Temperature

In summary, the highest temperature ever recorded on Earth was 134 degrees Fahrenheit (56.7 degrees Celsius) in Death Valley, California in 1913. There is a theoretical limit to how hot it can get, known as the Planck temperature, which is approximately 1.416 x 10^32 degrees Kelvin. It is not possible for temperatures higher than the Planck temperature to exist in our known universe. The highest temperature that a human can survive in is around 120 degrees Fahrenheit (48.9 degrees Celsius) for a short period of time. Scientists use a variety of instruments and techniques to measure extreme temperatures.

I know that there is an absolute 0, but is there a highest possible temperature that an object can have?

There are several discussions already on PF about this exact thing, just asking to be searched out.

1. What is the highest temperature ever recorded?

The highest temperature ever recorded on Earth was 134 degrees Fahrenheit (56.7 degrees Celsius) in Death Valley, California on July 10, 1913.

2. Is there a limit to how hot it can get?

Scientists believe that there is a theoretical limit to how hot it can get, known as the Planck temperature, which is approximately 1.416 x 10^32 degrees Kelvin. At this temperature, the fundamental laws of physics as we know them break down.

3. Can temperatures higher than the Planck temperature exist?

No, it is not possible for temperatures higher than the Planck temperature to exist in our known universe.

4. What is the highest temperature that humans can survive in?

The highest temperature that a human can survive in is around 120 degrees Fahrenheit (48.9 degrees Celsius) for a short period of time. Beyond this, the body's internal temperature regulation system starts to fail and can lead to heat stroke or death.

5. How do scientists measure extreme temperatures?

Scientists use a variety of instruments to measure extreme temperatures, including thermometers, pyrometers, and infrared cameras. In certain cases, they may also use mathematical models and simulations to estimate temperatures in extreme conditions.
