Reminds me of this article where fusion is created by shooting two "smoke rings" of plasma at each other.

AWESOME!!!

That's the beauty of physics: I imagine two galaxies colliding look very similar.

You imagine wrong.

Brilliant little clip! I guess the good stuff can sift at 15 votes...

Adding video to channels (Timeshift) - requested by Deano.

Beautiful.

Stunning.

Looks like a portal opening into another dimension!

holy shit good instincts arv

I want someone to insert the "PAAANG" sound from Episode II's jango fett-bombs.

I want one of those vortex guns.

What's timeshift about this video? That's real speed. I'll give someone the opportunity to prove me wrong first, but then, it's out brohim.

>> ^Mcboinkens:
WHile I understand two galaxies wouldn't look like that, would you care to explain the physcis behind it? There have been no instances that we know of where two galaxies collide head on perfectly like the rings above. I'm assuming it's because galaxies are largely empty space that does not move like smoke?


It's prob because galaxies are hundreds of thousands of light years across, and the incredible gravitational pulls of each galaxy will act on each other long before they physically touch. They won't transfer all their momentum in a radial direction like those smoke rings cuz of the gravity.

That's my bs, but here is a page from the official hubble site with lots of pics of colliding galaxies:
