quote:I wonder if it would cause massive tectonic activity so that the core of each planet would be drawn towards the point of contact
quote:Originally posted by Roy PIf it were possible for two planets of the same size to gently come together, like a double Earth, say, what would the conditions on them be like -- specifically near the point of contact?Roy P

quote:Originally posted by ROBERTquote:Originally posted by tony6789ummm i don'tnderstandNEVER! underestimate youthPlanet Earth is mostly liquid.Two Earth like planets close together would coalesce like two drops of water.
quote:Originally posted by science_guyIf two gravitational forces of even strength from two planets would not double the gravity in between the two "earths", what would happen, because they are on opposite sides, is they would cancel.
quote:Originally posted by Roy PYes. This is exactly what I assumed.
quote: Dammit. You scientists just have to ruin everything don't you
quote: OK. What if the two earths had a crust thick enough not to break like an eggshell, and only coalesced a little bit? It would be fun near the contact area wouldn't it!
quote:Yes, it may be fun at the contact area, but the combined forces of gravity may be unstable enough to pull you apart. Although the two forces cancel eachother, they are still acting on your body.
