I pointed out that every object you move in space must also move in time, and vice versa. This shows they are inextricably linked. They are one thing. You have not refuted this claim. If it is wrong there should be a way to demonstrate it is wrong.

Go ahead. Prove me wrong.

"...solid matter as slowed down light."

Everything in the universe is moving at the speed of light at all times. All matter, all light, everything. Here's how it works: The faster something moves through space, the slower it moves through time, and vice versa.

Again, refute this if it's wrong.

It's not, and you can't.
