    So every time there is an Earthquake it is shutdown for months? Then this information is used by Politicians to make money in Tech stocks. In return ..they get funded for millions. I guess the process works.

    I feel aliens perfected this, using solar light to power their spaceships. We are just now touching the surface of this technology with solar panels. This is how I feel aliens can travel to different galaxies and solar systems at the speed of light… It seems to be the only logical way…

    When SLAC refers to brightness, it’s important to remember that’s not beam power. Brightness is actually amount of power in a subtended solid angle. Or more colloquially how tightly is the beam focused. Last I heard from project scientists, LCLS-II was under delivering design power and over filling its focusing optics. That is to say, not very bright. But maybe these are just the normal start up transients for a big project. It’s important to sort out reality from hype.

    I only don’t understand why these people are talking and explaining things with masks on their faces. This is utterly idiotic. It spoils the whole video.

    • Andy Altman

      January 2, 2022 at 12:26 am

      Because we trust science! Thanks for watching!

      In the last experiment hall, there seemed to be a lot of “human exposure” within the large chamber. When it’s pumped down and active, how much can residual skin or other bio-detritus affect the experiments, or is it a non-issue?

    • David B

      January 3, 2022 at 11:34 pm

      Oh, and don’t you have the option of removing certain posts? If so, please get rid of the “Ernest Radner” posting and its replies, as they’re just Crypto spam. The “report” option is totally useless. so active removal is best.

    “A femtosecond is to a second, what a second is to the age of the universe.” WOW, that’s a pretty unfathomable number. This is quite the elaborate machine, how much does it cost for a single run of this beast? The power cost alone has to be several thousand dollars per run.

    i guess it isn’t bothered by earth quakes (bay area has a few) and traffic vibration. i’ve driven over that thing thousands of time, always wondered what was going on.
