http://www.dtc.ox.ac.uk/people/13/quevedocamargof/papers/GravitationalWaves.pdf - for the paper published in Physical Review Letter.

Today reminds me of July 4, 2012, while most were celebrating the fireworks I had a little bit different kind of explosion that I was celebrating. The Higgs Boson had been confirmed, through exploding protons near the speed of light, by the LHC and CERN teams that day, and the official announcement had been made that granted the Nobel Prize more than 40 years after it's prediction by Higgs & Elliot.

Einstein always has to one up everyone though, and Gravitational waves were predicted in 1915. Finally we are able to confirm they exist!!

JUST SO YOU GET A SENSE OF HOW AMAZING THAT IS

LIGO & VIRGO are the teams that detected the waves. So a Gravitational Wave is basically a warp in space-time, kind of like a burp, or ripple. In this case, a binary merger black hole was observed, and at this point I will quote esteemed Theoretical Physicist Lawrence Krauss who describes it nicely: "A black hole with a mass 39 times the mass of our sun collides with another black hole 26 times the mass of the sun, comes together to make one big black hole that’s 62 times the mass of the sun. If you do your addition, 62 is not 39 plus 26, it’s three solar masses smaller. Three solar masses of energy went in a second into gravitational waves. … Our sun over 10 billion years is only going to convert a small fraction of its mass into energy by burning 100 million hydrogen bombs every second. But in one second or so, in a very short time — BOOM — three times the mass of the sun was converted by E=mc² into energy. It’s unfathomable. It just disappeared. Imagine our sun just disappearing in a second.”

What's truly astounding is that this merging of such an event created a ripple in the curvature of space time that we detected 1.3 Billion Light Years away - the LIGO detectors are 4km long and can detect a difference in length of up to 1/100 of a proton with precision. ( the measurements are in a metric called strains, but that is a whole different can of worms) What is more amazing is the literal precision our experimentalists have achieved, cancelling out all the external noise to detect this is no easy feat, and I cannot stress that with proper justice. We are now hearing the universe in a completely new way, and I look forward to observing the adventure that science is currently on.

For my Physics nerds - an amazing Kip Thorne lecture

Hey Shis!

I was thinking about making a thread on this, but didn't think CR General would like it. I guess I was wrong!

I read this and it really amazed me. Einstein was a true genius! He is one of the reasons I absolutely love space. I actually read that .pdf for fun one day in Physics class in High school. Did I understand it all? Nope! Would I now? Probably not haha.

I can tell you though I had a drink in Einsteins name today. A nice glass of red wine. I look forward to seeing how the board of CR reviews this!

Good night!

its amazing what humans are capable of. somehow, artifical gravity doesnt seem so far fetched.
i wonder how long till someone figures out theoretical FTL travel.

My physics professor talked about this a few days ago before he went to Washington for the press conference. He looked like he was about to cry when talking about this since he had been working with LIGO since the beginning.

Theoretical means of FTL have been described. They require compressing space and inverted gravity wells.

In my head I actually added 39 and 22 together and couldn't figure out how that was supposed to be 3 larger than 62...

Leave me alone I'm tired...

If this doesn't help me cook pizza more evenly, idk why they're even studying it.

I totally understand this man ^^. I have nothing to do with this project and I will never be involved in anything like that but I was so happy about it I was almost crying. Couldn't stop smiling for about 2 hours, even though it was obvious what they will announce.

I tried, but my brain started to hurt. Now I have to go to the emergency room to have my brain checked out. I think I strained a brain cell. (LOL just kidding! No, wait. this thread is too smart for me, but I'll make time to see the Einstein video ---- some day.)

yeah, but a einstein rosenberg bridge is still not FTL. or are you thinking of something else?
