Are you saying that Futurama is wrong?
Because he was always...saved from that bus.Quote:

Ooooh, a lesson in not altering the past Mr. I'm my own grandfather.Quote:

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.

There is a small one.Quote:

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?
Maybe it keeps getting delayed by humans time traveling to stop us from running it. :shifty:Quote:

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.

They did collide some particles recently.Quote:

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.Quote:

(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.Quote:

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
Even if you were mocking yourself, albeit poorly, you could have certainly done it better.Quote:

i like hadron colliders of braggable proportions and the higgs bosons they squirt out when you get them energized.Quote:
