Apparently, planets sometimes just explode.

If he's correct, where Mars is, there was another planet earth size,
which had Mars as a moon until it exploded.


Something the size of earth could not have something the size of mars
as its moon. Perhaps something about five times the size of Earth
could, but certainly nothing Earth sized.

Couldn't two objects of roughly equal size orbit each other?

Where do you get the 5 times figure?

I'll admit to not being really up on what makes a stable orbit in our
solar system so I'm really curious on elaboration.

I read somewhere that the earth itself is inexplicably expanding in
size.

Now to me that's not a surprise.

One day then, if the theory is correct, the earth may simply, almost
completely out of the blue, explode.

Perhaps Earth's volcanic activity will prevent it from ever exploding.
I surely hope that's the case.

Well I think that part of the theory is that stars explode as well.

I think part of the idea is that movement through space actually heats
up large bodies, and is part of the energy source for stars like our
Sun.

That is, fusion isn't providing all of the Sun's energy, and if the
balance isn't preserved, our sun itself might one day, just explode.

Um, maybe humanity should SERIOUSLY and diligently work at
interstellar travel.
