  • Anti-Gravity Cone?!

    Anti-Gravity Cone?!

    Einstein thought it impossible: a ball rolling uphill! This new experiment shows, for the first time ever, a ball can actually defy gravity.

    The next video released will explain how the Anti-Gravity Cone actually works; what force overpowers the force of gravity?

  • The Coriolis Effect

    The Coriolis Effect

    The Coriolis effect says that anytime you’re rotating—whether it’s on a playground toy or your home planet—objects moving in straight lines will appear to curve. This bizarre phenomenon affects many things, from the paths of missiles to the formation of hurricanes.

    You may have heard that the Coriolis effect makes water in the bathtub spiral down the drain in a certain way, or that it determines the way that a toilet flushes. That’s actually wrong.

    Although, as you may have noticed while tracking a hurricane on the news, storms in the Northern Hemisphere spin counterclockwise, while those in the Southern Hemisphere spin clockwise. Why do storms spin in different directions depending on their location? And why do they spin in the first place? The answer is the Coriolis effect.

    More details:
    #1. Speed of sound: Unlike light, sound needs a medium to travel through, and its speed depends on characteristics of that medium like density and temperature. In the extreme environment of a neutron star’s core, sound can travel extremely fast. But knowing that sound can’t surpass the speed of light, physicists can narrow down their models of neutron stars to include only those where “extremely fast” is less than light speed.

    Scientists may have found clues to the nature of dark matter in a signal from the universe’s first stars.

    Here is the research paper: https://www.nature.com/articles/nature25792
    Authors: Judd D. Bowman, Alan E. E. Rogers, Raul A. Monsalve, Thomas J. Mozdzen & Nivedita Mahesh

    This evidence seems to suggest that the dark matter is particles that are less than four times the mass of a proton and are moving at non-relativistic speeds. This is consistent with dark matter particles being so-called WIMPs: https://en.wikipedia.org/wiki/Weakly_interacting_massive_particles.

    How to See Quantum with the Naked Eye

    Check out https://www.youtube.com/user/EugeneKhutoryansky, who was kind enough to share his water wave animation with us.

    ADVANCED SCIENTIFIC NOTE: Quantum mechanics would be much more obvious if we had very sensitive eyes. If your eyes identified each photon individually, you would see them land as described in the video, and only build up to this wave pattern. The pattern that we see can be explained classically by waves, it is *ultimately* a quantum phenomenon. The only reason it’s hard to tell is because our light detectors (eyes) aren’t quite sensitive enough.
