A supernova.
The Big Bang
Scientist believe that the universe by a giant explosion called the big bang .
The blast of air after an explosion is called a shockwave. It is a sudden and powerful pressure wave that radiates outwards from the explosion, causing damage to surrounding objects and structures.
big bang: This is the big bang theory
Atomic bombs, as they were called in the 40s, are nuclear weapons which use the properties of radioactive material to create an extremely powerful explosion. The explosion involves a huge release of energy and very damaging radiation. Look up "atom bombs" and you are likely to find a range of explanations.
The big bang theory which is a theory of cosmology holding that the expansion of the universe began with a gigantic explosion between 12 and 20 billion years ago
Sugar dust particles will ignite and this will be called the primary explosion, the primary explosion will unsettle more dust and cause a secondary explosion and the second blast will be more powerful. This then can be at threat to other easily combustibles items in the vicinity.
The theory that states the universe began in a violent explosion is the Big Bang theory. It proposes that the universe started as a singularity and has been expanding ever since, leading to the formation of galaxies, stars, and planets. This explosion occurred approximately 13.8 billion years ago.
A nuclear bomb creates a big explosion through a process called nuclear fission, where the nuclei of atoms are split apart, releasing a huge amount of energy in the form of heat, light, and shock waves. This release of energy happens very quickly, causing a powerful and destructive explosion.
The big bang theory does not state that "the universe began with a gigantic explosion." The theory suggests that our universe originated from an infinitesimally small point called a singularity. Since all of space was all localized within this point, the rapid expansion of the universe isn't an explosion. An explosion occurs within space, but the expansion of space itself isn't an explosion. Quite simply, there isn't anything outside of space for the universe to explode into. Thus the "big bang" wasn't big, nor did it go bang. Around the time of the big bang (about 13.7 billion years ago), the universe was much hotter and expanding very rapidly (somewhat analogous to an explosion but by no means an actual explosion).
actually it all started at a explosion called the big bang first the universe was stuck inside the explosion untill the universe began to expand inside this explosion pushing and making this explosion expand, finally when the explosion exploded the universe was formed
The explosion of a dwarf star is called a nova or a supernova, depending on the type of dwarf star and the circumstances of the explosion. Novas are less powerful explosions caused by a white dwarf siphoning material from a companion star, while supernovas are much more energetic explosions that can occur in white dwarfs or other types of stars.
