Can you explain? The LHC produces energies that are less than what the earth has been bombarded with from cosmic sources since time immemorial.
Also what exactly is a "black hole chain reaction"? How are these black holes possible exactly? The energy involved in a single proton are not enough for a stable microscopic black hole to form. This is presuming it even CAN form (its at best a hypothesis) given our understanding of gravity.

Crazy high unpredicted outputs happened before (google operation Castle Bravo) so is not totally insane to consider a worst case scenario. We don't have exactly a kickass theory (that's why we built the LHC in the fisrt place) and all we can talk (predict) about black holes formation is merely hypotetical. I don't think we are in danger with this experiments other than draining taxpayers money at virtually zero ROI
- akiselev 12y agoWe do have a kickass theory, two in fact: the standard model and general relativity. We still have a lot to learn about both (which is why we built the LHC) but to suggest that high energy particles with energies and densities many, many orders of magnitude smaller than of our sun can create a black hole (which itself is an order of magnitude too small to collapse into a black hole) requires some serious mental gymnastics falling well outside of observed physics.
- sebastianconcpt 12y agoWe have a multiparadigmatic-conflicting set of models to try to explain (parts of) the observable Universe. If a theory can't explain nor predict origin of Black Holes, Dark Matter and say what Gravity actually is and why happens, then that doesn't qualify as Kickass in my book. Show me teleportation and controllable antigravity and we can talk kickass again.
- mitchty 12y agoExactly, the energy of one particle is the same as how much a mosquito puts out if I remember correctly. The black holes formed from this, and this is presuming its possible to do so mind, wouldn't have enough energy to pull in other matter. Could our theories be wrong here? Sure, but worrying about this is just like the scientists worried we would ignite our atmosphere with nuclear testing. That is, its unlikely at best and needless worry in general.
- Retra 12y agoBlack holes are not formed by lots of energy, but by high energy density, so your mosquito comparison is not very useful unless you've got some other measure to support it.
