  • Published on: 01 March 2018
  • Is String Theory the final solution for all of physic’s questions or an overhyped dead end?

    Can you do one on Planck’s length? I’m still trying to figure out what it means. When explained, they say the time it takes light to travel over Planck’s time. Planck’s time is measured in the time it takes to light to travel over Planck’s length. Thanks either way!

    Kurzgesagt is a magic channel. Once you begin wathing a video, it begins the next one and you just can't stop watching it.

    Pretty simple really. Let's just take our most brilliant physicists and have them pontificate while on weed, then DMT, then Mushrooms, Then LSD. We'd figure out some very interesting things really quickly. It would be a real "giant leap for mankind" moment.

    Being neutral is essence of this channel, by showing only views and understanding of facts but still it was really good... 👏👏👏

    Fun fact: String theory is only viable if the universe is ten dimensional :) Edit: I just realised this is mentioned in the video, I'll show myself out. On another note, if anyone is interested in higher dimensions I'd recommend reading Flatland, by Edwin Abbot Abbot. It's an analogical novella explaining how difficult it is to understand higher dimensions.

    in this video the heisenberg uncertainty principle they said was that "by looking at a particle we change it" i was interested to know more and watched the ted-ed video and read about it online, it described it as not being able to measure both the position and velocity of something at the same time? i dont enderstand? pls help
