lol Nigel. My pal Al said the first part but the second part is better.

It a poor article Helen. Space-time exists.

Picture this; if you were to RACE away from the face of a noontime clock at the speed of light, when you look at the image of the clock racing along with you it will be frozen at noon no matter how long you travel.
For both you and the image of that clock moving at the speed of light TIME HAS STOPPED. Time will vary, going slower the faster you go until you reach the ultimate speed limit where time stops.

If you can picture that, just know that you can't go the speed of light because you have mass.
Massless things can only go the speed of light.

Time sort of emerges from velocity and distance in space.


Gravity is nearly as easy to picture as an emergent force, But its a longer story.
