No it isn't

It's just that mediums will change it-

It is.

If it wasn't things in resin would travel every time a different evlocity.

the speed of light is constant in a vacuum

It's just the resin that does a force of slowing it down.

force you say?

Hang on I thought light had no weight

Light has no mass....

What's mass?

Mass is weight times acceleration.

But weight isn't accelerating

That has nobody said.

It's weight times acceleration.

So if I have a brick on the floor not accelerating, it has zero mass correct?

No..

Because the accerlation is not Zero.

So why aren't the bricks, lying on the floor, moving?

´Because the earth is moving.

I don't believe you, I don't feel like the Earth is moving

You don't have to feel it

because i n a car contantly moving you won't fell a thing.

Yes I do, I feel the bumps and the wind and the rattling and the corners

Only if it accerlates or changes direction.

Where are the bumbs in earth movment?

but then it would not be constantly moving if you can feel bumps

So the Earth is neither accelerating nor changing direciton, correct?

Where is the wind and the ratteling in earths movment?

I don't feel wind and rattling on the Earth, do you?

How exactly is this helping your case?

Why should you feel wind?

Or ratteling?

there is not a ether

I don't know, because the Earth is mostly flat and not moving

@Minotarus No it isn't
