements need sources to even be worth considering, since they won't go onto this page without them. 74.132.8.133 (talk) 13:28, 1 November 2018 (UTC)

What is going on with the caption for the graphic immediately below the words "Part of a series on Physical Cosmology" ?Edit

What is going on with the caption for the graphic immediately below the words "Part of a series on Physical Cosmology" ? If you click on the picture, the caption beneath seems inappropriately long and rambling. I'm not qualified to judge its accuracy, but it looks a little fishy to me. — Preceding unsigned comment added by 2601:645:C000:AF7B:9104:FDB8:FFE5:BF20 (talk) 23:16, 17 November 2018 (UTC)

no beginningEdit

The dying stars are the brightest stars. They and their orbiters are shrinking in size and distance. When we look out as far as we can see the normal emitters are interfered out of view by these dying stars. Therefore, rather than expansion the most visible emitters are simply getting smaller. THERE IS NO EXPANSION, no beginning. Even life that is trapped inside Volcanic rock under the sea has no beginning. It is simply redistributed when a a planet breaks up. — Preceding unsigned comment added by 152.132.9.140 (talk) 11:55, 11 January 2019 (UTC)

Thank you for your opinion. You might be interested to read Steady state model, a theory that I recall Fred Hoyle putting forward very convincingly many years ago. It is now considered unlikely by modern scientists. Dbfirs 12:03, 11 January 2019 (UTC)

Causality Big BangEdit

As the Universe accelerates, after some period loses all innate causal connection among its components and reBig Bangs.
just another theory - we should mention all theories — Preceding unsigned comment added by 2A02:587:4102:8000:9598:4471:8BEA:5385 (talk) 16:35, 9 February 2019 (UTC)

User:Oldstone James confusing editsEdit

User:Oldstone James firstly changed content from "Current conception of the Big Bang model assumes the existence of energy, time, and space, and does not comment about their origin or the cause of the dense and high temperature initial state of the universe" to "Current conception of the Big Bang model assumes the existence of energy as well as currently understood laws of physics and does not comment about their origin or the cause of the dense and high temperature initial state of the universe." which made no sense, and then changed it to "Current conception of the Big Bang model assumes the existence of energy as well as the existence of currently understood laws of physics about their origin or the cause of the dense and high temperature initial state of the universe" which also made no sense. Then it was been changed to "assumes the existence of energy and does not comment about their origin" to what is "their" referring to now? I asked. Please gain consensus here for any further changes.

Please stop edit warring to add confusing content NOT supported by the source, the source clearly states "The Big Bang scenario simply assumes that space, time, and energy already existed" [1] Theroadislong (talk) 20:10, 29 March 2019 (UTC)
