Is the universe running out of stars?

Here’s a good question posed by the folks at Advanced Science News. And they not only pick up on it, but they answer it, because if we ask a question, we can do it too. So are we running out of au ba stars? Do we need to go through more problems or stay with the ones we already have?

Well, it seems the universe really is running out of stars. The fact is that in some regions of the universe, new stars appear nine times less than 10 billion years ago, the most fruitful period from this point of view. For more than ten years, researchers have been analyzing the brightness of galaxies that we have been able to observe so far.

And this is starting from the ones closest to the Milky Way and ending with those located at a distance of 13 billion light years. They then grouped the galaxies by distance. Thus, by means of a comparative analysis, it was possible to estimate the luminosity fluctuations that occurred over time. And it was concluded that new stars are formed not as often as at the beginning.

The reasons are complex, there are many, obviously we don’t know them all, but one of the most important would be that supernovae scatter the gases needed to form new stars. This may seem surprising when we consider that our Sun also appeared as a result of a supernova that set the dust and gases of the primordial nebula in motion.

But, say the aforementioned researchers, if supernovae are too powerful, they scatter the gases, sometimes even beyond the galaxy, so bye-bye, new stars.

What will happen in the future? Well, at this rate, the universe will be dominated by black holes, dead stars, and it will turn into a vast cold dark space. Now don’t rush to get your fat clothes! This will happen in at least a thousand billion years. Come on, sir, we’re scared! This is where they should have started. Finally, if you want to be prepared, you can start stocking up now, but we say don’t panic too much.

What happened to the Patagonian slopes because the world invaded?

Several publications have given multiple headlines on the back in the last few hours. Namely, that a new rule of evolution, a new paradigm, had just been discovered, starting with some observations made on a species of sleds in Patagonia.

In principle, the matter is simple. In the south of the Andes mountains, among other species of animals, one of the moose is also found. The Parsis live on both sides of the mountains. It is interesting that the specimens on the western slope are more massive than those on the eastern slope, and no one knew why, they are simply of the same breed. In fact, it is only by DNA that you can tell that they are the same species, otherwise they are not very similar.

Without holding your breath, let’s say that there is a hypothesis that could explain these differences in size within the same species. One of the earliest said that animals that live at high altitudes tend to become larger in order to better retain heat. In fact, this is the same scheme as a piece of meat, which after heating cools longer if it is larger. But this is not the point here. In the end, it seems that it will be all about precipitation.

That is, since there is more precipitation on the western slope, there is implicitly more food. More feed for fallows, since they are also not on a diet, leads to an increase in size. As it is, what has been known since the beginning of time has just been discovered. And the conclusion: stop following the headlines that announce such revolutions, because 99% are not real!

When did the flowers actually appear?

Well, here is a good, useful news that you can quote when giving a bouquet of flowers to your wife, girlfriend, secretary, boss, colleague, etc. If you mention the origin of flowers and how their evolutionary paradigm is changing because of this new research, you will make a big impression and have nothing but sentimental gain. Please, nothing will impress women and men more than a little lesson in paleobotany!

In general, you should know that all discoveries so far have shown that flowering plants appeared in the Cretaceous period, about 130 million years ago. Well, some recent discoveries claim that they appeared right back in the Jurassic period, about 180 million years ago. In any case, they appeared during the time of dinosaurs.

Well, DNA analysis of 100-million-year-old amber-encrusted plants from the Ramnaceae family found in Myanmar suggests that the plant family may have originated at least 260 million years ago. This practically doubles the age of flowering plants compared to all previously known ones. Not only do they no longer appear in the Mesozoic, that is, the period in which the dinosaurs also appear, but they move into the Paleozoic, a time period in which there should not have been a race.

We don’t need to point this out to you, but such information would come with rewriting the entire evolutionary story. As I said, tell your loved one this when you give them a bouquet of flowers! See how impressed she will be!

First impressions really do matter!

The fact that first impressions are important has become a scientifically proven fact. And, say researchers from the University of Warwick, Great Britain, to reach this conclusion, they analyzed 168 subjects. Then the subjects were allowed to chat with an unknown person for a few minutes. Another 170 people did not communicate with anyone. They were then asked to play themed games with strangers.

It turned out that all the subjects of group I had already formed an opinion about the personalities of the interlocutors, and their game strategies were based on these ideas. The rest just wandered around, not having a very clear idea of ​​what to do, because they didn’t know anything about their opponents.

The authors of the study say that this shows us how important social conversation is in planning future actions. Even if you don’t manage to discuss some ideas about saving the planet together, a little exchange of ideas is very useful in relationships and actions with those around you. Didn’t we tell you that too? Just forget about the news above. Start a discussion about paleobotany, Darwinism, and evolution with a random person. You will remember us.
