"This process is like a cosmic CT scan, where we can look through different slices of cosmic history and track how matter clumped together at different epochs." ...

Gravity background: Newton’s theory of gravity, gave way to Einstein’s theory of general relativity (GR), which holds that gravity is not a force in the usual sense. Instead, heavy objects ...

Additionally, the concept of background independence is gaining traction in the study of quantum gravity. This principle asserts that the laws of physics should not depend on a fixed background ...
