That's a misconception. Light travels at the same speed regardless of its frequency. It doesn't change with intensity, either.



Yup, Cherenkov radiation is effectively a sonic boom. How cool is that?! Read all about it, here:



It's about 1.3 seconds to get to the moon, quite a bit faster.
I knew it wasn't instantaneous and heard that 4 seconds was the delay value at one time.
1.3 however does sound more reasonable.

It has been proven as fact in the case of black holes, lines of magnetic force do emanate from a black hole and that means it's coming up from the hole through it's event horizon.
So if you must go faster than light itself to make it up and out of the event horizon, well - There you go.
I highly doubt this is "fact" but as a non scientist I cannot explain why.

Was it shown specifically to emanate FROM it? Because I see plenty of proof for magnetic fields in the immediate vicinty of a black hole, but not necessarily emanating from it.

Hawking radiation is emanating from black holes specifically and it is due to quantum effects which are still yet to be combined with relativity in all-encompassing way.

Nobody has measured yet because Mother Russia hasn't found way to send dog faster than speed of light yet.

Schrodinger, he used cat... but the collapse of the quantum wave function, it beats the speed of light.

Dyson suspected that there may be no need to combine, that gravity can stay classical.

It has been proven as fact in the case of black holes, lines of magnetic force do emanate from a black hole and that means it's coming up from the hole through it's event horizon.

The magnetic field is one thing, electromagnetic radiation another. The second emanates, the first is just frozen in.

Had to re-research it from what I recalled earlier to make sure. I know once I saw an article/vid about magnetic fields and black holes that was beyond just interesting.
I believe this is it along with a few others for additional reading about this and related things.

Massive Black Hole Photographed Reportedly 'Burping' Light

Magnetic Field around a Black Hole Mapped for the First Time - Scientific American

Magnetic Fields May Be Key to Black Hole Activity | NASA

This seemed interesting enough to include:

Galaxy Survives Black Hole’s Feast – For Now | NASA

What will we find in the next 10 years that's gonna make us lose our minds over what we think we "know" today?
Time will tell and should be.... Interesting.

This issue is the nature of timespace both at a quantum level and at galactic size. Since all timespace is curved the direction light travels is unimportant, as emr travelling on the x axis is also travelling to some degree through the Y & Z axis. It very likely that if light had a different speed for the opposite of a particular direction there would be measurable outcomes. The comparison with antimatter v matter is unfortunate and misplaced. The video is like candy for the high IQ audience. I am concerned some might take it seriously and it could a physics earworm.

Given the continued efforts to unify the two, it doesn't seem likely to be the case.

One could argue the other way around; so much effort for so long and still no success.

That's most definitely not a winning attitude, not just in science, but in many other aspects of life.

Try harder.

:p (added to make it clear we're playing here)
I can play to
Just asking when in Time that is
Precession – As Earth rotates, it wobbles slightly upon its axis, like a slightly off-center spinning toy top. This wobble is due to tidal forces caused by the gravitational influences of the Sun and Moon that cause Earth to bulge at the equator, affecting its rotation.

This is Science, not Engineering.

Classical it certainly isn't, though on certain scales it is good enough approximation. If anything, perhaps you meant described by GR.

Or maybe has duality, much like light.

Or maybe it is neither. And we have to start building theories from scratch...
