laser light will disappear in the bottle but appear on the other side instantly, only needs 1 frame to cover the event.

We know for a fact that it wouldn't. You keep ignoring the spacecraft time delays I've been talking about.

The tech is there, why not actually do a measurement? What to worry about? 500 people not 1 reply, seems very odd.

Because there's no good reason to do it.

The latest time scientists measure light speed in air was 1926.

It won't have changed much.

But you are wrong anyway.
This guy, for example. measured it much more recently.

And this depends on it too.

The measurement they use is the refractive index of air.
It's very close to 1.  (typically about 1.0003- depending on pressure, temperature and humidity as well as wavelength)
It is the measured ratio of the speed of light in vacuum to the speed of light in air.


If you were right then the ratio would be infinity.
It isn't.
So you are wrong.
Now, as it happens, I don't have much better to do with my time than point out mistakes you made  which a school student would be embarrassed about.
But the physics professors you pestered probably have.

I wrote to MIT tech camera team, suggested them to use a 3 section glass tube, water, vacuum, water connect together, filming laser pause passing through the whole tube.

You wouldn't have a vacuum if there was water there.
You would have water vapour.

Find out truth is a good reason.

For example, you say gravity speed is light speed. I say gravity is instantaneous. Who is correct?

All forces are coexist with matters, attracting or repelling all the times, therefore infinite speed. Simple FACT. 

If gravity is light speed, it will be delay all the time, no planets can have stable orbit. This is simple FACT.

If LIGO can detect gravity wave from 1.3 billion years ago, why can't LIGO detect CME or earth quake?

The glass tube has 3 sections.

It's already been found out. Signal delays from spacecraft show what it is. It isn't infinite.

There is an easier way to win a Nobel Prize by proving light is not wave in vacuum space.

If you knew anything about practical science, you would know that this experiment is done  many times every day.

Short wave ultraviolet light is absorbed by oxygen in the air.
So, equipment used for measuring short wave Uv is set up in vacuum chambers.
And the equipment usually uses diffraction gratings for wavelength selection (because prisms also are opaque to short wave UV).
The part of the spectrum where they do this is even called "vacuum ultraviolet".
https://en.wikipedia.org/wiki/Ultraviolet#Subtypes


And, since we know that diffraction gratings work in a vacuum, we know that light is still a wave in a vacuum.

It's really obvious to anyone who knows about science and light.
That's possibly why the professors didn't bother to get into an argument with you.

Light is not particle, all light beam double slit experiments were done is the open air. I did my research. I suggested MIT to do it too. No reply.

Light speed in vacuum space has never been measured. The latest time scientists measure light speed in air was 1926.

I suggested them to use MIT tech to measure light speed in vacuum glass bottle, hope someone search for the truth.

MIT had a video show off their trillion frame camera filming laser pause passing through a water bottle, in very slow motion.

Use same technology they can easily measure light speed in a vacuum glass bottle, I wrote to the tech team, they didn't reply. Don't understand why. 

Probably because they get hundreds of such emails from assorted loonies..

[Bored chemist]

all light beam double slit experiments were done is the open air.

As I pointed out, that's simply not true.

Related phenomena - which depend on diffraction are also found in the vacuum chambers use in semiconductor manufacture.

[seeker3 (OP)]

The first 1 to do a double slit experiment in vacuum, can prove there is no light wave in vacuum space, win a Nobel.

If you have the access, you should take this golden opportunity.

Put the slits and screen on the walls of a square glass container. Point a laser beam on the slits, video the light wave interference on the screen. Then vacuum the container, video the interference disappear and left two bright lines on the screen as if light act as particle. 

In fact, light is not wave nor particle, light is vibrating electrostatic force carry by vibrating electrons/atoms.

I cannot find any video of double slit experiment done in vacuum, please show me what do you have. Thanks!

According to them, no.

Also, do you understand what the word "typically" means in the question "Is the double-slit experiment typically carried out in a vacuum?"

That will be because it will have been done so long ago that there were no video recordings.

youtube has 10's double slit experiment, all done is air. Care to take a look?  38.38

[Bored chemist]

Yes.
So what?
