dark matter - the LHC calls for the devil

[christer54001]

no. em radiation is only made of photons which have no mass at all. by your theory, anything that has energy has mass. so if an object is placed on a shelf 1 meter above the surface of the earth, its mass is equal to the potential energy over the speed of light squared. E=M/c^2 is only used in nuclear decay to determine the energy created by the mass lost in a nuclear reaction

[newcome880]

if you look at an earlier post from me you see that I wrote photons have no REST mass, i.e. if photons would rest instead of travelling at the speed of light they would have no mass. But they don't, they always travel (in vacuum) with c.

[newcome880]

no, it would not be instantaneous. It is predicted that radiation caused by the black hole inside Earth would kill all life before the actual implosion takes place. Furthermore the implosion scene IS indeed an implosion scene. No, things that are sucked into a BH are accelerated but they don't move at lightspeed. That would contradict Einstein's theory of relativity which states that matter cannot be accelerated to the speed of light unless the energy for that purpose was infinite.

[christer54001]

If a black hole was created, how would radiation escape it to kill all life? Not even electromagnetic radiation which has no mass can escape a BH so how could anything else do so?

[newcome880]

the radiation I was talking about is part of a theory that predicts it. However, I'm not certain where it would emerge (would have to dig deeper into that theory), I only know that they say it would be caused by the black hole (not necessarily emitted by it). To be more precise: electromagnetic radiation has no REST mass. Indeed it has an energy E=hv (where h is a constant and v the frequency). So you can calculate its corresponding mass by m=E/c² (c=light speed).

I believe dark matter is what was here before the "Big Bang",if I may use the word was,because it is still here especially outside the dence part of the universe - the rests of the bang. Apparently dark matter exists inside the "bang" only in "lesser" quantity than outside, but the more universe expands the less dence it gets, the more dark matter forces into the universe.The question is if it has a mass and if yes is it bigger than the mass of the universe - mass of all the matter of the"Bang".

[hahajile]

No, before Big Bang were Dark Ages, and

Dark Matter fills 96% of the modern universe.

There are two major candidates for Dark Matter: strangelets and susy-particles (SUperSYmmetric).

The movie however is exaggregating some things.

1. It is not an objective to produce strangelets at LHC

2. One of the major goals is finding Higgs boson, which is also never seen before

3. Energy of collision is only 7 times greater than at RHIC (Fermilab)

[newcome880]

@ hahajile

re 1.: of course not, but it's not 100 % sure they could form

2. yes, the Higgs particle is supposed to give matter its mass / gravity, but it's only a hypothetical particle so far

3. yes, but this may suffice, somewhere could be a breaking point

[Vassitch]

"3. Energy of collision is only 7 times greater than at RHIC (Fermilab)"

5 Gev on RHIC end 14 Tev on LHC

(5 000 000 000 VS 14 000 000 000 000)

[newcome880]

@ Vassitch:

thx for that comment. However, the RHIC reaches up to 250 GeV for protons (google it, can't post URL's). But this is still 28 x less than for the LHC. The most powerful accelerator so far, the Tevatron, reaches energies up to 1 TeV (hahajile meant that one). Anyway, the higher the energy the greater the danger. There could be a critical point just like there is a melting point and a boiling point for substances.

The question is: what scientific value does dark matter hold? If it can't be analyzed, and it holds no value other than simply proving its existence, then there's no reason to create it.

To further ask, how much dark matter is necessary to create an endgame scenario? If two lead atoms can create dark matter, but not enough to properly start the chain reaction, there's no worry. Otherwise, curiosity will kill the cat, so to speak.

Any idea if there's an emergency jettison plan, just in case?

[thriceplowedfield]

i imagined dark matter to be a giant "particle". Big, blobby particles. I wonder why I imagine that?

[newcome880]

dunno what dark matter looks like - haven't seen it yet ;) - and I think I don't want to know/ see it either

[thriceplowedfield]

no, dark matter is the good guy - it's apparently what's holding our galaxy together but unfortunately losing it's power to keep galaxy clusters together as dark energy seems to be increasing the distance between galaxies at ever increasing speeds and is theorized to lead to the big rip. First the galaxies disappear from view, then galaxies are ripped apart.

basically this dark energy is in the process of converting the whole universe into photons.

is dark energy really light? (confused look)

[newcome880]

when I said devil, I meant this allegorically, of course. Dark Matter isn't the devil ;) but you could compare it with that if it eats up Earth. You won't call it the good guy anymore then, would you ? At least you draw the right conclusion about its characteristic of holding galaxies together :)

[thriceplowedfield]

at my current state of unlearnedness on dark matter, my presumption is that it's made of altogether different stuff then a black hole. the only thing i have to go on at the moment is that dark matter is very different then "ordinary" matter, and a black hole is likely ordinary matter, at the very least black holes arise from ordinary matter.

like you though, i'm really cheesed off at this whole LHC.

i'm partly jealous, and mostly horrified and outraged at the hubris of it all.

[evergreencreativeart]

I'm not sure it's the devil that will be encouraged to come thru the LHC. It seems the devil is always tempting and enticing us daily; however, I believe there is concern with the LHC, as far as Physics is concerned, because not even physicists have any of the answers as to if this is 100 percent or not. They honestly don't know themselves if this is safe. We are all being taken for the ride whether we like or not it seems. Shame on them who should know better whether to proceed or not.
