Just one on the topic. I did not check to see if it was Pro Constant, or Pro Variable

While an interesting study, and no doubt legit for the most part, it is a significant challenge to measure the timing of light. I intend to look in to it deeper for info about the control.

I am not even remotely trying to challenge the concept, because it makes absolute sense that manipulating a photon to a different state and back would change velocity...
However, bends, imperfections, connections, all have a significant effect on a fiber line. It is not a straight arrow shot down a fiber, the light refracts off the cladding and through the glass of a fiber, bouncing back and forth throughout the line.
So if they took fiber A, shot the light, and then introduced an item to change the path, I wonder how they compensated for the different pathway in the test.

Since they are measuring miniscule time spans, the minutia becomes important... I use a couple items for work that depend on the speed of light, and variables can alter readings significantly.
They are time domain reflectometers, both standard and optical. They both work on the same premise- they shoot a pulse and read how long it takes to bounce back to the unit- the speed compensation has to be calibrated to the item being tested, or the results vary wildy.... the pulse is read at normally between .84 and .99 times the speed of light, because there is attenuation for any pathway light travels outside of a perfect vacuum.

Looks fascinating.

This is a big deal. When scientists first developed the infrastructure to detect electromagnetic waves there was zero concept of what they would unlock - ie radios, broadcast TV, microwaves, wireless phones, cell phones, wireless internet... and on and on...

Detection of gravitational waves could be on the same order of magnitude of discovery if we can figure out how to manipulate them like we did with EM waves.

It's also kind of like having a whole new sense while observing the "heavens". Like being able to hear as well as see.

unfamiliar with this, but thanks.

Ah my bad, thought that's what you were referring too.

To add...

If we figure out how to manipulate (ie create and control) gravitational waves, that will allow us to control the shape of space. Which in turn would allow us to manipulate the flow of time. Yes, just confirming that gravitational waves are real is a tiny little step. But this is some big shit.

So how do we know black holes collided over a billion years ago?

Please splain that to me in religious dummy terms.

You want someone to break down 6 weeks worth of course content from the most bleeding edge of one of the most complex scientific disciplines in a post on a football forum?

Sounds like a challenge Bot... You can do it!

Yes.

 

[JosMin]

TL;DR

Not enough pictures and I'm not stoned. Yawn.

I don't see the issue.

I don't see the issue.

You would dispute it with bible stuff anyways, so what's really the point?

The point is you're wrong
