Why Don't Spaceships Have Artificial Gravity?

We've seen this done in movies right? Well, why don't spaceships have this technology?

They need to build a space ship floor made of a switchable artificial Higgs field with neutrinos and neon plasma. Everyone knows that. Also, I have no idea what I'm talking about.

why don't we just launch earth in into space?

[seesuns]

What do you mean there is no Gravity on my spaceship...

[starvalkyrie]

Sci-show space, or "Get bummed out with what an uncooperative jerk physics is"

Gravity is fake, a conspiracy by the lizard people and the Illuminati, we all know the earth is a cube. *Grabs Popcorn.

A common misconception in the discussion about simulating gravity through rotation is that the gravity has to be 9.8m/s/s in order to be useful. Surely even a fraction of that (1/3 to 1/2 G) would have great benefits vs. zero G.

Oh us silly humans and our class .9ish civilization.

[kionera]

Throw an apple to an astronaut's head. BAM! Gravity.

[marcelfilms]

If the US would spend half the money they spend on war on space they could do this all

[DinosaurEmperor]

would it have to be a disk? Couldn't it just be two pods joined by a long tube?

So when can I train at 500x time Earth Gravity

[ze_rubenator]

It's just not ambitious enough. If the station is big enough the differences from head to feet will be very low, and the speed necessary would be very low as well. You could make something much like the halos in Halo. Well, theoretically...

[ChadEichhorn]

why was the gemini test necessary? a physics 1 student could calculate how little effect it would have

[liquidminds]

Couldn't you just use a series of capsules, circling around a common center? You could Start with a small ring, but let the capsules move outwards with cables, like an elevator. You'd get a giant ferris-wheel, with separate capsule that could easily be a lot larger than 100m in diameter. 

From what I understand. The larger the diameter, the lower the difference of gravity between head and feet for each human. So if you had those capsules rotate in 500m or 1000m distance, it should technically work.

Even most sci-fi implementations of that idea use gigantic Wheels. I don't remember any implementation that would "only" be 100m in size. Even though that's quite large for our current space-programs, it kinda isn't if you think about space-stations and interstellar travel.

I object! The Enterprise's gravity generators are not invisible! They're just covered by deck plating and carpeting ;).

[MMODoubter]

That is NOT artificial gravity. Artificial gravity is having some sort of plate on the floor that draws matter towards it. WAY more complicated.

[vpr]

What about metallic, magnetic suits and magnetic floor.

[ThomasPlaysTheGames]

You should do a video on Project Orion, which would have been a nuclear ( bomb ) powered spacecraft, which could have vastly shortened times for interstellar travel .

[noontide]

spin them while they sleep... that way the astronauts are lying down and not becoming as disoriented when they move. i believe the vessel at 3:02 would be useful to test it out.

Nautilus-X was an amazing concept, a shame there is never enough political will for science/space things, wish someone just strip away a good piece of the military share and transfer it to science/space.
