I read all seven posts. That was easy since they are all identical. My opinion is that everything you say is wrong with the possible exception that your space power is equivalent to space curvature in General Relativity. But space curvature is equivalent to gravity which you dismiss; so that cannot be correct. Specifically:
1. When the stone is thrown, the force of gravity accelerates the stone downward, not in its direction of flight

2.Gravity or equivalently space curvature is what makes the moon circle the earth, as it is constantly being attracted to the earth

3.Food is constantly needed for the body to do work. When we stop working (death) food is no longer necessary

4.Source of the sun's energy is thermonuclear reactions inside the sun, not space power outside of it.

5.The sun will explode once that energy is used up. It cannot shine forever.

6.If I drop a stone on you, you will be crushed, but in this case because of the enertia the stone accumulates by being attracted to the earth

7.You theory is flawed. Please leave the subject

8.You even contradict yourself first saying that there is no doomsday and then saying that all will collapse when space power runs out.

9.You foolishness about the shadow and shrinking is just that- foolishness. Did the sun shine on the Tsunami. So why does that not happen where ever the sun shines?

Just saying something is true does not make it so.
