If it's possible to exit earths atmosphere from the sky going up would it also be to exit sideways and down?

    If you go in a straight line toward the horizon, you will go into space and either orbit the Earth or escape Earth.

    If you go down, you will very quickly hit the ground.

    You can go sideways, but if you follow the curve of the Earth you won't exit the atmosphere.

    And going down would be towards the ground, you can't exit the atmosphere from the ground.

    This makes no sense. Everywhere is "up" for leaving the atmosphere.

    down tends to lead to collision with liquid or solid (water or rock) so is not very useful, but you can leave in any direction you choose if you have the power that you will need.  You just have to gain enough velocity to offset the lateral (earthward) acceleration part of the problem.  Light does it all the time, after all.

    Yes, if you go fast enough you could insert into an orbit going laterally to gravity.

    You could leave altogether with more fuel and speed.

    Going down, there is a planet in the way.

    Not down, obviously, but sideways is possible in a line which is less curved than the surface of the planet. A powerful cannon built into the side of a high mountain could fire a projectile sideways in such a way that it would not fall fast enough to follow the surface and such an object would leave the atmosphere. It wouldn't be very efficient though.

      No cannons near that powerful. USNs rail gun may come close.

    Yes, but in space what defines up down and sideways depends on which coordinate system you decide to use anx what the origin point of that coordinate system is. The origin point and the directions are arbitrary, a human ade concept. Ther re basically is one two directions, up, away from the "surface" of a celestial body, anx "down". There is a sideways, but since many celestial bodies are not approximately spherical unless they have enough mass and size, the concept of " sideways" is arbitrary. The universe and space don't care. There is a failure to communicate. To a certain extent, how we perceive the Universe is subjective. "Truth" is subjective. There is no "right" or "wrong." Those are determined by human beings , societies and cultures.

    You can buy political maps of the world with south at the top. There is always some kind of distortion in any projection, and a loss of detail or resolution no matter what the scale of the map may be. The center of YOUR subjective

    Source(s): Is YOU. Your perspective is unique. So is YOUR "reality." What is up for You may be sideways for me and vice versa..

    You can exit Earth's atmosphere from any direction except the bottom because the rocket will fall down due to gravity and get lost in space
