Gravity is not a force, it's a warping of spacetime (mostly a warping of time). It's actually a correlation of those (as explained by general relativity), but it's uncertain which causes which, or if there is another variable that causes each of those.
Here are a couple of videos that do a decent job of explaining how the warping of time makes space "flow" into a massive object.
How does gravity warp the flow of time?

I agree, time is the answer*.
But the damned thing is so complex that cs needed to name it [time complexity](https://en.wikipedia.org/wiki/Time_complexity).

That’s important for real-time applications like robotics and driverless cars. It’s the key to cypher algorithm development because determining whether cyphers are considered secure is based on the time it takes for a brute-force attack to crack them. When a cypher algorithm is “broken” it’s just because some clever mathematical way to find the key has shortened the time to an unacceptable level. Some hash algorithms are specifically designed to be time-intensive so that it makes it more difficult to conduct a dictionary attack.
When you layer the concept of general relativity on top of computational time complexity, then it’s really complex, i.e., computational time in satellites like GPS satellites that must also take into account the reduced gravitational field in orbit, which makes their clocks tick faster than clocks on Earth.

Yes, time’s scope is immense.
