I really enjoyed Tyson's Cosmos series. It's a shame that the series got discontinued.

Indeed, NdGT's Cosmos is as good as Sagan's Cosmos. I enjoy both films, can watch them forever. Much better than stupid tv shows where people constantly interrupt him with lame jokes and crap.

Roger Penrose wrote a new book called
Fashion, Faith, and Fantasy in the New Physics of the Universe

Roger Penrose is definitely one of the most brilliant mathematical physicists ever. He always has some awesome explanations for things that aren't easily understood :D


Brand new video by Oxford Mathematics




edit: so cool, I found a downloadable 720p video :D

edt2: and all other his lectures here

Software A lot.
Benchmark Scores Its fast. Enough.
A recent revival of the idea that dark matter/spacetime is the reason for the speed of light being what it is, the fastest a photon can travel through a medium (aether/spacetime is dark matter?, but not in the MM experiment sense) that we can not directly observe or measure other than by the speed of light itself. If my comment seems random its only as its interrelated to some of the videos you have posted.

@Steevo Interesting, have a link?

Brian Greene


PBS




Dark Matter vs Dark Energy: The Difference Explained
video by Gresham College


I've added some videos to post #153. Interesting that in the second video posted in May 2012 NdGT said that Milky Way is one of the hundred billion galaxies, now we know it's one of the thousand billion galaxies :D

Time doesn't pass. It's just our way of measuring entropy :)

Nice point but there's a good article in Scientific American which makes everything look more complicated.

They ask really interesting question:

In the evolution of cosmic structure, is entropy or gravity the more dominant force? The answer to this question has deep implications for the Universe's future, as well as its past. Arthur Eddington coined the term 'arrow of time', and famously said "the shuffling of material and energy is the only thing which nature cannot undo".
But here we are, showing beyond any doubt that this is in fact exactly what gravity does. It takes systems that look extraordinarily disordered and makes them wonderfully ordered. And this is what has happened in our Universe. We are realizing the ancient Greek dream of order out of chaos.

Some think that Universe is a simulation ... ughm okay ..


Others say that entire Universe could be one giant alien ... Can you imagine that?


And here's some real science (old video though)
