Look around you. Where are you? Where is this place you are occupying? Somewhere in a room, maybe in a city on a continent on a planet orbiting a star in a galaxy among billions. But… where is all of that? While this may feel like a daft question, it turns out that the concept of an absolute position is something humans made up.

In a nutshell, the universe is a big bag of space that has things in it. If someone removed all these things, the stars and planets and black holes and dust, there would just be empty space left. In empty space, the concept of having a position loses all meaning. Empty space is uniform, the same everywhere.

      Absolutely Magnificent video

    • Charles Davis says:

      I’m confused. How could you staple nothing to space time, yet you said making wormhole in space time could be possible?

      Hello Kurzgesagt!

      I was thinking on an interesting topic for a video: Kinetic bombing.
      Tho I have tried to do some research, I haven’t been able to find a lot of information on the subject. Maybe you could dig a bit more deep into it!

    • SkullCrusher Gaming says:

      You make great video’s 💪

    • Georgian countryball says:

      Your animation has improved drastically well done kurzgesagt

  2. Jim Browning says:

    I am in awe of your animations. Brilliantly well done as always Kurzgesagt.

  3. Dr. Chris Raynor says:

    It is always a pleasure to see a new Kurzgesagt video in my subscription feed. Complex, high-level topics explained so simply and eloquently. So wonderful. If you ever need any orthopedic insight for a video, don’t hesitate to reach out. 👍

    They say that when you can explain a difficult concept with easy words, it means you are smart.
    Well, the people scripting this video must be geniuses then.

    You guys have conveyed one of, if not my most, favorite thing about astronomy – how *everything* is relative, and how everything is always changing, even though a lot of those changes are very slow compared to human timescales. The measuring of positions in space – astrometry – is genuinely one of the most fascinating (and frustrating, haha) subfields of astronomy

  6. Alucard says:

    I remember having conversations about how “stillness” is so relative. It’s insane to think about how if we wanted to be “still” we’d have to counter ALL of this: the Earth’s rotation, the Earth’s revolution around the sun, the sun’s movement around the galaxy, the galaxy’s movement through intergalactic space. “Still” compared to everything we can see moving would be MOVING… uh… thataway… at millions of kilometers per hour.

  7. DefendTheHouse says:

    Maybe the best visualization of this topic ever. Animation team is insane.

  8. Powerhouse of the Cell says:

    Absolutely beautiful. Your team makes animation look easy so flawlessly, your viewers should feel lucky to get such high-quality content

  9. Joe Peck says:

    I’ve had a lot of fun simulating n-body orbits in unity, the crazy patterns that emerge from switching around references frames is so cool to see.

    Kurzgesagt: Where are you?
    Me: *Disintegrates*
    Kurzgesagt: 3 motivation sentences at the end of the video
    Me: *Comes back to live*

    Great job Kurzgesagt, really, I don’t know what we would be doing without you! Amazing video!
