This time it seems they nailed it for real: gravitational waves

If true this is one of the very real and most maximum biggies in the history of science.

"We found a beautiful signature from of the merger of two black holes and it agrees exactly - fantastically - with the numerical solutions to Einstein equations... it looked too beautiful to be true," said Prof Danzmann.
Prof Sheila Rowan, who is one of the lead UK researchers involved in the project, said that the first detection of gravitational waves was just the start of a "terrifically exciting" journey.
"The fact that we are sitting here on Earth feeling the actual fabric of the Universe stretch and compress slightly due to the merger of black holes that occurred just over a billion years ago - I think that's phenomenal. It's amazing that when we first turned on our detectors, the Universe was ready and waiting to say 'hello'," the Glasgow University scientist told the BBC.

Big news!

^ An understatement that is.

If true.

Gotta love science!

Does this mean that gravity travels with the speed of light ??
Answering the question if the sun just disapeared would Earth take a straight line at that same moment or would we still follow an orbit for 8 more minutes.

That's what I get from this

We need to build a wall to keep these so-called "waves" out.

Darn waves, coming over here and messing with our gravity, ain't right I tell ya!

Einstein really was ahead of his time. Scientists in Scotland have been working to artificially create black holes in the lab to examine and study the interaction of light and gravity with black holes.

This is a fantastic discovery.

Meanwhile Presidential Candidate Donald Trump has released a statement confirming that he will not allow any undocumented waves into the U.S unless he knows it's religious affiliation or the waves are being unfairly targeted and persecuted.

And one half of the detector that found them is here in Louisiana! I've even been in it.

That's what I get from this

Gravity is actually described by two theories: Historically, it was Newton who first proposed a theory (Newton's Law of Universal Gravitation) while Einstein described gravity more accurately in his general theory of relativity. So, according to Einstein's theory gravity or better, gravitational waves, travel with the speed light just as light does, since it behaves like a wave.

Now, if we suppose that the sun suddenly disappears, we will take notice of the phenomenon 8 minutes after it happened, because 8 min is -approximately- the amount of time that has to elapse, before light arrives to earth (the distance between sun and earth is approximately 150 million km). As to what happens to earth, well, earth would abandon its elliptical orbit flying off in a straight line, just like you said. Next, it might be possible that earth could "catch up" with an outer planet since (earth) will be travelling with a greater speed. However, the sun has enough fuel for another 5 billion years so i believe we're quite safe for the time being.

This is truly a great discovery. I try to compare it with other great discovery or inventions we the human kind have done since way back.

I'm 49, and this is by far the most significant scientific story unfolding within the span of my life so far. In my book more significant than discovering and decoding the DNA, or the splitting of atoms. As I said, it is hard to overestimate this confirmation of Einstein's theory. It opens a whole new branch in astronomy-related sciences.

Did that incur roaming charges or is it covered in the basic service plan?...

Ansd another thing.

If we now know gravity waves expand and contract space, doens't that also mean Star trek warp drive is a ''legit posibility''
