AI Thread Summary
Brian Austin Green discusses a concept he refers to as "fuel" related to a quantum field that supposedly drives an outward rush of space. This idea is likely referencing either the inflationary period or dark energy, although it is unclear how these relate to a quantum field. The discussion critiques the validity of pop-science presentations, suggesting they prioritize entertainment over education. The portrayal of the Big Bang as an explosion in space is deemed inaccurate and misleading. Overall, the consensus is to rely on textbooks for a proper understanding of cosmology rather than pop-science interpretations.

Starting at about 15:15 in the video, he talks about a "fuel", related to a quantum field, that provides outward rush of space, and its virtually possible to use up. What is he talking about, anyone know? Sounds a little funny to me!

Thanks.

This is a pop-sci presentation that I would not take seriously. The "fuel" he seems to be talking about is either whatever it was (we don't know) that fueled the inflationary period, or dark energy although I'm not aware that either one is a "quantum field", or what he has in mind for that in this case. In any case, I would suggest you learn cosmology from testbooks, not pop-sci presentations.

In the very brief amount of it I watched, he illustrated the big bang as an explosion in space which is just silly. He knows better, but pop-sci presentation are not education, they are entertainment.
 
Pop science videos are not valid references for PF discussion.

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##.
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...
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...
