Is space travel theoretically impossible?

I'm sure by now that everybody's noticed that whenever he's confronted with a question that requires a technical answer (fuelling a moon rocket) jroa suddenly disappears.  Although he often returns with some sort of totally irrelevant rhetorical question phrased as an answer.

   

Greetings!

Space travel is not possible, as the rocket would crash into the celestial dome upon which the stars, moon, and planets are fixed.  (There is debate as to whether the sun is affixed to the dome.)

As we do not know the composition of the material that forms the celestial dome, we do not know if, when the rocket crashes into it, the rocket would (a) get lodged in the dome; or (b) come hurtling back to earth, possibly causing major damage, depending on where it lands.

While I am not a scientist by trade, I am something of a Sunday scientist, and have been studying the facts in hopes of determining the most plausible outcome. 

Yours Truly,

Flatso

Because the same force that is accelerating the Earth is accelerating the sun and moon.

So why would a space ship not be able to fly to the moon?  Does this this magical force know not to accelerate man made objects?

Because of fuel supply challenges.

How did you conclude that fuel supply challenges can't be overcome?  Can you cite any calculations that show that it's not possible to carry enough fuel to reach orbit or to stay in orbit?

Things do not run out of fuel?

Not before they reach orbit.

I think you missed the actual question, which was:

"Can you cite any calculations that show that it's not possible to carry enough fuel to reach orbit or to stay in orbit?"


That's OK, I'm here to help.
