Space Time Ripples and Einstein's Legacy

Headline news was made earlier this year when the detection of gravitational waves, caused by the collision of two black holes, was confirmed by the Laser Interferometer Gravitational-Wave Observatory (LIGO). And earlier this month, another ripple was detected! The observed ripples in the fabric of space-time validate a key prediction in Albert Einstein's theory of general relativity. One hundred years old, the theory continues to astonish scientists with how correct it is. LIGO’s discovery signals a new era of astronomy and a new way of understanding the warped side of the universe.

How many how often and what range you get these chirps a statistics of time difference etc. Can they run for a few years. Angular variations. Merge and separation knitting pattern. They have to merge and also split and cross over.

[@awsesometech1791]

I think Lisa Randall lost everyone when she spoke about the elctroweak phase transition energy, Higgs Boson, and that LIGO might be able to detect this transition because the frequency happens to be the same as that of gravitational waves. I think she was saying that this instrument, LIGO, might also detect, essentially, fundamental particles acquiring mass in this transition, and that is exciting because it verifies that this transition occurs and lends more support to the Higgs field/boson. That would be cool, two for one for LISA.

Before Big Bang the space was sheets of line polarity. Like flakes of polarity sheets. Empty. Even if you have a single sheet it has polarity. There are two kinds of mass stretching mass and compression mass after Big Bang. Light interconnected both. Light or black holes or matter was not there before. You can never get to that state before Big Bang because time is not there. Whatever your measure in space is relative to time. Our universe was one of such flakes combustion. Golden ratio line of symmetry.

[@venkatbabu186]

If we want to visualize something it is like a tan(π) curve. Why a tan theta. Two waves dividing each other orthogonal. One a sin wave and an other cos wave. A wave means time so two times dividing each other orthogonal. Sin divide by cos gives tan. Tan 0 is zero unless perturbed. But a slightly perturbed wave gives tan theta some value. Say diameter of sun to that of diameter of the solar system. That is a tan wave and has an inverse angle of about 0.00005°. Might be zero is considered light and a little bit higher gravity and a little higher angle tan wave is asteroids planets sun star etc. But getting all this ratio and taking an inverse angle could explain the frequency of each of planets and similarly subatomic like that of the radio of diameter of atom to that of diameter of nucleus etc. For black holes the angle is about 0.0001°. How can you create waves. Say you are moving water in a bucket up and down at a frequency then you cannot get a wave. But if you have a stick moving right to left at a frequency then you have ripples. So always two times or two frequency is involved in a ripple. Or you can spin something over the water to get ripples. The basics of waves conception. Without a tangent things cannot be created.

A single photon or sphere of heat energy(smallest sphere in the universe) do not posses intrinsic spin and virtually no mass or weight but when it is grouped or attached to other photons thru its fields. it will begin or began to gain spin and gain mass or weight...when it is in the size of electron (10 exp 42) it will spin to the left and then reduce its speed to 10% less that of light speed!

[@horseofblack]

why do they ignore the motion of the oceans as an interferometer type gravitation detection device? the oceans react to the changes of mass (sun and moon) just the way the laser devices acted except for the scale sensitivity built into LIGO. well, there was no money in writing a paper on such a mundane local event as tides versus building a billion dollar machine with highly sophisticated conversation to explain it.

[@Alkis05]

Im just an engineering student so take what I say with a grain of salt, but what the are measuring is not exactly gravitational forces as we think of them, but ripples in space-time. That is space-time vibrating, stretching and contracting. For you to measure the shape of spacetime you need for something to move through it without disturbing space time. Fotons (i.e. light) travel at the speed of light (obviously) and dont disturbe spacetime because they are massless. Imagine you are trying to measure waves of heat passing through a metal ruler. By studing the way the ruler dilates, you can learn about the heat wave. But again, I'm not sure this is the right way to think about it. That is just the way I understand it.

[@SJ-to3dt]

+Alkis05 you are right.. In addition to that, the argument previously made about oceans in that the tidal action is sufficient to prove the effect of gravitational waves is flawed.. Because the level of water is essentially controlled by gravitational forces exerted by moon, sun and the rotation of the earth.. It in no way represents the distortion phenomena and can be sufficiently proved by Newton's law of gravitation

[@sclogse1]

Photons are considered to be a wave and a particle. Particle equals mass.

[@Alkis05]

Particle doesn't imply mass. Photons are massless particles. Weirdly (and that is what their particle aspect come from) photons have linear momentum related not to their mass, but to their energy and frequency.
