Why Did We Get Into Space

Granted, but, for example, Ariane is 40:1 fuel: rest of it.

You think there won't be volunteers?

OK, here's an idea--we send out a ship to world that's 100 light-years away; the ship travels at 1/10 the speed of light, and will take 1000 years to get where its going, so they aim at where the star will be in 1000 years time, and plot their course accordingly.

100 years later the technology has advanced to the point where ships can travel at 50% of the speed of light, and one such ship goes out to the same star. The crew aim the ship at where the star is going to be in 200 years time, and plot their course.

They could deviate their course to pick up the crew and passengers of the first ship and help them get to the star-system in the shorter time.

Anthropics. If this is the case, then why send a space ship in the first place?

And another thought- what happens if you're traveling a billion miles an hour and hit an interstellar asteroid? How could you even detect the asteroid at that speed in the darkness of space?? What if you're going 90% the speed of light and hit a hydrogen atom- would it blow the ship up???

 

Can we all agree that colonizing another Earth would first require a huge leap- either in speed or in human physiology?

The closest thing to an answer I can give is that since spacetime is warped and twisted, if we could build a ship that goes straight from point A to B regardless of the flow of spacetime. In theory, that would make a 10 light year trip a whole lot shorter.

 

Lots of good questions jmpet. Try to answer some of them for us so we can review the calculations.

 

Anthropics?
Why send a ship?
Because we want to, because we can...
Monkey curiosity.

Interstellar asteroid?
Meh, I get the point - er, tough luck?

Well by the time it was detected it would probably be too late.

One more problem to be solved.

A fairly large leap at least.

Except that those theories are even further away than the engineering of a large sub-light ship.

 

Why did they go to the moon and what did they find

Google video Richard Hoagland

well worth a look

 

Only if you're a fan of out and out cranks.

 

Hoagland is a crank. If you want information on him go to Bad Astronomy where crank ideas are exposed for what they are.

It has nothing to do with human dreams . It has all to do with military reasons including international espionage .

 

Nonsense.
Military reasons didn't motivate Goddard, von Braun* or Tsiolkovsky.

* Meh, the military provided funding for him at least. The others tended to be ignored.

 

Sure enough when I see non sense I know non sense .
Military reasons and international espionage are behind space exploration for sure .......

Clueless too...

 

I just realised, cosmic hasn't been around for over a month. Does anyone know if he's alright?

 

Those specific researchers might not have been personally motivated by "military reasons," but the projects that they worked on that actually resulted in working space vehicles/travel most certainly had military motivations.

 

Why did we get into space?

It was all there was and was all around "us" before the big bang; when the big bang did the boom thang, and we showed up down stream from that, still space was the only thing all around us still, and space was the only place to go when we fell off the edge of "da oit" ...

 

And that's why NASA is a civilian organization. And most of the launches send up civilian satellites for weather, civilian broadcasts such as cable junk, solar and planetary studies.

Clueless? You betcha!

 

Huh....you are clueless....I am not surprised in the least.....:roflmao::roflmao:.

 

Any proof of this? I doubt it. Just a glib meaningless comment. When you have no proof please take the time to state a disclaimer such as this:

"This is a meaningless, unsubstantiated claim for which I have no proof, but my internal political demons make me spout this nonsense."
