I always wonder when we will see a spaceship with gravity and magnity field built-in. I don't know if the technology is too deep for our current scientist and engineers. What do you guys think about it? I think if we are able one day in the future to built one (in 100+ years) We will be able to travel far and far away without the risk of cancer or any health issue that currently affect astronauts.

Just send heavier astronauts and they'll have their own gravity field.

Maybe in 100 years.

 

By the way, NASA and other Military persons, know how gravity works, now.

 

Another piece of Technology being suppressed.

Yes, it's scary to think they could turn off the Earth's gravity at any given notice and we'd all float into the space.

Outside of sci-fi novels, humans can't generate gravity fields, we just don't know how gravity works (Outside of more mass = more gravity, but you're not going to see spaceships with enough mass to have 1g)

Gravity is doable in theory, but it's not really feasible without significant spacecraft size because the craft has be large enough for centrifugal forces to be relatively even in habitable quarters (i.e. the forces can't vary widely in the distances between the ceiling and floors otherwise you'd feel as if you were spinning (and vomit everywhere)). So if you think in terms of earth, we don't feel like we are spinning because the centrifugal forces are relatively even all around us. So I'd say it's probably more a question of practicality and engineering than of discovering the science. Unless of course, science comes up with other simpler means to do it at some other point.

 

Why generate a magnetic field though? What does that gain you here?

We could build a magnetic field to protect us of solar winds and any other menace in space while traveling to other worlds.

 Want a nation gone? turn off gravity at that location lol.

I think the most pressing concern now is developing faster means of transportation. Microgravity isn't too bad if you only spend a few days in it.

For what possible reason?

Stuff like solar winds won't hurt you, and a magnetic field won't stop stuff like micro-meteorites or radiation, for that you need better shielding.

I saw a documentary where they discussed a hypothetical situation where we had to evacuate earth and live on a space ship for a long time while en-route to our new home.  They simulated gravity by making the whole ship rotate at a specific speed, and because it was so large, the people wouldn't necessarily sense the movement, but the centrifugal force simulated gravity so people would feel normal, and even plants could use it to grow in the proper direction.

We can control gravity? Proof!

Because far as Im aware we can`t. We have a basic understanding of it and how it fits into the standard model of things, but we cannot control or bend it. Not least in any way I can think/know of.

If we could there would be far reaching consequence and implication of its use today, now!!

Hell far as Im aware we don`t even have any super dense objects or pieces of material from space on Earth to study.

All I can say for sure is that we only know about how gravity in theory works, i.e the basic mechanic and how the size and density of an object is what creates a gravitational field. We dont know what and how to manipulate the matter in such a way as to create gravity. Least not that I know of. And we certainly couldnt turn it off!!

Artificial gravity

 

Methods for generating artificial gravity

 

Gravity can be simulated in numerous ways:

  • rotation
  • linear acceleration
  • mass
  • magnetism
  • gravity generator/gravitomagnetism
