Fusion Energy
Although a star's "birth" is well-defined, it doesn't correspond to an ignition event in its core. Here's how stars are actually born.
13.8 billion years have passed since the Big Bang, but many stars will survive for longer than that. What's the longest-lived a star can be?
Tech designed to fuse atoms might be able to clean up space, too.
Scientists have been chasing the dream of harnessing the reactions that power the Sun since the dawn of the atomic era. Interest, and investment, in the carbon-free energy source is heating up.
A massive nuclear fusion experiment just hit a major milestone, potentially putting us a little closer to a future of limitless clean energy.
Light can be turned into heat, which can then be turned into motion, and the effect of that motion can be turned into a big squeeze.
It could cut the time needed to reach Mars in half.
Don't put all your eggs in one basket.
Its implications go well beyond the Earth itself, affecting even the future of space travel.
If you gave me $400 and I gave you $3.15, would you consider yourself wealthier? That's a financial analogy for the supposed fusion power "breakthrough."
A next-generation LHC++ could cost $100 billion. Here's why such a machine could end up being a massive waste of money.
Just because you have “star” in your name doesn’t mean you are one. When we think about the objects in our Universe, they fall into two categories: self-luminous objects, like stars, […]
