Nine Days, End of the World?

no where in Einsteins theory does it state that a large amount of mass is required. It references a star exhausting its fuels with the mass of 3 times that of the sun causing it to not be able to support itself against its gravitational inward pull. This mass is used just as an example though.

I am no expert on the topic but here goes.

Not all stars turn into black holes only super massive ones that exhaust their fuel that are 3x the size of our sun as you stated. The rest turn into dwarfs of some type. They still have a lot of mass when compared to their volume(heavier than they appear) they just do not have enough mass to cause light to turn on itself.

Therefore I conclude that a lot of mass is required to create a black hole. The scientists may say that black holes will be created from the experiments but they only have theory and equation data to go by, they don't really know. Besides, a black hole can not be observed directly so how will the scientists know for sure if one lasting micro seconds or less was ever there?

Einstein's equations were wrong about a non expanding universe. Hawking's equations were wrong about traveling faster than light to roll back time so then it may be possible that there won't be any tiny unobservable black holes at CERN. Just a possibility.

Why does everyone go by Einsteins theorys still?

I bring up Einstein because his theories are still relevant today and to my knowledge no one has proven him wrong on anything after 1955. RIP.

If you had the entire mass of the Sun and if you could shrink it down to a 3 km ball, then you'd have a black hole. Obviously, the LHC cannot do that (for starters, the LHC weighs a lot less than the Sun).

IF the LHC has enough energy to achieve this condition, then this condition must already exist in the universe, since there are cosmic rays with more energy than the LHC. With the density of cosmic rays that exist, it is certain that collisions of cosmic ray particles can pack more energy than the LHC. This means that the universe would have had a very large number of these energy black-holes.

Therefore, the universe still exists.

So to summon it up, Either black holes are not dangerous (meaning: they evaporate before doing anything else) or they don't exist (in which case the LHC will not be able to produce them)

You guys dont understand that theres not just one type of black hole, the one your referring to that requires 3 times the mass of the sun are called "Stellar-mass black holes". Like i said earlier, the theory was just used as an example. (And if you must refer to Einstein, he himself never even believed in the existence of black holes) The ones that are thought that may be produced by the LHC are called "Micro black holes"

Micro black holes (also mini black holes) have masses much less than that of a star. At these sizes the effects of quantum mechanics are expected to come into play. There is no known mechanism for them to form via normal processes of stellar evolution, but certain inflationary scenarios predicted their production during the early stages of the evolution of the universe. According to some theories of quantum gravity they may also be produced in the highly energetic reaction produced by cosmic rays hitting the atmosphere or even in particle accelerators such as the Large Hadron Collider. The theory of Hawking radiation predicts that such black holes will evaporate in bright flashes of gamma radiation. NASA's GLAST satellite, to be launched in 2008, will search for such flashes as one of its scientific objectives.

Well thanks for the lesson on astrophysics. I told you I was non qualified.

Anyhow I had heard of mini black holes but do not understand how they work I just figured that they had compressed themselves to the size of a pinhead and perhaps have an event horizon the size of a volley ball I don't know I am guessing there. Ultimately they would distort gravity enough to suck up everything in site.

I have heard Hawking's theory that black holed evaporate. I missed the mini part. The way I understood it was that one atom would escape the schwarzschild radius until eventually there weren't enough to affect a change in gravity.

I have not read a good book on quantum mechanics in a long time and the field is constantly changing.

So they are launching another Gamma Ray Observatory? What was wrong with this one?:

uhhh, the one your referring to has been de-orbited since 2000 it says.

GLAST is a powerful space observatory that will explore the most extreme environments in the Universe, where nature harnesses energies far beyond anything possible on Earth. It will search for signs of new laws of physics and what composes the mysterious dark matter, explain how black holes accelerate immense jets of material to nearly light speed, and help crack the mysteries of the stupendously powerful explosions known as gamma-ray bursts.

Yea it was up for almost 10 years. That is a long time to watch ray bursts.

lol

I meant to remove that skeptical, uninformed post of mine a while ago.

Rox Fox if your actually worried, take some time to read this.

Recently I tried to re-capture my atomic knowledge.

All I really know about is ionizing. Relly just in neon lights.

The voltage on the neon atom might break it which releases two electrons. Those two electrons smash into other neon atoms which creates energy which produces light.

I thought yall were stupid till i read this on Engadget.

4.4 billion huh? Couldn't that money of been used for something more useful like removing pollutants out of the air, or finding some way to stop global warming?

Pollutants, Yes. Global Warming, No, Its a natural thing that has happened since the forming of the earth, yes we have made it probably ten times worst but there is no way to stop it.

Anyways yes I do think 5 billion dollars should have been put to something else though.

Wait, hasn't it happened already?

Wait, hasn't it happened already?

Um... uh oh... I think... TOMORROW!!!!!!!!!!!!

*runz*

In all seriousness though, I'm very interested in the results of the test. I don't think it proposes anything dangerous to the future of mankind. I'll be even more interested to see how many scientists are cast to the side for believing that it would have before they fire it up lol.

They claim the experiment violates the right to life under the European Convention of Human Rights. However, the case at the European Court of Human Rights is not expected to delay the switch on, scheduled for Wednesday of next week.

Since the story was posted on the 1st this Wednesday coming up will be the day.
