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.

    • @Sanja Glavasevic you are correct. But what is this? An object to make space travel easier because *We don't have good space abilities YET* This is in-efficiant if we had good space abilitties. Good cheap rockets. and so on. This is a bad idea if we had good travel capabilities. We have no need for this if we have good rockets. BUT untill then this will do. Besides it will take a long time to craft into mars.

    keytron1keytron1Dzień temu
  • why we dont do this?

    RalzoneRalzoneDzień temu
    • Because it is costly and we don't take enough ships from space to send. If we want this to work, we must have 1 ship coming to Earth for 1 ship leaving the Earth or as the video says this structure will fall into the Earth. Also did i said it would be costly? Yeah it will be costly

  • I love the videos! In this one, however, you are incorrect. The technology for creating a tether cable does not exist. Carbon Nano Tubes are not long enough to make a tether. This is the same issue with a Space Elevator. I'm not saying it won't ever happen, but there are a LOT of issues why the tether and space elevator ideas struggle. I hope it does happen someday!! The technology to do what you're suggesting is about 1000 years away ... given the way technology evolves. Maybe 2000. Considering the bow and arrow took many, many thousands of years to become redundant as a weapon of war. For example, rocket technology has not really changed for 100 years. By that I mean, it's still a combustion process. The rocket has adapted to the use of small and powerful computers and 'some' relatively minor improvements in materials science. For example, SpaceX still uses Stainless Steel which has been around more than 100 years. Materials Science is the main blocker here. Materials need to be developed that are far better than what we have now. The tether cable not only needs to hold the massive weight perfectly for let's say 5 years, which would be about 50,000 cycles. The tether cable needs to also withstand the huge flexion and resistance to stretching (it will be like a spring) and micro-meteorite damage and tiny fractures and cracks etc etc etc. It's very, very complex and does not exist. It would need to be resilient like the heat shields on the space shuttle yet flexible like a rope and stretchy like a rubber band. THEN, there's the excessively complicated control issue of managing the rotating mass ... so many issues I'm not EVEN gonna type them out. It's not as bad as saying invent a time machine, but it's an extremely complicated problem that you have oversimplified incredibly. Keep up the great work! Love your videos! Very thought provoking!
