What Happens At The Edge Of The Universe? | Space Time | PBS Digital Studios
The universe doesn’t have a single, physical “edge” that can be reached like a cliff—what people call an edge is usually a boundary set by causality....
Did Time Start at the Big Bang?
The Big Bang didn’t “start time” in the literal, clock-like way many people learn in school; in the standard Einstein general-relativity picture, the...
How Cosmic Inflation Flattened the Universe
Cosmic inflation is the leading explanation for why the observable universe looks both causally connected and nearly perfectly flat—despite those...
Why Magnetic Monopoles SHOULD Exist
Magnetic monopoles—isolated north or south magnetic charges—remain unobserved, but the case for them is unusually strong because multiple layers of...
What If The Universe DID NOT Start With The Big Bang?
The strongest takeaway is that modern cosmology still points toward a past boundary—often interpreted as a beginning of time—because geodesics in an...
What Caused the Big Bang?
Cosmic inflation is built around one central mechanism: a quantum field can get trapped in a “false vacuum” with constant, positive energy density,...
What If The Speed of Light is NOT CONSTANT?
The speed of light is treated as a universal constant because it underwrites the causal structure of the universe: it sets the maximum speed for...
Black Holes from the Dawn of Time
Black holes may have formed in the universe’s first moments—and if they did, some could still exist today as “primordial black holes” (PBHs). The key...
Physicists Rethink Time… And It Solves Several Big Problems
Physicists are proposing a way to tame the “end of time” problem inside Einstein’s general relativity by importing a symmetry that quantum physics...
Can Space Time Remember?
Gravitational waves may leave permanent “memory” in spacetime—tiny, lasting changes in how distances and motions line up after the wave has passed....
