Yea, and what about this one?

I’ll make you a deal. You work out the above problems by hand. (Try not to look at the solutions too much). Convince me you understand the solutions to those problems and then I will read that paper if you still want me to. If you don’t even look at those problems then we have nothing to talk about. Surly you can do it. It is only one page and the solutions are provided. You want me to read a 10 page paper.
It can be explained by general relativity. Unforunatly, I am not sure how.
How does the more massive paricle interact with the ship? If it doesn't then then only force on the ship is the force exserted by the laser.

I originally thought Errorist would further accelerate the ions with an electric field after ionizing them with a laser. This might not be as efficient as an ion engine but at least it would allow for more possible sources of fuel. Accelerating them with a laser entirely would be just stupid. You might as well shine a flashlight out the back of your ship, because even if the laser did accelerate them it would be with the exact same force the laser exerts back on the ship.
Getting the Velocity in Vector Form
Given the equation of the [http://mathworld.wolfram.com/ConicSection.html]conic section:
a1 x^2 +a2 x + a3 x y + a4 y +a5 y^2= a 6
I worked out the [http://mathworld.wolfram.com/Derivative.html]derivative
dr/d_theta by [http://mathworld.wolfram.com/ImplicitDi … ation.html]implicit differentiation:
This is relevant because the [http://mathworld.wolfram.com/Slope.html]slope is related to the derivative by:
dx/dy=((dr/d_theta) sin(theta) + r cos(theta))/((dr/d_theta) cos(theta) + r sin(theta))
The [http://mathworld.wolfram.com/Slope.html]slope gives the [http://mathworld.wolfram.com/Direction.html]direction a body is
traveling that is following the [http://mathworld.wolfram.com/ConicSection.html]conic section.
In other words it can be used to find the
instantaneous [http://mathworld.wolfram.com/VelocityVector.html]velocity vector.
The solution is:
dr/d_theta=
a6+a1 r^2 sin(2 theta) + a2 r sin(theta)- a3 r^2 cos(2 theta) –a4 r cos(theta) – a5 r^2 sin(2 theta)
------------------------------------------------------------------------------------------
a1 r (1 + cos(2 theta)) + a2 + a3 r + a4 +a5 r (1- cos 2 theta)
quize question 6, cosider the ions o_2^-1 and o-1 in a field of one colomb per meter square. What is the force acting on each ion and how quickly are each ion accelarated?
quze question 5, what is the force generated by accelerating one oxegen ion (o-) to half the speed of light?
quize question 4, write down the equation relating the frequency of a photon to the energy of a phton.
quize question 3, qualtativly discribe the ellectrical field produced by a changing magnetic field inside a toroid.
quize question 2:
Write down Maxwell's equations both in vector form and phasor form.
Okay, quize. What is the divergence of a vector field?
Have you read much about the modern ION engine? If you haven’t you should. I haven’t so I can’t comment to much. I don’t want to reinvent the wheel. I also haven’t done the math so I don’t know how efficient you scheme is. If you want to try and design this it might be a good exercise. But to do this you are going to have to start learning the math and physics.
It would travel at the speed of light no matter what reference frame it was viewed from. However the frequency of the light would look different from each reference frame (see the Doppler effect).
It probably wouldn’t be significant. Electrons are much lighter.
You can't travel at the speed of light. Even if you had a warp drive there is probably a better way of thinking about it then FTL.
The electron is held in place by coulomb forces. It can’t stay just anyway though because it must form a standing wave.
Okay what frequency of laser would be sufficient to ionize the gas? How efficient are these lasers? What gas are you going to use? How are you going to construct the electromagnetic nosel. Possible but the devil is in the details.
So you are making a solar thermal engine. No need for the laser.
IIRC the case for mars suggested a walking habitat as a future possibility.
How long might it be classified for?
There is some interesting theory on warp drives. Who knows what the future will hold.
Slightly off topic. Well, I guess that space tug ends the hubble debate. Hubble will be saved.
