Absolute zero is the coldest temperature we can imagine. At this temperature, everything would stop moving.
It’s marked as 0 Kelvin (K). That’s the same as -273.15 degrees Celsius (°C) or -459.67 degrees Fahrenheit (°F).
Even though this idea is important in science, getting to absolute zero is nearly impossible. This is due to problems with technology and how energy works.
Scientists have ways to get close to absolute zero. They use special techniques such as laser cooling and cryogenics.
Here are some of the challenges they face:
