Weightlessness kills cancer cells?

Every horizontal axis centrifuge goes through a specific cancellation of the terrestrial field on its upper part ...

It is not rather in the descending phase?

Gravity is the state of a system in which no acceleration, caused by gravitation or any other force, can be measured by an observer in the system in question1. This includes free fall situations, but also situations where the system is far enough away from any source of gravity that it can be overlooked. This situation results in an absence of weight (but the mass remains unchanged). fr.wikipedia.org/wiki/Impesanteur

To simulate free fall, constant acceleration is required throughout the downward phase to cancel the weight of the test pieces. With a stepper motor to manage in PWM it must be possible.

On the other hand "to make them rotate until they feel the feeling of microgravity", I do not see too much. In the image provided we see a box with gears and tubes inside. ?

In sufficiently salty water, your mass is the same but your weight can become zero (as in space).

Do not confuse gravity and buoyancy.

Probably, the pivoting of the tubes is synchronized with the rotation of the assembly so that each particle contained in the test tubes is in "free fall" almost permanently ...

Yes perhaps to counter the centripetal force, but always in the downward phase.

In the ascent, countering gravity is inevitable.

Yes, but only if you turn it over or look backwards!

And in front of a mirror.

There is no solution to cancel gravity, except on earth the parabolic flight or the free fall, but then it does not last long, certainly too little time to have a significant effect on cancer cells.

On the other hand, there would be a trick to compensate for the effect of gravitation at the atomic level, therefore also molecular, it is an extremely powerful magnetic field (> 15 T), which will generate a magnetic force opposing gravity. But this only acts on diatomic materials, of which fortunately water is part, which made it possible to levitate a frog and could make a human levitate (question of enlarging the area where the field operates):

Do cancer cells contain water or other diamagnetic atoms / molecules? If yes, then it could be an effective way to bluff them because unlike pseudo-levitation by immersion and the force of Archimedes, there it is at the molecular level that the compensation is done, the force on each atom is canceling. I don't know if these researchers have thought about it ...

Great idea, the magnetic fields, and then "it's safe" ...

Magnetic fields are harmless. Standards have been established to reassure populations, without any epidemiological or laboratory study showing anything other than the thermal risk for high intensity variable fields (HF) that we do not have in practice, except in a microwave oven.
The disease of "electro-sensitive" is curable by psychiatrists: it is psychosomatic.

Those who mix everything and anything have not understood that here, in terms of levitation, we are only talking about a non-variable static magnetic field, therefore not inducing currents in conductive materials.
1T fields are common in commercial neodymium magnets found everywhere and no one has ever complained about anything. Going to 15 or 20T will not pose any problem, except technical because of the large volume of field required, the frogs which levitated attest it.

That said, those who are afraid of magnetic fields should refuse MRIs. They will increase their chances of dying prematurely but it is not necessarily harmful to the rest of humanity, on the contrary, the reward will even be a Darwin Award.

Tryphon stronger than EPFL scientists and researchers. There is no denying that we have plenty of it!
"It's safe".
