We should have never shutdown the one in Texas...

Clinton did that in Waxahatchi when it was half built-stupid decision, another stupid decision.

We should have never shutdown the one in Texas... Mostly because if it had created a mini black hole that destroyed 10,000 square miles of Texas, no one would have noticed. :)

I guess if or when they produce a black hole or another big bang it should take just a blink of the eye and we will all be toast.

The LHC can supposedly produce collisions with energy of around 7x10^12 eV. The hightest ultra-high energy cosmic rays, however, are around 3x10^20 eV. That gives cosmic rays, which have been hitting the earth for billions of years, about 40 billion times the energy that the LHC can produce. So far, no earth-gobbling black holes. Another thing, collisions at very near the speed of light produce secondary particles also travelling near the speed of light. So any black holes created as a result would fly through the earth and into space in less than a second. Thirdly, there Hawking radiation. A black hole of such low mass would evaporate in a nano-second at most.

Theorhetically mini black holes are produced naturally all the time but they dissipate in nanoseconds. As I understand it, black holes require a certain ammount of mass for them to be sustained.

Another example of science playing around with nature and not knowing the after effects.

black holes require a certain ammount of mass for them to be sustained.Yeah, but is that mass a rock, a planet, or does it require a whole galaxy? It's important to know these things.

Who knows? It may open a doorway to a parallel universe.

That’s science and its how we ended up with nuclear reactors.

That’s because of Hawking radiation. The smaller a black hole is, the quicker it evaporates. The rate of evaporation becomes exponential with mass loss, and anything lighter than about a mountain will not gain further mass because the radiation pressure will exceed its gravity. But at that point, it won’t last long anyway. Hawking theorized all this using generally-accepted physics.

We need to be very careful when dealing with the fundemental forces of the universe.

Thanx.
Nice clear explanation.

We need to calculate whether any “side effects” may happen during these experiements.

Look at the bright side - the collider may save us from global warming!

If it opens a door to another universe, it solves all our problems...just send all liberals and democrats there. But we better know how to shut that doorway first..or they will just stream back in, without taxes to pay for their pet projects they’d be toast as a total population..
To: goat granny
Well, we would need to find a parallel Earth where life never took hold to stick them there.

How unusual. A little wisdom on a science thread for a change.
Thank you very much.
