Is it possible to freeze time?
« on: October 07, 2007, 11:44:53 PM »
Well, there are some jokers from various forums say, "just put your clock into the freezer."


No, no, let's not get to that.  I heard that time slows down or stops for the object achieving speed of light, but I'm not sure.

Is it really possible?

According to Albert, the closer you get to the speed of light the slower time would appear to run, but since it's impossible to reach the speed of light given our current understanding of physics we can't go fast enough to actually stop it.

It's not that the object slows down or stops time, it's that time slows down or stops for the object.

Besides going to speeds comarable (but always less than c) in Special Theory of Relativity, time also dilates in a gravitational field according to General Theory of Relativity. A black hole is a body that is totally inside its Schwartzshild's radius (rs = 2*G*M/c2, where M is the mass of the object, G is the Universal Gravitational Constant and c is the speed of light in vacuo). If you're in a black hole, time will freeze.

When you go into a black hole you afterwards experience imaginary time.  I mean, your particles would after the get shipped off to a bu.

What do you mean by imaginary time? When you cross the event horizon, nothing significant will happen according to you. However, an outside observer will see you freeze at your final point.

But, the gradient of the gravitational field around a black hole is so large, that you will probably be streched like a spaghetti - Chris Spaghetti, that is. :)

Yeah, I heard that when you reach the event horizon of the black hole, nothing seems to be happening to you.  However, in the observer's view, time has stopped for you.

According to Stephen Hawkings, particles that enter into a black hole go into a baby universe which operates in imaginary time (which is a direction of time at right angles to "real time.")

Important to note that the current theory of physics is that it would take an infinite amount of time before event horizons would form at a black hole.  They are purely a theoretical idea, and our current model suggests that they couldn't actually exist (see the recent work of Lawrence Krauss).  It's also important to note that Einstein's theory of relativity does not say that time would slow down as you approach the speed of light.  If you were wearing a watch and travelling at the speed of light, the watch would continue to tick at the normal speed.    As the theory suggests; time is relative.  You can't say that it slows down or speeds up.  Things that are moving slower to your speed would appear to you to experience time differently; but if they were wearing a watch, their watch would also appear to tick at the normal speed; for both people time would be moving at the same rate; it would just appear to each other that the opposite person is moving through time differently; not that time itself is slowing down or speeding up.

As far as we can it is impossible to freeze time.  Just like it's impossible to "freeze" height, width or depth.

Agreed.  To freeze a specific dimension liek height, the object must externally and internally be at absolute zero.

Yes...technically...But no, not really. While approaching the event horizon of a black hole (presuming they exist), Stephen Hawking describes that to others, if you were on a live video feed, you would appear to slow down more and more until you actually reached the event horizon, where you would appear (to those outside of the black hole) to be frozen in time. To you, however, it would simply appear as if time was moving normally for you, and everyone on the other side would appear to be moving ridiculously fast, until you reached the event horizon, when everybody would pretty much be moving infinitely fast, and you wouldn't be able to see them.


Practically, though, it's not possible.

Yeah again, important to note that the "classical" black holes that you're talking about, with singularities and event horizons probably don't exist; that's the current physics model.  If they did exist maybe that would be possible, but at this stage the general consensus is that they do not.

Freeze time? Anyone care to point out how time is anything other than a subjective measurement?

Do you mean freeze time, like, in the way that Bernard did it in 'Bernard's Watch', or in 'Click'?

and as far as I know, time is only a measurement of something, so can that be frozen? I mean, you can't freeze, say, centimeters or kilograms...

...I think they're poor examples. Damn. :-\
