    Gravitational waves: breakthrough discovery after a century of expectation

    Scientists announce discovery of clear gravitational wave signal, ripples in spacetime first predicted by Albert Einstein

    Friday 12 February 2016

    Physicists have announced the discovery of gravitational waves, ripples in the fabric of spacetime that were first anticipated by Albert Einstein a century ago.

    “We have detected gravitational waves. We did it,” said David Reitze, executive director of the Laser Interferometer Gravitational-Wave Observatory (Ligo), at a press conference in Washington.

    The announcement is the climax of a century of speculation, 50 years of trial and error, and 25 years perfecting a set of instruments so sensitive they could identify a distortion in spacetime a thousandth the diameter of one atomic nucleus across a 4km strip of laserbeam and mirror.

    This clip is on LIGO from 2006


    Wonder why it took nearly 10 years to look at lasers and mirrors in order to find gravity waves though.

    Listen to Tyson attempt to explain how it was discovered


    • "Bad *** black holes coalescing did it"
    • "a fraction of the diameter of an atomic nucleus"...

    "Any vibration will affect this thing"

    So much so they inform people "beem on, drive slowly", yet they see this process as reliable?

    Not to mention there was a slew of videos on gravity waves in the last year... nothing really between 2007 and 2014

    Well aside for this mention

    Gravity Waves from Big Bang Detected

    A curved signature in the cosmic microwave background light provides proof of inflation and spacetime ripples


    By Clara Moskowitz on March 17, 2014

    Physicists have found a long-predicted twist in light from the big bang that represents the first image of ripples in the universe called gravitational waves, researchers announced today. The finding is direct proof of the theory of inflation, the idea that the universe expanded extremely quickly in the first fraction of a nanosecond after it was born. What’s more, the signal is coming through much more strongly than expected, ruling out a large class of inflation models and potentially pointing the way toward new theories of physics, experts say.

    “This is huge,” says Marc Kamionkowski, professor of physics and astronomy at Johns Hopkins University, who was not involved in the discovery but who predicted back in 1997 how these gravitational wave imprints could be found. “It’s not every day that you wake up and find out something completely new about the early universe. To me this is as Nobel Prize–worthy as it gets.”

    Scientists got it wrong on gravitational waves. So what?

    Well see, what had happened was....

    Friday 26 September 2014

    It was announced in headlines worldwide as one of the biggest scientific discoveries for decades, sure to garner Nobel prizes. But now it looks likely that the alleged evidence of both gravitational waves and ultra-fast expansion of the universe in the big bang (called inflation) has literally turned to dust.

    Last March, a team using a telescope called Bicep2 at the South Pole claimed to have read the signatures of these two elusive phenomena in the twisting patterns of the cosmic microwave background radiation: the afterglow of the big bang. But this week, results from an international consortium using a space telescope called Planck show that Bicep2’s data is likely to have come not from the microwave background but from dust scattered through our own galaxy.

    Some will regard this as a huge embarrassment, not only for the Bicep2 team but for science itself. Already some researchers have criticised the team for making a premature announcement to the press before their work had been properly peer reviewed.

    So when will this be added to the science books in public schooling?
    Not sure if this can be recreated in a high school lab, but hey... does that matter really?

    Host:
    • "That's detectable with a mechanical setup.... stop"

    Tyson:
    • "Any vibration will affect this thing"

    Host:
    • "How is that accounted for"

    Tyson:
    • "There a ways to insulate it from what is going on"


    Though Tyson tells that they need to drive slowly as to not affect the results.



    A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—including particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.


    These two black holes supposed combined 1 billion years ago and now we can see them releasing waves... which nothing can escape from inside it.

    Are these waves ripples or vacuums?

    Is gravity caused by these waves, or does gravity create this waves?

    Sounds like people going through portals a mass is a plausible explanation for why its causing riffs in the gravitational field

    There was a "teleportation" (and not relating to telecommunication) bill proposed and passed by congress.

    Of course it would be like trying to find a needle in a haystack now, as it has probably been purged.

    I have the printout somewhere, but would have to look through some old binders.

    Who knows what they are doing and what they are not sharing.
    Research Project Pegasus and the Time/Space programs

    Hope I can find the House Bill as well.

    I kinda caught wind to this, as it seems like these "two factions" have been going back and forth trying to win public opinion of sorts for the last 2 years.

    Does seem like an interesting coincidence that this "gravity" thing is constantly in need of attention.
