Why is There Absolute Zero Temperature? Why is There a Limit?

The highest temperature scientists obtained at the Large Hadron Collider is 5 trillion Kelvin.
The lowest temperature that people managed to obtain is 0.000000000038 (38 picoKelvin) or minus 273.14 degrees Celsius or minus 459.66 degrees Fahrenheit.
But is there anything else hotter or colder? What does "colder" or "hotter" mean? Why are some objects warmer than others? What is absolute zero, and why is it -459.67 Fahrenheit and -273.15 Celsius? Keep watching to learn this from the video!
Absolute zero.
