In reply to the discussion: The universe is much bigger than big [View all]opiate69
(10,129 posts)36. I`ll take a stab at one...
when scientists look at the skies and say "there isn't enough matter there... there must be something else, it's DARK MATTER!" i say bullshit. were they taking into account the billions of additional constellations they are finding in these photos? and the billions in the next photos?
That is simply not how the dark matter theory works. Cosmologists looked at specific galaxies, such as our own or Andromeda, and calculated the mass of visible objects (stars, gasses, etc) then compared that to the immense size of said galaxies and determined that, within that galaxy, the amount of mass and the amount of gravity necessary to keep the galaxy from just dispersing into intergalactic space did not compute. These ultra-distant galaxy clusters don`t figure into the equations because the equations are for individual galaxies and clusters, and not for the universe on the whole.

Of course it's just a belief. If it wasn't, we wouldn't be having this conversation.

Question number one isn't really a question, it's a statement and a specious one at that.

a) they were answers to your questions. b) "specious" means plausible-looking falsehood.

It's a baseline assumption that flies completely in the face of all probability.
