| Posted By: motley crue Posted On: Mar 14, 2008 Views: 1789 | Dimensions Keith, in an argumnet (i forgot which one) someone said (i think it was Ridler) that seperating time from the other spacial dimensions is imposible and you agreed, but time can stop in a black hole. So, time can be separated and the spacial dimensions will still exist. |
| Posted By: Andres Posted On: Mar 14, 2008 Views: 1782 | RE: Dimensions Sorry but what is that that time can stop in a black hole?? Time cant be separated from the other dimensions, never, is impossible. Space and time are closely related, you cant separate one from the other. You said that the other 3 spatial dimensions will still exist, now, if they EXIST, they are moving in time(no doubt about it)otherwise they dont exist. Think about it, how can something exist without move in time? |
| Posted By: motley crue Posted On: Mar 14, 2008 Views: 1776 | RE: Dimensions Einstein said that a large gravitational field can stop time. Like one from a black hole. |
| Posted By: Andres Posted On: Mar 14, 2008 Views: 1769 | RE: Dimensions Sorry to ask, but who told you that? or where did you read it? Einstein couldn't have said that, or I dont really understand what you mean with that. Its true that a gravitational field SLOW DOWN the time of an object in it, relative to an observer outside of it, but what exactly do you mean by saying that it stops time, time as a whole, as the fourth dimension in its entirety?? How?? A large gravitational field, the one that you said it stops time, is itself existing in the space-time, the only thing is doing is distortion it. Im sorry if I misunderstood what you said. Please tell me if that is exactly what you meant, cause if it is, it doesnt make any sense. |
| Posted By: Andres Posted On: Mar 14, 2008 Views: 1768 | RE: Dimensions Sorry but i don't think you are really assimilating the fact that it's impossible to separate time from space.Think about it,before you start making any other response,and you will see why it's impossible. |
| Posted By: motley crue Posted On: Mar 15, 2008 Views: 1760 | RE: Dimensions I understand what your saying but I did watch a show about black holes and they said that time can stop in a blach hole, even Michio Kacu (dont know how to spell his name) said so and hes a theoretical physisist. The Hawking Paradox Supermasive Black hole Those are the only two documentaries that ive seen, and acording to them time can stop in a black hole, but i do understand what your saying. |
| Posted By: Andres Posted On: Mar 15, 2008 Views: 1749 | RE: Dimensions The time that youre referring to is the relative time of an object that approaches the black hole. Its time will be running slowly. It is believed that the time it will eventually stop FOR IT, once it hits the singularity. Not only the time will stop, the entire universe(remember that time cannot be separated) will be lost for it, FOR THE OBJECT THAT FELL INTO THE BLACK HOLE, NOT THE ENTIRE DIMENSION AS YOU INTERPRETED) |
| Posted By: Andres Posted On: Mar 15, 2008 Views: 1748 | RE: Dimensions I meant: The time they are referring to,not the time you are referring* |
| Posted By: Pat Posted On: Aug 10, 2008 Views: 1640 | RE: Dimensions Time does not stop at the speed of light or in the presence of a black hole, it unifies. Time as we perceive it is actually a higher dimension that we are only partially aware of. Think about it. Imagine a sphere was to interact with a 2 dimensional flatland. As it floats through the flat landers see a small circle grow to a large circle and then a small circle and then disappear. Right, now think about photographs of yourself as you start as a child, then a teenager, adult and pensioner. Time is like the interpretation of the flatlanders of the balloon interacting with their flatland. Us all getting older is our interpretation of time as it interacts with our space. Time does not stop. I hope this helps. |
| Posted By: andres Posted On: Aug 10, 2008 Views: 1633 | RE: Dimensions Your concept of time is very old actually.Your thinking of time as being absolute but in reality it doesnt flow the same for every object,and its believed that it can stop for anything that hits the singularity of a black hole. |
| Posted By: Pat Posted On: Aug 11, 2008 Views: 1630 | RE: Dimensions Time as we perceive appears to flow. The fact that we can slow time by travelling at high velocity is again a perception. All times exists, like space, at the same time. If we could somehow escape our spacetime into the higher dimension, time would then be seen as on equal terms with space and one would be able to see anytime, past or present from this vantage point. It is a misunderstanding to believe time actually flows, it does not. |
| Posted By: andres Posted On: Aug 11, 2008 Views: 1624 | RE: RE: Dimensions Its not a problem of perception,time actually slows down when we are traveling at high velocities relative to an stationary observer.Its been proved,not only theoretically but experimentally as well. If we could somehow escape our spacetime into the higher dimension, time would then be seen as on equal terms with space and one would be able to see anytime, past or present from this vantage point Thats nonsense |
| Posted By: Pat Posted On: Aug 11, 2008 Views: 1622 | RE: Dimensions Yes Andres, time slows down relative to the observer but that is to an observer within our universe. To quote the great man himself, "The distinction between the past, present and future is only a stubbornly persistent illusion" All of time is actually present all the time in our universe. You are still thinking of time in the sense that it flows, Time is a dimension that appears to slow but in reality when one travels at high velocity you transfer some of your motion from one of the dimension to the other. At all times we, and everything else in the universe is travelling at the speed of light through all 4 dimensions. When you move relative to an observer you transfer some of your motion through time into space. Higher velocity simply use more of your motion through time and turn it into space until you reach the speed of light in velocity and have no motion left to travel through time, hence time standstill at the speed of light. In reality, to the observer travelling at the speed of light he would have no motion through time and therefore not age, just as photons which have been travelling since the Big Bang. I hope this explanation goes someway in helping you perceive time correctly. As Einstein raises in the above quote, time flowing is an illusion, albeit a stubborn one. |
| Posted By: andres Posted On: Aug 11, 2008 Views: 1618 | RE: RE: Dimensions "The distinction between the past, present and future is only a stubbornly persistent illusion" When Einstein said that he was refering to the relativity of the concept of simultaneity. It is a misunderstanding to believe time actually flows, it does not. Ok when I say: time doesnt flow the same for every object what I mean is that not every object moves through time at the same rate. All of time is actually present all the time in our universe After thinking about it Ive realized that it might be true from the perspective of an observer outside our universe,as you said,but even if such a thing exists you cant take that into account when your forming a concept of time.You have to take into account the perspectives of the observers that are part of this universe,thats why is worthless to say that the slowing down of time for an object relative to other is only a perception.In fact if time dilation its only a perception then that would mean that time is actually absolute. All right I akcnowledge that I may not be understanding what youre saying.It could either be that or that youre just contradicting yourself.Ill give it more thought later with more time. |
| Posted By: Pat Posted On: Aug 11, 2008 Views: 1615 | RE: Dimensions Think of it this way. Take a pencil and a light source. Now revolve the pencil through different angles and you will notice the shadow changes in shape getting longer and shorter as you move through different angles. The pencil doesn't get any smaller or bigger but the shadow does. Time for us in our universe is like the shadow where velocity is like the changes of angles in the pencil. I appreciate this may seem somewhat abstract but it is useful to think of time in this way. We measure time from event to event when in reality we are measuring the shadow or projection of time. I strongly recommend you view this wonderful video which helped me understand the concept of higher dimension. http://www.youtube.com/watch?v=JkxieS-6WuA&feature=related |
