Getting to space is incredibly hard, expensive and needs a lot of resources.
A more efficient way to get there is a Skyhook (or Spacetether), an ever rotating cable with a counter weight, that catapults spaceships from earth orbit into the depths of space.

    This looks very compelling! But... I'm not convinced it is depicted properly. I *think* the cable must go in and out ... to change the speed of the spacecraft by conserving angular momentum... just as a skater does by moving her arms in and out to increase/decrease rotational speed. So... when launching, the cable must be reeled into the center of the skyhook to increase the rotational velocity, and thus linear velocity of the spacecraft when it is released, so that it can escape the Earth's orbit. And conversely, returning spacecraft must be caught with a reeled in cable... and then reeled out, thus decreasing the linear velocity of the craft so that it can return safely to Earth. N'est ce pas?

    You conveniently forget to talk about the energy needed to descent from the tether at 5:29 It's not free.

    I have never seen that concept in a movie. But I never read science fiction, so I don t know how usual its placed there. Do someone know movies oor series that use that idea?

    tethers are about as risky as being catapulted into the sky 1000km and landing in the spot you wanted. You can do the math for accuracy but do you trust the precision. Not only would you land but you would be refired and hope to land on your next destination for your "interstellar journey". For our tech the flinging would save on fuel but hopefully before we need to go through with building some system like this we find other ways to travel through our solar system

    your animation is wrong on the 4:15 timeline it would hit the tether and push it back up to speed not get caught by the tether and released.

    Fascinating but many unanswered questions. Could we build a durable cable with current materials? How complex would it be to build and to deploy in orbit? What if it spun out of control and crashed? Are there any other safety risks? What if it got hijacked by people with malicious intent, could it be used as a weapon?

    This is really interesting, and has left me wanting to know why it isn't a bigger talking point/closer to a practical solution if it's "that easy" and effective? Would've loved to see the video touch on that.

    imagine missing the tether and now drifting into the emptiness and darkness of the space. that would be pretty scary
