The new investigation shows that supernovas are not exploding without warning. That makes predicting those interesting and powerful phenomena more accurate. If there is the possibility to make the prediction when some star explodes. That thing opens new views to observe things like forming of neutron stars and black holes.
The problem with supernovas is that they explode almost without warning. But making more accurate predictions makes it possible to turn telescopes into that exploding star and observe the entire explosion.
On earth is a limited number of telescopes that can look at a certain point of the universe and find some useful data from that point.
Observing an exploding supernova that explodes 3000 light years away from us requires extremely large telescopes. For making observations that have enough accuracy.
Those powerful telescopes are always busy. And they are needed for many other observations. When those telescopes are following some star, they are away from something else.
When supernovas are seen from Earth, they have already started their eruption. And that means that the beginning of that eruption is out of data.
Certain signs give a tip that the star is going to explode. When a star loses its hydrogen fuel. It starts to burn helium. And in that process, it turns into a red giant. In those stars, helium is the main energy source. And helium fusion requires more energy than hydrogen fusion. When the fuel of the star is going to end it starts to pulsate faster and faster.
The reason for that is that the energy that comes from fusion pushes the star's core outside. That thing decreases pressure and temperature in the nucleus of the star. When energy production turns lower the star will start to collapse until the new energy pulse pushes its core away.
So when the fuel in the star will end that means the star is starting to pulsate faster and faster. Until the fusion material in the star ends. That causes the collapse of the star. During that collapse, the star's energy production increases to the level where it creates as much energy as it produced in its entire existence until it turned into a supernova.
The massive energy production means that the shockwave starts to travel outside the star. The supernova always forms neutron stars or black holes, depending on its mass. A supernova is one of the most fascinating things in the universe. There is the possibility that those eruptions form warp bubbles.
In that hypothesis, the powerful energy impact forms the situation where the supernova pushes all quantum fields from around it. Also, those extremely high-energy reactions are giving information about things like wave-particle duality. Can a high-power electromagnetic field turn the light element heavier?
Extremely large-size stars are also fascinating because they are forming also the heaviest elements of the universe. The thing that makes those stars interesting is that the supernovas can uncover when elements like uranium form. The ability to predict the supernova explosion makes it possible to turn the observation instruments to that exploding star.
Are those heaviest elements forming during the normal fusion reaction of the red supergiant? Or are those heaviest elements forming during the supernovas? That thing makes many very interesting thoughts in the minds of astronomers and physicists.
