    It always amazes me how easy physics seems with prof. Leonard Susskind as he simplifies things

    &quot;I always use Z for the vertical axis, I don&apos;t know Y&quot;. And nobody laughed.

    I can&apos;t even with this guy! I love him. He&apos;s my nap buddy. I&apos;m no physicist, so all this goes straight over my head and provides the nicest ASMR I&apos;ve ever found. I&apos;m sure it&apos;s an exciting class if you know what any of it means. Holographic universe sounds cool, but really the best I can do it let this enter my subconscious and work its way around that part of my brain just for the funsies. Kudos to those of you who get more out of these lectures! Smart people make the world go round.

    He mentioned that in one version of the reality the horizon is emitting high energy photons. So is that are what is referred to as the &quot;firewall&quot;?

    At <a href="https://www.youtube.com/watch?v=_3Z8RxXmoWU&amp;t=2160">36:00</a> says something that caught my attention ! a black hole reflect radiation that has lower wavelengths than radius of the blackhole.
