How far do your thermometer go?

How hot 
Can it get?
How cold 
Do it go?

In theory,
Numbers go for
Infinity.

Thermometer bowl
Only tells a little bit.

100 degrees water boils
The center of the sun is 
15 million degrees
  But 15 milion is nothing

Google is 100 decimal points
But what if you had a million zeros ..
That’s enough to scorch the sun 
And what about a million zeros below zero.

How hot does it get ?
and how cold can it go?
