Cosmologists have spent decades striving to understand why our universe is so stunningly vanilla. Not only is it smooth and flat as far as we can see, but it’s also expanding at an ever-so-slowly ...

For all its tumult — erupting stars, colliding galaxies, collapsing black holes — the cosmos is a surprisingly orderly place. Theoretical calculations have long shown that the entropy of the universe ...

The second law of thermodynamics is one of those puzzling laws of nature that simply emerges from the fundamental rules. It says that entropy, a measure of disorder in the Universe, must always ...

Theoretical physicists and cosmologists deal with the biggest questions , like “Why are we here?” “When did the universe begin?” and “How?” Another questions that bugs them, and likely has bugged you, ...

Cars run out of petrol, stars run out of fuel and galaxies collapse into black holes. As they do, the universe and everything in it is gradually running down. But how run down is it? Researchers from ...

A new study proposes a radically simple and efficient way of calculating the complex physical quantity known as entropy -- and it probably exists on your own computer. Entropy, a measure of the ...

Imagine you’re standing in front of a closed door. Behind it is a teenager’s bedroom, and your task is to rate how messy it is on a scale of 1 to 10. But here’s the twist: you can’t open the door – ...

Looking back a variety of distances corresponds to a variety of times since the Big Bang. Entropy has always increased from any moment to the next, but that doesn't mean that the Big Bang began with ...

Entropy, a measure of the molecular disorder or randomness of a system, is critical to understanding a system’s physical composition. In complex physical systems, the interaction of internal elements ...
