Why the increasing temperature would cause extinctions?


Pleistocene-Holocene extinction


Normally we have talked about five extinctions. But now the number of extinctions is six because at the end of the last ice-age was the extinction of the giant animals(1). If we want to prepare the threat, we must know and realize threats. And we must not underestimate the threat. The thing is that we should find a solution to the worst problem, and that is climate chancing. Some researchers have said that climate warming has destroyed species in the case of all extinctions or at least the worst of them(2). The sixth mass extinction of our planet (3). In that extinction, many mammals like Mammoths were destroyed for some reason. 


The tale is about the Holocene-period extinction, but the same model can maybe be caused also the destruction of dinosaurs. Maybe Mammoths were mammals, but they would need internal fat as well as the dinosaurs, and if the temperature would rise for a long time, the behavior of animals would change. And then they would not collect internal fat for winter, and then suddenly something drops the temperature. 


At the end of the final ice-age, the reason for extinction was the fast rise and drop of the temperature. When the long warming period stopped suddenly and the temperature started to move fast up and down that thing caused a more dangerous situation than some warming or freezing alone. 


The similar effect can kill dinosaurs


There is a possibility that climate warming, what had continued a long time would increase the effect of the nuclear winter after the volcanic eruption, which might be connected with the asteroid impact. When the asteroid has impacted the Earth, that thing happened at the worst possible place. 


One of those bites dropped on the Yucatan peninsula, but some other bites would be impacted the water. That kind of thing can cause the worst tsunami ever, and if that asteroid has been crushed to smaller bites that can explain the large area of the effect of the impact. 


Some of those bites might be the cosmic snowballs, what have exploded on air, and some of them would cause the impact wave, which travels in the magma layer. That thing caused volcanic eruptions all around the world. 


How meteorite what impact on the ground can cause a volcanic eruption at the other side of the planet?


When the meteorite impacted the ground, that caused the fast decrease of temperature. And if dinosaurs were not prepared by collecting fat in their bodies, that kind of thing can be devastating


The cosmic snowball would explain the reason, why that meteorite was not left the impact crater on the Earth. Or by the way, The Gulf of Mexico might be the result of the meteorite impact but is that the meteorite, what caused the extinction of the dinosaurs. When cosmic snowball hits the lithosphere, the impact energy would be transmitted to the magma and continues to travel to the other side of the Earth. And then the magma would be pressed out from the volcanoes. 


But if the climate has been warm a long time the dinosaurs and vegetables would be adapted to the warm weather. Then the steam along with ash, what rise out from volcanoes and burning forests and grasses caused the nuclear winter, where the temperature suddenly dropped, and the dinosaurs froze to death. The effect of nuclear winter was so devastating because the dinosaurs were not collect fat to their bodies, and that caused death. Of course, the tsunami and fire that were caused by that meteorite were devastating.

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...

Thoughts about strong leadership

Thoughts about strong leadership Everybody knows, how the dictators would rise in the power of the nation, and the thing what makes people supporting those persons is that they offer strong leadership as the way to make nation proud. And also they have always the same parroting, the foreigners and other nations have a too strong influence in the country. But what makes those persons like some Robert Mugabe or Kim Jong Un to think that they are only possible leaders, and why people would need them? Why there is nobody else allowed to try to come to the head of the state, or even try to challenge those leaders? If they are so popular as they want people to think or believe, why they don't tolerate any kind of opposition if they are done so good and big actions for their people, that they are celebrated in every home in their country. The thing that would return the morale and spine for the nation is the strong leader, who would put the state back in order and row. The thing is ...

Next-generation nanotechnology can be independent-operating molecule-sized robots.

 Next-generation nanotechnology can be independent-operating molecule-sized robots. "A DNAzyme (red) uses its binding arms to dock at a specific location on an RNA strand (yellow) and then cleaves it at its core. High-resolution, real-time NMR, Electron Paramagnetic Resonance, and Fluorescence Spectroscopy." "As well as Molecular Dynamics Simulations are used to identify the structure. And catalytic mechanisms of the DNAzyme. Credit: HHU/Manuel Etzkorn" (https://scitechdaily.com/dnazymes-how-active-dna-biocatalysts-that-destroy-unwanted-rna-molecules-work/) The active DNA catalysts are the gate to DNA-controlled, independently-operating, molecular-size nanomachines.  The DNAzymes or active DNA biocatalysts are next-generation tools for destroying unwanted RNA. The DNA molecule is one of the tools. That can use for controlling molecular-size machines. DNA is like a chemical computer program. And if the researchers can make synthetic DNA that can make exactly what the...
