Scientists Predict Star Collision Visible To The Naked Eye In 2022 (npr.org)

Scientists predict that a pair of stars in the constellation Cygnus will collide in 2022, give or take a year, creating an explosion in the night sky so bright that it will be visible to the naked eye. From a report on NPR: If it happens, it would be the first time such an event was predicted by scientists. Calvin College professor Larry Molnar and his team said in a statement that two stars are orbiting each other now and "share a common atmosphere, like two peanuts sharing a single shell." They predict those two stars, jointly called KIC 9832227, will eventually "merge and explode ... at which time the star will increase its brightness ten thousand fold becoming one of the brighter stars in the heavens for a time." That extra-bright star is called a red nova. They recently presented their research at a meeting of the American Astronomical Society in Grapevine, Texas.

    aren't they really predicting that the light from the stars colliding will reach us in 2022?

      Yes, but since they can't please normal people and pedants, they've gone with the description that both can easily understand.

    It takes zero time for the light from the event to reach us in its frame of reference. According to the photons the event is zero distance away. So I'm not sure it makes any sense to talk about when or where the event happened.

    Goddamn scientists, always predictin' shit and figurin' stuff out.

    Selfish bastards, at this rate there won't be any new discoveries left for the next generation of scientists to make.

    I interviewed several of the photons tomorrow and they called bullshit on your concept of zero distance.

    You're begging for a "your mom is so fat" joke here, hope you're aware of that!

    Or is that ``a "your mom is so fat here" joke''?

    If we send somebody to Mars and are listening to their final screams of agony as they realize there was a conversion error between Metric and Imperial, are they dying right now or have they been dead for 13 minutes?

    It's a bit late to do something about it in either case, is it not?

  9. What Einstein figured out... by number6x · · Score: 4, Interesting

    What Einstein already figured out is that as you approach the speed of light, in your reference, time slows down. If you reach the speed of light, time stands still.

    What Einstein already figured out is what the post you replied to is alluding to. For a photon, all time is now. To the photons reaching us from this event, it is exactly the same time as when they were created. To a photon, no time passes between when it is emitted and when it is absorbed. This is one of the most spectacular implications of relativity.

    It will temporarily be about as bright as Polaris, the Pole Star. So visible to the naked eye, but not one of the brightest ( https://en.wikipedia.org/wiki/... )
