英国科学essay代写:时间旅行

几个世纪以来,时间旅行的前景一直让人类感到困惑和好奇。时间旅行已经在我们的文化中占据了主导地位,并构成了包括H.G.威尔的《时间机器》在内的大部分科幻作品的基础。无论是想回到过去纠正错误,还是想去未来体验人类的成长,每个人都有一种想要穿越时空的欲望。然而,时间是难以捉摸的。关于它的一切,从它的存在到它的运作,都是一个谜。即使现在,我们也以每秒一秒的速度进入未来。利用光的优势,我们可以走得更快。虽然人类无法利用目前的技术限制来操纵时间,但时间旅行似乎是未来不可避免的一部分。爱因斯坦在他的狭义相对论中解释说,各个地方相对于彼此的速度是恒定的。在这一理论公布后不久,科学家们就得出结论:时间和空间并不是真正分开的。它们实际上是同一实体时空的一部分,时空也被称为第四维度。这让我们可以穿越时间。然而,要想完成一次穿越时间的巨大跳跃,光速屏障就需要被打破。以目前的技术,这几乎是不可能的。然而,新的理论和假设已经提出,似乎表明时间旅行可以发生在一个非常大的规模。通过弯曲物理定律和光本身,理论上我们可以穿越时间。事实上,许多科学家已经提出了关于乘坐超高速宇宙飞船穿越广阔的空间到弯曲时空的理论。而这些理论中的大多数很大程度上依赖于光的使用。

英国科学essay代写:时间旅行

The prospect of time travel has mystified and intrigued mankind for centuries. Time travel has been predominant in our culture and has formed the basis of a large portion of science-fiction works including H.G. Well’s “The Time Machine”. Whether they want to go back to the past to correct a mistake or journey to the future to experience the growth of mankind, everyone harbors a desire to travel in time. However, time is elusive. Everything about it is a mystery, from its existence to its workings. Even now, we are traveling into the future at a rate of one second per second. We can travel even faster by using light to our advantage. Although mankind cannot manipulate time with the current limitations in technology, time travel seems to be an almost inevitable part of the future.Einstein explains that places are moving at constant speeds relative to each other in his theory of Special Relativity. Soon after this theory was announced, scientists concluded that space and time were not really separate. They were actually part of the same entity, space-time, which is also known as the fourth dimension. And this allows us to travel through time. However, to perform a massive jump through time, the light speed barrier would need to broken. That is almost impossible with the present technology. However, new theories and hypotheses have been brought up which seem to signify that time travel could occur on a very large scale. By bending the laws of physics and light itself, we can theoretically travel in time. Indeed, theories about traveling in ultra-fast spaceships through the vast expanses of space to bending space-time have been brought up by numerous scientists. And the majority of these theories rely heavily on the use of light.
