Is it possible? If so, what would the ramp length and height need to be?

    So for physics reasons it doesn’t really matter what technique you’re using to leave Earth. If you’re going to try to go to space successfully, you’re going to have to go a minimum speed of 25,000 miles per hour. That’s called the escape velocity and it’s a different value for every body of mass in space

      Yeah but like what if the ramp went past the exosphere? Drive that rocketship up at 1mph for 100 days and you’ll be in space!

        the longer you spend at sub orbital speeds, the longer you’re spending energy to counter gravity. Building a ramp and lifting it up slowly would only be feasible if you had cheap power to do it. but over all, you’re still using most the same amount of energy to get there anyways.

        also… if you’re going to slow, you’ll just fall back down…
