Lightyears is yet another UNPROVEN scientific theory, when one looks in a telescope at an image it is in real time and nothing exist to prove otherwise, just think of the ill-logic the image is not really reality, there is no looking into time by looking at the galaxies, IMPOSSIBLE!

The light year is NOT A THEORY, but a measure of cosmic distance, which is close to six trillion miles.
Light has been measured by precision instrumentation to travel close to 186,272 miles per second.
3.26 light years equals one parsec, which is the base unit for finding stellar distances through parallax, using a base measurement equal to the diameter of Earth's orbit around the Sun (186 million miles).
The light that defines the Andromeda galaxy (M31) to our eyes, left Andromeda 2.5 million years ago. What we see now is what M31 looked like 2.5 million years ago.
What's impossible about that?
Not only does this make no sense, there's irony is this one's capitalazation pattern.
Think about it. He/she capitalized 'UNPROVEN' and 'IMPOSSIBLE.
Think about it.
Complete (and probably deliberate) misunderstanding of the whole concept. This deserves to be kept at a solid 5 rating for at least 50 votes.
Brest: Yes, I think that he really is claiming that light is instantaneous. He probably doesn't even realize he's doing it, of course, but the bottom line for him is that any solid evidence that the universe is far older than 6,000 years cannot possibly be allowed.

Last year, Voyager 1 passed the 100 AU milestone, which makes it 100,000 light-seconds away...[86,400 seconds in a 24-hour day]...thus, it takes more than one day for a radio signal from Earth to reach Voyager 1.
100,000 light-seconds travelled in 30 years. Not bad.
Gleep. Divide the light-seconds figure in half, sorry...1 AU = 500 light-seconds, not a thousand.
The *round-trip* signal time is over a day.
When one looks into a glass of water with a straw in it, the straw is really bent and nothing exists to prove otherwise, just think of all the ill-logic if the image is not really reality. IMPOSSIBLE!!

Because, of course, a random yahoo in the series of tubes knows so much more about space and the cosmos and the infinite than people who consistently refined theories that have been in the works since THE SIXTEENTH CENTURY.
Is it just impossible to blow that little mind of yours? Seriously. Read up on some cosmology. Fascinating shit right there. I recommend Neil DeGrasse Tyson.
Simple, really.
The speed of light is a constant, finite number- already proven.
Constant, finite speeds take time to travel across certain distances- bigger distances equals more time elapsing.
I think this is called a "proof."
Meters are just a theory
Don't treat them as fact
“Lightyears is yet another UNPROVEN scientific theory,”
Lightyears. A measure of distance.
A measure of the distance that light will travel under observed conditions.
It’s not a scientific theory, it’s like a really simple story problem.
Light leaves a star at time zero, and travels at speed c.
How far will the light travel in 365.25 days?
One light-year.
What would it take to prove this?
“when one looks in a telescope at an image it is in real time and nothing exist to prove otherwise,”
Ah. So it’s not ‘lightyear’ you’re bitching about, it’s relativity.
This is not a true statement, though. We can measure differences in the speed of light between the Earth’s surface and satellites in orbit.
GPS has to take relativity into account or it provides erroneous locations.
Also, if you have a phone conversation with someone overseas. The signal travels at light-speed. There is a delay between what you say and how they respond, what with the distances the signal has to cover.
Also also, there’s a measurable delay in signals between orbital platforms and the Earth’s Surface. Lightspeed is not real-time.
“just think of the ill-logic the image is not really reality, there is no looking into time by looking at the galaxies, IMPOSSIBLE!”
Wow, you’re really convinced that you’re smarter than the experts who study this.
And you’re demonstrably wrong.
That makes you kind of an idiot.
Confused?
So were we! You can find all of this, and more, on Fundies Say the Darndest Things!
