  • How did Earth get here?

    Seriously. We have no idea where it came from. Just *poof*- it appeared. People are running around looking up to the sky... We got nothing.

  • Is it "racist" or a scientific fact that some races are superior to others?

    Best answer: “Superior” and “inferior” is an uncouth way to put it, but yes there are documented biological and psychological differences between the human populations, whether you want to call them “races” or something else. They explain why there’s those differences you’ve outlined as well as the differences in... show more
    Best answer: “Superior” and “inferior” is an uncouth way to put it, but yes there are documented biological and psychological differences between the human populations, whether you want to call them “races” or something else. They explain why there’s those differences you’ve outlined as well as the differences in susceptibility to certain medical problems (e.g. skin cancer, sickle cell anaemia, etc) and why athletic abilities are not evenly distributed among the races.

    The idea that the races are physically and cognitively equal is a laughable delusion driven by ideology, not science. There is no evidence that equality exists. The reason why very few scientists and social scientists discuss this is because it’s taboo and would result in career suicide, we’ve seen what has happened to those who go against the liberal orthodoxy- those like Nicholas Wade, James Watson (Nobel laureate in medicine and physiology), Bruce Lahn, Richard Lynn, William Shockley (Nobel laureate in physics), etc.

  • Evolutionarily, why are human-beings the ONLY evil species among ALL animals?

    ONLY humans are the animals who're VERY evil, and can do EXTREMELY HORRIBLE stuff to each other as well as other animals, for NO reason (all other animals only hurt each other if there's a valid reason). Humans are the worst among all living things. Every other animal species is LESS WICKED than us. Why... show more

  • Is the idea of being "more evolved" a misunderstanding of evolution itself?

    I often hear this from people. However, the use of the word "more" in reference to evolution implies a subjective assumption. The assumption that evolution has a direction. Doesn't evolution simply state that all organisms are in a gradual state of transformation? Stating that something or someone... show more

  • Aliens: Megawatt Lasers. Why can't someone explain to these fools they will never get a reply. Energy decays with distance logarithmically?

    Best answer: Ok - energy/unit area falls off like one over the distance squared from the source of the energy. With a laser, energy/unit area still falls off like one over the distance squared, but since the laser starts out as a collimnated, coherent beam, it does not spread spherically - the disk describing the beam profile... show more
    Best answer: Ok - energy/unit area falls off like one over the distance squared from the source of the energy. With a laser, energy/unit area still falls off like one over the distance squared, but since the laser starts out as a collimnated, coherent beam, it does not spread spherically - the disk describing the beam profile increases as spreading the energy over a greater area.

    There probably isn't a lot pf photons/m^2 in available when you go 10^15 m or more away from a laser (1 yl ~ 10^15 m) so it is questionable if an alien civilization many ly away would be able to read a message out of the background noise due to ambient light from their won sun, stars, atmospheric gases, artificial lights, etc.

I’m confused with it all and was wondering if someone could explain or if anyone else has experienced the Mandela effect themselves, I’m really interested in this stuff so I would appreciate answers;)

    Best answer: Earth has a Magnetic Field
    Just like any Magnet its Flux travels in a wide loop towards the Poles
    If you can imagine Iron Filings clinging to the poles of a Magnet
    The Earth's flux does the same
    But with the Solar winds
    The get funnelled down towards the poles and collide with Molecules in the Atmosphere, exiting them, and making lovely waves of colours
    The Aurora Borealis is the Northern Lights and in Antarctica, it is called the Aurora Australis
