fascinating speech for the science geeks here.. just thought I'd share.. ;) It really starts at the 8 minute mark.
What blew my mind was hearing that if if all visible matter and energy were removed from existence, it would leave the universe essentially unchanged.
The universe =
30% dark matter
+ 70% dark energy
Earth, and everything we see in telescopes is < 1%.
:wtf:

I remember reading some theory, that the emptiness can spawn matter/energy (rarely) and as the universe continues to expand, the area and sheer time avaiable will make stuff appear out of nowhere eventually. Atoms, Molecules, small clumps of matter, eventually even planets, and given infinity of time and space, solar system just like this from this exact moment will appear.
There was also some calculations about big bang spawning in something like 1 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 or so years...

He mentions this at 20:00 "Nothing isn't nothing any more." ;) We are learning that quantum fields and particles are constantly popping in and out of existence in empty space..and that "nothing" (the vacuum) actually has mass. Crazy ..I love it.

that was a really great video - thank you for posting it.
particularly loved the bit about the quantum fluctuations and the background of 'nothing', as well as the observations on observation...
i have quite an interest in this 'nothingness' as a sort of deep reservoir of creative potential, bohm's 'ocean of the implicate', from which all things unfold more or less randomly.

frrrk yeah. thanks for posting this.

his collar sticking out is bothering me though :mad:

great, thanks for posting.
That dude looks like a child molest0r though...IGK ?

wow, i loved this lecture, i stayed on my ass the entire thing :p i wish my lectures at school were this interesting. i could probably sit through another hour.
the universe is so remarkable..

Very interesting. But, there's one thing physicists say that reminds me of the pre-Einsteinian world. Is there any chance dark matter is today what ether was a hundred years ago?

I think so.. My own gut feeling is that dark matter is really the same as regular matter..only it is invisible to us because it exists in one of the higher spatial dimensions. We are only capable of perceiving 3 dimensions, however M-theory predicts we actually live in an 11 dimensional universe. If there is matter floating around in higher dimensions that permeate the universe, there could be something special about gravity that allows it to "leak" back and forth between the higher dimensions, and that would explain much of the invisible mass we are detecting in our 3D view of things..

Grüße Fräulein, Sturm-Verbot-Führer, Sounds like spam to me, as my brain dump to watch movies, with no indication that moving his hands as the universe expands, but says that if all matter in space and the existence of all the other things that I want to see, but I woke up last thing you want to question the scientific fraudsters send treat gay and gay-jock erotic minors, but if you really look at the top right knowledge, you can learn all kinds of kickass science space, and I live in Houston and NASA is just 20 minutes, many people have two jobs, and hell half the people are morons NASA has studied Catholicism and lost all train of thought, but the universe, if only the universe of men to be free, or something, because it's all freaky weird in all areas of road space, Researchers, but with all due respect, the committee decided to suspend the license immediately leave the building, science as a kind of turbulence or a Dodge, his theories are the worst tripe popular, are weak
