Jwst launches in less than 3 hours

From L2 the Sun lights up the whole Universe incl.

But nobody is perfect. I cannot see the back of the Moon from my window, only the face of the Moon, as it orbits Earth. I wonder if JWST can see the back of the Moon from L2? Any ideas?

Who claims that the Sun lights up the whole Universe? There's a lot bigger, brighter stuff out there...

I think the intent is that JWST is pointed away from the Sun.

It is ESA/NASA that claims that the Sun lights up the Universe so that the JWST can see it from L2 in front of the Sun. There is not atmosphere to prevent watching the Universe there.

That's a page regarding the Solar Dynamics Observatory. Not JWST. And even there there's no mention or claim that the Sun "lights up the Universe". Yet another example of your ineptitude in regard to you comprehending, well, just about anything. Once again, you are wrong.

No, according NASA the Sun is the center of our Solar system  and all the planets around the Sun are lighted by the Sun. I can see some planets from my window. Same for all galaxies around our Solar system, i.e. the Sun lights up the Universe. I can see many galaxies, too. They look like stars. I don't need a JWST at L2 to look for more. Why do you get so upset about people not as intelligent as you knowing everything?

NASA knows the difference between the solar system and the universe.  Do you?   Being a geocentrist, I suppose you wouldn’t.

What do you think. Earth is flying around somewhere with no purpose at all?

?? Looking out of my window on Earth, it is the center of the Solar system and the Universe. It is a geocentrist view, and I see no reason why it isn't correct. Nothing to get upset about. ESA/NASA is putting JWST at L2 and they will confirm it ... after adjusting the JWST.

I suppose that's how you designed your failed egg tanker, by just looking out your window. Makes sense.

I can't quite figure out if you even know what geocentrism is. For you, is the Sun the center of the Universe or Earth?

Re the Egg tanker it is approved by United Nations IMO but it cannot enter US ports. It is based on accident statistics. USCG does not allow it!

Re geocentrism the Earth is the center of the Universe with the Sun orbiting that center. Just look out of your window and you will see it, i.e. the Sun rising in the East and setting West.

Did you ever bother making a proof of concept demonstrator to show the safety of your design?

Heiwa keeps going on and on that you can’t orbit around L2 because there is no mass at L2 and you can’t orbit around nothing.

Apparently, according to Heiwa, the following is impossible:



There is nothing at the green point. No mass.

No, planet Earth is not orbiting anything! It is just the center of the Universe and is just rotating around itself to keep cool, etc. It is the Sun that orbits Earth, which I can see from my window. I have a great view of the Mediterranean Sea from there, where the Sun rises every morning at the horizon.

Is the Earth rotating?
Is the Universe infinite or finite?

Yes, Earth + atmosphere is rotating 360°/24 hrs around its poles at the center of the Universe.
Universe is infinite in all directions from Earth.
Just look out of your window, and you'll see it.

So you're not really a full-blown geocentrist in the sense that don't those folks believe earth is absolutely stationary? As well, why would earth need to rotate if the Sun is orbiting it like geocentrists believe?

By definition there is no center in infinity. So how can earth be at the "center" of something that has no center?

Thanks for asking. Earth is rotating 360° in 24 hrs, so that we inhabitants on Earth can see the Universe in the sky above us without moving. Just look up on a clear night! Most astronomers agree Earth is rotating. It is why there are nights and days and so on.
The Universe is endless with no beginning nor end. Earth just happens to be in the middle of it. The JWST (topic) has left Earth some time ago to dock with point L2 in the Universe away from Earth to have a look and will confirm it after adjusting its telescope. I think JWST is complete nonsense like most ESA/NASA findings starting with asstronuts on the Moon. Like point L2. You cannot stop there and dock with it!

I have shown you objects orbiting around nothing.

Or do you, oh expert that has studied orbits for 60+ years, deny that the diagram shown is not how two given masses behave?

Is the diagram as shown impossible?

Or will you just go on about sunrises and sunsets?

There is no encyclopedia in the Med that I see. It is water.  Good for swimming in. 
But I know what a barycenter is.
A barycenter is the center of the mass of two  bodies that orbit one another in space and it is the point about which the two bodies orbit. In this case body #1 is Earth and body #2 is JWST and point L2 is the center of the two masses Earth/JWST. The Sun is far away.  Why the JWST has to lift of from Earth to fly to L2 is beyond my understanding. Please explain what orbits what!
