Swift
I'm sorry, but this part of the theory is just well bleh. I mean, you get the atomic sized particles that supposedly come from nothing(though the universe as we know it is already here) and we're to believe that over eons of time that process created enough matter for all the galaxies that we know of today. That's really really shaky stuff. I can see how someone that supports the theory of evolution would very much like the idea though.
Maybe I understand it wrong. But I remember reading the site that famine posted and it was talking about radically minute amounts of matter.
Well, it depends on how philosophical you want to be... for me, it's like this. No-one knows where the original universe (pre-Big Bang) came from... that is, and always will be, a question for philosophers and theologists to discuss....
But what we do know is that the matter that does exist here and now, the known, measurable and observable universe, has a finite mass... and that mass is, and can be measured/seen to be moving rapidly away from one central point.
By measuring the speed, distance and direction of travel of these celestial objects, we can safely say where (in space) these objects used to be, and more importantly, how long they have been moving (or have existed) for.... hence these easily made measurements give us a pretty accurate estimate of the age of the known universe.
Why it exists, and where it came from, we don't know.... but how long it has existed for (relative to the time scales we are familiar with anyway) and the nature of the particles that exist within our universe (protons, neutrons and electrons etc.), we do know... and we know how they behave... we know that in the primordial universe, shortly after the big bang, that matter did not exist as atoms... it was only when the universe cooled that matter, governed by the laws of physics, coalesed into the matter that we are now (by concerted study) familiar with.
The fact that we know in great detail how atoms are structured and how they behave, means that we have also come to understand how molecules form, and hence more complex molecules (like biological molecules) follow thereafter.
The experiments of Miller and Urey showed that basic elements and molecules that are abundant in the Universe (including here on Earth of course) can and will form more complex molecules (including biologically relevant molecules like nucleotides, sugars, amino acids etc.) spontaneously, so long as they are given the right conditions - principally the presence of UV light (from the Sun) and electrical discharges (from lightning)....
