求各位英语高手翻译下面一段话(汉译英)

科学家们认为:宇宙中各种物质的运动都有特定的规律,通过认真的分析及借助可延伸人们感觉的仪器,人们可以认知这些规律.
scientists believe that every body in the universe has a specific motion, and through careful analysis and instruments that expand humans' senses, these specific motions can be found.

宇宙是一个大的体系,其中物质运动的规律有很多相同之处.尤其中一部分获得的知识可应用到其它领域.
the universe is a huge system, in which the motions of various bodies will have many similarities. hence these knowledge can be applied to other systems.

例如万有引力定律,可以解释物体落向地球的运动规律,同样可以解释星体运动规律.
for instance, gravity, which explains the free fall of bodies on earth, can also be applied to the movement of the celestial bodies.
