The world needs a new source of energy, an unspillable source.

Do you think the nuclear fission reactor in France will implode on itself releasing a man-made star on earth?

I hear that they are building a nuclear fission reactor in France. The benefits to our society would be immence, but if it backfires could it possibly destroy our exhistance?
I mean if it works we WILL have discovered a endless fuel source and our reaches will be greater than ever.
But technically couldn’t it implode on itself destroying the facility and possibly the world?
Ok sorry I mean fusion not fission
