Essay on topic "If time travel were real "
Answers
Answer:
First of all, to give you a better concept of time I will use a personal theory of mine. When you look up at the sky at night, at the stars, what are you seeing? Do you think that collage of stars actually exists? Most of them do not. When you look at the sky at night you are seeing the past because it takes an obscene amount of time for the light from those stars to reach earth, and in that time those stars may have disappeared. It works both ways. When an inhabitant, if there is one, on a planet around the star that you are looking at looks at our sun he is also seeing the past. So here we are, at the main idea of my speech - the possibility of different times and time travel. The main question here is: How do…show more content…
This has been misinterpreted many times. Einstein said that no solid object can accelerate to the speed of light. He did not state that you could not harness the power of an object or energy already going the speed of light, or faster. Another restriction is that the faster you accelerate, your mass increases and therefore to meet the speed of light you would need an infinite amount of energy because your mass would be infinite. We'll ignore that for now. . Dr. Steven Preston of London says that assuming we can propel to the speed of light, we would have to do it at a rate that the human body can withstand. We will use 1g, that being 1 gravitational force, or the same as you simply standing on the ground. If we use Einstein's theory then we could accelerate to 1g in 354 days and just short of the speed of light. Using the star Andromeda as an example, which is 2.2 million light years away (a light year being the distance light travels in a year), at that 354th day we would reverse engines and slow down to halt at Andromeda. The entire trip would take less than 2 years, but unfortunately earth would have aged 2.2 million years. This is because, as I stated before, the faster you go time slows down. We have now established how to travel into the future So how would you get back to your own time? Or how would you travel into the past?
