AI Thread Summary
The discussion centers on the implications of Newton's 3rd law of motion when applied to the universe as a whole. It raises the question of what reaction would occur if the universe itself were considered an object exerting force. Participants speculate whether such an action could lead to a transformation of the universe, possibly resulting in phenomena akin to a new Big Bang. The conversation also touches on the conservation of energy, emphasizing that energy cannot be created or destroyed. This inquiry invites deeper exploration into concepts like Mach's principle and the nature of cosmic interactions.

what would the reaction to it be? Just suddenly has this question popped up in my mind.

Does this mean the universe would transform into something else through the reaction? Because after all energy cannont be created or destroyed. Maybe a new big bang?

Newton's 3rd law?

Action/reaction refers to force pairs in Newton's 3rd law: If object A exerts a force on object B, object B exerts an equal and opposite force on object A. If "object A" is the entire universe, what could possibly be "object B"? Perhaps you can restate your question.

Thread 'Matter density right after the decoupling'

https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.

Thread 'Rutgers finds a transparent Einstein Cross - apparently a dark matter "halo".'

The formal paper is here. The Rutgers University news has published a story about an image being closely examined at their New Brunswick campus. Here is an excerpt: Computer modeling of the gravitational lens by Keeton and Eid showed that the four visible foreground galaxies causing the gravitational bending couldn’t explain the details of the five-image pattern. Only with the addition of a large, invisible mass, in this case, a dark matter halo, could the model match the observations...

Thread 'Big Bang and Infinite Universe'

Hi, I’m pretty new to cosmology and I’m trying to get my head around the Big Bang and the potential infinite extent of the universe as a whole. There’s lots of misleading info out there but this forum and a few others have helped me and I just wanted to check I have the right idea. The Big Bang was the creation of space and time. At this instant t=0 space was infinite in size but the scale factor was zero. I’m picturing it (hopefully correctly) like an excel spreadsheet with infinite...
