Note that during that it is very rare for things to physically collide. Also the temp comparatives I hear about were from Mars (took 2 semesters of astronomy in collage and 1 in high school).

Yeah the planets don't physically collide. What happens is when the two galaxies are reaching each other, it's more of a swerving motion. They call it a collision of the galaxies for some reason
