So -this- is what Dyson was spamming me about. They sent a link to some BS video clip of people going "what is that?" and "Cool!" All with not a word or view of the object itself. Apparently they plan to unveil it Oct 15th. Personally, I can't stand these "buzz" type ad campaigns.

Given the wondrousness of my Dyson vacuum, I'm willing to wager that they've got some really creative process here...they -are- masters of vortexes, after all. I'd also guess that it's going to be hella expensive.

This is probably what the Total Perspective Vortex is like.

If you test fire 10 of those things simultaniously could you alter the earths rotation a little bit?


no
to move earth you need to propel something to the opposite direction.. what this thing is capable of doing is causing a relatively tiny vortex in the air above the rocket.. nothing is propelled anywhere(from earth), thus no movement is transferred
it's the same thing as fears of nuclear testing altering earth's orbit (like in that '61 film 'day the earth caught fire' (fun apocalyptic film though))
you would have to jetison a ridiculous amount of rock, or something, to push earth anywhere.. if it just goes boom it doesn't do anything

best chance of this moving earth anywhere would be to tie houndreds of them to the north pole ice sheet (largest untethered mass on earth), and even then the acting mass would be that of the ice
though even the success of that would probably be fairly limited as the rocket would still have to outrun the vortex it created above it

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:

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


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.

I want one of those vortex guns.

Thanks gwiz!   This one is skyrocketing.

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


You imagine wrong.

Your video, Colliding smoke rings produce multiple mini-vortices (11sec), has made it into the Top 15 New Videos listing. Congratulations on your achievement. For your contribution you have been awarded 1 Power Point.

I DIDN'T NOTICE THAT! OMFG OMFG OMFG! DOWNVOTE!!!


Not.
