The 2017 Nobel Prize For Physics Goes To Three Scientists Who Proved Einstein Right (fastcompany.com) 124

Posted by msmash from the recognition-time dept.
An anonymous reader shares a report: The three physicists, Rainer Weiss, Kip Thorne, and Barry Barish, won the coveted prize for the detection of gravitational waves -- the ripples in the fabric of spacetime that were first predicted by Albert Einstein a century ago. Weiss, Thorne, and Barish made the discovery as part of the LIGO/VIRGO Collaboration back in February 2016. It was then that they had recorded gravitational waves coming from the collision of two massive black holes a billion light-years away.

    Kip Thorne has done a lot of impressive work, not just on LIGO. In this context though, Thorne, Weiss, and Ronald Drever (who died last year and thus wasn't eligible for the Nobel), proposed a detector of this type in the 1980s. Barry Barish got the prize as the LIGO director.

    Since the initial work with LIGO, similar apparatuses are also coming online, including Virgo https://en.wikipedia.org/wiki/Virgo_interferometer [wikipedia.org] . There's also a proposal to set up a similar system in India https://en.wikipedia.org/wiki/Indian_Initiative_in_Gravitational-wave_Observations [wikipedia.org]. Having multiple detectors will have a whole host of benefits: this type of system has trouble detecting waves that come from certain angles so having multiple separate detectors will help cover those angles. Also, since we can measure the exact time difference from when a given wave hits the detectors we can use that to pinpoint the location much more narrowly. Along with neutrino telescopes, this sort of system is pretty much one of only two ways we can get information about far away stellar objects that isn't simply from the electromagnetic spectrum.

        While Morley and Michelson did make inteferometers, what they were using to measure was very different than gravitational waves, and relied on a degree of sensitivity many orders of magnitude lower (hence for example they didn't use lasers (which of course they couldn't because they weren't invented yet)). Many aspects of LIGO are so different than a classical inteferometer that it really should be regarded for most purposes as a different type of instrument completely.

          It's fundamentally the same measurement: is the speed of light the same in all directions, over time? Now we understand that there's no difference between detecting a change in distance and a change in the speed of light, but the instrument doesn't need to understand that. So, really, what's the difference in the instruments beyond sensitivity?

          Heck, the difference between GR and the aether is itself fairly subtle: turns out the aether moves along with massive objects, but substitute "flow of aether" for "

          • I realize that you're re-introducing the aether as a "fun theory" and that's fine. However, one of the overwhelming conclusions from the Michelson-Morley experiment is that the aether does not exist because if it did, we would be able to measure the earth's movement in relation to it. The need for "more complex math" to rescue the aether is a sign that we should set it aside because of Occam's Razor.

            That's not to say that one theory is "right" and the other is "wrong" -- they're both "right" if they agree w

            • Over time, additional reasons have been discovered for preferring the Copernican system. The primary one is that the Copernican model agrees with the law of gravity, which the Ptolemaic cannot be made to do. In concert with the law of gravity, the Copernican system also has predictive power.

              • Newton's law of gravitation provides the gravitational force between two bodies as a function of the distance between them. Therefore, it is independent of the co-ordinate system in which the bodies are observed, because the distance doesn't change in those systems.

                Newton's laws of motion are stated canonically for an inertial frame of reference. They can still work in non-inertial frames, provided one introduces pseudo-forces to account for the effects of such frames.

        It dates to the 1970s when they firmed up a lot of the rules (including that it could only go to at most three people). Prior to that, it had gone to someone who had very recently died. The thought process isn't completely clear. It appears that since the original bequest stated that the reward should go to work in the previous year (although it very often in practice does not), that if the person was dead, then they had obviously not done recent enough work. Another thought process seems to be that if it is in part to promote further work, then giving it to a dead person doesn't make sense.

      A bit more context - Barish was more than merely a director. While the idea was certainly Thorne and Weiss, Barish was the guy who came in and made the whole project actually work.

      As with most modern science, hundreds of scientists and engineers have worked over decades to get the result being celebrated. But if you have to pick three, this is a good choice. Note that while the Nobels are constrained to three people, the Breakthrough Prize is not: it was awarded to the whole collaboration last year.

      Yes, completely. If we had failed to detect gravitational waves it would be an incredibly big deal. Right now, we're trying to understand how to reconcile quantum mechanics and general relativity. If LIGO had not detected gravitational waves that would be a major sign of what to do, and would also help us see a large-scale area where GR breaks down (right now, QM works very well on a small scale and GR works very well on a large scale). Some people actively expressed disappointment that LIGO not only detected the waves but detected waves that matched the predictions of GR nearly perfectly.

    • It's damn difficult to prove that, since you didn't find it, it doesn't exist. A negation is, in fact, the complement within a set having a frontier which we don't know how far may extend.

      Had Weiss, Thorne, and Barish caught no waves even after decades, people might have begun to suspect gravity waves don't exist. No prize would have been granted for a suspicion, though.

      • It's damn difficult to prove that, since you didn't find it, it doesn't exist.

        Actually, conceptually it would be easy to prove that gravitational waves did not exist: just build a detector sensitive enough to detect gravitational waves from a source which is well known and understood and if you don't detect them Einstein would be wrong since GR makes clear predictions.

        Practically that is extremely hard because any source you are certain of will be so weak that it is almost guaranteed to be impossible to detect the waves it produces with current technology. This is why LIGO had to
