Lord of the Rings

I know it's not Mars but I just cannot help getting excited about the greatest physics experimentof all time. Roll on Big Bang day 10th Sept everything seems to be on target and going to plan. We shall have to create new numbers to cope with this one they will acheive 99.9999991% of light speed in an environment just a fraction above absolute zero. WOW!

If they accidentally create a black hole, how much notice would we have of our impending doom?

Seconds?

Minutes?

Hours?

Days?

I think the answer is the same as the time period between when Gabriel blows the last trumpet and our souls get swept up in the rapture.

Nice of you to assume we are all going to get swept up in rapture!

It's fortunate that physics is not the field of IT, with all the vagaries of wondrous 'collapsing' inferno's underway region to region. Physics could be better compared to the science of nutrition, and the culinary arts.
The real reason for these experiments is the sci-fi 'replicator' microwave oven sized devices we see on television, and the common, 'gotta-have-one' impulse in most of us.
What will all this lead to? Will we find a method as broad and enlightening as the process of photography, a process which has a hundred and fifty years of historical development? An expanding vision of reality as it is, and not as we think about it.

Hey.......meebee THAT'S why we can't find any advanced civilizations beyond our solar system. They all tried the experiment and were sucked into the black hole they created. Hmmmmmmm....

Well John, it's not that crazy an idea.

Sir Martyn Rees, Astronomer Royal,thinks much the same.

There may be any number of ways of accidentally creating black holes that you don't find out about until it's too late. When you factor in also the possibility of unintended plagues, mass crop failure, mega meteor impacts, robot takeover, and species-suicide by mad terrorist then the odds don't look quite so good for human-like life forms!

Hi Field,

They do hope to create a black hole but it will be minute and will only last a nano second. This is true sub atomic stuff.

2 Days and counting !

This is going to a great.

KPM,

great that you point that out: a hole with mass 10^(-22) kg. I can survive it, if it hits me straight on the head

Do you think Dark Matter consists of microscopic Black Holes?

These are still a mystery as to how or why they form I have always felt they are the same as whirlpools in the sea i.e. there are differing energy currents whizzing past one and other in space and create this concentrated gravity "spot" I am sure they start off small and if the conditions are right and enough matter is consumed then crushed to a billionth of its original mass then it will grow and get stronger. I heard you have to get quite close to one to get pulled in, maybe it's a wormhole archway bending space time light matter and everything else, we may discover tomorrow and the coming months. Or will the emergency bells ring with a call to say "for God sake quick! switch it off!"

extrasense, I've wondered if the "dark matter" is actually black holes. Spiral galaxies seem to be swirling onto something.

Well we should be firing the first beams by now and wow we are all still here boy are there some nonsense scientists out there!

Hi John

As the Universe expands the void is filled by dark matter which would mean black holes everywhere and a big crunch as opposed to big chill. From the various orbiting telescopes and following Einsteins lensing theory it would seem there are invisible forces bending light in areas between galactic collisions this area of gravity is strong and suggests dark matter is present but not a black hole i.e. no Event Horizon. Why we cannot see Dark Matter remains to be discovered however I don't think it is stopping light escaping LHC may help solve the mystery.

'Dark Matter'...a form of early gravity-molds unbounded because of age and space or in the making...my contention.

Interesting and possible although some think it may have been from collisions that seperated the matter into dark and visible.

One guess might be that Dark Matter is a gas of tiny Black Holes
