13 crazy scientific facts that sound like fake news but are actually true
“Your head ages faster than your feet.”
We often rely on scientific evidence to help us separate facts from fiction but sometimes science can just blow your mind.
People on Reddit are sharing scientific knowledge that appears to defy logic or common sense but are actually true – and here are a few of the best.
1. If you uncoil each strand of DNA in each cell of a human body and line them from end to end, it’d be long enough to stretch from the Sun to Pluto and back. – Kisaoda
3. You replace every cell in your body every seven years. Thus, you are not the same person you were seven years ago. – Back2Bach
4. That 99.9999999% of your body is empty space. – Chinstrap_1
6. The old adage “fake it till you make it” actually has behavioural science behind it. If you don’t feel confident, but act confident, eventually you will become confident – even if you didn’t believe it about yourself in the beginning. – slinky999
7. What burns longer: A rag or a rag soaked in gasoline? Most people pick the normal rag, because gasoline is a super flammable thing that bursts into flames and will burn things quickly. Nope! The rag with gas will burn longer. Because it has more fuel. – nagol93
9. Your head ages faster than your feet. – liamemsa
10. When you glance at a ticking clock the second hand seems to hang for a moment, because your brain anticipates what you’re going to see faster than you actually see it. – BananaButton5
12. If you pick 23 random people, there is a 50-50 chance, two of them share a birthday. Seems kind of crazy considering the 365 days of the year. – Berserker-Hamster.
13. The Moon looks larger at the horizon and smaller directly above. However, it is the same size, optically. – timojenbin
