This is one of many attempted explanations for near Earth gravity using General Relativity. Relativists can't agree on this because none of their explanations make any sense.
"The apple falls because it's future points downwards"
Not even remotely possible, since even in relativity time is not a spacial dimension so it cannot point something "downwards" or at an object in space. That's beyond stupid stacked on top of an already stupid model of reality.
The last 6 minutes talk about a fictional "black hole".
Space and time are supposedly so "curved" within it, that nothing escapes. That's undefined nonsense because these are terms with no physical understandings attached to them.
Someone first needs to define what a "non-curved" space physically is and what a "curved" space is. What are their properties? What are the forces it exerts on an object and why? Why does a non-curved space seem to exert no forced on anything, but a "curved" space does? How does it exert a force on both light and matter? If a weight is put on a spring, how does "curved" space make the apple push down the spring?
And once again, time can't "point" to the center of a blackhole because in GR the "time" axis is orthogonal to space. It doesn't point AT individual objects within space.
Just watch the first 6 minutes of the video.

I simply ask the relativists - what is spacetime made of?
They tend to say “strings” these days.
Like guitar strings? Has anyone observed those? But I guess it sounds fancy and sciency enough for the soyence goobers.
