Another one was making some assumption about how much dust there is that blocks ultraviolet light.

And based on that, they got a result that there is a lot of water.

And then the Webb telescope actually measured the composition and found just 4% by mass water.

I was attacked when I said it's probably not real that these teams are reporting things, but they are not real, even though they made press releases.

But then Webb demonstrated that it's only 4% by mass.

So that proved my point, even though I was not a member of those teams.

So it's 4% by mass water.

And then the question is, is there any dust?

If there was dust particles that are...

half a micrometer in size, roughly the size of the wavelength of visible light.

These kinds of particles scatter sunlight very effectively.

If that was the case, you would see them being pushed, those particles being pushed by radiation pressure from the sun to trail the object from behind it away from the sun.

Why?

Because they're being slowed down.

The object is approaching at some speed.

They are slowed down so that then you end up with

you know, a tail going away from the sun.

And that's what you see in comets.

There was no evidence for that during July and August.

Now in September, it seemed to have reversed from being an anti-tail to a tail.
