Imagine what mass the size of a star does to the fabric of space-time. Light, from behind the sun, is bent around the sun. All these planets are trapped in the sun's gravity, and this gravity extends beyond the planets. If a planet the size of the sun (never mind that fact that a planet cannot be that size) were to fly by the Earth, long before the planet would get close to the Earth, tidal forces would stretch the Earth toward the the planet. Then, as it passed, the Earth would return to it's normal shape. As the planet moved on, again the Earth would be stretched. These forces would melt the Earth, and fling the molten material after the planet as it passed. POP!

or is there a limit where it would collaps the universe around it?also how come superman didnt melt when he lifted the core of a neutron star?
There is a limit of size fora planet, but I do not know what it is.
I cannot answer any questions about superman. He is beyond my ability to comprehend. Just the fact that when some bad guy is shooting at superman, and the bullies are bouncing off his chest, he then ducks when the gun is thrown at him, baffles me.

There isn't a limit. Objects that are really really massive will usually either collapse, becoming a black hole, or tear themselves apart from the heat their gravity creates. As far as I know black holes can have any mass and stars can get to mindbogglingly huge sizes.

Because as a Kryptonian he is protected by a solar powered bio-energetic forcefield. Being so close to the core of the star must have temporarily supercharged it.

[B]They wouldn´t orbit each other because the mass is too little. They would just hang there in space, well except for the human who would blow up due to excess internal pressure.
Won't happen. The human body can withstand the minus 1 bar atmospheric pressure difference easily. There is of course the eventually fatal Caisson disease that will occur when suddenly exposed to low pressure, but it won't make you explode Total Recall style.
Every bit of matter has a gravitational effect on all other matter around it, but in the proximity of far more massive objects like stars or planets the effect is almost nonexistent.

No, the earth would be pulled along with them.
I remember a projection of a hypothetical collision with a Moon sized object where scientists showed the Earth beginning to crumble before even making actual contact with the object.
Can anyone explain the forces at work in that scenario? I recall it being related to gravity.

Originally posted by Omega VisionIt was probably tidal forces: gravity pulling on the nearer side of a celestial body more powerfully than it's pulling on the further side. It is suspected, eg, that this is what caused the asteroid belt: Jupiter's gravitational field tore a planet/moon too close to it apart. Some of Jupiter's intact moons are still affected by tidal forces: the gravitational pulling and stretching of the moons heats their interior. Some scientists think this is why Europa may have a vast liquid-water ocean beneath its icy surface.
