Time_Travel Posted January 16, 2011 Report Posted January 16, 2011 If i were in a black hole( i know nothing can live in a black hole except the matter that it has swallowed) would time::1. Totally Stop2. Time would tick negatively3. Time would tick slowly. Just thinking theoretically what might be the answers even though they are subject to speculation.My guess would be 3 but thats just a guess Quote
Alpine Posted January 16, 2011 Report Posted January 16, 2011 Hmmmm....... I guess I could give this a go. Please excuse me if my theory seems to be irrelevant, but I'm just 15. Anyways, I wold go with none. It is impossible for time to actually stop. We cannot actually admit that time would stop in a blackhole since no one has actually entered a black hole. :PSo, saying that either of the three conditions would apply to it. Though what I say might not be applies to it either. If you were in a blackhole, while the time in it would stop / become slow / move in negative motion the time in rest of the universe would go as usual (except in other blackholes).Other than that, we humans use time according to the Sun, so time differs from star to star due to their different speed and size which makes it silly to use the sun's speed as a default for determining time. Other possible theories, according to my imagination would be that blackhole are like the hyperbolic time chamber (as shown in DBZ), where the time on Earth runs as usual but inside the chamber, the 24 hours of Earth are 365 days inside the chamber, so something like that is possible. :) Quote
CraigD Posted January 16, 2011 Report Posted January 16, 2011 If i were in a black hole( i know nothing can live in a black hole except the matter that it has swallowed) would time::1. Totally StopAccording to General Relativity, a theory that’s to date has been confirmed in every experimental case, at distance [math]r_0 = \frac{2 G M}{c^2}[/math] (known as the Schwarzchild radius) from any non-rotating body of mass [math]M[/math], the time measured by a clock at that position totally stops relative to the clock of a distant observer. For most bodies, such as planets and stars, [math]r_0[/math] is smaller than their radius, so you can’t reach that position, as the mass would no longer all be under you there, but mostly over/around you. Only very dense bodies, such as black holes, have radiuses smaller than [math]r_0[/math], so can produce in this “time stop” effect. Read about this at any good textbook or encyclopedia article on the subject, such as the wikipedia article gravitational time dilation. For a good science fictional treatment, read the classic 1977 novel Gateway. While it’s true that star-mass black holes have such sever radiation and tidal effects near their event horizons that nothing made or ordinary matter could survive there, for hypothetical gigantic ones like the supermassive black holes which appear to be at the center of every Milky Way-like galaxy, this isn’t necessarily true. Solving the tidal force equation[math]F=\left( \frac1{r_0^2} - \frac1{(r_0+L)^2} \right) G M m[/math]for a body length [math]L= 2 \,\mbox{m}[/math] with mass [math]M= 50 \,\mbox{kg}[/math], representing a human body at distance [math]r_0[/math] from a large mass [math]M[/math], we find a human-comfortable tidal force of about 1140 N (about the same as hanging by your arms from a tree limb) at the event horizon of a [math]6 \times 10^{34} \,\mbox{kg}[/math] (about 3 million solar masses) black hole. So, if you could handle the environmental nastiness – mostly lots of dangerous radiation – and the space travel problem of getting there, you could fairly easily stop time by traveling to near our galaxy’s central supermassive black hole.

Time_Travel Posted February 10, 2011 Author Report Posted February 10, 2011 Does time runs slower on Earth than in Empty Space....I believe yes as Earth is having mass , where as Empty Space doesn'tDoes this mean i age faster in Space than on Earth Quote
Little Bang Posted February 10, 2011 Report Posted February 10, 2011 Time can never stop. The rate at which it moves can approach zero but never reach it. Quote
Time_Travel Posted February 10, 2011 Author Report Posted February 10, 2011 Time can never stop. The rate at which it moves can approach zero but never reach it. Is that the assumption (of yours) or proved, since this raises a lot of contradictions. Quote
Little Bang Posted February 11, 2011 Report Posted February 11, 2011 If time slows as it goes deeper into a gravity well and the mass of a black hole approaches infinite density then time could never stop even if all the mass of the Universe was in a single black hole. That conclusion requires only logic. Quote
Time_Travel Posted February 11, 2011 Author Report Posted February 11, 2011 The problem with this Logic is Time itself.Time was created when Universe was born with a Big Bang, even space was born with it,this is an universally accepted Logic.If time never stops no matter what like your logic says then the Universe must have existed forever.But strangely Universe was created with a BB.It means time was also created with a BB. This leads to a Logic that Time wasn't there before BB.So it raises a question whether time can stop, for instance before BB. This also raises another interesting Logic if it is correct. Any place we see where time stops may well be a possible BB in happening. Quote
Little Bang Posted February 11, 2011 Report Posted February 11, 2011 Agreed, for our Universe there has been time since it's beginning but as long as there is matter or energy there will be time. The original question's answer is that time does not stop but ticks slower as it approaches the center of a black hole. Quote
Time_Travel Posted February 11, 2011 Author Report Posted February 11, 2011 Apology for straying bit off topic(may should ask it new topic). It ticks slowly in Black hole but never approach zero even in a black hole.But does the laws of the black hole allow time to tick?? Since all laws of known physics collapse/fail in Black hole including space and time... Quote
Little Bang Posted February 12, 2011 Report Posted February 12, 2011 Time marches on, no matter where. Quote
Time_Travel Posted February 12, 2011 Author Report Posted February 12, 2011 Time marches on, no matter where. "Time marches on no matter where", This statement has a direct consequence on Big Bang, no matter what.Time wasn't present before Big Bang and was born with BB as a generally accepted theory. If above statement is correct then where to did time marched before Big Bang, not forget that time was created but never existed forever Quote
Qfwfq Posted February 12, 2011 Report Posted February 12, 2011 Time marches on, no matter where.Of course where doesn't matter, because it doesn't make sense. If When is Where,Then Where is When.And Where is When,When you need Where?:lol: Quote
Little Bang Posted February 12, 2011 Report Posted February 12, 2011 Time, you have made the assumption there was nothing before our Universe started. The mainstream has made that same assumption with no logical explanation of how this is possible. How do you create a Universe from nothing. A logical guess would be an electric field sense that is what comprises the electrons field and matter can be made from that field. The frame of reference for time is infinitely slow or infinitely fast. Quote
Time_Travel Posted February 13, 2011 Author Report Posted February 13, 2011 Time, you have made the assumption there was nothing before our Universe started. Little Bang, there is no assumption involved in whatever i said. Right now the only perfect explanation for the observed data is Universe had a beginning. Scientists don't spend billions of dollars to come to a conclusion and we say that as an assumption?? Is it fair?? (Off course they can still be wrong, as the Universe throws something else to the earlier observed data, but until proven wrong we have to trust the observed data). How do you create a Universe from nothing. http://www.telegraph.co.uk/science/science-news/7976594/Stephen-Hawking-God-was-not-needed-to-create-the-Universe.html According to Stephen Hawking Universe can and will create itself from nothing.He also states that Spontaneous Creation is the reason there is something rather than nothing. http://arxiv.org/abs/1011.3706v1As this article suggests , Roger Penrose says WMAP Concetric circles data suggests violent pre Big Bang activity.You may be right too, as this article suggests that there was something before BB. As the Universe expands at an accelerated state Time moves faster and faster on an average on all parts of the Universe may be an exception is a Super massive Black Hole and heavy objects, but eventually even when they too die by giving out radiation or getting ripped by Dark Energy time will move there too faster. But the question is, is there a black hole or place in Universe where time stops absolutely to zero. Black hole might be a possibility as Light itself can't escape from it , and anything powerful enough to over speed the speed of light will have time reversed or at least halt it. Quote
