Gizmodo: "The Biggest Scientific Discoveries of 2016. Gravitational Waves Are Real, Baby. We're all intuitively familiar with the concept of spacetime, you know, that four-dimensional container you eat, breath, shit, and grow old in. But as it turns out, spacetime is not a rigid box. Rather, it's a rippling ocean, alive with subatomic waves generated when black holes, neutron stars, and other incredibly massive objects collide. Called gravitational waves, these spacetime ripples were first 'heard' by LIGO's detectors last September, although the discovery was not announced until February.

"Nature's 10. Ten people who mattered this year. A year ago, Gabriela Gonzalez was struggling to contain the biggest secret of her life. Two giant detectors in the United States had picked up signs of gravitational waves — wrinkles in space-time imagined by Albert Einstein but never before directly witnessed. It was Gonzalez's job to help lead more than 1,000 scientists in their careful efforts to verify the discovery before announcing it to the public." http://www.nature.com/news/nature-s-10-1.21157

My comment in Nature:

Gabriela Gonzalez allegedly discovered "wrinkles in space-time" but the problem is that space-time, the absurd consequence of Einstein's 1905 false constant-speed-of-light postulate, does not exist:


Nima Arkani-Hamed (06:09): "Almost all of us believe that space-time doesn't really exist, space-time is doomed and has to be replaced by some more primitive building blocks."

https://www.edge.org/response-detail/26563
Nobel Laureate David Gross observed, "Everyone in string theory is convinced...that spacetime is doomed. But we don't know what it's replaced by."

https://edge.org/response-detail/25477
What scientific idea is ready for retirement? Steve Giddings: "Spacetime. Physics has always been regarded as playing out on an underlying stage of space and time. Special relativity joined these into spacetime... [...] The apparent need to retire classical spacetime as a fundamental concept is profound..."

http://www.amazon.com/Faster-Than-Speed-Light-Speculation/dp/0738205257
Joao Magueijo, Faster Than the Speed of Light, p. 250: "Lee [Smolin] and I discussed these paradoxes at great length for many months, starting in January 2001. We would meet in cafés in South Kensington or Holland Park to mull over the problem. THE ROOT OF ALL THE EVIL WAS CLEARLY SPECIAL RELATIVITY. All these paradoxes resulted from well known effects such as length contraction, time dilation, or E=mc^2, all basic predictions of special relativity. And all denied the possibility of establishing a well-defined border, common to all observers, capable of containing new quantum gravitational effects."

http://www.guardian.co.uk/books/2013/jun/10/time-reborn-farewell-reality-review
"And by making the clock's tick relative - what happens simultaneously for one observer might seem sequential to another - Einstein's theory of special relativity not only destroyed any notion of absolute time but made time equivalent to a dimension in space: the future is already out there waiting for us; we just can't see it until we get there. This view is a logical and metaphysical dead end, says Smolin."

http://www.bookdepository.com/Time-Reborn-Professor-Physics-Lee-Smolin/9780547511726
"Was Einstein wrong? At least in his understanding of time, Smolin argues, the great theorist of relativity was dead wrong. What is worse, by firmly enshrining his error in scientific orthodoxy, Einstein trapped his successors in insoluble dilemmas..."

https://www.perimeterinstitute.ca/research/conferences/convergence/roundtable-discussion-questions/what-are-lessons-quantum
Perimeter Institute: "Quantum mechanics has one thing, time, which is absolute. But general relativity tells us that space and time are both dynamical so there is a big contradiction there. So the question is, can quantum gravity be formulated in a context where quantum mechanics still has absolute time?"

http://www.newscientist.com/article/mg20727721.200-rethinking-einstein-the-end-of-spacetime.html
"Rethinking Einstein: The end of space-time [...] The stumbling block lies with their conflicting views of space and time. As seen by quantum theory, space and time are a static backdrop against which particles move. In Einstein's theories, by contrast, not only are space and time inextricably linked, but the resulting space-time is moulded by the bodies within it. [...] Something has to give in this tussle between general relativity and quantum mechanics, and the smart money says that it's relativity that will be the loser."

There were gravity wave detectors
like the cryogenic Weber bar for
more than fifty years before LIGO.

Spacetime: Minkowskian: to be
replaced by itself. Though, it
might be that the interpretations
might be giving way with some re-
thinking of decisions about the
interpretation of data given that,
for example, it's been pretty recently
discovered that since the beginning of
radio astronomy, the "expanding universe"
was actually that we're in a large jet
called LaniaKea, with that then what it
appears is that space-time is "mostly
flat", that the curvature of space-time
or Einstein's cosmological constant:
is really a mathematical infinitesimal.

So, physics doesn't need a new "space-time",
but it does appear that it needs to rebuild
a lot of stuff that's stacked on that.

This can help now reduce the various
"catastrophes" and "curses" in physics
and various usual "off by 10^120" (all
the way wrong) problems.

String theory is quite salvageable but
it's not really clear with the received
mathematics how that is. String theory
is a model of the infinitesimal grain
about as many orders of magnitude smaller
than atoms as atoms are smaller than us.
(That's about what it is, and, why it is.)

Velocity is still relative to light in
a vacuum, and information transfer still
finds that maximum.

Gravity is effectively immediate in its
effect, gravity waves are very energetic
and extra-classical as for example when
dual neutron stars collide, or for example
a bow shock of discarding a mass shroud,
in effect.

Space-time quite well exists,
and it's our classical medium.

Part of the reason that controversy is compelling
is because there's a chance to learn or know the
changes in the dogma as they happen, to be a part
of not just learning but discovering.

Cynicism and skepticism combine for both that
the dogma is critically evaluated with cynicism
and skepticism, and also new results are critically
evaluated with cynicism and skepticism, and also
that there is room for both the new and the
dogmatic with skepticism, as a healthy inspection,
and cynicism, as a guarded reserve.

"You can tell the pioneers from
all the arrows in their back."

Pentcho Valev as skeptic and cynic (for
the critical evaluation in the face of
controversy) with his particular items
(Doppler, these days the Chicken Little's
of the diaspora of superstring theory)
may not offer much in the way of the
constructive development, but, where there
may be an oversight or error in the dogma,
and as we will discover as science goes on,
the role of skeptic and cynic is as necessary
for discovery as the disseminator and
instructor is for learning, but, there
isn't one without the other.
