Attacking the arrow-of-time mystery along the lines Barbour and colleagues suggest may reveal that the universe is eternal.

The Arrow of Time: Still a Puzzle Explore the arrow of time dilemma and its quantum solution, revealing insights about entropy's role in the universe's evolution.

The Arrow of Time and How to Reverse It Season 6 Episode 36 | 10m 36s | CC Ever wish you could travel backward in time and do things differently? Good news: the laws of physics seem to say ...

One arrow of time to rule them all? A toy universe that, without any special help, shows time has a direction.

“When our universe ends, will a new universe start in all the new empty space?” This is a fascinating possibility, and one we must consider.

The perceived arrow of time, however, seems largely independent of anything entropy or thermodynamics may do. What, if anything, happens when we bring the expanding Universe into the equation?

The temporal direction of these baby universes will be random, making our own Universe's arrow of time a matter of chance, rather than privilege.

An anti-universe running backwards in time could explain dark matter and cosmic inflation.

In physics, they are all the same thing. But to you, me, and everyone else, time moves in one direction: from expectation, through experience, and into memory. This linearity is called the arrow ...
