I read that article this morning. One of my good friends has RP and sent it to me. He can't see at night right now and will be fully blind in 20 years so this is great news. Personally, I'm waiting for the one with 20/10 resolution and IR night vision so I can pop one of my eyes out and replace it with one of those.

I know this is off topic but I didn't wanna make thread about it, and my question is science related. What is the acid or solution this guy is using to dissolve things safely in a bottle?

Well, I can advance to you that this is a hoax.
There is a picture that shows he uses compressed air to make the drum turn.
The question is: why doesn't it work? The evidence in the beginning of the video seems convincing enough. What is missing?

Air resistance, friction, demagnetization, and of course the laws of thermodynamics.

The laws of physics are not ones to fvck with.

While energy is conserved, there's always losses in friction, air, heat, etc...

Not sure if you were trying to answer my question...
Anyways, wrong answer.

By Irene Klotz

BOSTON (Reuters) - Scientists are still sorting out the details of last year's discovery of the Higgs boson particle, but add up the numbers and it's not looking good for the future of the universe, scientists said Monday.

"If you use all the physics that we know now and you do what you think is a straightforward calculation, it's bad news," Joseph Lykken, a theoretical physicist with the Fermi National Accelerator Laboratory in Batavia, Illinois, told reporters.

Lykeen spoke before presenting his research at the American Association for the Advancement of Science meeting in Boston.

"It may be that the universe we live in is inherently unstable and at some point billions of years from now it's all going to get wiped out," said Lykken, who is also on the science team at Europe's Large Hadron Collider, or LHC, the world's largest and highest-energy particle accelerator.

Physicists last year announced they had discovered what appears to be a long-sought subatomic particle called the Higgs boson, which is believed to give matter its mass.

Work to study the Higgs' related particles, necessary for confirmation, is ongoing.

If confirmed, the discovery would help resolve a key puzzle about how the universe came into existence some 13.7 billion years ago - and perhaps how it will end.

"This calculation tells you that many tens of billions of years from now, there'll be a catastrophe," Lykken said.

"A little bubble of what you might think of as an 'alternative' universe will appear somewhere and then it will expand out and destroy us," Lykken said, adding that the event will unfold at the speed of light.

Scientists had grappled with the idea of the universe's long-term stability before the Higgs discovery, but stepped up calculations once its mass began settling in at around 126 billion electron volts - a critical number it turns out for figuring out the fate of the universe.

The calculation requires knowing the mass of the Higgs to within one percent, as well as the precise mass of other related subatomic particles.

"You change any of these parameters to the Standard Model (of particle physics) by a tiny bit and you get a different end of the universe," Lyyken said.

Earth will likely be long gone before any Higgs boson particles set off an apocalyptic assault on the universe. Physicists expect the sun to burn out in 4.5 billion years or so, and expand, likely engulfing Earth in the process.

(Editing by David Adams and Todd Eastham)
So they say it would propagate at light speed. We would literally see the end of the universe heading for us years after/before it happened, depending on your frame of reference.

Turns out I was wrong about the whole "seeing our demise" thing. A guy in one of my classes corrected me. Because the speed of light is as fast as information can travel, we wouldn't see anything happening at all. One minute we're here, the next, nothing.

Also, telepathy might be an option in the not-too-distant future

Good point. By the time we could "see" it, it would have technically already wiped us out, before we could process whats even happening. I'd like to think thats a pretty easy way to die..

Mash, WTF are we looking at here? All I know is that it's the Higgs data

The plot is for collisions at the LHC (specifically the ATLAS detector) where the resulting particles are 4 leptons, i.e. 4 electrons or 2 electrons and 2 muons, or 4 muons. The x-axis is the total energy of the 4 leptons and the y-axis is the number of events at that energy. The black dots are the datapoints and the black lines around them are the error bars. The plot builds up as more data is available, you can see the date at the top. sqrt(s) is the energy of the collision and the 20 fb-1 is the total number of collisions (that unit is standard in particle physics but sounds a little weird...it's inverse femtobarns which is an inverse area, but the important part of that is that as the number goes up, you have more statistics).

The red and purple area that builds up along with the data points shows what you would expect to see from standard particle physics interactions that are well known EXCLUDING any Higgs interactions...so if the black dots match up with the red+purple area, then there is no Higgs. You can see that after a while, the data points start to get much higher than the background estimate around 125 GeV. This is a hint of new particle with a mass of 125 GeV. It then zooms in and shows a new light blue area, which is what is expected from a Higgs interaction with that mass. So it's essentially showing you how the Higgs was discovered.

This is only for one specific type of Higgs decay, namely the Higgs decays to 2 Z-Bosons, which then each decay into 2 leptons. Other channels show similar results, but I believe this one is the most convincing.

Also, the green area in the bottom is (as the y-axis label shows) the data points minus the background, so any sort of excess there would be a new particle.
