    It gets weird, though, when we consider that the speed of light does vary depending on the medium in which it travels

    And that we don't really know the speed of light.
    We can measure the 2 way speed of light in a experiment (there and back) but what if the speed going there is 2C and back is instantaneous ?
    Huh ? 🤔😵‍💫
    Veritasium on Youtube presents such stuff I think to just confuse me at a higher level.
    It's working. 🤯

    Watching a Falcon Heavy take off should be on everyones Space bucket list. First time in 3 years SpaceX will try for the 10/27 launch and best of all its a 8pm launch \. A night time Falcon Heavy is a sight to see for sure


    Falcon Heavy is the most powerful operational rocket in the world by a factor of two. With the ability to lift into orbit nearly 64 metric tons (141,000 lb) Falcon Heavy can lift more than twice the payload of the next closest operational vehicle, the Delta IV Heavy. Falcon Heavy is composed of three Falcon 9 nine-engine cores whose 27 Merlin engines together generate more than 5 million pounds of thrust at liftoff, equal to approximately eighteen 747 aircraft.

    Farking monster it is

    In case something goes wrong? I think I'll be watching that from a distance......like, a completely different state kinda distance.....

    Back to Blue Jets for a moment....

    hw1hzoc5nyla.png

    Blue jets zip upward from thunderclouds into the stratosphere, reaching altitudes up to about 50 kilometers in less than a second. Whereas ordinary lightning excites a medley of gases in the lower atmosphere to glow white, blue jets excite mostly stratospheric nitrogen to create their signature blue hue.

    Now, back to your regularly scheduled programming....

    Well that was depressing...

    And this only shows you the initial and immediately following impact damage. The post-impact damage after all of the ejected debris have a chance to spread out in the atmosphere, we get reduction in sunlight making it to the ground, temp drops, plant life extinctions, flash vaporization of water in some of the large impacts...

    Good times will be had by all!

    I think it's safe to say that last scenario in the video is pretty much one and done. :#

    So with the last impact that'll be the equivalent of 1040 BILLION Tsar bombs, are they saying that there's no chance of survival ?
    Gosh, that's rather pessimistic ! 🤔☢️🤯


    BTW the Tsar Bomb was pretty interesting; blew a hole in the sky. 👍

    In the case of the last scenario, we would no longer even have an atmosphere to worry about. Definitely a mass extinction level event. The planet would look a lot like Mercury.

    Forgive me if this is a re-post, but to me it's amazing the number of private companies wanting to get into the low earth orbit game lately. SpinLaunch is using a novel way to get the payload into the upper atmosphere, without the burden of lifting huge amounts of fuel along the journey! Spin it, and fling it up high, and then use down-scaled rocket engines and fuel to it's destination!

    Just a reminder that there will be Sonic booms going off on Tuesday, November 1st, about 7 minutes after lift-off for
    Spacex Falcon Heavy. Launch is currently scheduled at 9:40AM EDT. This rocket will be lifting off in Cape Canaveral, FL.

    The sonic booms are caused by the boosters coming in for a dual landing....each booster will create its own sonic boom, if clear you can watch the reentry...and all this happens after the lift off of a Falcon Heavy the most powerful rocket in the world.....

    ^ Flacon Heavy can hold the title for a little longer.
    SLS may get launched early Nov.?

    The highlight of this launch will be the dual sonic booms as the boosters come back home.....SLS looking at Nov 14th night time launch which will be another must see

    Over 200 million Americans watched the total #solar eclipse in August 2017, but no one had a better view than photographer Jon Carmichael. He spent years plotting how he could capture the total eclipse in a unique way, eventually combining his passions for photography, astronomy, and flight.

    This sonic boom was heard in many States...East of us you could see the fireball....was very cool....and this coming week we try for a moon shot again

    TOP SECRET X-37B SPACEPLANE ENDS RECORD 908 DAY MISSION
    The U.S. Space Force announced the landing a X-37B space plane after a record 908 days orbiting Earth--four months longer than any of the previous five X-37B flights.
    The robotic X-37B touched down at NASA's Kennedy Space Center (KSC) in Florida today (Nov. 12) at 5:22 a.m. EST (1022 GMT). … See more

    ARTEMIS IS GO FOR LAUNCH
    NASA just concluded a Pre-Launch Mission Briefing with media where officials stated that other than a few minor issues, the SLS Rocket & Orion spacecraft are ready for launch at 1:04am Wednesday, Nov. 16

    Mission Managers stated that a small piece of insulation peeled away from Orion during Hurricane Nicole, is about 10 feet in length, and it is a "very very thin layer" about 0.2 inches thick.

    NASA says "We do not have access to repair this at the pad". NASA says it is not concerned about "liberated debris" hitting critical components during launch.

    According to NASA, this RTV insulation material is there to essentially fill in a small gap in the Orion spacecraft where there otherwise would be some aero heating, not an insulation concern.

    Mission managers will meet again Monday morning to get full approval to launch Orion

    WOW this was without a doubt a most fantastic launch...the entire sky was lit up looked like the sun rising....noise wasnt as intense but the brightness from the engines was eye opening......and the sound of thousands of people clapping and yelling just made it that much better....this is a must watch for any space nerd....lots to do and see in the area
