The explosive energy of a ton of TNT is 4.184*10° Joules, according to Google. A megaton of TNT is a million times that. According to Wikipedia, the Isar Bombae was the most powerful thermonuclear weapon ever exploded, at 50 megatons of TNT. (For comparison, the explosive energy of WWII nuclear bombs was about 20 kilotons.) Suppose one kg of antimatter came into contact with matter. How would the explosive energy compare with the explosive energy of the Tsar Bomba? (c = 3* 10° m/s) There is no way to compare the two. The Tsar Bomba produced at least a hundred times more energy than the kg of antimatter. The kg of antimatter would produce at least a hundred times more energy. They would be approximately the same.
Stellar evolution
We may see thousands of stars in the dark sky. Our universe consists of billions of stars. Stars may appear tiny to us but they are huge balls of gasses. Sun is a star of average size. Some stars are even a thousand times larger than the sun. The stars do not exist forever they have a certain lifetime. The life span of the sun is about 10 billion years. The star undergoes various changes during its lifetime, this process is called stellar evolution. The structure of the sun-like star is shown below.
Red Shift
It is an astronomical phenomenon. In this phenomenon, increase in wavelength with corresponding decrease in photon energy and frequency of radiation of light. It is the displacement of spectrum of any kind of astronomical object to the longer wavelengths (red) side.
