The beams, known as spacetime wave packets, follow different rules when they refract, that is when they pass through different materials. Normally, light slows down when it travels into a denser material.

I am a dummy layperson, but I thought the speed of light was constant? What am I missing?

The constant c is about 3*10^8 m/s in a vacuum. Any media it travels through, such as air and water, slow it down in proportion to its index of refraction. That slowing down changes the direction slightly, which is why things appear bent if half-submerged in water.

That's some voodoo shiate right there.

Science!

I believe the scientific jargon is "spooky action at a distance".

Or "I'll show them ALL! BWAHAHAHAHAH!!!" Once the discovery has been properly engineered into Death Ray- form.

AND this also applies to sound as well, which is why the people in Beirut felt the explosion in their feet before they felt in anywhere else, because sound moves faster through the earth

No it doesn't

Not dumb, just a common misunderstanding. Photons move at different speeds in different media. The "universal speed limit" is the speed of light in a vacuum- roughly 300,000 Km/sec (the "c" in Einstein's equation). This is a pretty reliable velocity, observational data matching theoretical predictions of the Standard Model with high confidence. Photons can't go faster than C in the Standard Model, but can be slowed down- by passing through water, for example.

Sound travels faster through denser mediums, so yes, it really would.
