cons: You can never come back.

pros: We could send liberals.

the only way meaningful space travel could be possible would be to slip in and out of another dimension where time does not exist

and transplanting the seed of humanity among the stars...

What did the stars ever do to us to deserve that fate? :)

In the meantime, there’s a whole group of folks in San Francisco that are desperately figuring out how to get to Uranus.

Popular Science had an article on interstellar travel in this month's issue. From what I read, being stuck on a spacecraft for your entire lifetime would be a hard to take mentally. If anything broke down, there better be replacement parts.

while [FTL] remains entirely theoretical at this point

No, it does not. You will find NO theoretical physicist who believes that it's possible. Saying that we will someday find a way to travel faster than the speed of light is EXACTLY the same as saying "someday we'll find a shorter distance between two points than a straight line."

No. We won't.

The geometry of the universe is what it is, and so many phenomena from intrinsic spin to antimatter to mass energy equivalence to time dilation to Lorentz contraction to things as simple as the color of gold, ALL are a direct result of relativity.

There is no shorter distance between two points than a straight line. Period.

Before people traveling to other stars happens the solar system will be well populated. At that point the occupation of other planets and moons by people would be routine enough to make a star voyage a realistic goal. I don't expect it to happen any other way

[faithhopecharity]

how to get to other stars and galaxies... has been known for a number of years..... we don’t have to pay tons of our tax money to research the question...

They’d also have to figure out a way to create artificial gravity........

[I want the USA back]

Dimensions are not places where you can go. There is no “fourth dimension” you can slip into to avoid the laws of physics.

Flux capacitor as a power source would do the trick.

Another “Scientific” idea that makes Infinity Wars look like a documentary.

[Seruzawa]

I don’t think that physicists, who are madly seeking undetectable phenomena, are going to solve the FTL problem.

world ships capable of supporting multiple generations of travellers (aka. generation ships),

Fine for the first generation of trained crew eager to leave Earth, but what happens when a quarter of the crew are three-foot tall entropy monsters. "You let go of the airlock knob. Let it go! You'll get a spanking if you turn that an no one will hear you scream."

[Rinnwald]

It would suck to be an early star explorer, get there after many years and tribulations, only to discover people with newer tech beat you there.

As Heinlein noted, settling the Solar System will be like any of Earth’s Great Migrations, “The cowards never started, and the weaklings died on the way.”
