Say Anything: Milky Way To Collide With Andromeda Galaxy!!!

    And just think, all this destruction is caused by people who use aerosol underarm deodorant... Oops, i'm showing my age aren't i? I forget -- it's not underarm deodorant users anymore, it's people driving SUV's. They're going to kill us all!!!!

    While some think this is Karl Rove in action, it's actually Dick Cheney. Halliburont will get the contract to clean up the galaxy after the collision.
  • Steve L. · 4 years ago
    Or Halliburton even.

    I thought the sun was going to go Nova in about 4 million years.

    Somebody tell Algore that a Nova is not always a car. With how well his TV network is doing it's probably what he's driving.

    Well, the sun expands to fill our orbit before colapsing into a white dwarf... I don't think it goes nova, though...
  • The Whistler · 4 years ago
    Ummm expanding to fill our orbit is going NOVA.

    A supernova is when it blows up.
  • Seth Yantiss · 4 years ago
    Ah... I had thought that "Nova" was a blast or mass ejection of solar material that didn't stop moving. I can see I was wrong.

    nova -
    a star that ejects some of its material in the form of a cloud and become more luminous in the process


    Oddly, the definition for "Supernova" is the same...

    supernova
    a star that explodes and becomes extremely luminous in the process

    I think we have to define short lived when it comes to sellar evolution.

    I would imagine the Nova period lasts a good number of years.

    If I recall correctly what'll happen is that the Sun will eventually run out of hydrogen to fuse into helium. The sun begins to collapse under it's own weight without the energy of fusion to counter gravity.

    When the sun collapses to a certain point the pressure grows until it sets off the helium to fuse with itself (creating lithium?). This fusion is very energetic and it will cause the sun to expand out beyond the Earths orbit. That could be bad for us.

    I just wanted to show I knew something about it since I committed such a boneheaded million-billion what's the difference mistake.

    The Whistler:

    Actually a nova is a sudden, short-lived brightening of a star, usually associated with the ejection of of material. Another type of nova is when a small dense star that is part of a binary pair "swallows" a clump of matter from its companion star (causing a very large explosion).

    A supernova is just a nova where most of the material of the star gets ejected.

    The Whistler said, I thought the sun was going to go Nova in about 4 million years.

    Make that billion.

    I'd hate to see the traffic jam trying to escape that disaster.
