Question

How does Space-time push and pull on all objects? I do understand how it pulls, but I don't understand how space-time pushes on all objects?

a) Space-time expansion
b) Gravitational waves
c) Dark energy
d) Time dilation

Answer 1

Space-time pushes and pulls on all objects through space-time expansion, gravitational waves, dark energy, and time dilation.

Step-by-step explanation:

Space-time pushes and pulls on all objects through various phenomena:

1. Space-time expansion: In a universe with dark energy, the rate of expansion increases over time. As space stretches, the acceleration plays a greater role and the expansion speeds up.
2. Gravitational waves: Changes in how matter is distributed cause disturbances in the curvature of space-time, propagating as gravitational waves.
3. Dark energy: Dark energy becomes more influential as the universe grows larger and matter begins to thin out. It acts only over large scales.
4. Time dilation: Near a very large mass, space and time are distorted, causing time to slow down.
