In a nutshell, just try not to get yourself into a situation where ...

Since the 1960s, scientists have been experimenting with organic liquids - so-called perfluorocarbons - that can carry large quantities of oxygen. Their hypothesis: As long as our lungs receive a sufficient amount of oxygen, it doesn't matter whether the oxygen comes from air or a liquid.

Quite dramatic changes in case you have ever wondered.

To avoid a scenario we all saw in The Last of Us, we should pro-actively search for preventive measures.

Let's make Earth twice as large! It now has a diameter of roughly 25,500 km and is 8 times as heavy. It now rotates 32 times slower, meaning one day lasts more than a month. The force of gravity is twice as strong, and since weight is determined by gravity, all objects on Earth would be twice as heavy.

The good news: after every flip, the magnetic field stabilizes again. In the past, there was a magnetic pole flip about every 300,000 years, and the last flip occurred 780,000 years ago. Although we don't know exactly when it will happen, we know that

If the universe is infinite, with infinite numbers of stars, shouldn't the night sky be bright?

And why does this make us think of pizza?

By shrinking Earth, we'd finally solve the problem of long travelling distances! We'd also create a whole endless list of new problems but, uhh, let's ignore that for now. 😬

If the Sun suddenly disappears, things would go downhill quickly.

Time travel tip: Remember to always be stocked up on canned tomatoes…

Being in love impacts your body significantly! No matter which stage you're in, be it Attraction, Attachment, or Long-term commitment – a lot of chemical reactions are happening when we fall in love. And each stage plays a vital role! Let's dive into the science behind love!

Warmer temperatures cause some unexpected challenges for some animal species.

How fast do tectonic plates move? Faster than most people think! They're like giant puzzle pieces drifting across the Earth's surface, shaping our planet's landscape over millions of years.

What came first? Flowers or bees?

How much of you is already uploaded to the internet? How much of your head is in the cloud(s)? Turns out: a lot! Right now, all this information is spread out on different websites, but with new technology, we can connect it all together.

Can our universe destroy itself?

Everything in the universe strives to be in the most stable state possible. For example, a ball on top of a hill is in an unstable state. When pushed, it will roll downhill, lose its potential energy and end up in a stable, ground state.
