My favourite science fact is that mice sing. Male mice sing to get a girlfriend – but their song is so squeaky and high-pitched, that we can’t hear it. It’s a bit like bird song, but in the ultrasonic range!

Weird science fact – a human can survive for about 3 weeks without food, but less than a week without any water. Our bodies are 60% water and we can’t function without it!

The first dinosaurs appeared 234 million years ago, T.rex evolved 66 million years ago. That means T.rex is closer in time to Stonehenge than it is to the first of the dinosaurs!

In my job I search for neutron stars – these are zombie stars that come back to life after the initial star dies in a supernova explosion. Anyways, they are very heavy. Like very very very heavy. And a cool fact about these zombie stars is that one teaspoon of a neutron star weighs as much as 550 million T-Rexes!
At least I think that’s a cool fact – it’s a nice astronomy fact but with added dinosaurs.

Hi 676cars46,
I will go for a computer fact:
The first actual computer “bug” (a bug is an error in the code or programme that causes an incorrect and/or unexpected result) was identified in 1947 as a dead moth. It was stuck in a Harvard Mark II computer. 😀 https://en.wikipedia.org/wiki/Computer#Bugs

Nerves are the railways that our body uses to send messages around. Our bodies send different messages at different speeds depending on which nerve they’re using, what the purpose of the message is, how much information is contained in it and how healthy we are. Some messages can travel as fast as 268 mph.

That you can be cooled down to -273.15 deg C and still be 0K (zero Kelvin)
– bad thermal engineering joke – sorry

We’ve known for some time that the human eye can detect a single photon. We’ve just discovered that the same is true of the human mind.
