It is very clear that there are minor differences among 4 Fiqhs (Jurisprudences) (School of thoughts) (Shafi, Maliki, Hanbali and Hanafi). The group of these 4 Fiqhs are calledâJamaat e Sunnahâ and the followers of these Fiqhs are called Sunni.
A Heavy Spacecraft weighs between 15 and 50 tons, and requires between five and twenty crewmen. A spacecraft is incapable of interstellar travel. A spaceship is typically larger than a spacecraft, typically above 40 tons in weight. A Light Spaceship weighs between 40 and 100 tons and requires ten to thirty crewman. A Medium Spaceship weighs between 100 and 1000 tons and requires twenty to five-hundred crewmen. A Heavy Spaceship weighs more than 1000 tons and requires over five-hundred crewmen to operate. A Spaceship is incapable of interstellar travel.
Theoretically, if a spacecraft could maintain an acceleration of 1 g for the first half of a journey and the same deceleration for the second half, this would provide an equivalent to full Earth gravity for the entire trip. Even smaller accelerations are enough to negate the worst health effects of weightlessness.
