A head-vaporizing laser with a perfect wavelength detecting sub-proton space-time ripples.
Huge thanks to Prof Rana Adhikari and LIGO: http://ligo.org
Here's how he felt when he learned about the first ever detection: https://ai-tube.com/videoai/IvZaTta87qt

A lot of videos have covered the general overview of the discovery of gravitational waves, what they are, the history of the search, when they were found but I wanted to delve into the absurd science that made the detection possible.

When scientists want one megawatt of laser power, it's not just for fun (though I'm sure it's that too), it's because the fluctuations in the number of photons is proportional to their square root, making more powerful beams less noisy (as a fraction of their total). The smoothest mirrors were created not for aesthetic joy but because when you're trying to measure wiggles that are a fraction the width of a proton, a rough mirror surface simply won't do.

what a load of vomit FFS , , you morons make christians look smart , you may now all go durp

I like how the national science foundation which funded this has a symbol of everyone holding hands around the world, considering the politicians funding it have only one thing on their mind. Will this keep our guns bigger than anyone else's guns.

waste of money on a fantasy.
everything in the universe is in motion so you need to know every aspect of everything and their properties which makes it impossible to measure.
also our knowledge of the universe is based on standard models which in turn are defied by facts on daily basis.
in short : we can't measure or detect stuff which doesn't comply to our standards thus making this all nonsense science !

Thank You.

prof Rana is the coolest scientist ever.. great video mann.. nice ..

So... is the wave propagated through the Higgs field then? Does that make the Higgs field equivalent to Aether? Except instead of the magic invisible substance that holds things in space, it’s the magic invisible substance that gives particles mass and presumably therefore gravity... And in any case, what is gravity?

Asking for a friend.

Quantum mechanics and Digital Quantum Physics will get us there soon

If you worried about the photons use a magnetic field to control the amount of photons going through the laser beam.

space force laser guns almost here

Next time please have the camera focus on the subjects in the shot rather than on the background 1m behind.

even more absurd is that people actually think that this is even possible.

This doesn't surprise me given that holograms are created using laser (coherent) light, and at the scale of an atom, details of an object can be analyzed for inconsistencies against the image of the hologram.
Able Fable
Dosen't this prove pilot wave theory
Kandela Brown
Meanwhile; solutions to real problems don’t get funding.

What I'm wondering is: How do we know these black holes existed, let alone merged if these waves travel at light speed?

Why can't the Higgs field be the field that gives energy rather than the field that gives mass? It would give small particles energy and the large objects energy but the large objects get energy in to go in multiple directions so they just continue on in one direction. the smaller the particle the more it's motion is spurred on by the field in random directions. That's why photons travel in in random motions. The field causes a photon to move in random directions because it has so no mass. A single photon can't be a ray. A ray is comprised of multiple wave fronts and multiple photons.
