Here is your problem you are insisting I am wrong so I am not going to argue I want you to work it out

Light from our sun does not make it 1000m down in the ocean

http://oceanservice.noaa.gov/facts/light_travel.html

Quote:

Sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet).


Star light you see from a star you see at night from a similar sort of sun is 1 billion light years away

So it has travelled 1 000 000 000 years x 365 days * 24 hrs * 60 min * 60 sec * 3E8 speed of light in space

Which is 9,460,800,000,000,000,000,000,000 meters

Attenuation is the classic physics name for energy lost in a media (http://en.wikipedia.org/wiki/Attenuation)

Quote:

In physics, attenuation (in some contexts also called extinction) is the gradual loss in intensity of any kind of flux through a medium. For instance, sunlight is attenuated by dark glasses, X-rays are attenuated by lead, and light and sound are attenuated by water.


Calculated the attenuation of space assuming it is a media for me please?

We will assume the light could go no further for simplicity and 1 billion light years in space = 1000m in water for light.

So calculate away please you have all the facts you need, if space were a media and it attenuated you then have a number and units?

So you have a simple problem you are asked to solve lets see if you answer it or post your usual dropkick stupid pictures... I have money on the later.
