Key Takeaways on What Space-Time Is Einstein's theory of general relativity views time similarly to width, height, and length. As such, both time and space can be curved by gravity.

Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy.

A novel theory of 'wavy space-time' suggests that the division between our best descriptions of the universe on its smallest and largest scales may be because gravity does not play by quantum rules.

Textbooks give strange, imprecise explanations of where things happen in quantum mechanics. Consistency with gravity needs a fresh approach.

Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy.

Key Takeaways: Einstein’s general theory of relativity shows that gravity is the result of a mass, such as a planet or star, warping the geometry of the merger of time and space known as space-time.

A new study may help answer one of the universe's biggest mysteries: Why is there more matter than antimatter? That answer, in turn, could explain why everything from atoms to black holes exists.

We've been through the first few episodes of our crash course on general relativity, and came out alive! But it's officially "time" for CURVED spacetime. Join Gabe on this week’s episode of PBS ...

It's easy enough to state the bare essence of the theory in a couple pithy statements: "Matter and energy tell space-time how to bend, and the bending of space-time tells matter how to move." ...

The theory also argues that time comes in three dimensions rather than just the single one we experience as continual forward progression. Space emerges as a secondary manifestation.
