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.

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 General Relativity Rabbit Hole: Unraveling Space, Time and the Fourth Dimension Parsing Albert Einstein's theory of our universe -- an idea that's utterly mind-bending, yet seemingly shatterproof.

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.
