If this is one of those "Wow, the universe is so freaking huge" things... I knew that :D
I watched Carl Sagan sever times...

Carl Sagan
n. (1934-1996) United States astronomer and writer who discovered that the surface of Venus was hot and noxious in an abnormal manner and researched the possibility of extraterrestrial life

If there is something more out there, he must know by now...

Oh btw... I always always have felt insignificant :sqconfused:

edit: I hate it when I omit entire words in a post...

Yep, Carl Sagan is one of my favorites. It's too bad he died.

The Universe is just too big to fit into that little Youtube window. :sqwink: :sqbiggrin:

Sort of like self loathing?

I don't know about you guys, but I think my favorite part was where they showed just how far the first radio signals by man have traveled in space

Yeah that was cool, it makes me think that in relation to the size of just the known universe, the speed of light is actually slow, but it is still much faster than the human mind can even comprehend.

Robert Zemeckis does a great job depicting the transmission of radio waves in the movie Contact based on a Carl Sagan book.

Yes, he does, with the exception that his time scale is off a bit.
He's breaking out the 70's music as we're passing Mars.
In reality, Mars is only 5 to 20 minutes away for a radio signal, depending on our position and Mars' position in our respective orbits.
Even Pluto would be measured in hours, not decades.

I believe the reason that the human mind cannot actually comprehend 186,000+ miles per sec is due to it's physical size in relation to the distance light would actually travel in that time. If it were possible, and our bodies were, let's say, half the size of that distance, I think we'd have no trouble comprehending that speed.

It takes light from earth 322 minutes to reach Pluto at our closest orbital positions.

I think that the perspective reasoning can conversely be applied to why we don't get dizzy at the speed we are traveling due to the speed of the earth's rotation while simply standing still.

I read somewhere just recently that radio signals from Earth have passed star systems that we are only now discovering have planets roughly the size of Earth.

While unlikely, wouldn't it be interesting if our radio waves had reached some nearby aliens. By the time we located them, they might actually understand English. We could set up a forum to have discussions about Life, the Universe and Everything. :sqerr:

I saw a very interesting episode of Closer To Truth last night on PBS entitled What's the Far Future of Intelligence in the Universe? It's said that non-biological intelligence on this planet will far exceed all the biological intelligence combined in just a hundred years.

That video isn't available on the web yet but here is an interesting one entitled How Vast Is The Cosmos?
