Ok, as a particle physicist I'll clear a few things up here... ;)
a) The speed of the particles is, as stated above, not EXACTLY the speed of light, but something VERY close, so in popular publications one does often not bother with the difference.
2) Yes, surface temperature of sun is about 6000 degrees (celsius or kelvin, almost the same here) so the temp of this plasma would like... a lot. But as it is very small (around 10^-14 meter I'd guess...) and exists for a very short time (what was it? 10^-lots secs) the actual heat it radiates in this time will be very small...
C) Black holes radiate (hawkings radiation). The smaller, the faster. So small black holes will explode very fast. I'm not 100% sure (someone look it up if you want...) but I think that even if you use a substantial part of the earth's mass converted into energy and pump it into this black hole, it will explode again within a fraction of a second... Then it's fairly unrealsitic to do even that...
"Ok guys, we want to collide these elektrons. Were do we find the energy? hmm, lets take the Alps!"
And you would need an accelerator maybe the size of the galaxy? That's a guess, but I'm positive an accelrator of the size of the solar system will take you to a maximum of around 10^19 GeV which isn't even nearly enough...
4) just needed another number to show off the lack of consistency of the enumeration.
epsilon) sry for being scientific CoR... tried to keep it as unserious as possible. |

1) popular publications they may be, but when publishing something related to quantum mechanics, if you are a particle physicist, you would know that there's all the difference in the world between 99.9999% the speed of light vs. speed of light. basically, the publication if it is scientific, stated this falsely, which makes this article crap. i mean if you could accelerate anything and for god's sake, gold protons, god, at that speed isn't it highly likely they'll break into quarks, nullifying the experiment?
2) if and only if although definitely almost impossible, you manage to create a warped space that lasts long enough to get some data off it, i think the latest paper my professor was talking about states that it can't be done by collisions on earth. maybe possible if you manage to condense enough mass into extremely tiny space. with our technology? please, and even for the next millenia i doubt it.
3) i agree with first half, i've no clue about the last half |
