LIGO

[authorgonal]

Whilst I am of the opinion that the LIGO project (google it) is flawed in its basic assumptions I think it unfortunate that there are some that use its failure (to date) to suggest that Einstein was wrong.

IMO gravity waves are 4d. That is to say that whilst 3d space will stretch and compress as a wave passes - also, because it is 4d space/wave, - time will similarly expand and compress.

A longer distance traveled by light will be offset by slower time 'n vice virsa.

LIGO failure then is not an Einstein failure but cos we are dumb

The idea that time can stretch and compress may be a difficult concept to accept. Therefore, I am adding this comment to show how simple the idea is - given a particular assumption.

The assumption is that time acts over a distance. Admittedly the time distance is orientated orthogonal to the 3 spatial dimensions with which we are familiar. Clearly the extent of our 'now' extends minimally to the future and minimally to our past.
It follows then that 'time passing' must be our 'progress'/ 'process' along the distance/direction of time.

Bear in mind that if we stretch space then any ruler contained within will also be stretched (in equal proportion).

Similarly a stretch of time will also 'stretch' our clocks. That is to say such stretching will not add time: a second stretched will still be a second - although admittedly a long second!

As a consequence the stretch and compression associated with a passing gravity wave can stretch and compress time i.e. the 'length of a second' in distance will match the 'stretch of a spatial distance'.

Clearly the spatial stretch/compression will have (ligo assumes it will have) a spatial orientation. It will act radially to the origin of disturbance that causes the gravity wave. Similarly our (the universe's) direction of time is radial for any object anywhere. My posts here have often referred to this issue - we can examine this again if anyone wishes to.

So, the disturbance - nova or whatever - will cause a spherical gravity wave and a spherical 'time shock' (my poetic name for stretched/compression of time). That is a nova, say, will be hyperspherical in spacetime. Clearly the radial direction of the shock is from the past to the future.

This synchronization of direction will mean that any attempted L.I.G.O. detection of 'stretch/compression' by light (traveling at c of course) will be nullified by an exact change in the 'length of a second'. Even though a gravity wave has passed there could be no detection of a time increase/decrease by light (c).

This begs the question " How can we detect gravity waves?"

So, how do we detect a gravity wave?

We already have a clue: The lensing effect caused by gravity shaping space. The light is BENT by the gravity depression of massive objects e.g. a galaxy. Shaped space bends nearby adjacent passing light.

In this case there is no 'timing' involved. It is simply the slight apparent bending..

Gravity waves are distorting (shaping) space. We should try to detect distortions (bendings). Light (a laser) should wobble as a wave passes. If the detectors are sufficiently far from the laser source we could perhaps record the amplitude etc......

Hi it's me again. I like to come back here each year just to reinforce my prediction that LIGO would achieve ZERO results. Not because Einstein was wrong but because the basis for the experiment is (IMO) flawed.
Not one iota of positive data has been received. Zilch. $'s down the loo. Years of effort for a zero detection rate. Similarly ALL gravity wave detection experiments - Zilch!
Why? Ok, I'll say again: Any such wave will be a 4Dimensional wave. 3d space + time space. This means that variations of any 4D dimension would be undetectable as our measuring instrumentation would alter in concert. Simple.
The 'official explanation', LOL is that the waves must be so tiny in dimension that they are beyond the instruments capability....
Which is why 'they' are spending more to achieve more n more 'magnification'. Lets face it that is feasible - it also explains why we cannot see Fairies....
