Why wouldn't this work?

Would hit dielectric breakdown before a black hole formed.

im not talking black hole as in singularity im talking black hole as in light is trapped in it

>> No.8588509

It would most likely work; just wouldn't be a black hole.

If you have a light bulb in a small black box, can light escape?
Does this make it a black hole?
Does it demonstrate anything new to science?
Answer in one word or less, or alternatively never post again

That wouldn't "slow the speed of light", just change the amount of light reflected. The light that is absorbed will just used to keep electrons in a different energy state.

Why the quotation marks? Never heard of index of refraction?

Refraction doesn't slow the speed of light you goon, it just changes its direction.

It would work, you would just need a LOOOOOOOOOOOOOOOOOOOOOOOOOOOOOT of fucking black paint.

About 3 solar masses worth.

Do yourself a favor and look it up.

No, you do youself a favour. The speed of light does not change. The time it takes for it travel through n, where n=material changes, but not the actual physical constant. If it did change, then it would violate special relativity.

This.

The light in the material still moves at the same speed it just that it takes a longer path through the material due to bouncing around inside the material more ergo moving a further path distance.

The speed of light is constant. It is always constant.

>Get asteroid
How? You can't create one on a 3D printer.

>> No.8591331

Escape velocity is derived from the gravitational pull that the asteroid exerts on an object with mass. Light has no mass, therefore it does not get affected by the asteroid's gravity.
Although according to general relativity gravity does cause a certain effect on light, it would be too small to even notice.

Therefore, OP is a faggot.

>>8588253
You mean by covering the asteroid with high-intensity flashlights? That way the light heading towards the asteroid gets hit with the light leaving the asteroid and [redacted] happens
