    To be a Genius is to be misunderstood. But to be misunderstood is not to be a Genius.

    Imagine how much more advanced society would be today if women, who comprise half the world’s brain power, were socially & intellectually enfranchised from the beginning of civilization.

    You Matter. Unless you multiply yourself by the speed of light squared. Then you Energy.

    Overnight January 4 / 5 - Earth at Perihelion - The closest distance to the Sun in our annual elliptical (oval-shaped) orbit. If you see astrophysicists dancing in the streets, this could be why.

    Not to reveal my age, but back in my day, we drew Betelgeuse bright (at Orion’s left armpit) relative to other stars in Orion.

    With stellar death comes cosmic rebirth as the spewed guts enrich nearby clouds with elements of life itself — carbon nitrogen oxygen — boosting chances that the next generation of star systems borne of these clouds will spawn planets such as Earth that cradle life such as ours.

    FYI: There is no cause to blame anything that happens to the star Betelgeuse on

    Indeed, Betelgeuse may have already exploded — now a ghost, a "dead star walking" across the Galaxy — with the light-speed signal of its demise not yet arrived here on Earth.

    Betelgeuse is the star's common name — Arabic for "Armpit of the Great One". Its catalog name is Alpha Orionis. Two thirds of all stars in the night sky with names have Arabic names. An homage to their "stellar" navigational skills 1000 years ago, during the Golden Age of Islam.

    Beginning late summer of 2019, the reddish star Betelgeuse has dropped from the 7th to the 21st brightest star in the nighttime sky. No need to panic, but If it exploded, the flash would be visible in the daytime, and rival the brightness of the Moon for weeks.

    Betelgeuse was born about 10 million years ago — long after Earth's big dinosaurs roamed the land. But the star is now near death. No need to panic, but stellar evolution models tell us that it will likely explode as a Supernova sometime within the next 100,000 years.

    The star Betelgeuse is so large, if you swapped it with the Sun, it would engulf the orbit of Mars and extend all the way through the asteroid belt. No need to panic, but at 700 light years, it's the closest star to the Sun that will end its life in a Supernova explosion.

    No need to panic, but the red supergiant star Betelgeuse (yes there is a star with that name), one of the brightest in the nighttime sky, marking the left armpit of the constellation Orion, is mysteriously dimming, having lost 60% of its brightness across the past six months.

    If I had one question for Albert Einstein, I might just mess with his head and ask, “What time does Grand Central Terminal arrive at the next train?”
