Leave the flies alone. You don't care about flies. Imagine you're in outer space in a spacesuit. There's no fuel in the engines. How do you move in space? There shouldn't be any jet propulsion. Is it possible to move without interaction? Without loss of mass? Solve this problem - create a grail by analogy.
and the engines on the spacesuit? or the whole ship next to it?
Even fewer people imagine how a body can move without moving anywhere .....
To overcome gravity and not react to gravitational forces, using an autonomous source of (very powerful) energy and move in one's own coordinate system, then if one stands in one's own coordinate system, one will move in another's coordinate system
SZZ: "Everything is relative" ))
Imagine that you are driving a car at 2nd space speed ....
that's about 1 km per hour :)
By the way, yes, we're all moving faster than the second cosmic speed right now. )
ZS: The Earth moves around the Sun in an elliptical orbit of about 150 million km at an average speed of 29.765 km/sec.
Engines not working ....
it's clear, a man in a spacesuit alone in space or a ship with inoperative engines nearby?
The solution to any complex problem is to break it down and simplify it, and you're making it harder ....
Let's take the option that one.
where did it come from, without a ship? )
ZS: There were flies, now astronaut, elephant soon?
Even fewer people imagine how a body can move without moving anywhere .....
Well, it's not complicated. There is a monitor in front of me on the table - standing still. However, the planet rotates and it rotates with it. Therefore, we can say that my monitor is moving while it is at a complete rest.
It all depends on which hill the observer is looking down.
