What if Sun Supernova Earth

Why the sun will definitely not become a supernova

According to Wikipedia, “Supernova - when the sun explodes” is a science fiction film. I would like to protest and request that the term science be deleted. If at least the film didn't take itself so seriously ...

So actually the show was more of a disaster film. But the producer and screenwriter probably thought: Oh dear, we've already exhausted everything that nature has to offer, let's invent a completely new catastrophe. Let's let the sun explode.

But at least it's a welcome occasion to say how it is really is. Because reality is generally much better than the imagination of a second-rate screenwriter.

First of all, nothing dramatic will actually happen to our sun for the next few billion years. I can give the all-clear here. And when a popular daily newspaper with the four letters asks: Is our dear sun exploding? We can shout back with a clear conscience: No! Astronomy: 6! Put!

The sun blows out more or less strong solar wind (1), but it will definitely not explode anytime soon. Incidentally, the sun is nowhere near heavy enough to eventually perish as a supernova. At most there will be a flash of helium. Ok, that wouldn't be so nice for the earth either, but there is a difference between a China bullet and an atomic bomb explosion. Incidentally, that's how long (about 5 billion) there is. If you don't take a journey back in time as the Doctor's assistant, it can leave us pretty cold here and now.

Incidentally, this sentence then prompted me to zap away: "This is solar matter coming towards us. We don't know much about it. "

Huh ??? What do they mean what the sun is made of? And why don't we know a lot about it?

1. For at least a century we have known a lot about solar matter thanks to helioseismology and observations by space probes such as SOHO and Ulysses.

2. Above all, we know one thing: It's the same matter as it is down here. It consists of protons, electrons, hydrogen, helium and, to a small extent, heavier atoms.

It is only a little hotter than the matter normally found on earth and therefore fully charged. This means that solar matter is neither solid, nor liquid, nor gaseous, but is a plasma. This is the fourth state of matter in addition to the generally known and just mentioned three. As a result, solar matter actually behaves differently. But not because it comes from the sun and consists of a completely different material than a glass of water, for example, but because it has been heated to such an extent. On earth we can observe plasma when, for example, an object enters the earth's atmosphere. The bright glow when the space shuttle enters or the glowing up of a shooting star is usually caused by plasma. Because the air in front of the objects is compressed and strongly compressed and heated. This is the same effect that occurs inside an air pump.

3. We are all stardust. And the sun is “just” another star and a fairly common one at that. All the matter around us, the ground we stand on, the water we drink, even the building blocks we are made of ... All of this was hatched in a star at some point in the distant past. Because the original universe mainly contained: hydrogen, a little less helium and a little bit of lithium. Heavy elements were only present in traces. (2)

Only stars, through nuclear fusion, by fusing the lighter elements with one another and ejecting them again at the end of their lives, created the matter from which the earth could be formed, as well as oceans and humans. We are walking star matter.

4. Since luminous phenomena due to plasma often appear in the upper layers of the air and then go away again without us noticing anything down here, it proves that this ominous plasma cannot be that dangerous again. There is a lot of matter in the form of air in between and as soon as plasma cools down, i.e. releases its energy to the environment, it changes back to the other states of aggregation.

So I don't know what reality this film is supposed to be based on. Must be a parallel universe. And it was boring too. So at least the part that I saw before I switched.

(1) Hmm, I wanted to write something about that too. Where the new solar cycle happened to start in January.
(2) How do we know?
1. By looking at the stars. A look into space is always a look into the past. The further we see, the further we go back and recognize how stars are formed, passed and spit out dust and how the proportion of heavy elements in stars becomes smaller and smaller with decreasing age. The Hubble Space Telescope, for example, serves exactly this purpose. Incidentally, Hubble now also brings space images in Braille!

2. We catch stardust. That is what the Stardust mission did, among others. There are German researchers like Thomas Stephan, who for example also tracks down and analyzes dust particles preserved in meteorites, but who unfortunately, unfortunately, has migrated to the USA because ... Oh, let's leave that to do with retaining top researchers.

3. Particle accelerators imitate the big bang on a small scale. High-energy physicists compare their results with those of astronomers and can thus paint a very good picture of what happened immediately after the Big Bang, when the universe was so full of radiation and densely packed that light did not get very far. It is a fog that astronomers cannot penetrate with their telescopes, but particle physicists can. The more energy the particle accelerators can concentrate in the smallest of spaces, the further they look back.

But no fear. Even if the idea of ​​imitating a big bang on a small scale may sound scary.
The law of conservation of energy still applies in our universe: We can only find out what we put into it. No matter how we twist and what exotic equipment we use.

So there are really only tiny, tiny, tiny little big bangs, from which at most a few handfuls of particles come out. That's not even enough to form a small pebble out of matter. I also consider the fears that a small black hole could be created and destroy the earth to be extremely exaggerated. If a black hole were to develop, it probably wouldn't be stable for very long and would disappear under a bit of radiation.

The only thing that would change immediately afterwards would be the scientists involved. They would roll over themselves to convey this news to the world and to record the new findings in specialist articles. But I think we can live with that quite well 😉
