This stellar explosion will be seen on Earth in 2022, can we survive?

A supernova is truly the largest explosion man has ever seen. Each explosion is the extremely bright and super powerful explosion of a star.

Massive stars actually burn huge amounts of nuclear fuel in their cores, or centers. This produces tons of powerful energy, so the center gets very hot. The heat generates pressure, and the pressure created by a star’s nuclear combustion also prevents that star from collapsing.

A star is in equilibrium between 2 opposing forces. The gravity of the star tries to squeeze the star into the smallest and narrowest sphere possible. But the nuclear fuel that burns in the star’s core creates a strong outward pressure. This outward thrust resists the inward compression of gravity.

These fantastic spectacular space events can be so bright that they eclipse their entire galaxies for a few days or even months. They can be seen throughout the universe.

If you are seeing a star explode in the sky, it may have actually exploded more than 13,000 years ago. Light travels at the speed of light.

The speed of light = 299 792 458 m / s

The so-called “speed of light” in vacuum, commonly referred to as c, is a universal physical constant that is important in many areas of physics. Its exact value is defined as 299792458 meters per second (about 300000 km / s or 186000 mi / s). It is correct because, by international agreement, one meter is defined as the length of the path traveled by light in a vacuum in a time interval of 1⁄299792458 of a second. According to special relativity, c is the upper limit for the speed at which matter, energy or any signal carrying information can travel in space.
