The phenomenon that makes our favourite drinks bubbly is, alarmingly, the same one that causes decompression sickness in divers. Why do we still love it?
Don't start investing in flux capacitors just yet, though.
- The second law of thermodynamics states that order always moves to disorder, which we experience as an arrow of time.
- Scientists used a quantum computer to show that time travel is theoretically possible by reverting a simulated particle from an entropic to a more orderly state.
- While Einstein's general theory of relativity permits time travel, the means to achieve it remain improbable in nature.
Few could match the famous physicist in his ability to communicate difficult-to-understand concepts in a simple and warm fashion.
- Richard Feynman was a renowned physicist who conducted legendary work on quantum physics, the Manhattan Project, and investigating the Challenger explosion.
- Later in life, however, he became best known for his education work, gaining the nickname "the Great Explainer."
- His series, Fun to Imagine, works as an excellent primer to Feynman's unique educational style. Here are 9 science lessons he covers in his series.
The answer is surprisingly simple, if cataclysmic.
- A unique, tiny grain of stardust has provided a look at the early universe.
- Computer simulations point to a single neutron-star collision as a significant source of heavy metals.
- Gold is more than bling — it's in our neurons.
What if all planets were the same distance from Earth as the Moon?
- A video imagines what it would look like if the planets were all the same distance from Earth as the Moon.
- The largest planets like Jupiter and Saturn would loom large in the sky.
- Mercury is the smallest planet in the solar system.
