Do you think Black Holes controls the running time? What is your assumption about time travel?

Answer 1

this is a set of answers i discussed with my friend. i have concluded that time travel will never be possible.


There is a paradox in the whole time travel situation, if indeed it will be possible to travel back in time in the future, wouldn't we know it? By now wouldn't someone have came back in time to inform the past that there will be time machines in the future? If in fact there will be time travel in the future then what would stop some one from going back to say the birth of our nation, giving our founding fathers all kinds of up to date history books and technology and making America the only country in the world, there would also be a butterfly effect in time, because every action that the founding fathers would do to change the future would cause a new version of the same history book that the time travelers brought back, until inevitably the book would say, "America wins all, end of story", or they would screw up the future so bad that there would be no time travel and the meeting would never take place. If there was time travel into the past and delicate information was obtained from the time traveler, then if the recipient of thus said delicate information acted upon this information in a way that changed the time travelers history to where time travel was not invented, then the recipient would not know of it and the meeting would have never happened. In theory, if time travel is created in the distant future, and lets say that the creator's great, great, great, great grandfather was killed in the towers on 9/11. Now if the first thing that the creator wanted to do is right this wrong and stop the twin towers from being hit, then most likely he would go back in time to eliminate the terrorist before they could attack, most likely he would kill them while they were children since children are less able to protect themselves from danger or death. Well, what if the creator did not take into consideration that upon 9/11 his great, great, great, great grandfather's son was upset about the death of his father and joined the military to avenge his father, and while in the middle east he met a woman, who unknown to him was a daughter of one of the terrorist, and he had relations with her and they brought forth a son from this that would become the creator's great, great grandfather. That means that if he went back in time to right the wrong, his great, great, great, great grandfather would not have died, his great, great, great grandfather would not have gone to war, met the woman, who does not exist now, since her father died as a kid, and brought forth his son, who is the creator's great, great grandfather, meaning that now the creator does not exist. Wow, so not only did 9/11 not happen now, but time travel will not happen either


Here is a new thought on "time travel". Some people argue that while travel to the past may never happen, but travel to the future will, now stay with me on this stratso. This is their point of view on "time", "time', which is theorized to be the fourth dimension, (the others being 1. Length, 2. Width and 3. Height.) Is viewed by them as to be a continuum, while the rest of the word knows "time" to be a plane, or a never ending flat surface into the future, the theologist that view "time" as a continuum see "time" as you would picture a rubber band, where time keeps repeating itself indefinitely. They say to travel into the future we must simply bend the rubber band until two points meet and we can jump from one point to another point via a worm whole. Although there is no evidence in science to support the theory that a worm hole, or even a black hole even exist. It is speculated that in the event of a hole that the gravity is so terribly strong that not even light can escape. In the movie Donny Darko, the worm hole was a rare phenomenon that occurred on earth, if there truly was a worm whole within our atmosphere then quite possibly the whole world could be sucked into it. If possible, nothing would survive. A different approach in travel to the future or perhaps creating this worm hole is the idea of creating a vessel that could reach the speed of light and possibly surpass it. This is the most ridiculous idea of "time travel" I have heard, think about it stratso, if you were able to out run light, which we don’t have near the technology needed for this feat because we would have to build a vessel that could propel itself to approximately 670,616,629.384 miles per hour, nothing but light goes that fast. but aside from that, if we were indeed able to out run light, then what do you would expect would happen, picture your self on a train, running on its track around the world traveling at 10 mph over the speed of light, if you were able to out run light then there would be no light in front of you, you would be able to look behind you and see the land you had just passed that is in the light, but you would be passed the light and soon the land behind you would grow fainter and fainter because you are moving further into the future without light. Newton said "time" can be related to the running of water in a river. Should the speed of the water be measured at any point, it would yield equal results. The same was thought of "time"; if "time" was measured at any point in the universe it would be the same. Suppose you and I synchronized our watches. You left on a train traveling the speed of light, and came back an hour later (according to your watch). Newton would say that I would have waited an hour for you to come back, and their watches would read the same "time". Einstein disagreed, According to his theories, "time" is relative, and it depends on the speed that one travels. Suppose that you left on the same train at 1:00 p.m. traveling at a speed of light, and suppose that I was in some way was looking at your watch. I would realize that your watch is advancing very slowly compared with mine. So if my watch said 2:00 p.m. then your watch would have said 1:05 p.m. On the other hand, you would see that I was doing everything pretty fast, as if he was in a movie that was being fast forwarded. This "time" difference applies to everything surrounding both you and I. If you returns one year later (according to your time), you would find out that I aged 12 years. Not only this, but both you and I, separately, feel normal; you does not feel that his life was moving any faster than normal, nor does I feel that his life was moving any slower than normal. While that was Einstein's theory, I speculate that the only way to travel forward in "time" is to out run "time", and if you could out run "time" then you would shoot yourself forward into a future that does not yet exist and there for you would not exist.

Answer 2

Mind you, time and space are not absolute concepts, but depend on your point of view.

For example, traveling forward in time is easy, we are all doing it right now as I write this. Traveling forward in time *relative* to the rest of the universe is possible, but it is a bit trickier. According to Einstein, if two people are moving at different speeds relative to each other, then they perceive time at different rates. Whether time speeds up for one observer, or slows for the other is a matter of opinion.

But to get to the point, If you were launch an atomic clock towards the moon, and have it circle the moon a few times and come back, it would have gained several millionths of a second on an identical clock that stayed on earth. In order for the "time dilation" to be more noticeable, you would have to travel at an ungodly speed, within about 1/10-1/5 the speed of light. This is comparable to the speed of an electron as it hits the screen of your TV set.

Again, according to Einstein, the only way to travel *backwards* in time (i.e. time dilation is negative), is to travel faster than the speed of light.

But this, and backwards time travel in general, is ridiculous for many reasons.

Not the least of which is the fact that to outside observers, your apparent mass would increase until it was *greater than infinity*......Meanwhile, to you, the mass of the rest of the universe would seem to be less than zero.....hypothetically speaking of course.... the fact that the apparent mass of objects increases to infinity as they near the speed of light is easy to demonstrate with a large particle accelerator.

Steven Hawking makes the tongue-in-cheek argument that if traveling into the past were possible, why haven't we been visited yet by people from the distant future?

Black holes are very tricky little monsters, and I don't pretend to understand them...

But, theoretically, beyond the event horizon of a black hole, time and space does not exist at all, rather like the nothing that did not exist before the big bang. It is a non-region where the laws of nature just no longer seem to apply, Thus making the statement that "black holes control the running of time," nonsensical.

Besides, what exactly is time, anyway? Is it Space? Matter? Energy? Frequency? Is it speed? All of these concepts depend on the existence of time, without providing a logical and reliable definition........How can you "Control" time if you don't even know what it is?

Ok, I am finished for now,

Answer 3

NO. Black holes have no influence on time. Time has been running (passing) since the beginning of everything. Man just decided for his convenience to divide it up into workable increments like days, weeks, months, years, seconds, minutes and hours.

Time travel is not possible with any known technology, but it does make some fantastic science fiction stories and films.
Travel backwards in time is generally thought to be impossible. Travel forward in time takes a little bit of scientific razzle dazzle that may come about some day far into the future...Who knows.

Answer 4

A proper definition of time does not exist, just a linear practical use of time, where time is measured in hours, minutes and seconds. The distance between two seconds or minutes is always the same. However according to einstein time is relative. A practical time machine that moves forward or backward is time is not feasible as per present day technology. However a breakthrough in technology may make it possible to time travel in the future. It appears that time travel to the future is possible, but backward travel is not possible, hence we do not have any time travellers from the future visit us. Even, time travellers of today (assumption) may travel to the future, but they cannot come back. It would be purely a one way travel to the future.

Answer 5

Time is relative to space. That is why the east coast is ahead of the west coast. Technically flying from California to New York is time traveling. Black holes in my opinion are not actually holes but some sort chemical. Science dictates that objects go into black holes one way and come out the other side completely broken down in atomic form. Sounds like a space age acid to me. But what do I know.

Answer 6

Gravity causes an alteration of time like speed do. But time travel is possible only to a near future, but so near that, should you travel on an airplane for all your life, you could not see the difference with your clock, even if you would be a little younger than your twin always been at home

Answer 7

I believe you need to speak with Stephen Hawking about this one. Anyways, I think that traveling forward in time is quite possible, as time slows relative to the stationary environment when you go faster.Traveling back in time however may be out of our comprehension at this point. What roles a black hole can play, I am not sure.

Answer 8

If time travel were possible,it would make no difference when it started it would be evident everywhere.
If a time machine was invented in the past it would here in the future.
If it was invented in the future it would come here to the past and if we invented one to-day it would branch out to the past and the future.
Black holes are theoretical entities that just may not exist.

Answer 9

The Vulcan science director has determined that time travel is impossible.
