How Far Can We Go? Limits of Humanity (Old Version – Watch the New One)

   Hey Everybody! So this video has a mistake and we remade it!  You can watch the corrected and updated Version here: https://youtu.be/uzkD5SeuwzM

   What is the mistake? In a nutshell: It is not PHYSICALLY impossible to leave the Local Group as we said in this version. It is just extremely unlikely that we’ll ever do it, even for the standards of our videos.
   BUT: If you have a lot of time and a fast spaceship you can still fly to a limited amount of galaxies – these galaxies will eventually get out of reach forever but until then, they are within reach. Although every second some of them escape us forever.

   Ok, if this is so why did we keep the video up and not purge it when we deleted our addiction and refugee crisis videos? Well, it has to do with the nature and severity of the mistake: This mistake was much more straight forward then with the other two videos, so we did talk to a few astrophysicists to ask them what they thought and if we should take down the video. Their feedback was pretty clear, they thought it was still fine as the universe expansion things explained in the video are correct and they didn’t consider the local group thing as too major. This was actually a case of “good enough”.

   Also, back when this original upload happened, Kurzgesagt was operating at pretty tight margins and just redoing a video was not easy for us. Back then the team was small and we were fighting to put new videos out. So we just swallowed the bitter pill and kept the video around.

   But the video still bothered us, as far as we know this was the biggest unfixed mistake on the channel. Super frustrating, especially because the core idea of the video is so fascinating. The limit of our species. The actual limit. So yeah, we finally remade the video, sorry for taking this long, life got in the way.

   The original video will stay up, you can compare the two if you want to see how far we have come in a few years in terms of production quality. All in all, we could only grow the channel and work on getting better because of direct support from you guys. So thank you for that. – Philipp

   So that´s why in all those games, the "lost ancient civilizations" always seems to know more and have more adavanced technology. Because back at their time, they could see more then we do. LOL

    I don't know what you think, but maybe we should just switch off the dark energy. I mean, it's just a suggestion.

    … or can we at least dim it down a bit?

    Probably for the best. Humans destroy and devour everything. We don’t deserve even our own planet let alone access to the entire universe

    the aliens at about 6 minutes in the video are actually ferengi from star trek, mainly from star trek deep space 9. this is about in the year 2370 and humanity became a type 2,5 civilisation. ferengi are not curious, the only thing that made them a type 2,2 civilisation is pure greed…

    god made the universe Strech apart. becueas there are places in the universe that are so far apart you cant see them. god can be in charge of such great distances, god made the universe expand the bible says that god created light which is the big bang. the streching of the universe represents different barriors humans may never be able to reach after all where only human. but god can do anything. he created planet stars galaxys milky way local group and observable universe

    and still we spend our time figting among ourselves instead of trying to figure out dark energy.

    Perhaps, the when we get to milkdromeda, we get a Big Crunch into another big bang, and each cluster does the same, perhaps all of these clusters will become their own universes

    I'm on a Kurzgesagt binge so I'll watch this video to support the channel, but definitely I'm going to the new version straight afterwards to get the most correct information!
