Scientists of Harvard speculate that the first interstellar visitor is an old aien spaceship

Resultat d'imatges de Scientists of "Harvard" speculate that the first interstellar visitor is an old alien spacecraft


SUMMARY

In October of 2017 the astronomers of the University of Hawaii detected an object named "Oummuamua", which means explorer in Hawaiian.

 At fisrt they thought it was a comet, an idea that was discarded as it lacked a tail and a comma. Later it was believed that it was an asteroid, but it wasn't known why its acceleration. And they even thought it could be an alien spaceship.

After several studies it has been concluded that it could be a "light sail", that is a spacecraft that is propelled by radiation pressure and that has been sent by another civilization to look for signs of life, and now it's in disuse.

GLOSSARY. Tail and comma: two parts of a comet.


COMMENTARY

 Actually, everyone would like that the third idea was the right one, becouse discovering that is another civilization in the universe, would be the greatest discovery for humanity. Now, the chances of this object being artificial and coming from another part of the galaxy are very small, since it could be an object that had never been seen from Earth, but it already existed.

So, I think, although all the other possibilities have been discarded, we shouldn't assume that it is the remaining idea, and continue investigating about other causes that could have influenced this strange case.

But, it's also true that everytime, we have the feeling of being closer to a great discovery as the scientific and tecnological advances are being amazing. In summary, if everybody continue investing in this, we will discover a lot of things, and maybe some that are unthinkable nowadays.

Criptozoología Alex Lapuerta

Criptozoología La criptozoología significa literalmente: 'el estudio de los animales ocultos' y es una pseudociencia que se ocupa de la búsqueda de animales cuya existencia no ha sido probada. Los animales de interés criptozoológico son llamados «críptidos», término creado por John Wall en 1983. Esto incluye a especímenes vivos de especies extintas, como algunos dinosaurios, animales que carecen de evidencia pero aparecen en mitos y leyendas, como Piegrande, el Chupacabras o el Monstruo del lago Ness; y animales salvajes lejos de sus zonas geográficas, como gatos fantasma. La criptozoología no es una rama reconocida de la zooligía ni de ninguna otra disciplina científica. Es un ejemplo de pseudociencia debido a que confía fuertemente en pruebas anecdóticas, relatos y supuestos avistamientos.

Hallan animales bajo un kilómetro de hielo en la Antártida - Resumen El equipo de científicos que ha perforado un kilómetro de hielo sobre el lago Mercer, a 600 kilómetros del polo sur, en la Antártida. Los investigadores hicieron este descubrimiento cuando examinaron algunos sedimentos situados bajo el lago. Allí encontraron restos de algas que vivieron hace millones de años cuando la Antártida era mucho más cálida y de animales mucho más recientes. Entre ellos hallaron carcasas de tardígrados u osos de agua, un pequeño crustáceo similar a una gamba y zarcillos quizás procedentes de una planta o de un hongo. - Fuente https://www.abc.es/ciencia/abci-hallan-animales-bajo-kilometro-hielo-antartida-201901182148_ noticia.html#ns_ campaign=mod-outbrain&ns_mchannel=abc.es&ns_source=organico&ns_linkname= desktop-tablet&ns_fee=AR23_1fila - Fecha de publicación                                                                                   19

THE BONOBAS HELP THEIR CHILDREN TO FLIRT SUMMARY Most mothers of mammals take care of their children until they reach adulthood, when they become detached from them or become independent. But with the bonobas the concern goes further; they take care that their children mate, even stopping the attemps of other males. Bonobo moms are capable of everything for make their children parents. When their childs try to mate and another males prevent it, mothers chase away these males. After several years of observing four groups of bonobos that inhabit the "Congolese jungles, the authors of the study found that where the mother is present, adult children are up to 3,14 times more likely to be parents than other males. However, the bonobas do not do the same with their daughters. Despite several years of investigation, the scientists didn't detect behaviours that facilitate their mating.
