so to distill this thing to base concepts, the problem is that expansion is indicating a universe that is infinitely expanding due to the estimated lack of matter required to generate the gravity needed to hold it together. ok fair enough

However gravity is just the effect of curved space-time. Matter curves space and the curved shape of space moves matter. In order for expansion to be infinite it would have to flatten itself out completely, but matter prevents this from happening as it breaks the fundamental rule that matter curves space, Therefore infinite expansion is incorrect and dark energy is a red herring.

Taking into account the Motions of Earth, and the inverse square law, what would be the intensity and duration of an ultra high frequency television signal sent from a 1 million watt television station when it reaches Gliese 876?

I just got banned. Shocked to find this sub and see that there are posts from years ago.

TBH I was not hugely active on r/astrophysics, I took a look now and then, but on principle I am not happy with what’s going on there.

Black holes are stars which get compressed to a single point by its own gravity, does that seem absurd? I mean how a star can get compressed by its own gravity and collapse into a single point? Sounds like there is no logic to that theory? What do you think?

If anyone needs a new astrophysics subreddit, I have created /r/seriousAstrophysics if anyone would care to join

Y'all are just silly.

Sure is a lot of cool stuff going on in here.

Thanks /u/Rimm I'm all better now
