Spoiler alert – in the future there never will be artificial gravity – astronauts won’t be able to walk around in spaceships.
In the movies most spaceships like the Starship Enterprise employ a convenient technology they call “artificial gravity” to overcome this weightlessness problem. In a few movies they even rotate parts of the ship, though the part of the ship that rotates often has no relevance to the part of the space ship people are walking around in.
No matter. Walking around is a convenient way to avoid a big budget.
Weightlessness is a pesky little problem and we’ve become comfortable accepting that on spaceships of the future you’ll be solidly on the floor. Venture outside to fix anything and you’ll be weightless maybe (unless you use something they call “gravity boots”) but inside, put something on a table and it stays on the table. People won’t be weightless in spaceships in the future.
That’s why they call this stuff science fiction. There won’t be any artificial gravity and to the dismay of Kirk and Spock a spaceship that looks like their’s will have weightless people inside.
Another design, a real design, for a spaceship that would actually have “artificial gravity” is called the Von Braun spacewheel, and envisioned in movies wanting more realism. The Von Braun spacewheel looks like this contraption. Of course, it spins and as it does the occupants inside experience centripetal acceleration, also sometimes known as artificial gravity.
So why doesn’t NASA build one of these?
Well, along comes the real world, pushing Hollywood right outta there.
They don’t have the lifting power to get all the parts up there. It’s doubtful the Falcon-heavy will be utilized for such a project.
Assembly and then pressuring it inside are formidable obstacles. This is not impossible, but beyond available budgets.
Zero gravity laboratories, like the present International Space Station have taught us that research in microgravity environments is valuable.
With exercise, astronauts do just fine, so why bother?
Alas, we may send people to Mars one day, but those poor ol’ chaps will be weightless all the way, and exercise like they do on the ISS.
That Earth sure is spinning quickly, isn’t it? Once around every 24 hours! Wow. Can you imagine being out in space and looking down, waiting to see things fly off into space from the equator?
The problem is, when you’re out there in space looking down, the planet is rotating so slowly you can’t see it move. It takes a whole day just to go around one time. You could stare and stare at it and hardly notice it turning at all at that pokey speed. Nothing’s going to fly off the equator into space at that rate.
These stupid “flat earth” people have no common sense. They give these stupid arguments just to confuse people.
I’m going to answer this and go beyond and explain a lot more.
Flat earth believers don’t fly to the underside of the earth and take pictures because, they say, there’s a dome over the whole thing, which is why we have a “wall of ice” to prevent us from getting out and walking over to touch it. It’s a convenient idea to avoid various dilemmas like the one you pose: flying over the edge to look at the other side. Here’s an image that illustrates their belief, showing the Earth, the dome, and the movement of the sun.
Please note, in this image below, the shape of Australia.
Notice, in this image, the sun is over Australia. This is a picture of what flat earth people think Australia looks like:
Let’s compare this image to actual distances. Below you can see Australia is actually 2,511 miles wide. You can drive it. There are roads.
Now in the image below you can see that Australia is almost as tall as it is wide using actual measurable distances.
So flat earth people believe Australia is much wider than tall, which is the only way they can depict Australia on their flat earth map. Below is what Australia actually looks like:
One of a billion problems with flat earth maps is they cannot account for the distortions that they see. This can only be rectified by using the spheroidal earth model.
So there you have it. The real reason they can’t fly underneath to see the flat Earth is that the Earth isn’t flat!
Is there any satellite imagery of Earth’s poles or even Earth at all? Of course there is imagery of the poles and the earth as a whole. You must know that. No, the earth is not flat.
But it matters not because no matter what I tell you or show you, you will still go on believing the world is flat and NASA is involved in a giant conspiracy. I don’t even know why you ask these questions. You don’t want to hear why your narrow minded ideas are not accepted by anyone except a small group of kooks.
