Are you saying that Futurama is wrong?
Ooooh, a lesson in not altering the past Mr. I'm my own grandfather.
At any rate, the "Grandfather Paradox" mentioned in the quote is a pretty common one with regards to time travel. I don't know, however, if I'd call it a statement about physics exactly... it's sort of straddling the border between physics and metaphysics.
Also, TOGS, there are other possibilities here. But I don't want to encourage the various and sundry internets who like to discuss metaphysics so I'm not going to say anything more.
I came to this thread to see a large hardon collider and was severely disappointed.
Where are all the Small Hadron Colliders?
In your girfriends vajina
Large Penis Collider!
some dumbass was going on and on about how they've been making black holes there already. i said that was amazing since it wasn't getting turned on again til like december and even then- not til after xmas will it be full power.
if it was really bad enough to destroy the universe- wouldn't aliens stop us?
Large Hadron Collider LHC is repaired It will break again or do we will finally gets answers about Higgs boson? ;-
I hope we get some answers about the boson particle. Sounds pretty interesting.
They exceeded the world record for power or something the other day...over 1 trillion volts i think.
sec let me find a link.

But I'm just happy that the fucking fearmongers finally shut up about Black Holes.
honestly it's not quite clear what they're talking about here, and especially since this news bit was delivered by a lay reporter they're using imprecise language.
however, they probably do mean a 1.18 TV accelerating potential (or equivalent thereof)l. considering this is a particle collider, what matters is the energy per particle, not the energy of the entire particle beam pulse. thus probably each proton in the twin beams has 1.18 TeV of energy. (I mean kinetic energy, of course...)
And this isn't even with the beams at even close to full power. The maximum power of the LHC is be 7 TeV. Physicists say some experiments can be conducted at 3.5 TeV, or so I've gathered from sources I've read which again may or may not be accurate...
well, just to slightly correct your terminology, what they what to detect is the Higgs boson, which is the carrier particle for the "mass field," or whatever the technical name of that is. in that sense it's sort of analogous to photons which are the carrier particle for the electromagnetic field. just as photons mediates electromagnetic interactions, the Higgs boson mediates mass effects (no not the one from the fucking game), such as momentum.
bosons in general are particles whose wave functions interfere constructively with each other. to put it in easier to understand terms, basically they tend to go to the same state (i.e. the same position, the same speed, etc.). the opposite of bosons are fermions, which tend to want to be in different states. electrons are fermions, and their dislike for each other is what's primarily responsible for how electron orbitals fill up.
lol semantics.
togs: yeah, I did say or something, i knew my wording wasn't right, i was just being lazy.
sycld: yeah, higgs boson, i know. again, just being lazy lol.
That's a really interesting theory. I wonder if there's a way to get a hold of those papers. I'd be interested to read them.
obligatory staying-in-character edit: I mean, if I could get a look at his reasoning I could probably figure out if he's right or not and change the face of physics for all time. Then I will use my acquired knowledge to build a time machine so I can have sex with Marilyn Monroe.
yeah good try convincing us you're just fake conceited
Tough room
well you can't really count sycld i mean he hates everything nowadays
