Can we leave earth without rocket thrust?

Question

IE: - space plane and the chap years ago who went up into near space in a baloon.

Answer 1

Outside conventional jet propulsion, and "elevators" look how far we have come in the past 100 hundred years! I think in the year 2107 we'll be looking at alternative fuels, space colonies, and the ability to travel faster then the speed of light. Maybe even fold space and Time! Its the future we are talking about hear, go back to 1938 tell Hitler the war is going to end in 1945, the US will land on the moon in 1969 and the in 2007 a person could make a phone call from anywhere in the world. The human race has come along way in 100 years.

Answer 2

You need some sort of massive thrust. Nobody has ever been able to do it without a rocket.

A "space plane" is a theoretical type of vehicle that could take off like a plane, but when it gets to a high enough altitude it switches to rocket thrust. So a space plane is really a type of rocket anyway.

Potentially you could build a huge cannon and do it that way, but the acceleration would kill anyone inside the "bullet" fired from the cannon.

Some people have talked about the idea of building a magnetic launcher usually referred to as a "catapult." Basically magnets would shoot a capsule along a track until it got going fast enough. This would probably work great on the moon, but air resistance makes it unlikely that it would work on Earth, or at least not easily.

Because your spaceship needs to work in vacuum and near-vacuum, virtually any sort of propulsion will require shooting some sort of propellant out the back. That is by definition a "rocket," regardless of what kind of fuels it uses.

So probably not, at least not with any science we know about right now.

Answer 3

The only requirement is to achieve enough energy to orbit - whether that is via rocket, or some other process - theoretically, you could build an elevator on the equator that reached 22000 miles up, the synchronous orbit distance where orbital velocity is the same as the Earth's rotational 'velocity' - by riding the elevator up, you invest sufficient energy to orbit at that altitude.
A balloon would get you pretty high (but still in the atmosphere), but would not have sufficient energy to reach orbit - just like most jet aircraft could get you pretty high, but without the horizontal vector needed to orbit - orbital velocity at the edge of the atmosphere (150 kilometers or so) is still 27200 kilometers/hour - much faster than aircraft typically fly without some boost - rockets right now are the only source of thrust that can carry an object from the edge of the atmosphere to orbit...

Answer 4

In order to leave the earth's gravitational field (i.e. go beyond orbit to the moon, other planets, etc), you need to reach escape velocity. For the earth, that's roughly 7 miles / second. That's tough to accomplish without pretty massive thrust, especially once you add on all the weight of the gear that's necessary to keep you alive.

A balloon could get you to the edge of the atmosphere, but beyond that it would not function. A balloon works because it "floats" within the denser atmosphere that surrounds it. Once you are out there in space, a balloon would not continue to rise, because it would no longer be lighter than its surroundings. A balloon in outer space is just a pretty sphere, not a mode of transportation.

Answer 5

That is the difference! Near-space is about as far as you can get without thrust. Any form of transport that needs an atmosphere to work in, baloons or planes, for example, are useless in space. SO the answer is an emphatic 'NO'!

Answer 6

No - even if it truly is fantastically a lot the way it consistently takes position, though. the first reason is that the motorized vehicle passing some days or hours in orbit provides those actually everyone a probability to verify precisely the position the motorized vehicle is and how quickly it truly is shifting, so as that the further trajectory will be computed precisely. the 2d reason is that for most deep area initiatives, there's a narrow 'window of chance' for putting off from earth. it truly is way safer to get the motorized vehicle into orbit, and then watch for the indow to open, then to go away each little thing to the basically top minute and desire that each little thing works first time.

Answer 7

no, you cannot due to the force of gravitational. If u wanna leave the Earth without a rockket thrust, u must create for u a force even stronger than gravitional force, then u could break the force and go to the space, however, u cannot survive when u get through the atmospheres, the atmospheres will create a friction on you which can burn you to dust due to your speed.

Answer 8

You could go there in a space elvator or after completion of grand unified theory or wormhole(on earth)

A space elevator is a proposed megastructure designed to transport material from a celestial body's surface into space. The term most often refers to a structure that reachs from the surface of the Earth to geosynchronous orbit (and beyond). The concept of a structure reaching to geosynchronous orbit was first conceived by Konstantin Tsiolkovsky.[1], who proposed a compression structure, or "Tsiolkovsky tower." Most recent discussions focus on tensile structures (tethers) reaching from geosynchrous orbit to the ground. Space elevators have also sometimes been referred to as beanstalks, space bridges, space lifts, space ladders, skyhooks or orbital towers.


United nature theory-wave theory. Wave theory explains every principle process that occurs in nature by introducing quant




duality= wave particle=wave formation= gravitational wave created by energetic mater as a basic force.. Energetic matter= (condensed space time, energy ) created by Einstein's space time curvature that forms nebula etc. and black hole which in its singularity (the most condensed point) expel this energetic matter in quant formation

(two semi loops)-photon, Quant equation in photon phase

1=1

Quant equation in photon phase energetic matter in both semi loops is equal. From big bang, wave creation-quant -universe, by different phase transition disperse and new universe is born. (life cycles).
This theory basically describes the formation of universe and matter but man can use it to go anywhere in this universe.


In physics, a wormhole is a hypothetical topological feature of spacetime that is essentially a 'shortcut' through space and time. A wormhole has at least two mouths which are connected to a single throat. If the wormhole is traversable, matter can 'travel' from one mouth to the other by passing through the throat. While there is no observational evidence for wormholes, spacetimes containing wormholes are known to be valid solutions in general relativity.

The name "wormhole" comes from an analogy used to explain the phenomenon. If a worm is travelling over the skin of an apple, then the worm could take a shortcut to the opposite side of the apple's skin by burrowing through its center, rather than travelling the entire distance around, just as a wormhole traveler could take a shortcut to the opposite side of the universe through a topologically nontrivial tunnel.

Only if such a tunnel existed on earth,we could walk into the doars of another galaxy or our home:depending on where the other end is.

Answer 9

Not today. We are on the bottom of a very deep well. Not only that there is a "cap" on, the atmosphere, that we always have to punch through. On the moon it is a different story. Lower gravity and no atmosphere would make it possible to get into orbit with a MagLev track.

Answer 10

There's actually been talk of a "space elevator" that would link a platform in the pacific ocean to a platform orbiting earth, but so far it's just theoretical. We don't really have a material yet that could make a strong enough supporting cable for the elevator to run up and down. However, if something like this were built, there would be no need for rocket launches to escape earth's gravity.
