Jwst launches in less than 3 hours

I am sorry that my strong flashlight didn't have the photon strength to move an object. Where can I get a stronger one?
I thought all photons are same - no mass but speed of light. Only frequency/rotation differs, i.e. mysterious heat/energy content.
But photons can physically move JWST upon contact, according NASA/ESA experts. I doubt it. Photons hitting JWST either bounce off or heats it up.

Wow, the Heiwabot really is stupid.

Lasers:

Monochromatic
The light emitted from a laser is monochromatic, that is, it is of one wavelength (color).  In contrast, ordinary white light is a combination of many different wavelengths (colors).

Directional
Lasers emit light that is highly directional.  Laser light is emitted as a relatively narrow beam in a specific direction.  Ordinary light, such as coming from the sun, a light bulb, or a candle, is emitted in many directions away from the source.

Coherent
The light from a laser is said to be coherent, which means the wavelengths of the laser light are in phase in space and time.

These three properties of laser light are what make it more of a hazard than ordinary light.  Laser light can deposit a great deal of energy within a very small area.

Your "doubt" is irrelevant.

Laser light > Photons > Move objects

Topic is the JWST in the Sun light and not photons and laser light. I see Sun light and photons from my window and, if anyone sends laser light in front of my window, i might see it, BUT, my window is not pushed away by the light. To suggest that light and photons push things away like a wave at sea is ... stupid.

You saying something is stupid means nothing. If you really think so, you may want to avert your eyes from this demonstrating how wrong you are.

Really long, but really interesting. The Smarter Every Day guy's Dad was part of the JWST sun shield team and walks him through everything about it - In the clean room with the actual JWST shield. Crazy what all has to go into this one, yet vital component.

To suggest that laser light can deposit energy on and pushing objects like the JWST with sun shields at L2 away from the Sun is simply lacking of ordinary activity of a human mind and tediously uninteresting.

To suggest that laser light can deposit energy on and pushing objects like the JWST with sun shields at L2 away from the Sun is simply lacking of ordinary activity of a human mind and tediously uninteresting.

Whether you find facts and evidence tedious or uninteresting is neither here nor there. Your bot is woefully ignorant.

To suggest that laser light can deposit energy on and pushing objects like the JWST with sun shields at L2 away from the Sun is simply lacking of ordinary activity of a human mind and tediously uninteresting.

You've already acknowledged that photons (which have momentum) can transfer energy to other objects. What do you think radiative heating is, if not an object absorbing energy from an infrared photon?

Are you trying to say Conservation of Momentum isn't a thing? That's a bold claim, if that's where you are headed, and I can't wait to see how you back it up.

To suggest that laser light can deposit energy on and pushing objects like the JWST with sun shields at L2 away from the Sun is simply lacking of ordinary activity of a human mind and tediously uninteresting.

The momentum imparted by solar photons is not in the ordinary activity of human minds.  It takes a sufficient understanding of mass/energy equivalence to properly understand the effects of those photons on JWST's sun shield.  If you find that tediously uninteresting, then perhaps you shouldn't be participating in this discussion.

Really long, but really interesting. The Smarter Every Day ...

Heiwa is completely unfamiliar with the concept of "smarter every day".

Destin is a great communicator, I really like him

Radiometer, dumb fuck . . .
I'll buy you one because I feel sorry for you.

It seems we all agree that a photon has no mass, when it flies away from the Sun at the speed of light, which I see every morning, when the weather is good, and when the Sun rises outside my window. After my having observed the photon in question, the photon is gone! It doesn't exist any more! POUFF! Gone! It didn't apply any momentum to me and my window. And same applies to the JWST orbiting L2. Many ignorant people do not understand what a photon is and that it can just magically disappear - POUFF - into nothing.

What makes you think photons don’t have mass? How did you learn that?

Why don’t you believe the same experts when they, with factual experimentation, demonstration, and calculations, show that massless photons can impart momentum on an object? The same as they show and demonstrate that photons are massless?

Why? I just look out of my window and see the photons arrive and ... POUFF ... disappear without imparting anything. Topic is JWST orbiting L2! Where are the pictures of the end or beginning of the universe??? And the holy shit ...

So we don't need any telescopes ever, anywhere, because you can just look out your window?

No, I am happy to watch the Sun, the Moon, some planets and the Milky way galaxy from my window. A telescope just enlarges objects. To see the end and beginning of the universe with a telescope incl. JWST at L2 is not possible as the universe is infinite in all directions and has always existed. Our planet Earth is in the center of it. Of course there are people suggesting the universe was created 14 billion years ago out of nothing in a big bang but there is no evidence for it. Same people just make things up, like Earth orbiting the Sun in a year. From my window I see the Sun orbiting Earth in a year and no telescope is required, etc. Just look yourself.

I'm not asking about your happiness. So now you think telescopes in general are pointless?

Not at all. Telescopes just enlarge objects in the universe as seen from Earth. Using telescopes on Earth it is easy to see that Earth is the lonely, magic center of the complete universe around us. I am happy with the view of it from my window, reason being I have a view of the sea in one direction and mountains in the back with the sky above. Only complete fools go to L2 for another look.

Radiometers do not work by light pressure (photons transferring momentum to the van) if that's what you're implying. Black side of vane heats up more; sparse air molecules in bulb are kicked away faster when they interact with black side; equal and opposite forces make black side overpower white side; vanes spin away from black side.

Why? I just look out of my window and see the photons arrive and ... POUFF ... disappear without imparting anything.

Yes, the photon did impart its momentum to you.  It's just that the amount of momentum imparted is too small for you to notice.  However, in the largely gravity and friction free environment of deep space, the constant stream of high energy photons from the sun can and will impart a meaningful amount of momentum to JWST's tennis court size sun shield.  Also, don't forget that the sun emits many photons that are at much higher energy levels than the visible photons that you see coming.

It is always my fault. I don't see and and feel the photons other people or objects see and feel at ... L2 with their tennis court size heat shields. Anyway, I look forward to seeing some JWST pictures of whatever it sees when orbiting L2. Actually my house is quite big and every morning when the Sun rises, it is hit by plenty photons at the speed of light. But my house is only heated up.
Clicking around looking for pictures of the Universe I came across :
https://www.nasa.gov/sites/default/files/styles/full_width_feature/public/thumbnails/image/colorized_wright_mons_cropped.png
Researchers on NASA's New Horizons mission have discovered evidence on Pluto for what appears to be two cryovolcanoes—volcanoes built out of frozen ice that once oozed molten ice from the inside of the dwarf planet.
Imagine what nonsense that will come from the JWST. https://www.nasa.gov/mission_pages/webb/about/index.html hasn’t been updated for years!

It is always my fault.

no shit?

. . . my house is quite big and every morning when the Sun rises, it is hit by plenty photons at the speed of light

And like a cow in the field, it's a brand new surprise.
The sun set last night, fuck, here it is again.
Total surprise.



I envy you, Hiewa.
Bathtub is the Mediterranean, oatmeal is caviar, internet is carnivorous.


Hahaha, I actually salute you.   

I think you're awesome.   

On a clear and dark night sky (no light pollution) an observer with good eyesight might see around 2000 stars. That's an entire field of view. Out of a window, you might be limited to a few dozen stars.

Telescopes in space aren't affected by daylight or weather events. They also have an entire field of view and they can see not just a few thousand stars limited to a small area around Earth, but almost every star in our galaxy and many galaxies beyond our own. And exo planets. And even the composition of other stars and planets. And nebulae and other anomalies and looking back to a time just after the birth of the universe.

Heiwa might be content with the few dozen he sees out his window and I'm sure Heiwa and his limited intelligence gets a real kick every time he sees it but it there is so much more to see and learn.

You could get the worlds brightest minds and teachers and try to explain science and the universe to a budgerigar. It still wont learn anything because its mind is too small. Heiwa is the same. No matter how much information you tell him it will never sink in. His mind is just too small

I can see plenty stars from my window but not the end of the Universe behind them, because the Universe has no end. Only idiots and asstronomers look for some God or whatever in the sky using the JWStelescope orbiting L2. What to do? Study your self! You are a human with no idea, who put you on Earth and how you function there. It is  mystery magic. You haven't got any idea, why you are there! But there are plenty professors and preachers and doctors, bla, bla, knowing it and everything else. And you believe them. I just laugh at you and them. Why waste time with such idiots?

I can see plenty stars from my window but not the end of the Universe behind them, because the Universe has no end.

If the Universe has no end, Earth can't be at its center because there is no center at which to be.

I can see plenty stars from my window...

But can you study them in any meaningful way?
