Non-rocket spacelaunch is the idea of reaching outer space mainly without the use of rockets, which today is the only method in use. Transportation to orbit is often the limiting factor in space endeavours. Present-day launch costs are very high ” $3,000 to $25,000 per kilogram from Earth to Low Earth Orbit (LEO). To settle space, e.g. space exploration and space colonization, much cheaper launch methods are required, as well as a way to avoid serious damage to the atmosphere from the thousands, perhaps millions, of launches required.

ABSTRACT
Antimatter is exactly what you might think it is -- the opposite of normal matter, of which the majority of our universe is made. Until just recently, the presence of antimatter in our universe was considered to be only theoretical. In 1928, British physicist Paul A.M. Dirac revised Einstein's famous equation E=mc2. Dirac said that Einstein didn't consider that the m in the equation -- mass -- could have negative properties as well as positive. Dirac's equation (E = + or - mc2) allowed for t ....etc

A water rocket is a type of model rocket using water as its reaction mass , The water is forced out by a pressurized gas, typically compressed air. Water rocket engines are most commonly used to drive model rockets, but have also been used in model boats, cars, and rocket-assisted glide,The term aquajet has been used in parts of Europe in place of the more common water rocket
