Which begs the question of how dangerous these experiments are.

The detection of miniature black holes by the Large Hadron Collider could prove the existence of parallel universes and show that the Big Bang did not happen, scientists believe.

The particle accelerator, which will be restarted this week, has already found the Higgs boson – the God Particle – which is thought to give mass to other particles.

Now scientists at Cern in Switzerland believe they might find miniature black holes which would reveal the existence of a parallel universe.

And if the holes are found at a certain energy, it could prove the controversial theory of ‘rainbow gravity’ which suggests that the universe stretches back into time infinitely with no singular point where it started, and no Big Bang.

The theory was postulated to reconcile Einstein’s theory of general relativity – which deals with very large objects, and quantum mechanics – which looks at the tiniest building blocks of the universe. It takes its name from a suggestion that gravity's effect on the cosmos is felt differently by varying wavelengths of light.

The huge amounts of energy needed to make ‘rainbow gravity’ would mean that the early universe was very different. One result would be that if you retrace time backward, the universe gets denser, approaching an infinite density but never quite reaching it.

The effect of rainbow gravity is small for objects like the Earth but it is significant and measurable for black holes. It could be detected by the Large Hadron Collider if it picks up or creates black holes within the accelerator.

It'd need to be at incredibly large energy levels to be a threat.  It'd be cool though, none of us would have a clue it happened.  ;)

Okay, whew, that's good that they can't accidentally destroy our world with little black holes...

in several multiverses, they did/do destroy the world...just not this multiverse...

Well then thank goodness we're living in this one!

... yeah, but now I can't go get my National Park passport stamped in the other ones!

National Park passport not good in other multiverses?
