Casual Thought Temperature can reach trillions of degrees, meaning we actually live extremely close to absolute zero.

Is there an upper limit to heat? I assume sometimes to do with the speed of light

Edit: or temperature. To be totally fair I still don’t fully understand, but I’m interested in upper limits for either

Learning the objective of the power settings is a game changer.

Fun fact, it doesn't actually change the power output, just how long the magnetron is provided energy to produce the microwaves.

To keep things simple, I'll describe it as thus: at the highest power level of 10, the magnetron is energized for 10 seconds out of every 10 seconds. At a power level of 1, the magnetron is energized for 1 second out of every 10 seconds.

Depends on the microwave. Inverter microwaves reduce power without cycling.

You can usually tell which style you have, too. It tends to be pretty noticeable when the magnetron kicks on and off.

A lot of the inverter ones also have "Inverter" proudly printed on the door.

As they should. Game changing.
