Explain me how at all has something begun? I mean how have matter started to exist? How is there a dark void in space instead of just "nothing" rather than something you can call an area with no matter and no light?
There is the imaginable unimaginable ; a teaspoon of water to an ultrumicrobacterium , the unimaginable unimaginable ; the Pacific Ocean to an ultramicrobacterium -and the Gamma radiation blast, that kick started the Universe, to a human brain.
30,000 tons of material accumulating on the Planet ever year. I would be interested to know what the upper limit of this accumulation rate might be for, say, 60- 100 million years - and what effective gravitational increase may have been imparted to the Earth over this scale of time. I have an idea the Earths' gravity would have been measurably weaker than today and this may have allowed dinosaurs to reach their outrageous sizes.
Mass of Earth is 5,973,600,000,000,000,000,000,000 kg. In the 66 million years since the extinction of non-avian dinosaurs, assuming 30,000,000 kg of accretion per year, mass would have increased 1,980,000,000,000,000 kg, ie a tiny fraction. Insignificant.
Thank you David Deamer
I love science talks
a fascinating talk :)
Hi Prof. David,
A good talk. It looks like, a long way to go to get the evolution in theoretical format !

why sholud anyone that is talking about prebiotic chemestry need to adress those questions?
"hydrogen, given enough time, turn into people" lol.. the universe is a Lego master.
