The Discovery of Gravitational Waves That Einstein Predicted - Professor Brian Cox

Gravitational waves are transient displacements in a gravitational field – generated by the relative motion of gravitating masses – that radiate outward from their source at the speed of light. They were first proposed by Oliver Heaviside in 1893 and then later by Henri Poincaré in 1905 as the gravitational equivalent of electromagnetic waves. In 1916, Albert Einstein demonstrated that gravitational waves result from his general theory of relativity as ripples in spacetime.

I swear I can listen to this dude 24/7. He is such a nice guy and so joyful about science. Absolute gem!

[johndardi]

Space is incredible. I don’t know how people go through their lives and never think about it.

[jasonkernes]

This man can make the most difficult concepts seem simple. He is fun to listen to.

[annesaffer]

I have learned so much from Brian Cox! What a great guy, a great communicator of the amazing things we haved learned about the Universe at all levels!

[SentientBiomass]

The great thing is that Einstein worked the physics for "population inversion", a process that occurs in lasers. Imagine if he'd been alive to see two completely separate branches of his research come together, one proving the existence of gravitational waves.

Mind-boggling. The FABRIC of the universe .

[vegasthornton]

I know right and he's like so excited you can tell how excited he is to share the information

[evabessioud]

OMG ! Everything that he says is sooo fascinating!!!

There is so much to unpack on this subject. First, congrats to those that accomplished this task and continued successful improvements.

In a dissertation on 5 May 1920 at the University of Leiden, Einstein introduced the term 'Gravitational Ether.' This ether is the transmission mechanism of gravitational waves. It is a compression-rarefaction wave. It has an additional property of inducing a very small magnetic field at its compresion regions of the wave. This new undiscovered property is predicated by the D-space theory. An adjunct theory to Space-time.

This theory predicts the reason for the slowing of inner stars of a galaxy, vanishing and phantom stellar structures, one mechanism for explaining hypervelocity stars to name a few. How these observed phenomenon are accomplished is for another post.

🤗that’s brilliant! Actually FEEL, detect the waves!

[rickelectric]

I like the idea of a fabric of the universe! I wonder what it's made of? I hope that it's cotton because wool makes me itchy.

Add a secondary axis with real-time arrays under each cross-section, syncing computer learners with attosecond pulses. By coordinating atomic clocks across distances, you create a super-precise internal accelerometer that filters out noise instantly. This setup not only boosts LIGO’s sensitivity but also refines spatial correlation across detectors.

That visual of gravity ripples collapsing into each other makes you wonder what physical reactions would take place there. If only we could see it in person.

[lunainezdelamancha]

I'm in ❤️ with this beautiful mind!

[judyroland]

Love to hear him speak!!! He could be reciting prayers and Everyone’ would be listening!!!

[chrispapa]

Wonder how enstien would be with all the technology today

[judyroland]

Gee’ imagine if we ALL spoke like this’ i dont think we would evr hv a “war”.., , ,
….

[sbcavo]

They did detect gravitational waves by the variance in the wavelength of the laser a fraction the width of a proton.

[andrewbarber]

Amazing. I wonder if we can feel these. I do feel sometimes time feels so much faster than other times. But in big chunks. Maybe this is these waves altering our sense of the speed of time. It’s only been a few days ago it feels things are running at normal speed after a really fast moving period of time. Might just be me on this but it is strange some time has gone so fast recently that I was sure was running at like x4 speed for a few months.

So thats why everyone around me shakes when i sit down.
