Whoaa, Thanks For Educating Me About That

whoaa, thanks for educating me about that

read about it a bit and turns out that ligers, tigons, white tigers, and liligers look pretty cool but they have many problems that are reaally uncool.

here’s something from a PETA article:

“White tigers’ neonatal mortality rate reportedly exceeds 80 percent. And they are at significant risk for facial deformities, impaired depth perception, retinal degeneration, abnormal cranial structure, cataracts, cleft palates, mental impairment, kidney problems, cardiac defects, Parkinson’s disease, scoliosis, and other spinal problems.”

“Ligers (the result of breeding a female tiger with a male lion) frequently have to be delivered by cesarean section because they’re predisposed to gigantism and often don’t survive. Like all big-cat hybrids, they frequently suffer from neurological defects, sterility, cancer, arthritis, organ failure, and diminished life expectancy.“

“Tigons (the result of breeding a female lion and a male tiger) are not expected to survive infancy and—in the event that they do—have a heightened risk of suffering from a number of neurological and physical conditions, all so that exhibitors can make money selling tickets to see them.”

which is quite sad,,

The hybrid offspring of lions and tigers

Contrary to what one might think, tigers and lions are not different species (based on the strict definition, but you should know that there are like 26 or something different definitions for species) since they can reproduce together.

The offspring of male lion and female tiger is called liger. It is bigger than tigers and lions. This is because female lions mate with many males and due to that the offspring may not have the same father. It is beneficial to the male that his offspring manipulates the female to invest in it more than in the offspring of other males. It is not good to the female and that is why she has a counteradaptation to the manipulation. Tigers’ mating system is different. Because of it female tigers don’t have such an adaption, causing the offspring of her and a male lion to become huge: the hybrid offspring manipulates the mother and she doesn’t have a way to avoid it.

The offspring of male tiger and female lion is called tigon and it is smaller than tigers and lions. This is because male tigers don’t have an adaption to make their offspring to manipulate the female, but female lions have the counteradaption to avoid being manipulated. Due to the counteradaption the hybrid offspring becomes smaller then the non-hybrid offspring.

IS THERE A PLANET NINE IN OUR SOLAR SYSTEM??

Welcome back,

Caltech researchers have found mathematical evidence suggesting there may be a “Planet X” deep in the solar system. This hypothetical Neptune-sized planet orbits our Sun in a highly elongated orbit far beyond Pluto. The object, which the researchers have nicknamed “Planet Nine,” could have a mass about 10 times that of Earth and orbit about 20 times farther from the Sun on average than Neptune. It may take between 10,000 and 20,000 Earth years to make one full orbit around the Sun.

IS THERE A PLANET NINE IN OUR SOLAR SYSTEM??

This does not mean there is a new planet in our solar system. The existence of this distant world is only theoretical at this point and no direct observation of the object nicknamed “Planet 9” have been made. The mathematical prediction of a planet could explain the unique orbits of some smaller objects in the Kuiper Belt, a distant region of icy debris that extends far beyond the orbit of Neptune. Astronomers are now searching for the predicted planet.

In January 2015, Caltech astronomers Konstantin Batygin and Mike Brown announced new research that provides evidence of a giant planet tracing an unusual, elongated orbit in the outer solar system. The prediction is based on detailed mathematical modeling and computer simulations, not direct observation.

This large object could explain the unique orbits of at least five smaller objects discovered in the distant Kuiper Belt.

“The possibility of a new planet is certainly an exciting one for me as a planetary scientist and for all of us,” said Jim Green, director of NASA’s Planetary Science Division. “This is not, however, the detection or discovery of a new planet. It’s too early to say with certainty there’s a so-called Planet X. What we’re seeing is an early prediction based on modeling from limited observations. It’s the start of a process that could lead to an exciting result.”

The Caltech scientists believe Planet X may have has a mass about 10 times that of Earth and be similar in size to Uranus or Neptune. The predicted orbit is about 20 times farther from our Sun on average than Neptune (which orbits the Sun at an average distance of 2.8 billion miles). It would take this new planet between 10,000 and 20,000 years to make just one full orbit around the Sun (where Neptune completes an orbit roughly every 165 Earth years).

Astronomers studying the Kuiper Belt have noticed some of the dwarf planets and other small, icy objects tend to follow orbits that cluster together. By analyzing these orbits, the Caltech team predicted the possibility that a large, previously undiscovered planet may be hiding far beyond Pluto.

They estimate the gravity of this potential planet might explain the unusual orbits of those Kuiper objects.

Astronomers, including Batygin and Brown, will begin using the world’s most powerful telescopes to search for the object in its predicted orbit. Any object that far away from the Sun will be very faint and hard to detect, but astronomers calculate that it should be possible to see it using existing telescopes.

“I would love to find it,” says Brown. “But I’d also be perfectly happy if someone else found it. That is why we’re publishing this paper. We hope that other people are going to get inspired and start searching.”

“Anytime we have an interesting idea like this, we always apply Carl Sagan’s rules for critical thinking, which include independent confirmation of the facts, looking for alternate explanations, and encouraging scientific debate,” said Green. “If Planet X is out there, we’ll find it together. Or we’ll determine an alternate explanation for the data that we’ve received so far.

"Now let’s go explore.”
