Obviously, the 'big bang' can't be re-created without compressing the whole universe into a single point, which, as far as I'm aware, the LHC isn't capable of doing, but why is Stephen Hawking issueing these warnings?
Obviously for you and a handful of people.... but for the average Joe the info is credible: even Hawking said so therefore it must be true...
And this is all because of the lack of objective journalism on the internet, because in order to survive those sites rely on click bait articles and/or sensational articles.

who can tell we aren't already compressed in a tiny point with the whole universe? if you compress your universe, you compress your reference... do you compress the universe if you compress your reference?
unless there was a way of opening an instant breach between two places of the universe (wormhole like) any attempt at traveling at any speed is to never see home again, so distance or time should not even be an issue as you are leaving to start from scratch in another time and another place whatever the reason or goal anyway...
what would occur though is that you could see retarded travelers come out of the sky of your new homeland and, being returned to a relative stone age, see them as gods or aliens...
I personally believe that even if there is an original event, this is still out of our perception horizon and what we perceive as a potential big bang is actually the rails joining in the horizon and the kid asking himself if the train will fall off the railway
there are good starting points for science fiction novels there...
...but why is Stephen Hawking issueing these warnings?
The energy required (as far as Hawking says) is 100 billion GeV, which is more than a million times larger than what the LHC is capable of. So it is a warning to physicists far in the future. LHC type of collision energies are quite common in nature. Hundreds of them occur every day on earth by cosmic rays, which implies a lot more of them in the milky way or the rest of the universe. We'd be long gone if LHC collisions wouldn't be safe.

Are you suggesting it's possible that a previous civilization could have caused the big bang by constructing a large hadron collider that was too large?
Hawking suggests an instability of the Higgs field. It is quite different from a big bang and doesn't create a new universe but will destroy everything in the present one.

Yeah, I've seen this hypothesis. It is also possible that our Universe was generated by a quantum vacuum fluctuation in much the same way as the ekpyrotic hypothesis suggests. This also explains how the fine structure constant, nuclear forces and other fundamentals are "fine tuned" because we would not exist if they were different. However in this case silicon might form long chains instead of carbon and life might be based on this. There are probably lots of combinations that can generate a life-sustaining Universe.
