Couple LHC questions?

Question

is it a vacuum? because if there was no air in there, wouldn't the black hole just evaporate because there is nothing to eat? also, if the collision will create matter from milliseconds after the big bang, wouldn't the black hole not be strong enough to swallow anything because it would've swallowed everything at the beginning?

i'm a little uncomfortable about this project. I don't see how the argument that cosmic rays hit our atmosphere everyday, is an argument. Maybe its different in the atmosphere. The only reason i feel PARTLY safe, is because we've been freaked out about all this stuff before

Answer 1

There are lots of filters, verifications, audits in order to implement a project of this magnitude, there are several governments involved, tests have been made. Do you think that governments would put to work something that can go against their own countries?

Answer 2

You don't know enough about this project to be uncomfortable with it.  Black hole creation is just a theory some have expressed.  Educate yourself about this (not at crazy conspiracy theory websites please)  It's not a black hole factory buddy.

Answer 3

The cosmic ray collisions in the upper atmosphere is exactly the same type of stuff that the LHC produces.  Cosmic rays are atomic nucleons, which the LHC also uses.  Cosmic rays, however, have a lot, and I mean A LOT more energy than the LHC can produce.  The only reason we don't study those instead is because they occur randomly, and uncontrolled.  But to answer the first part, the collider is kept in a near perfect vacuum so that the particles don't collide prematurely.  But the result of the final collision flies away at nearly the speed of light, in which case any black holes would fly through the earth and out of the galaxy, if it didn't evaporate in a trillionth of a second first.

------------------

I don't think I can answer the last question.  I suppose they could put something in orbit to study cosmic rays, but since they don't, there must be a reason.  In the LHC, they know exactly when and where the collision will take place, so that's probably a factor.

Answer 4

A black hole can only be dangerous if it is a certain size.  The black holes they *theoretically* might get are microscopic and their mass would not be great enough to pull anything in.  Consider this: the density of an atomic nucleus is something like 3 x 10^17 Kg/m^3.  That's like the core of a neutron star.  Yet we do not see atomic nuclei sucking up everything around them.  It's the total mass that counts when it comes to gravitational effects.

Without the necessary mass, a micro black hole would immediately disperse.  In these experiments they are using very tiny amounts of matter, so they can't create a black hole more massive than the weight of most atomic nucleii.

Answer 5

I trully dont know the answer to you question I want to know the answer, therefore I will check back to your question.

Interesting question

Answer 6

ah, i love it when someone says they are interested in current physics experiments.

time to read.

time for school.

stop out at your local college and talk to a physics prof.

watch The History Channel (no, wait... that channel is a load of c**p)

take a librarian to lunch.

tell her that her eyes are a very attractive shade of blue...

hey, I think I am getting off the topic.

Answer 7

you hit the nail on the head with yur original statments.

"wouldn't it be much easier and less expensive to watch random cosmic rays, hitting our atmosphere, then to build a very expensive project that takes over 10 years."

err... you cant do this, how would you know when and where its happening!

the main part of the LHC is not the collider, its the huge camera!! this was the biggest and most expensive peace! i mean its seriously massive! you could not get this in the right place and the right time! in the upper atmosphere!

Answer 8

zip over to CosmicLog  and read the inteview with M. Mangano, a theoretical physicist with CERN.....

http://cosmiclog.msnbc.msn.com/archive/2...

sure, there's always a risk.... EVERY safeguard is in place for the things that are expected... but of course, there's a possibility of something UN-expected , as there is with anything mankind wants to do.... I mean, we didn't INTEND for astronauts to die in accidents, now, did we?.....

read the remarks made by 'people' at the bottom of the article.... most of the folks are looking forward to what will be found in these experiments.... but there's always one.... Whiterabbit DID  hit an important point....

"while I doubt they will be shattering any planets, What does his assurances matter? If they rip the earth apart, it isn't like we're going to hold a trial. What is he going to say? "my bad"

think about it..................
