Will our universe collide with another ?

Its a scenario of apocalyptic proportions but in a theory that is rising in popularity among physicists our universe may not only have the potential to collide with another but may have already done so in the distant past.
Relaxing on an idyllic beach on Grand Cayman Island in the Caribbean, Anthony Aguirre vividly describes the worst natural disaster he can imagine. It is, in fact, probably the worst natural disaster that anyone could imagine. An asteroid impact would be small potatoes compared with this kind of event: a catastrophic encounter with an entire other universe.

well where would the the universe come from? its hard to question but if univereses are seperate id assume, they would be so by some sort of interdeimensional type of phenomenom. as in co exist simultaneously with our own. do you think that if we reached the boundries of our universe we could physically see the one sideing with us. maybe theres some type of membrane like structure surrounding each universe hindering us veiwing other universes. seriously things like this i could question for hours. fascinating

Wait a minute.... Ummm...... These "scientists" don't know that it is happening right now? What in the living Hell is wrong with these minimally educated, closed ended biological cul-de-sac, short chain molecule, misfit, unstable mutations!!! Has any of these simpletons heard of the Sagittarius Dwarf Galaxy and the Canis Major Dwarf Galaxy? Our galaxy has been in an on going collision with these guys for a very long time! The Milky Way is eating these up right now! There was another.... ummm..... Crap I can't find the galaxy that the Milky Way has already chewed apart! But there is still remne... [More]

The Milky Way is eating these up right now! Maybe some one should tell these "scientists" about "Galaxy Caniballism"! I don't even have a degree and I know more than these retards! Thats REALLY sad! And yet again. Someone who cannot read and understand the simplist terminology. Galaxy (is not equal to) Universe.

OK guys, I'll set my alarm clock to 1.5 million years from now... to be prepared.

And what do we have as an end product of this collision? Thanks B??? Well, behaviour, we have no idea. In fact, what is being discussed is a theoretical construct, and nothing more. The fact is, there is only one known universe. Others have never been detected in the slightest. Discussion of them is theoretical at best...interesting thought experiments. We don't know that other universes exist, so we really can't make any projections about them at all, let alone what might happen if we in our universe were to collide with another.

Pfff..such a open question. Will it rain in two weeks on monday? Perhaps. We can collect some data and speculate, but needless to say the meteo service has been wrong several times also. There's no conclusive answer yet, and I'm guessing it might take a while to get one.

There's no conclusive answer yet, and I'm guessing it might take a while to get one. Yes, I suspect a little while...

Well, according to Murphy, it WILL happen.
