Don't recall hearing that anybody read about that in the "BOOK" though !

Maybe it is our purpose in the universe to develop space travel so we can spread the Good News?did jesus visit all 8 billion planets in our solar system to save the aliens one at a time?
Of course!did jesus visit all 8 billion planets in our solar system to save the aliens one at a time?
After all he created and loves them all.....:angel:
Not sure about Jesus but Noah certainly visited all the planets to put all of god's creatures on his ark.did jesus visit all 8 billion planets in our solar system to save the aliens one at a time?
I'm in agreement. A single atom would likely pass right through the empty space in all the ships atoms. I'd be interested to see the math for the likelihood of a small asteroid being hit at that high a speed. I am guessing that even a small chunk might just be lucky enough to pass through because of the probabilities involved in quantum tunneling.I think what you read was something like one tiny asteroid of a size of 1 cm in
diameter. .
As for radiation, I'm sure that between physical shielding and an artificial magnetosphere we wouldn't have problems.
Gee, I could have sworn this was already discussed in this thread.The findings also raise a blaring question, Marcy said: If we aren't alone, why is "there a deafening silence in our Milky Way galaxy from advanced civilizations?"
...
Answer: distance involved means huge time for the signal to travel and power loss.
Actually it's just the radiation that seems to be the problem and as I said in an earlier post, that can be resolved. Low g might create problems but we have no real idea how it would effect development. As a guess, a space-born baby would not have the structural strength to live on a new planet but could function fine in space and since it's not a genetic change the 1st generation raised in normal gravity would be fine.So far conception can only occur with the gravitational field found on the earth's surface, making reproduction in outer space impossible.
Biggest problem I see is how to manage the social interactions so the people wouldn't just kill each other off.
Yeah, this is the big problem. We are close in technology to solving all the other problems for a relatively slow ship.Biggest problem I see is how to manage the social interactions so the people wouldn't just kill each other off.
This is why I think sending frozen embryos and some sort of child rearing computer is the way to go. Only one generation to social engineer.
I remember reading as a kid, a Time Life book about the universe and that a 26 year one way trip (or was it a 52 year round trip) to the Andromeda Constellation at the speed of light would mean that a million years or so would elapse here on Earth.Not even close. Special relativity dictates that time will dilate, meaning that as you travel faster, it will take less time in your frame of reference.
And the fact that these journeys may take a long time in no prevents them from being attempted, so that's no quarantine.
So it may not take generations at or close to the speed of light (depending on your destination of course) but it certainly would be if your travelling at speeds limited by our current technology.
You think we don't have it right yet.Until we have a definitive explanation for how life formed on our own planet, it's impossible to determine the likelihood of there being other life out there even knowing the number of planets in the Goldilocks zone.
Read Andrew Knoll, a Harvard professor and author of Life on a Young Planet: The First Three Billion Years of Life. or watch the Nova program on the same.

There is still some things to learn, but we've got quite a grasp on more than the basics.

I tend to agree. So a few elements, water, warm atmosphere and a bolt of lightning, right?
Biochemistry is not my long suit, but it's little more complicated than that, yet basically yup. The Hadean Age, ~4.5 billion years ago was an amazingly interesting period and was the jump start for the chemicals for life on earth, Carbon, Oxygen, Nitrogen, Hydrogen, and Phosphorus with the first forms of life appearing ~3.75 billion years ago. Photosynthetic life began ~2 billion years ago and so on.I tend to agree. So a few elements, water, warm atmosphere and a bolt of lightning, right?
I've been using it as an alias for so long, I almost forget. I think it's from a book series I used to read when I was like 12 years old. I can't remember what it's called.Rhuarc what is your name from?
If that is so, I guess the question becomes: how many of those 8.8 billion planets have the same conditions as Earth did those 3.5 some-odd billion years ago?You think we don't have it right yet.

Ask Fonzie, he'll know of certain.If that is so, I guess the question becomes: how many of those 8.8 billion planets have the same conditions as Earth did those 3.5 some-odd billion years ago?
I bet you mean 'stopping'?Not necessarily. You can accelerate to ridiculous speeds, even using current technology. The acceleration isn't a big factor - current technologies are far more limiting in other areas.
