Did your cable remote get you stuck on Fart's News again? That will distract you every single time.

I doubt that they're reading this from the shadows and that it has any effect on their religious convictions, but you do your thing if it makes you feel any better.

Never say never. This website also has former believers. Just because you don't see a sudden "You know guys, I was wrong" in the moment, does not mean the seed of doubt doesn't get planted. I used to believe myself.

You used to frequent the forums as a believer? I used to believe as well, but that was very long ago, I didn't know about AF back then.

Read the wiki article, those are the experts. I would assume that after the distances between galaxies become so great, if the expansion continues it would end  up pulling those things apart too, but again, that article explains it better than I can.

Depending on who wrote the article, I'm likely as much of an expert. So the crucial point is that for such a 'big rip' to occur, one needs to postulate an extreme form of dark energy which increases in density without bounds as the universe expands. This is rather unusual, and current observations do not really suggest that something like this will occur. The simplest version of dark energy is the cosmological constant (which is a standard part of Einstein's theory anyhow) and it is so far nicely compatible with observations afaik. With this simplest hypothesis, constant dark energy density, the universe approaches an exponential expansion with a *constant* Hubble constant, which will just go on in a stationary fashion with a constant, negligible force on objects smaller than a galaxy cluster.

You're a physicist, right?

Yes. So, I did my masters and phd in particle physics and quantum field theory, and the research I have done covers collider physics, extra dimensions, unified field theories, string models and some dark matter stuff. In my recent work I have specialized on the physics of the Higgs boson at the LHC. I am not exactly a specialist for general relativity and gravity, but I have dealt with it in my research and have an okish working knowledge.

What does that have to do with jack squat? Does it matter what medium, face to face, or newspaper or TV or radio that someone you hear says something to cause you to say to yourself "I never considered that"?

Is there some magical power about social media on the internet that prevents doubt in the believers who frequent it?

I started doubting long before the internet. I think social media makes it even that much harder for bullshit claims to hide.

That's seriously awesome.

That's seriously awesome.

It is a fascinating field, but in the end it is a specialized job like many others.

Great, certainly makes me feel like a retard. But still, when Krauss says even nothing is something, why cant it be that that the state of nothing, which we all agree can lead to something, even he said in that prior video that "nothing is unstable". I take that to mean there is a twitch there in that "nothing"  produced by "something".

Which makes me keep thinking the finite part is nothing, because it is unstable leads to something, which also has a shelf life, which is also finite. So I keep thinking all this is a cycle from off(nothing) to (on) something back to off again, and so on and so on.

This retard, me, can only agree that no matter what a magical puppeteer is not required to fill in the gap either way.
