Hi M,
In gravitational relativity, your acceleration is always an acceleration to escape gravity
You only need to accelerate to around 27,500 Mph to escape earths gravity, there is no need to accelerate past that.
So while doing this, the object where you are moving away from is accelerating too.
How is this true? The earth spins no faster, or orbits any faster because you left.
So the twin on earth begins to spin while you are accelerating outside Earth’s gravity.
No, his spin is the same as when you were on the launch pad. Earth is an inertial frame, while you accelerate you are in a non-inertial frame and when you stop accelerating at say 27,500 Mph you become an inertial frame also. You seem a bit confused about this?
Lets agree on this before we move on??
