I said in theory, it might not be possible given our current level of technology.
The Earth is spinning or rotating at the velocity of 1,674.4 km/h (or 465.1 m/s).
You can't suddenly stop the Earth rotating, and then restart it again at this same velocity.
If you study physics at all, You would know that it is not scientifically possible. It is delusional wishful thinking that people still believe that such thing can happened.
I am saying that the Earth can stop rotating, but it will have to gradually slow down before it came to a full stop. A sudden or an instant stop is not possible at all.
And the Earth cannot instantly resume rotating at 1,674.4 km/h. It would have to gradually accelerate to reach this speed, and that may the Earth thousands of years to reach this rotational speed.
The reason being is "momentum" and "inertia".
Sure we can spin a coin on a table, and then stop the coin instantly with our hand, because a coin is a small object that doesn't have much mass.
But the earth is a really large object that you can't stop or start its rotations instantly, because of momentum and inertia. It will require a super massive force to stop it instantly, and even more massive force to move from zero km/h to 1,674.4 km/h, but only if you want to throw physics out the window. It is wishful fantasy, if you think that scientifically possible.
The more massive object, the more forces it will require to move an object. And the more massive object is, the more forces are require to slow it down.
A driver can stop his large massive truck with breaks, but because of it mass, it has to decelerate first to slow down the truck before it become stationary. The truck would have travelled some metres between applying break and actual stop, because of momentum.
And it would require a lot of mechanical forces for the truck to start moving again, and it would continue to accelerate before reaching the speed it was originally, before applying the break.
It would be similar with the Earth's rotational velocity. It cannot possibly go from 1,674.4 km/h to zero km/h, instantly; nor can it go from zero km/h to 1,674.4 km/h, instantly. The earth is simply too massive for that to happen.
The whole idea that the sun will stop for a whole day, before resuming its course, is nothing more than make-believe fantasy. Joshua 10 is such make-believe, and people who believe that such thing can happened, are uneducated in science.
Miracles, as portrayed in the bible, is nothing more than - at best imaginative (would make a good story, if you can suspend reality while reading books) - at worse, superstition (if you literally believe that such thing being possible).
And superstition is nothing more than a belief triggered by one's ignorance and fear. But how is superstition any different from paranoid delusions?
