Sailing

[Amianthus]

I'm still amazed that members of the starship enterprise never turn to liquid goo, in the rear of the ship, every time they go into warp.

The artificial gravity generates an inertial compensation. This was explained a few times.

Not enough to my satisfaction

One of the experimental techniques for withstanding high acceleration is to submerge a person in a tub of salt water.

Extremely high accelerations produce only mild effects because of the compensation of buoyancy.

If a person is immersed in liquid it doesn't matter much whether the tub is large or small so one of the most sophisticated experiments places the body in a tub shaped like a suit ,jointed,wearable but full of liquid.

Even higher accelerations could be endured if a person were immersed in liquid , had his lungs filled with liquid and the entire compartment he was in was pressed up with liquid, no bubbles. Even hundreds of G would be no problem.

So for the fighter pilot of the future , perhaps the astronaut of the future, the way forward is regression to the womb.

What fighter pilots of the future? You mean the guys at the game consoles who pilot the drones?
Fighter pilots of the future are like the elevator operators and horsecar conductors of today. As in nonexistent.
I am sure that the Airforce will mourn the day that planes need no pilots, just as the cavalry mourns the loss of horses for purposes other than funerals. Perhaps they will keep the Blue Angels around like Budweiser has its Clydesdales.

===============
Theoretically, a constant force from the lightsource will cause the solar sailed ship to accelerate. But of course, all flight is away from the solar course, and the force exerted by the light decreases with the distance, I think I read with the square of the distance.

There is also the speed of light, which nothing can surpass. In any event, it seems quite unlikely that a light-propelled ship could travel faster than the light propelling it.

That is the current thinking , that fighters can be drones , cheaper , more versitile , able to handle greater G force. A lot of money is being bet on this tecnology being the winner.

Still it probly isn't useless to learn new wys to fortify a person against G force.
===============================

There is no potential for a solar sail to acheive greater than speed of light speeds. There is not even any realistic expectation of one quarter light speed. The faster the sail goes , the less accelleration it will be able to harvest from the light that drives it , it will also be further from the sorce of light with each passing moment further reduceing the availible power.

Still the speeds that a solar sail probly can acheive are higher than the potentials of any other spacecraft we are presently ready to build. It might be able to carry a small probe to nearby stars in a small number of centurys.
