Sceptimatics theory

Can someone (hewho) please post a video showing light propagating in a vacuum?  I cannot seem to find one anywhere and yet many keep mentioning it and that is supposedly how the speed of light was determined.

Anyway, three questions for scepti.

1. How do you explain galaxies moving away from us?
have you seen this happen or are you going by what you are told and also, how do they calculate this?

2. If nothing can exist in a perfect vacuum then how does earth exist inside this vacuum?
Because earth expands all its matter until the last of that matter becomes zero pressure and freezes , creating a cell in suspended animation.
3. I have seen references to a reflected sun and moon. Can you explain this please?
The sun is reflected onto the ice dome from the central part of earth's circle and back to earth and reflected again, only with much less strength, IE the moon. All this is achieved , along with what we see as stars, through vibrating crystals on a scale that would make women drool at the mouth for eternity.

The father and coins in a vacuum tube show light propagating in a vacuum since you can see them perfectly.

1. Have you seen Australia, deep sea fish, a platypus, etc. or are you just going by what you have been told? Also research the doppler effect.

2. But that means that there is matter (something) inside your vacuum when it is impossible for there to be anything in your vacuum. Whether it is in suspended animation or not is irrelevent.

3. Explain the phases of the moon then. And why the sun moves. And sunsets. And craters on the moon.

Light is a particle cast off by a chemical reaction or by reradiation of absorbed photons and energy. It is not an 'energy'

It carries energy though.  So essentially it transforms into an energy.

I know people who live in Australia, I can see or fish for deep sea fish. I can view a platypuss. Can you directly do any of this with your shifting galaxy? No? I didn't think so.

Yes there's matter inside the cell that is inside the "nothingness." Don't get mixed up between what you think is a vacuum inside earth and what's outside of earth. Space does not exist outside of earth and the last of earth's elements become frozen against it, because the last of that element has became frozen whilst all other molecules/matter are in various states of motion/agitation.

The phases of the moon are the moving reflection of light from the middle of earth as the crystals vibrate and move around. The sunsets you see are the result of the reflection off of the dome and back to the other side of the dome, so when your reflected sun is near the top of the dome on one side, it's reflection is down below or at the bottom of the dome on the other part of the circle.

There's the moon landing videos, the ISS external videos, any video showing the effects of vacuum pressure inside a glass dome, etc. I think a few have been linked in this very thread.

Nothing from NASA.  I mean amateur or physics demonstration videos.

The speed of light has been measured in many different ways.  Here is light travelling in (super super) slow motion though; I think this is through water, so not in a vacuum.  Slow motion video of light propagating was only recently achieved, and so I expect most of the video on the internet will be this sort of candy video:

Obviously water is much different from a vacuum.  I'm starting to think there is no evidence for this.  Therefore, no limit to the speed of light.

Well, light is propogating through that vacuum. Otherwise you wouldn't be able to see the feather and ball bearing.

here it comes Alex... you know they will say that it's not a perfect vacuum. A perfect vacuum only exists in space and they've seen this with their own zetetic eyes.

A vacuum which simultaneously cannot contain anything and contains everything we know, yeah. Don't even know why I bother anymore.

Show me where my logic fails:
*The vacuum has nothing in it.
*The earth is in this vacuum.
*The earth is something.
*Something is in the vacuum.
*Point 4 contradicts point 1.

Ok so you are saying that scientists have determined the speed of light by simply observing a near-empty vacuum inside a lit room?

Where in the sentence you referenced does Alex say scientists determined anything quantifiable from merely observing light in a bottle?

THE SPEED OF LIGHT
"It is the speed at which all massless particles and associated fields (including electromagnetic radiation such as light) travel in vacuum." - Wikipedia

How did they determine the speed of light in a vacuum?  I wanted to see light in a vacuum and two people here mentioned light being propagated indirectly in a vacuum.  I don't see what is so hard to understand here.

Well, back in the day some fellow noticed Jupiter's moons' periods varied. That is, sometimes they seemed to go faster, others slower. Takeing careful measurements, he figured that light moved about 220,000 km/s.

Slightly more recently astronomers used telescopes and the apparent positions of stars. They noticed the stars seemed to wobble a bit. One fellow measured the wobble and calculated that light moves about 10,000 times faster than the Earth.

In modern times, we regularly measure the delay between various spacecraft. With so many robotic probes, satellites, etc. out in space, we can measure whatever distance we want as often as we want.

One can also set up a cavity resonator, in which a light of a certain wavelength will resonate. If you know the size of the container and the wavelength, you can calculate the speed of light. This is easy to do in a small vacuum.

My rebuttal to Alex showing light propagating in a vacuum with a feather and ball bearing is this:

I asked to see evidence of light in a vacuum.  Not light outside of the vacuum and with objects inside it.  The objects alter the result of the speed of light and the light source was not completely inside the vacuum.

1. The light speed changes due to travelling through the glass.
2. The light speed changes due to the feather and ball bearing inside.

So unless I see a light inside a near-empty vacuum...that means IN A DARK ROOM, the whole definition of the speed of light "inside a vacuum" is not considered evidence.  It MUST be replicated ON EARTH.

Firstly, all you asked about was for evidence of light propagating in a vacuum. This was provided for you. SEVERAL TIMES NOW.
You did say you had heard this was how the speed of light was calculated, but this wasn't part of your request. ALL you asked for was for evidence of light being able to propagate through a vacuum.

Firstly, we can measure the speed of light in multiple mediums, as the slow motion video of light travelling through the soda bottle demonstrates.

Secondly, we have observed light travelling through many different mediums. We know how it reacts in vacuums, near vacuums, glass, and air. The removal of air from a container does not affect the ability of light to propagate, whereas the same DOES affect sounds produced inside the same container. This was to explain that light is not sound.

Thirdly, why do you associate dark room with vacuum? Is that just so the light can be more easily seen? The speed of light can be measured in a vacuum chamber via non-visible radio waves as well.
