NASA rocket scientists have used the gravitational pull of one planet to “slingshot” space craft toward another planet. This method causes acceleration without additional fuel use. What if we could set up a system where craft were in (almost) perpetual motion between Earth and Mars, using each planet’s gravity to sling it toward the other? Such a trajectory is available, thanks to the work of Apollo astronaut Buzz Aldrin. The orbit is called the Aldrin Cycler. Unmanned explorers and astronauts could catch a cycler every 26 months and ride to Mars (or back) using a small fraction of the fuel that would be needed for a conventional mission. The cycler orbit simulation above can be seen in motion at Damn Interesting. Link

seems like magic is true.
Will not work.
So you get to double the speed by sling shooting -
since there is no friction in space, it will also take double the energy to SLOW down and STOP safely!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Same difference. You're going to be slowing down so far in advance to make it slow down - it's not like opening up the flaps against the wind to slow it down, ya know.
Plus, I wouldn't think that the human body could be strong enough to use that much energy to make such a G-force on a forced-brake slow-down, with that energy expenditure being tremendous to blow the reverse thrusters.
According to you we have never been to the moon. Get to an observatory that will let you see the items left behind, I have.
Again, close the yap and learn something other than conspiracy theories.
Unfortunately, like Space Elevators, Pinwheels, and other elegant solutions, the initial outlay is way too big and thus it won't happen in our lifetimes. Once we find a compelling financial reason to go to Mars, maybe, but even then...
