What would happen if you were to release the energies of the big bang in our universe a second time?

Question

Would it just wipe out everything, or would something else occur?

Answer 1

What would happen if you were to release the energies of the big bang in our universe a second time?

Have a look at this standard history of the universe,

History of the Universe - gravitational waves are hypothesized to arise from cosmic inflation, an expansion just after the Big Bang

Our universe is now at the far right. Note the beginning at far left where all the energy is concentrated in the inflation period.

If you introduce something like that inflation discontinuity at the far left, in our current universe on the far right, it will eat it up as a black hole attracts all the surrounding matter. It will be a very strong gravitational well. How fast everything would disappear for us is dependent on where this materializes. If next to us, immediately. If some light years away, it will take some years.
