Question

What is the hottest object in the universe?

Answer 1

The hottest thing that we know of (and have seen) is actually a lot closer than you might think. It's right here on Earthat the Large Hadron Collider (LHC). When they smash gold particles together, for a split second, the temperature reaches 7.2 trillion degrees Fahrenheit. That's hotter than a supernova explosion

Answer 2

By zapping a piece of aluminum with the world's most powerful x-ray laser, physicists have heated matter to 3.6 million degrees Fahrenheit (2 million degrees Celsius)—making it briefly the hottest thing on Earth.
