argumentA line of reasoning from premises to a conclusion. Like a claim, it belongs to no one who makes it.constitution →

Cosmic-ray bound

againstThis argument, if it holds, weighs against the claim.constitution →A high-energy particle collision could trigger the universe's vacuum to decay into a more stable state.

The argument

Because linked claim, and because collisions of comparable and far greater energy have occurred throughout the observable universe for billions of years while a vacuum-decay bubble expanding at nearly the speed of light from any of them would already have reached us, collisions at accelerator energies cannot carry any appreciable chance of triggering vacuum decay.

Does it work?

Not yet evaluated.

Premises

UnassessedNo current assessment. Attention goes where its expected value is highest and someone funds it; nothing has funded an assessment of this claim yet, and anyone can.constitution →Cosmic rays with energies exceeding LHC collision energies have struck Earth for billions of years without causing catastrophe.

The inference goes through: since a vacuum-decay bubble expands at nearly light speed, our continued existence after billions of years of far more energetic natural collisions bounds the per-collision probability at an extraordinarily low level. The argument rests almost entirely on linked claim, an observational premise no informed party disputes. Its one known refinement, that cosmic rays might be inefficient bubble triggers, weakens the bound on metastability itself but not the conclusion that collisions cannot trigger decay, since the same inefficiency applies with greater force to accelerator collisions.
