Fact of the Day: Ancient Light

Since the speed of light can only travel at 671 million miles per hour means that the lights in the universe we see are not recent at all. The nearest spiral galaxy Andromeda is about 2.5 million light years from Earth. Which means that the Andromeda we see is not the Andromeda of today, but rather the way it was 2.5 million years ago.

Looking at the past seems very odd somehow.

That is too mind boggling to digest. We might actually be in the dark right now and for the past 2.49999 million years. (?)

Reminds me of this wonderful quote: "When you wish upon a star, you're actually a few million years late, according to astronomy. The star is dead. Just like your dreams."

I had to read this three times to fully grasp it...this is a cool ass fact man. This must be why some theorists have posited that the key to time travel is developing the technology to travel at the speed of light.
