Large Hadron Collider - Up and Running

[EvGa]

Large Hadron Collider becomes world's most powerful particle accelerator.

Scientists at the Large Hadron Collider at Cern near Geneva are celebrating a major milestone after the machine broke energy records overnight to become the most powerful particle accelerator in the world.

At 12.44am this morning, the LHC accelerated beams of subatomic particles to higher energies than any achieved before in a collider.

Inside the particle accelerator, two counter-rotating beams of hydrogen nuclei are whipped up to more than 99.99% the speed of light. At four points around the machine the beams are crossed, steering the particles into high-energy smash-ups. The collisions recreate in microcosm the conditions that existed moments after the big bang.

Scientists hope that when they sift through the subatomic debris they will find particles that are new to physics, such as the Higgs boson, which gives mass to elementary particles, and possibly particles of dark matter, an elusive substance that clusters around galaxies and accounts for most of the mass in the universe.

Thought this was pretty interesting. Excited to see what they discover.

they won't be doing the *real* test until next year though.

[PhoenixRider]

And then it'll fail and will have to be repaired again.

[[SD]Master_Wong]

well something as powerful of this is hard to keep in working order its amazing they even did a low power test considering the science behind getting something to go so fast

going to be good when its running at full power

[antics]

im sure this will open much more possibilities for us in the future

[Reise]

More than 99.99%, eh?

Wouldn't that be 100%?

[Jstar1]

and then they will make antimatter, a clean energy source that will power america for the next 100 years and let earth conquer our galaxy

[EvGa]

More than 99.99%, eh?

Wouldn't that be 100%?

99.991% is more than 99.99%.

Technically, there are infinite amount of numbers between 99.99% and 100%.. I think.

[Reise]

Right, I'm just poking at the word choice.

Logically one would see "more than 99%" and perceive that as 100%. Of course brainy scientists care about numbers running into the millionths place and onward.

[ryan1166]

This will be the end of the world.

/sarcasm.

Can't wait to see what happens.

[EvGa]

Did a little more reading.. Apparently, if this collider doesn't detect the Higgs Boson, it simply doesn't exist. That would be a huge blow to current particle physics.

travelling at the speed of light is impossible as theorised by Albert Einstein

also by modern science we dont have the energy needed to push something to light speed 99.99% is best we can do with rapid acceleration

Yep, that's why we'll never travel very far in the universe using conventional methods.

Insane:
Code: Select all

huh what?

big point here is most of our technology is based on laws Albert Einstein wrote although i believe there is more to it then makes the eye i doubt we will ever reach light speed .99 of light speed is stil very fast but i dont think its safe that close to light speed

[antics]

is everyone ready?

I was saying.. we'll never travel very far due to the fact we can't go any faster than the speed of light and the fact objects in the universe are millions and billions of light years away, so even traveling at exactly the speed of light, it would take millions and billions of years to get there.

Hence the need for a different kind of travel, wormholes anyone?

Whether or not the human body can withstand those speeds (it can't) is irrelevant since we can't (yet) live that long..

Crazy stuff, I love astronomy, quantum physics, etc..

mhm. You sir are correct.

there are things in our universe that can travel faster then the speed of light otherwise light would be touching the edge of our universe and we would prolly notice it

dont think so that is one thing that is easy to break and bend possibly the weakest force you could know about

[CeLL]

what the fuck are you talking about?
you said "there are things in our universe that can travel faster then the speed of light"
i said gravitation.
you say no because it breaks easily and can be manipulated easily. what the fuck do you think you are staring at right now, bent and manipulated light. wanna break that light, turn off your moniter.
gravitation is faster than the speed of light. do you honestly believe that if the sun just completely disappeered that it would take 8+minutes for the earth to feel the lack of its gravitation? with out the gravitation associated with the sun our galaxy would fall apart pretty fast, if not almost instantly.

[[SD]Master_Wong]

the larger the mass the larger the gravity but we would see the light fade before we feel the effects of the lack of gravity

in the center of each galaxy i assume there is a group of super stars which can hold this all together either that or the group of stars themselfs create a larger force of gravity

[CeLL]

yes gravity is not a constant and changes with the size of the mass of an object, but im not talking about gravity, im talking about gravitation.

[Miguez]

Space now seems much more interesting.

About the LHC, one of my teachers was talking about it, I didn't really pay much attention to it though.

[Devilman]

Physics is an amazing subject :) I sincerely hope the black hole thats created after the LHC crashes won't be big enough to swallow all of Europe -.-

AFAIK there are supermassive black holes in the galactic nucleus(the center) and those black holes are holding the contents of the galaxies together. My 2 cents

that sounds so awesome

The universe is expanding faster than the speed of light many billions of light years away from us, but nothing is actually moving faster than the speed of light.. space itself is expanding..the space between galaxies. It's hard to explain, you'd have to read up on it. It's like gluing pennies to a balloon, blow the balloon up, each penny represents a galaxy.. the space between them would expand, but not the galaxy itself.. the surface of the balloon is space. There are places (that we obviously can't see) 14-15billion LY away (i think, need to look up the number) that are spreading away from us at faster than the speed of light.

The general consensus is gravitational waves travel at the speed of light. According to Newtons calculations they don't, but Einsteins (newer, widely accepted) equations show that it travels at the same speed. Where the sun to instantly disappear (which it can't), the Earth would feel gravitational affects for another 8 minutes before floating off into the gravitational field of the next large abject.

I just read about this same question last week in my Fabric of the Cosmos book, but instead of using the sun they asked, what if the moon disappeared. Pretty simple book, but it gives good examples to explain. I'll look it up after class.

There are supermassive blackholes in the center of most spiral galaxies, but not all galaxies have them. Ours does.
