A long time ago, CERN denied the possibility of creating a mini black hole at the LHC.

Nowadays what is CERN's opinion on this?

Are mini black holes theoretically possible?

Sounds weird. But perhaps weirder is that it's not really a mystery at all. We pretty much know this happened because we can actually make bits of the universe do this. We can create energies needed to produce the electroweak states in the Large Hadron Collider. Yep, we can simulate the instant just after the Big Bang. Our theories look really good to that point. But once you get to a crazy 10^29 Kelvin at an age of around 10^-38 seconds, it's expected that this electroweak force and the strong nuclear force-- that's the force that holds atomic nuclei together-- also become unified into one force.

There are a lot of ideas of how this might happen. And we call these grand unified theories, except they aren't theories in the same sense as relativity or evolution because we don't know which, if any, are actually correct. The problem here is that we can't test them yet. We need to produce energies a trillion times larger than is possible with the Large Hadron Collider. Nothing we could build on the surface of the Earth could do this. Perhaps that's for the best. So this is still a huge unknown.We do think that we can describe gravity and the shape of space time at these densities and temperatures. But we can't confidently describe this stuff that the universe contained, the weird state of matter that far back.
