1. Gravitational waves are real.
More than 100 years after Einstein first predicted them, researchers
finally detected the elusive ripples in space time this year. We’ve now
seen three gravitational wave events in total.
2. Sloths almost die every time they poop, and it looks agonising.
3. It’s possible to live for more than a year without a heart in your body.
8. Earth has a second mini-moon orbiting it, known as a ‘quasi-satellite’. It’s called 2016 HO3.
9.There might be a ninth planet in our Solar System (no, Pluto doesn’t count).
10. The first written record demonstrating the laws of friction has been hiding inside Leonardo da Vinci’s “irrelevant scribbles” for the past 500 years.
12. Crows have big ears, and they’re kinda terrifying.
13. The largest known prime number is 274,207,281– 1, which is a ridiculous 22 million digits in length. It’s 5 million digits longer than the second largest prime.
16. Artificial intelligence can beat humans at Go.
17. Tardigrades are so indestructible because they have an in-built toolkit
to protect their DNA from damage. These tiny creatures can survive
being frozen for decades, can bounce back from total desiccation, and
can even handle the harsh radiation of space.
22. There’s a giant, 1.5-billion-cubic-metre (54-billion-cubic-foot) field of precious helium gas in Tanzania.
23. The ‘impossible’ EM Drive is the propulsion system that just won’t quit. NASA says it really does seem to produce thrust - but they still have no idea how. We’ll save that mystery for 2017.
