Shorter you tube. This man thinks dark matter is in another universe.

Thanks for the link, it's not working for me.
[edit]

This video contains content from Discovery Communications, who has blocked it in your country on copyright grounds.

The link doesn't work from the US or UK.
Does work from an Amsterdam or Brussels IP address.
Google sure does work hard to keep Government and Corporate bosses happy.
i'll try to find a stream that works in the US/UK.

Through the wormhole s01e08 Beyond the Darkness

The above link seems to work from a Washington IP address.
Maybe ok in the US.

At first it wanted to download some media player HD.
i have NoScript add-on to Firefox running.
Didn't download any file, just kept allowing more permission till finally the video would play.
Not sure if it's wise to punch holes in your firewall even if only temporary.

If interested a download from torrent only takes 20 mins.

The first link seems to work for the UK, and Canada, so should work for outside the US.
May they find it useful.

What is the Universe Made Of?

Yes, the title changed. Dark energy, can't be found. Yet, 72 % of the universe is made up of dark energy.

Occams Razor, thing going on with both the matter/energy.

Suspected to be the cause of the universe expanding.

Let me add=> and that at an increasing rate.

Thanx for changing the thread title Lynn:) I was going to suggest that.

Your welcome, Julie :)

Then the question is, where is the universe expanding to. Is it going to go out with a Wimper, or a Bang??

All a question of Entropy and Information?

S=klnW is written on Ludvig Boltzmann's grave in Wien, so I was told. He killed himself in Duino, where Rainer Maria Rilke had written his "Elegies". Probably he felt misunderstood by his peers.
Now they say that entropy is proportional to the area of the surface of the events horizon surrounding a black hole. I wonder what Boltzmann would think of this.

A sad end on all counts.

The event horizon proportionality is also called the 'holographic limit to information'. That suggests that the Canadian quantum computer is an impossibility if it is supposed to be truly quantum... However, can they dodge the limits by claiming/ operating some form of fast superconductivity simulated annealing?...

I just don't know enough to answer your question. But a friend of mine and former colleague at Elsag ,Genoa, Giuseppe Castagnoli, and prof. Mario Rasetti of Torino Polytechnic University have developed a method of "simulated annealing" already in the Nineties. An article on this subject was published jointly by Castagnoli and me in the Italian edition of MIT Technology Review in December 1996. Its title was 'Le altre dimensioni del problema" and it has a bibliography. I know that Castagnoli, now retired from Elsag, as I am, is still working on quantum computers.

How do you measure something that is invisible?



Can you match each galaxy in the top row with its warped counterpart in the bottom row? For example, is the warped version of galaxy A in box D, E, or F?

How do you measure something that is invisible? It's a challenging task, but astronomers have made progress on one front: the study of dark matter and dark energy, two of the most mysterious substances in our cosmos. Dark matter is intermixed with normal matter, but it gives off no light, making it impossible to see. Dark energy is even more slippery, yet scientists think it works against gravity to pull our universe apart at the seams.

Those are 'too easy' by just looking for the mix of colours. Can not instruments do the same by looking at the spectrum counts?...


So... Is this a "Galaxy Zoo" follow-up to try to classify Einstein rings and other gravitational lensing?

The LUX experiment (Large Underground Xenon) has found no trace of dark matter WIMPs (Weakly Interacting Massive Particles). So the question is still open.
