Prometheus

FTL is going a bit off topic but……I’m familiar with warp drive as you explained it, it seems to me that is how Star Trek explained it.  I’m not so sure about that in reality, would love to see a paper explaining how in theory it would work.  Worm holes might actually exist but from what I read (can’t find it on a quick google search) it would stretch out anything that went into it into a long long string ripping apart the molecules if not atoms.

The reason I suspect it is not possible for FTL space travel for complicated things like life forms is that we are not seeing it.  If a civilization in the universe could, then with a growth rate of 1% a year the population doubles every 70 years or so, lets say 100 years of ease of calculation.  Life has probably been possible in the universe for 10 billion years, life on earth is roughly a few billion years old.  So you would have the population doubling 100, 000, 000 times.  Even if it took not 100 years but 10, 000 years to double the population then the doubling would occur 1, 000, 000 times.  Suppose the first FTL civilization occured not 10 billion years ago not 1 billion years ago but a mere 100 million years ago and took 10, 000 years to double.  You would double the population 10, 000 times.  So lets say the population started out as a single being.  Well you only have to double one 120 times to get a trillion trillion trillion beings.  That is only 120 times, it could double 10, 000 times easily, so where are all the aliens?

@MrMalachiCrunch:

so where are all the aliens?

To which there are a number of theories, namely Earth as a Zoo (aliens know about us but due to our backwardness only keep an thing on things), or that advanced civilizations are extremely rare (due to a number of necessary factors required, such as mineral rich star systems, surviving asteroid impacts, etc.) and would be separated by time and distance (two civilizations would have to develop on the same area, at the same time to achieve contact).

would be separated by time and distance (two civilizations would have to develop on the same area, at the same time to achieve contact).

Only if a civilization had a finite existence or did not expand exponentially as humans do AND avoided contact.  In 1000 years I don’t think it beyond reason to assume humans could achieve 1% the speed of light with robotic self replicating space ships carrying human DNA that could be defrosted and artificially incubated to start a colony around a new star system.  In a matter of 10 million years humans would be around every single star in our galaxy.  At least we know there are no expansionist civilizations any where in a galaxy near us.  If these ships could replicate once every 10 years then in a matter of a century and a half there would be more ships than stars in the universe.  At that rate of growth, in a few 1000 years there would be more ships than sub atomic particles in the universe so obviously the growth would reach a limit of the entire universe;s available materials would be converted into ships and humans given infinite speed.

Yeah, but in that case why hasn’t an ancient older civilization done it so already as you asked?
From there you can conclude either that a) there are/have been already galactic civilizations, and they either are too far yet, have died or are ignoring us deliberatly. Or b) There has never been a civilization on the universe capable to expanding outside and colonizing other stars, due to the factors I listed above.

Exactly.

Ignoring us deliberately is most likely if they do exist.

Died… Possible.  Even if we had colonies around every planet in our system, a GRB or Gamma Ray Burst 100 of light years away could take out an entire system if the beams are focused our way.  But it is a small window in time between becoming space faring as we are just now and interstellar space faring as we will become in about 1000 year assuming no breakthrough in technology like warp drives.  In a few 1000 years we ought to be immune to extinction.

Too far…  I don’t like this premise.  Given our growth rate, we ought to be in every star system in our galaxy in 10 million years.  10 million years is a rather short time in galactic history.  Had the dinosaurs not been wiped out 65 million years ago, the raptors may in a few million years evolved intelligence required for space-faring.  Had they done this 60 million years ago they ought to have reached every star in our galaxy assuming they could get to 1/2 of 1 percent the speed of light.

Here’s a nice artice from one of the guys at SETI.

Thanks for the link, I love articles like that.

The question that he doesn’t talk about, but that the British scientist Stephen Hawking has mentioned is that, if there are aliens out there, we may not want to meet them.

For all you know… that’s exactly how Earth Started.

Could you imagine??!?!

Maybe George Lucas was right, and all those events did happen a long time ago in a galaxy far far away…

I think Battlestar Galactica had it better planned out… It has happened before, it will happen again!

So Say We All!

Saw the movie tonight and enjoyed it. It was rushed in places. But well worth the money.
