Kuiper Belt indicates the presence of Planet Nine
  • The science communities since a long time have been debating upon the existence of Planet Nine.
  • Space highlights different shreds of evidence based on which scientists are stating the claim.

What Is Planet Nine?

Planet Nine is a hypothetical planet present in the far outer Solar System, whose mass is estimated to be 10 times more than the mass of Earth. The planet is said to be 20 times farther than the sun than Neptune is.

What Do Researchers Have To Say?

Dr Konstantin Batygin, a planetary astrophysicist at the California Institute of Technology, said that there were five different lines of observational evidence which pointed to the existence of Planet Nine. He stated that if this theory does not sound believable, then people would have to come up with the answers of the five pieces of evidence which could lead to further confusion.

Batygin in 2016 published a study examining the six known objects in the Kuiper Belt, a circumstellar disc in the Solar System beyond the planets that extends from the orbit of Neptune towards interstellar space.

The study examines all the objects have elliptical orbits pointing in the same direction and are tilted the same way. These serve as evidence to the planet’s existence.

It is being said that the objects are tilted 30 degrees downward compared to the plane where the eight official planets circle the sun. Researchers also made use of computer simulations of the solar system including the Planet Nine and to demonstrate that there should be more objects tilted a whopping 90 degrees to solar plane. It was revealed that five such objects, which fit these parameters were already known.

The study led to the birth of two more ideas. Researchers said that this planet could have tilted the planets of the solar system during the last 4.5 billion years.

Planet Nine’s existence could also tell the reason as to why Kuiper Belt objects orbit in the opposite direction as compared to other things in the solar system.

Feminism itself is nothing but a simple movement that pursues equal rights for women (including transwomen) and against misogyny both external and internal.

"In India, to be born as a man is a crime, to question a woman is an atrocious crime, and this all because of those women who keep suppressing men in the name of feminism."

Feminism, a worldwide movement that started to establish, define and defend equal rights for women in all sections- economically, politically, and socially. India, being a patriarchal society gives a gender advantage to the men in the society thus, Indian feminists sought to fight against the culture-specific issue for women in India. Feminism itself is nothing but a simple movement that pursues equal rights for women (including transwomen) and against misogyny both external and internal. It states nowhere that women should get more wages than men, that women deserve more respect than men, that's pseudo-feminism.

Yakshi statue by Kanayi Kunjiraman at Malampuzha garden, Kerala

Kerala is a land of many good things. It has an abundance of nature, culture, art, and food. It is also a place of legend and myth, and is known for its popular folklore, the legend of Yakshi. This is not a popular tale outside the state, but it is common knowledge for travellers, especially those who fare through forests at night.

The legend of the yakshi is believed to be India's equivalent of the Romanian Dracula, except of course, the Yakshi is a female. Many Malayalis believe that the Yakshi wears a white saree and had long hair. She has a particular fragrance, which is believed to be the fragrance of the Indian devil-tree flowers. She seduces travellers with her beauty, and kills them brutally.

Ancient India not only made mentions of homosexuality but accepted it as well.


The LGBTQ+ acronym stands for Lesbian, Gay, Bisexual, Transgender, Queer, and others. In India LGBTQ+ community also include a specific social group, part religious cult, and part caste: the Hijras. They are culturally defined either as "neither men nor women" or as men who become women by adopting women's dress and behavior. Section 377 of the India Penal code that criminalized all sexual acts "against the order of nature" i.e. engaging in oral sex or anal sex along with other homosexual activities were against the law, ripping homosexual people off of their basic human rights. Thus, the Indian Supreme Court ruled a portion of Section 377 unconstitutional on 6th September 2018.
