What would happen if the worlds crashed together?

Answer 1

If by 'worlds' you mean planets, then they have in the past. The Earth and the other planets were formed by crashing into and clumping up into debris in their orbit. These orbiting pieces then formed together into large bodies as planets.

Answer 2

Well, that would depend on which worlds and if one of them was the Earth.
If another planet collided with the Earth, its likely both would be destroyed (at least all life on them would be eradicated). If not completely destroyed, one or both of the planets could:
- be completely ejected from the solar system
- be thrown into wildly eccentric orbits that could intersect with another planet
- be thrown into an orbit that would take it into the sun
- be thrown into an orbit that would take it far from the sun

Any of these would not be a good day for humans.

Answer 3

Depends on the speed and collision angle and matter.
Let's say a hard life planet was Planet A and a terrestial planet was planet B. A gas planet of same size called Planet C, and a hollow Planet called Planet D

A(high speed collision against)>B= B out of orbit and half destroyed, A as well 1/2 destroyed (Same if opposite)

D>C Material bildup at C core (Same if opp. or others)

A>D= D almost thrown and completely shattered. Half devestaion on A.

So effects depend on the factors of planets nd their main gravity force,

Answer 4

Worlds do crash together all the time in space. You can see pictures of it happening at the Hubblesite dot org web site. Go there and click on Gallery. Take some time looking at the vastness of space through the eye of our largest telescope in space.

Answer 5

What would happen if you actually acquired some intelligence and asked a more thoughtful complex question?

"Oh, gee. I wonder what would happen if two planets collided?"

"Ummmm, would they bounce off of each other? Noooo."

But, you have to have the OBVIOUS explained to you. That's very bright, Einstein.
