There was no Earth, no Sun and, obviously, no annual revolution of the former around the latter, so what is the meaning of 400,000 years in this context?
.interstellar travel (thousands G of constant acceleration)
"Direct detection? That's funny."
In what way is the direct reception and measurement of gravitational energy from the event not "direct detection"? You don't believe in gravity?
@jones and parsec you know how the dector works? It basically splits light down two different arms perpendicular to each other and bounces it back and fourth then has it meet back up. The light should reach the dector at the same time due to the constant speed of light. The idea is that if a gravitational wave is passing through the distance for one photon will be longer than the other and there will be a slight delay between them.
First of all, this is not direct observation. It is indirect. Secondly it assumes relatively is right about gravity and what it is detecting is gravitational waves. My only beef with the detector is they should have had a third arm for XYZ rather than just XY
It's as direct as you can get. GWs are invisible :) In the same way that sound waves are. Do we directly detect SWs? Or do they make something vibrate that reveals their presence? Detecting a GW, and imaging the neutron star merger that caused it, is as good as it gets.
A neutron star? LOLOLOLOLOL. Why don't you measure the vibration and frequency of fairie wings?

This is why more than one detector was planned (and now exist).
@Jones vibrations from sound waves is direct. That is why they can't travel through the vacuum. Observing electromagnetic radiation with telescopes is also direct. But, these detectors are not direct. You would need something similar to how they measure the gravitational constant to measure it directly, but this indirect method is better. It is indirect because it is a two step process. The definition of indirect.
The era of gravitational wave (GW) astronomy began on 2015 September 14 when the Advanced Laser Interferometer Gravitational Wave Observatory (LIGO) made **the first direct detection of gravitational waves**, resulting from the merger of a stellar mass binary black hole (BBH; GW150914; Abbott et al. 2016b).
The rest of your post is just random words strung together. You should really see a doctor. You have some serious mental issue.
@jones the article is wrong. Maybe you should look up direct and indirect online. The are inferring the existence of gravity waves based on perturbations on the time it takes light to travel the difference arms. They perform a calculation and then use that data to infer the gravity waves. This is the definition of indirect. That is why some scientists were questioning what is really being observed.
Conclusions and outlook
The first*** direct detection of gravitational waves*** and the first observation of a binary black hole merger are remarkable achievements, but they represent only the first page of an exciting new chapter in astronomy.

These "observations" may as well be pixie wings beating between the two arms lol.
"The direct detection of gravitational waves from at least five sources during the past two years offers spectacular confirmation of Einstein's model of gravity and space-time."
Direct detection? That's funny.
...I'm pretty sure you have absolutely no clue what you are talking about (and probably not even how much of a sign saying "no education and no interest in getting one" you're pinning on yourself by your posts)

No Jonesdave, No.
"When a gravitational wave passes by, the stretching and squashing of space causes the arms of the interferometer alternately to lengthen and shrink, one getting longer while the other gets shorter and then vice-versa."
They are INFERRING that a gravitational "wave" is causing an interferometer to lengthen and shrink. Even the tolerances observed are incredibly infinitesimal. These "observations" may as well be pixie wings beating between the two arms lol.

Gravitational waves don't exist - they detected shock waves.
My biggest issue is the amount of noise these detectors pick up. Some of the GW without observational backup could be false positives, possibly something like turbulence deep in the earth's core. Also, the more likely scenario is that we are missing GW detections due to them being hidden in the noise even when compared to other detectors.
direct vs indirect does matter because direct is much more credible.
The point is it isn't 100% certain.
it cannot have a 3D design
@jonesdave,
I see that you are astounded by something that has never existed in you, because you do not possess what opens up aspects that enable you to know the true causes of the phenomenon. We are all formed by Aether, but many are drugged with some fatamagers from stupid and non-spiritual and unnatural theories. Most of you invented something and want to prove that this is his discovery of an event in the universe. Who are such people? Are they human beings and / or natural surrogates?
If you want to find out what AETHER is, invite me and you'll see how contaminated with stupid theories.
