Gravity Waves
Sort:
And they DID see them! It was announced today.
They saw 2 frigging black holes colliding and forming a super black hole, burning the energy equivalent of 3 suns in 0,2 seconds.
(Or I guess more energy, the 3 suns was just the gravitatonal waves.)
This is what it looks like when black holes collide
...Anyway
I'm wondering what else you can see with the LIGO?
Is it just enourmous events, or can you see smaller stuff happening closer to us?
Wondering if it will be possible to find the missing planet (they think there's an extra planet, but they can't find it) or map out the asteroids and such?
Maybe you can also see dark matter with the LIGO?
And then there's some more Big Bang stuff we can see now.
Black holes are just the result of the systems that are in orbit around each other aren't they? The forces that result from the "right-hand-rule" in physics I mean. I thought that's why they emit the perpendicular gamma rays at their centers.
I looked it up on wiki and it seems they can form from
1: Old stars collapsing
2: Some were already formed in the Big Bang (All the mass was packed in a smaller space at the time)
3: High energy collisions of things with a lot of mass (contested if this ever happens)
I thought black holes were the things golf balls fall into in the 18th hole at putt putt mini golf.
So what travels faster, lightwaves or gravity waves?
Perhaps lightwaves.
No one has answered this already? Ok, I'll take a stab at it though don't expect anything other than what you can easily find on Bing. Gravity waves are ripples in space times, likes waves on the surface of a pond after a rock has been thrown in. Gravity waves move at the speed of light. Gravity bends or curves space and time, just like a rock that is heavy enough on a rubber sheet will bend the rubber sheet. Sometimes, the rock can produce waves on the rubber sheet, and those waves are like gravity waves. I hope this was satisfactory. :)

They move at the same speed, c, in a vacuum. The first measurements of gravitational waves have also provided a little support for this, because the observations of the black hole merger were detected at slightly different times at two detectors. This was consistent with the waves moving at the speed of light and assuming that was their speed provided some information on the direction the waves had come from. With three detectors, the position could be pinned down, and with multiple detectors the speed of the waves could be checked quite precisely.
[Note light travels at a slower speed in materials, eg glass. This is because it interacts much more strongly with the constituents of the material].
Apparently some Americans prooved something called gravity waves exist, and this is quite a big deal.
Any physics people here that know what they are and why they are such a big deal?
