Yes, and we far exceed it. In the laboratory, physicists reproduce nuclear fusion, that is, the union of two atomic nuclei to form a larger one, which occurs inside stars. To achieve this, they have to generate temperatures of hundreds of millions of degrees Celsius, figures that exceed those in the center of the Sun, which are only a few million degrees.

For physicists, the challenge is to confine the fusion plasma to those temperatures, something that is achieved with two systems: the use of powerful magnets – magnetic confinement – and laser bombardment – inertial confinement. The stars have solved this by using gravity, that is, by storing huge amounts of matter within them, the weight of which keeps the hot plasma compressed.
