Physics, Astronomy & Cosmology / What is the cosmic microwave background?
« on: 08/10/2019 15:36:31 »
Could somebody please explain this to me better than anybody else has so far?
My understanding of the CMB is it's some kind of leftover from the big bang. But just how is that possible when 'we' (all the atoms that make up you, me and our local universe) were part of that big bang?
Isn't it like seeing a lightning strike hit your garden shed before breakfast, but not actually hearing the thunderclap until after supper!
I just dont get how my atoms have managed to get where I find them today ahead of all those other atoms/photons/whatever that other sciences would suggest have travelled umpteen billion lightyears in distance a good deal faster than my own humble bits of matter could have done.
Just WHY are we still seeing this stuff that should have TOTALLY dissipated out of eternity a few umpteen billion years ago?!?!
Any answers, please?
