what would happen if another universe merged with ours?

Question

lets say we live in a multiverse. what would happen if another univers merged with us, like two bubbles merging together.

Answer 1

they would get peanut butter on our chocolate

Answer 2

I guess I am just a stickler for words being correct, and maybe I don't know everything that is to be known...

But, I was under the impression that the "Universe" was everything out there beyond our Solar System, which would of course include this other entity you call "another universe."

Now if another Solar System was to merge with ours we would be in for a tremendous period of torment here on Earth. That suggestion means that another Sun has moved in and is competing for space with our Sun. Orbits of planets would begin to change under the influence of this new Sun, and days, nights, and seasons would just go all whacko. Heating of the Earth's surface would be changed in a manner that could do nothing but harm our delicate situation and bring us more unnecessary heat. We already have some indications of what to much heat can do to the Earth's population of creatures. Ice Caps melt. Lowlands are flooded.
Species are drowned with frequency. Heat dries up water and large deserts are formed where once stood majestic forests. More than likely we would see the end of the human race.

Answer 3

Gravitational pull from the converging Stars and Planets from the merging universes would cause destuction of many of the bodies that make up both of the universes, leaving you with a single universe with the surviving but altered solar systems.

Answer 4

i'd say there's a stable possibility that it would finally end up changing some regulations of physics in our universe, which might bring about our instant deaths. If the regulations of the different universe take place to be precisely comparable to those in our universe, then there would be no subject moving mass back and forth between the universes. (of direction, i'd in all possibility be the fool who jumps by way of the portal and finally ends up with six hands and a 2d head in my abdomen)

Answer 5

Depends on the dimensionality of that universe. Even now, multiple universes may be interpenetrating our universe of three dimensions. If you meant a three dimensional universe like ours trying to merge with our universe, all the existing structures of this universe will be destroyed.

Answer 6

Chances are that any other universe wouldn't have the same laws of physics as our universe. For example, if the other universe contained mostly anti-matter (..ours contains mostly 'normal' matter..) then absolute devastation would result from such a merger.

Answer 7

That would instantly prove many theories wrong ;)
I guess nothing much will happen, or maybe, the moment they collide, they will create another universe in another dimension.
...Something we will never know.

Answer 8

who can say we only know about one universe, there is no real answer the this question because there are no physics to support it, anything would be just speculation.

Answer 9

Current theories say that if there are other universes, we'll never know it.
