Anything that you scoop up, unless it is travelling at the same velocity as you are in the same direction, would entail a transfer of momentum which would affect your ship's velocity (and potentially direction.)

The change in momentum part is dead on - made up or not!

Re: Closest non solar planet
That is the Bussard ramjet system. Obviously designed by Professor Bussard.JimC wrote:I have read speculation about using intense magnetic fields to gather the charged particles in the interstellar medium. If the field was big and effective enough, perhaps the gathered particles could be used as reaction mass... As a side benefit, they aren't crashing into the spacecraft...
Sadly, it won't work. After Bussard did all the work and got lots of people excited, another academic party pooper came along with more advanced calculations and showed that the magnetic field involved worked much better as a brake than as a source of energy. In other words, the magnetic field slows down a star ship, which kinda defeats the purpose.
For every human action, there is a rationalisation and a reason. Only sometimes do they coincide.

How come my guesswork never worked like that in the bookies?

Re: Closest non solar planet
We can already do near that with today's 1960's technology. Project Orion nuclear powered craft (by riding nuclear explosion blast waves) would require about 36 days of 1g acceleration to reach 10% the speed of light.Blind groper wrote:Agreed.
There was a Scientific American article about 10 years ago, written by a couple of NASA scientists, who predicted that, within 500 to 1000 years, humans could build a star ship capable of accelerating to between 0.1c and 0.2c. That would do it.
A rational skeptic should be able to discuss and debate anything, no matter how much they may personally disagree with that point of view. Discussing a subject is not agreeing with it, but understanding it.

No Orion craft has ever been built, so we actually do not know that.
