I wonder what his take on antimatter/dark-matter is? Is it something which is being created in the LHC?
Dark matter isn't being created in any human experiment yet.
When matter/antimatter is created, what happens is merely that energy goes from one form (kinetic energy in particles) to another (rest mass of matter). The same would go for dark matter if it was ever going to be created in an experiment.


Sorry Almanildo, you are right. The LHC is not yet creating dark matter, but that is one of the aims:
"We need to study dark matter directly by detecting relic dark matter particles in an underground detector and by creating dark matter particles at accelerators, where we can measure their properties and understand how they fit into the cosmic picture."
from:
http://www.uslhc.us/LHC_Science/Questions_for_the_Universe/Dark_Matter

So, how would the law of conservation of energy apply to dark matter and dark energy?
Current theory states that dark energy is homogeneous and makes up 70% of the universe (with visible matter being 4% and dark matter 26%). I realize at the LHC they have only regular energy to use...

LHC is supposed to start back up on Feb 15th, and the proton beams are expected to reach 99.9% speed of light on December 21st 2012. (lol, just kidding. it's actually slated for sometime in 2011).

I would assume that he also does not believe in a "soul" (defined however you want) and that humans (and any other intelligent life) are simply the sum of their biological components. (like God, the existence of a soul cannot be proven. I'm not trying to prove it, but I like to think that we are more than an amalgamation of cells and electricity)

Also, what about observability? Is it possible for something to exist outside of our observable universe? Mathematically, we need 10 dimensions (+time) for string theory, so what if our observable universe is in a subset of those 10 dimensions, and there are many other universes for which it is impossible for our universe to interact? If you accept that, then one could argue that our big bang was caused by an unobservable event that took place in other (disjoint) dimensions. So, it's possible for "god" to exist (in another subset of dimensions), and to have created our universe, but it would be impossible for that "god" to interact with our universe in any way. I don't think this "god" is the God that religions speak of, nor the one that Scott the protagonist is trying to disprove. But I still think it's important just to point out that he was not thinking of extra dimensions...

"All this sounds like science fiction..."
Am I the only one whose sick of hearing this used all the time in consumer level science programs?


No, you're not. This whole video is... wait a minute, I'm talking to a freaking robot. *ahem* Sounds like science fiction...

Energy has mass too, though it's probably more correct to say that mass and energy are equivalent.

Yes, my mistake- I think my high school science is insufficient. And as they have mass, albeit a very tiny amount- I guess they are "matter" and not energy? >> ^rychan:

From the video "he had discovered particles of anti-matter"
Wouldn't positrons be "anti-energy" as they don't have any mass? - and if they follow the same rules as an electron - not quite a "particle".

Electrons (and positrons) have mass.

When I heard about the seemingly spontaneous creation and destruction of particles, as described by this theory, I was immediately struck that this is probably related to the big bang. The universe as we know it, spontaneously created from nothing and eventually disappearing again, on a time scale unimaginable by we who popped up in the brief moment between.


They're probably not related at all since "before" the big bang, space and time didn't exist, which is not the case for spontaneous appearance of matter and antimatter pairs. Also, we have no theory that describes what happens at the time of the singularity, or "before" it, as opposed to QED.

Your video, The Dirac Equation... What is antimatter?, has made it into the Top 15 New Videos listing. Congratulations on your achievement. For your contribution you have been awarded 1 Power Point.

fake

There are no real videos on the internet, didn't you know that? Somewhere in CERN there's a fake viral video generator that feeds the masses with clips to numb their sense of reality!

HAHAHAHA, THE TROLLS ARE OUT! GOOD, NOW WE CAN KILL THEM OUT IN THE OPEN AND CLEAN OUR BRIDGES.



KILL THEM WITH A LOT OF FIRE!

Right on antimatter. I missed this on the first pass thru. I thought my god could GB actually be right about something? Could the US gov actually have employees so dumb as to right a EULA like this? So I went to cars.gov and no way could I find this page, so I watched the vid again to see if I could figure out how he got there. And there it was at the top of the page "Dealers Support" So self I says to myself Glen Beck really is a lying f**ker, this only applies to dealers. But wait its worse than that, as far as I could tell to get to that page you have to actually register or at least begin to register as a dealer. That means that Glen's outrage and fear mongering is a total fraud because he knows it applies only to dealers or he's just an idiot that has been set up by some writer or staffer who led him to believe that this applies to everybody.

Doesn't Hawking radiation escape from a black hole?


If you define "escaping" as moving away from the black hole from within the event horizon then no, Hawking radiation doesn't technically escape from black holes.

Pretty much anywhere in space there are pairs of matter/antimatter particles that appear spontaneously and then destroy each other. However, on the event horizon of a black hole these pairs often get split... one falls into the black hole, but the other escapes as a form of radiation. It doesn't actually come from inside the black hole itself.

The audio felt kinda like GlaDOS in Portal for a second there...

This is a great video. Good Q&A, good PR for cern.

While watching Angels and Demons in the theater, when they first showed the antimatter trap/bomb scene, my friend and I busted out laughing! Those folks seated around us were confused and not amused.

The design of the Vatican archives didn't make much sense to me either, but I didn't really care about that.

Man, the antimatter is screwing with the sound!
