Fair call. By Earth V.2 I was just meaning a planet with water and a similar atmosphere to our own. Mars actually looks as though there was liquid movent upon the surface at some stage evidenced by the Vallis Marineris (spelling) and also geological activity (Olympus Mons) One feature it does...

Of course it would be, why hadn't I thought of that? Thanks for the links!

This is very interesting, wish I knew more about quantum mechanics.

So we'll be capturing using audio waves and then interpreting? Or would the dust interfere with audio too?

Okay, so it's looking as though quasars aren't a one off, they seem to depend on availability of matter, dense and abundant matter being the trigger?

Thank you everyone for helping me attempt to get my head around this.

Ah okay. You've been very informative today, thanks for all your help Drakkith. So a dwarf planet, something with about the mass of pluto or mercury? It sounds like the impact Earth was involved in during it's evolution. I wonder if Mars would be Earth V.2 If it had undergone a similar impact.

Actually, thinking about this, I'm guessing it depends on the nature of the matter being compressed.

If a sugar cube size piece of neutron star weighs as much as every vehicle in U.S.A, and H2 in the core of Jupiter has been compressed to a metalic version of itself, what then is the limit of compression? Can matter be compressed further than that of a neutron star?

Ah okay, It's making sense now.

Using the balloon analogy for an expanding universe, how then is it possible for galaxies to collide? Is the gravitational pull of a galaxy enough to influence another? Do dark matter and dark energy have an effect on expansion? Sorry, so many questions >.<

Okay, so all elements from the periodic table up to and including iron are created within the cores of large stars, how are the heavier elements assembled if the star explodes at the production of iron?

I'll put the kettle on.

If it takes 4.5 billion years for the collision, and another 4 billion to merge, that's 8.5 billion years, our sun would be a white dwarf by then, and my rent overdue XD

Thanks Drakkith. I wonder then if the collision of the Milky Way and Andromeda would create this scenario.
