distant quasar
The Universe is expanding, and the Hubble constant tells us how fast. But how can it be a constant if the expansion is accelerating?

Here's what recent DESI measurements suggest — and why it's too early to update conventional predictions about the Universe's distant future.
pulse light quantum tunnel barrier
In all the Universe, only a few particles are eternally stable. The photon, the quantum of light, has an infinite lifetime. Or does it?

With great genius comes great rigidity. Professor Barabara Oakley on how to stay mentally agile — and get smarter as a result:
space expanding
Yes, the Universe is expanding, but if you've ever wondered, "How fast is it expanding," the answer isn't in terms of a speed at all.
Food transport accounted for only 6% of emissions, but the production of dairy, meat, and eggs accounted for 83%
