WOTD: Grainy

Did you know you can still hear and see the reminents of the Big Bang.

First you have to get your hands on an analog TV. When you turn it on you will be met with grainy static and garbled noise. 

The image you see is a visual representation of the radiation caused by the Big Bang, and the noise is an audible one.

You can also test this out on an fm radio by running it to any non used frequency. You will hear “white noise” which is the same thing.

Now you know.

Sleeping ants.

Did you know that ants┬ádon’t really sleep.

Reasearch has shown that ants tend to follow a pattern of taking 8 minute naps roughly every 12 hours. They do this as an entire group.

Other research shows that some ants sleep up to 5 hours a day in short 1 minute power naps. While an ant queen can sleep 8 plus hours a day.

Now you know.
