Report: Planets will collide in 5 billion years - 0 views
-
Mercury, Mars, Venus and Earth to smash into each other, either one at a time or all at once
-
by the end of that same 5 billion years the sun will have burned up its hydrogen and in a cooler state will inflate itself
-
the great "gas giants" of the outer solar system - Jupiter, Saturn, Uranus and Neptune - are extremely stable in their orbits, so they could remain where they are for a much longer time
-
Interesting, but obviously something is wrong. How the big giants can remain still if the inner planets and the sun vanish at the same time !
