See? Here is when in your desperate attempt for reasoning, you start to make mistakes by lots. I will point your mistakes one by one.
By your own standard I suppose when you light up a match and you look at it you can't see it right ?...
When you watch a lighted match, you are watching the body, the origin of light. Remember, THE OBJECT.
...aaah wait we need the vacuum okeee...get yourself in a vacuum chamber buy a suite figure it out whatever get a lantern in there and look at it... light will be invisible in your book...cause reasons...
Stop your "thoughts experiments". I know that such is the style of dumb dudes trying to prove their fantasies. If you can't support your point with real experiments or observations, your point is void. Here, even computer simulations are invalid.
Again, you can't see light with your naked eyes. If you can see light, then you should see it passing by in front of you all the time, don't you get it?
Let me make it easier for you:
You just need a small vacuum glass chamber with a source of light in the opposite side and you on the other end. If light can't travel through the vacuum you wont see it. use a laser for that matter...you wont get any blinder then you already are don't worry.
...man you are seriously troubled...
What are you talking about? Who says that light coming from the Sun and stars is "laser light"?
And about your example, No one here says that light can't travel thru vacuum. Using a laser light crossing the chamber, is using ONE WAVELENGTH, this is to say, one color of the spectrum.
And here is when your theory fails miserably:
My examples are easy to be followed. You just need to pay a movie ticket to do the following experiment which will imitate the monochromatic light similar to laser, and you will find out that your theory is nothing but crap to the square.
1)- when the movie itself didn't start yet, there are several ads of different products. One of the ads will allow you to see on the screen a similar scenario:
a)- Red color at the bottom left,
b)- Green color at the bottom center and right side of the screen.
c)- Light blue color at the middle level and top of the screen.
2)- Stand on the screen area and walk to the red zone. Look directly at the PROJECTOR. What you will see is an intense red light point at the center, and you will see the red light reflecting on the flowing dust of the theater saloon.
3)- Stand on the screen area and walk to the green zone. Look directly at the PROJECTOR. What you will see is an intense green light point at the center, and you will see the green light reflecting on the flowing dust of the theater saloon.
4)- The same will happen when you stand on the screen reaching the light blue zone of the screen and from here looking straight at the PROJECTOR.
You will notice that you won't see "any image" but a hurting color light hitting your eyes.
5)- Located yourself on any seat of the theater saloon. At this time, you will look at the PROJECTOR is an indirect angle, where the light beams from the projector are not hitting DIRECTLY to your eyes.
Here is when you can see not only the three colors coming from the PROJECTOR but also you will distinguish the IMAGES of the 35 mm film.
7)- You will notice with this naked eye experiment how capable you are to see an image based in light 'perception" arriving directly to you, and perception of an image with light reflecting on a body.
In this example, even when you can "see" the color light reflecting in the dust particles, you are capable only to see the source as an intense point towards you. Same happens when you see the Sun with naked eye due to the intensity factor involving the phenomenon.
But, looking at the source of light indirectly, out of the light beams, you can see the images of the source.
Now well, using filters -which is beyond of naked eye perception- you can see a clear image of the Sun.
But, why you are capable to see the Sun?
It happens that the continued nuclear activity causes the emission of light. And the light coming from such activity travels IN ALL DIRECTIONS.
This is to say, the Sun light travels to the outside and the INSIDE of the sun. This traveling of the light emitted by the Sun against itself, is what allows you to see its image, because its own emitted light hits its own surface.
This is like any explosion. When you make TNT to explode over a surface, the TNT explosion will send the force and particles towards the atmosphere and towards the floor causing a crater.
The Sun's activity does the same, sending light towards the outer space and towards its own surface or interior.
I told you that there is no other way to see objects but by having light hitting and being reflected on their bodies.
From your part, you have absolutely nothing to demonstrate the contrary.
Also, if you had a surface of 4 or 5 light years across you would experience the same apparent growth of the sun in that surface with a bigger intensity at the centre. But such surface does not exist.
Nevertheless near the sun corona one can perfectly perceive the intensity of light surrounding the sun.
You still can't get it. Review the Inverse Square Law of light. Check the size of the Sun, and its distance from us. You will notice that applying the Inverse Square Law, you should see the image of the Sun as the whole cosmos!
Can at least use a calculator and check it by yourself?
