On Wednesday night, two opposing beams of protons were steered into each other at the four collision points spaced around the LHC's tunnel.

Good for them, so long as they don't cross the beams and reach total protonic reversal.
We've got enough problems.

Dr. Egon Spengler: There's something very important I forgot to tell you.
Dr. Peter Venkman: What?
Dr. Egon Spengler: Don't cross the streams.
Dr. Peter Venkman: Why?
Dr. Egon Spengler: It would be bad.
Dr. Peter Venkman: I'm fuzzy on the whole good/bad thing. What do you mean, "bad"?
Dr. Egon Spengler: Try to imagine all life as you know it stopping instantaneously and every molecule in your body exploding at the speed of light.
Dr Ray Stantz: Total protonic reversal.
Dr. Peter Venkman: Right. That's bad. Okay. All right. Important safety tip. Thanks, Egon.

Or you could get an alternate universe where the Berenstein Bears somehow became the Berenstain Bears.

Yes, this is a real discussion on the internet, not a well-known one, but it's out there. http://woodbetweenworlds.blogspot.com/2012/08/the-berenstein-bears-we-are-living-in.html
