How can we make something hotter than the sun?

Question

It’s the sun, it’s literally a burning ball of gas providing energy to countless things millions of kilometers away… How can humans make something that is hotter than that? And how is lightning hotter than the sun?

Edit: just to clarify how is it TECHNOLOGICALLY possible? Like what do you have to do to make something hotter than the sun?

Answer 1

The trick is that those temperatures don’t last very long. A lightning strike is incredibly hot, but it’s also incredibly short-lived and the temperatures quickly dissipate to ambient levels. In comparison, the Sun will only get hotter and hotter for billions of years.
