All of time and space

-

There is something very strange about space. It propagates light at 186,000 miles per second. At that speed, light takes four years to get to the nearest star. The speed of light is always measured the same no matter the speed of your spaceship or your planet. Nothing can go faster than the speed of light except space itself. A voyage to the nearest star at light speed would take four years to get there, and four years to get back, but onboard clocks would show only about two months had lapsed.

Does radar work at near light speed? Yes. Electromag­netic waves leave your ship at light speed and return at light speed relative to your ship. So your ship could maneuver to avoid asteroids. Space is not just space; it is also time. That’s why it is called space-time.

Space-time is omnipresen­t throughout the universe. It is everywhere matter is not. It is between the galaxies, the stars, and the atoms. The spirit of God is also omnipresen­t. Without space-time, there is no gravity and consequent­ly, nothing at all.

For those who are not religiousl­y inclined, they should know that there is a vast difference between the God of the Old Testament and the God of Jesus. We know nothing of Jesus between the age of 12 and when he began to preach. Some would say that he was influenced by Hinduism. I have studied his teachings over and over all my life. I have come to the conclusion that all you need is love, and all the rest becomes clear. We are all his children. Our spirits emerge from God’s spirit when we are born. He is our mother, and he loves us the way a mother loves her child. That is why he (Jesus) did what he did so that we can be forgiven—and forgive and love one another.
