The sky can flash all it wants, but I ain't starting' over, Dilbert.

This light could burn your eyeballs right out of your skulls.

Do we have evidence of this? Yes, coral reef systems.

But how do we know in advance which photons will matter?

Light and sound travel in waves.

Hey, Doc.

It's used in paint for the texture, but also for the glossiness.

Did you get their names?

And that changes everything.

So those kids on the edges aren't actually receiving effective phototherapy.

And this is what the planet looks like.

limited in the vision that they can provide.

And all the light that we see from a typical galaxy, which is the kind of galaxies that we're seeing here, comes from the light from the stars.

Wow, it's swarming with tourists!

It doesn't get underneath the translucent

like that pencil on your desk, are simply reflecting light from a source rather than producing their own.

It set to take a life, perhaps our own.

Therefore they will be screened off from their Lord that day,

Yes indeed they will be deprived of seeing their Lord on that day.

No indeed but upon that day they shall be veiled from their Lord,

By no means! Verily on that Day from their Lord they will be shut Out.

Nay! Surely, they (evil doers) will be veiled from seeing their Lord that Day.

Not at all. On that Day, they will be screened from their Lord.

No indeed! On that Day they will be screened off from seeing their Lord,

Nay, but surely on that day they will be covered from (the mercy of) their Lord.

Indeed, they will be alienated from their Lord on that day.

No indeed, on that Day they shall be veiled from their Lord.

No! Indeed, from their Lord, that Day, they will be partitioned.

On the Day of Judgment, they will certainly be barred from the mercy of their Lord.

Nay! most surely they shall on that day be debarred from their Lord.

Indeed! On that Day a barrier will be set between them and their Lord,

Verily, from (the Light of) their Lord, that Day, will they be veiled.

So all the light in this area from the sun and the moon is what you see on the screen right here.

The light... is strange out here, isn't it? It's...

Any minute the sky could light up, and who the hell knows what could happen this time?

And the pleasure's all mine.

That's just great.

Good.

No, nothing.

I could not help laughing at the sight.

This is a pulse of light that's only about one wavelength of light long, so it's a whole bunch of photons all coming and hitting simultaneously.

Yeah!

And then I came across this material fiber optic, which usually emits light at the end of this light, as you can see.

You know what I mean?

Soft and fat.
