Light is amazing ~ some factoids

@ponderable said
So at least in Germany "Sonnenufgang" is defined, when you observe the sun coming over the horizon, that the incoming light is actually a bit dated at that time is not of relevance.
Since the sun is emitting the light in all directions (quai) homogenously. The light is alredy 8 minutes travelling, but is arrives directly at the sunrise time.

You’re just getting yourself mixed up with with you see, and what has actually happened when you watch a sunrise.

Gravity bends light. The more gravity you have, the more the light bends.

and

Light doesn't need a vacuum to "get bent" (refract).

Well… I’m not sure that that is entirely accurate.

David Burton has a good question; how can light with no mass be bent by gravity.

The answer is along the lines of … gravity warps space and therefore impacts the lines of direction along which light can travel. Light itself is not affected by gravity.

It’s something like that.

Regarding car headlights and the speed of light, I recall an old wise warning in driving school, and it was that we should never overdrive our headlights.

Who says we can't go faster than the speed of light? In light of imagination we can leave light standing still..... warp drive. Just warped imagination?

Just another theory, as far as not being able to travel faster than light. If man can imagine it, it can be done..... some day. But on that day we will not be able to see the light of day, as it will always be in the past, trying to catch up.

Light is indeed amazing for those who can see it directly, and not as mere reflection.

I’m not far right, I’m not a Royalist, i have the same “perspective on life” as most people including yourself. Everyone loves vanilla.

I don’t think we are poles apart; you’re making assumptions here.

I’m a Stones fan over the Beatles; Floyd, Zeppelin, Free, Hendrix. And I also like ELO and whatever music takes my fancy.

Anyway, is musical taste such a divider or people in your mind?
