Recent studies have cast some doubt on this often-cited indirect-evidence of dark matter. If you assume that galaxies have super-massive objects at their center, the observed gravitational effects can be explained without the concept of widely distributed dark matter. Now, some scientists are suggesting that the center of galaxies may be super-massive objects made out of… you guessed it: dark matter. And so it goes. ---

I frequent the [phys.org](http://phys.org) comment sections and DE/DM is one of the most contested points among other readers. It seemingly spits in the face of what we know about entropy. For example, DE is the vague explanation for why our universe’s expansion is accelerating. Imagine a throwing a sleeper only to watch the rotational velocity increase. It’s hard to reconcile in the Standard Model. On a lighter note, did you know that at any given moment, there are galaxies that are moving away from each other FASTER than the speed of light? This is due to the expansion of space-time and the huge distances between some galaxies. Pretty wild to think about. ---

Yoooo! I’m a physics major and I just found this thread, lots of interesting talk here. I’ll be following this one. One note of point I want to make is that a lot of information gets pretty clouded when you get from the math heavy experimental results of many experiments to what’s going on in layman terms. It’s always important to note where information is coming from, and what evidence it does or doesn’t have. Cheers! ---

The universe is indeed a strange and wonderful place. Of course; Einstein would say that the galaxies only _ **appear** _ to be moving apart at the speed of light; relative to the other. It would be very interesting if we could build telescopes capable of seeing this ultra-distant ‘horizon’ (what like 50 billion light years?). We would be able to watch entire parts of the universe fade from view constantly. ---

Something wild about astrophotography that kind of blew my mind is the fact that the majority of stars you see in them (such as a the photo you posted here) are actually in our own Milky Way galaxy, they’re not stars in another galaxy as they’d be too dim to see. So what you’re actually doing is seeing stars thousands of lightyears away while the nebula is millions of lightyears away. ---

There has been considerable work on revising the laws of gravity over large-distances to account for observation. Many believe that modifying the laws of gravity is preferable to inventing entirely new forms of matter and energy that are difficult; if not impossible to detect. It is simply impossible to understand the effects of gravity without understanding the Einstein tensor-metric; and how it affects space-time. If nothing can move faster than the speed of light; why is effect of gravity instantaneous, over infinite distance?
