It stands to reason that, with technology and our understanding of the world changing so rapidly over the past several decades, at least a few of the things we were taught back in the day would no longer be applicable.

Even so, you may not have considered these seven “facts,” or when, exactly, they became obsolete.

#7. Who built the pyramids?

It wasn’t the Israelites exiled to Egypt, since the massive structures were erected before the Jews existed.

#6. The names of the nine planets.

In 2006, the International Astronomical Union decided that Pluto is a dwarf planet, and therefore doesn’t count. So there are only 8.

#5. The toilets in Australia.

If you’re still under the assumption that the water spins the opposite way down the drain in Australia, you’d be wrong. The reasoning behind the claim is the coriolis effect, but it’s not strong enough on Earth to affect small appliances like a toilet or sink.

#4. The hardest material in the world is…

I bet you said a ‘diamond,’ but if so, you’d be wrong. According to the Scientific American, there are two substances that are (quite a bit) harder: wurtzite boron nitride and lonsdaleite.

#3. You can’t see the Great Wall from outer space.

According to NASA, the Great Wall is only visible from a max of 1200 miles up – low Earth orbit, not outer space.

#2. How witches were killed.

In the United States, more witches were hanged than burned, especially during the Salem trials. Witchcraft was punishable by hanging here – in Europe, where the crime was heresy, more burning was done.

#1. Your favorite dinosaur is dead…again.

There’s no such thing as a brontosaurus. Womp-womp.
