Time Travel

A friend of mine sent me this rather interesting article about time travel. hehe

EDIT: i guess i can explicitly paste the link, cuz the link color above is about the same color as the background. http://tv.yahoo.com/news/wwn/20030319/104808600007.html

let me think................................no i don't beleive..........no wait, yes..........time travel?...88 miles per hour........flux capasitor......2.1 jigawatts....carry the 2... ok ok, i made up my mind......
this guy is from the future

Well, it would be nice of you if you'd post it or something...

Hehe, indeed very interesting, how long hast this story been around?

quote:

NEW YORK -- Federal investigators have arrested an enigmatic Wall Street wiz on insider-trading charges -- and incredibly, he claims to be a time-traveler from the year 2256! Sources at the Security and Exchange Commission confirm that 44-year-old Andrew Carlssin offered the bizarre explanation for his uncanny success in the stock market after being led off in handcuffs on January 28. "We don't believe this guy's story -- he's either a lunatic or a pathological liar," says an SEC insider. "But the fact is, with an initial investment of only $800, in two weeks' time he had a portfolio valued at over $350 million. Every trade he made capitalized on unexpected business developments, which simply can't be pure luck. "The only way he could pull it off is with illegal inside information. He's going to sit in a jail cell on Rikers Island until he agrees to give up his sources." The past year of nose-diving stock prices has left most investors crying in their beer. So when Carlssin made a flurry of 126 high-risk trades and came out the winner every time, it raised the eyebrows of Wall Street watchdogs. "If a company's stock rose due to a merger or technological breakthrough that was supposed to be secret, Mr. Carlssin somehow knew about it in advance," says the SEC source close to the hush-hush, ongoing investigation. When investigators hauled Carlssin in for questioning, they got more than they bargained for: A mind-boggling four-hour confession. Carlssin declared that he had traveled back in time from over 200 years in the future, when it is common knowledge that our era experienced one of the worst stock plunges in history. Yet anyone armed with knowledge of the handful of stocks destined to go through the roof could make a fortune. "It was just too tempting to resist," Carlssin allegedly said in his videotaped confession. "I had planned to make it look natural, you know, lose a little here and there so it doesn't look too perfect. But I just got caught in the moment." In a bid for leniency, Carlssin has reportedly offered to divulge "historical facts" such as the whereabouts of Osama Bin Laden and a cure for AIDS. All he wants is to be allowed to return to the future in his "time craft." However, he refuses to reveal the location of the machine or discuss how it works, supposedly out of fear the technology could "fall into the wrong hands." Officials are quite confident the "time-traveler's" claims are bogus. Yet the SEC source admits, "No one can find any record of any Andrew Carlssin existing anywhere before December 2002." Weekly World News will continue to follow this story as it unfolds. Keep watching for further developments.

Here's the part I don't get

"Carlssin declared that he had traveled back in time from over 200 years in the future, when it is common knowledge that our era experienced one of the worst stock plunges in history. Yet anyone armed with knowledge of the handful of stocks destined to go through the roof could make a fortune.
"

However at the beginning of the article it says that he made all those fortunes within two weeks. Now I donno about history-writing in 2256 but it seems somewhat unbelievable that they documented the developments of so many stocks that exactely..over such a short, specific amount of time..200 years ago.


Also, why make it complicated Mr. Future? If i had a time machine I simply would have travelled back to yesterday and "guess" the right lottery numbers, repeat so..if i become suspicious just travel back another 2, 3 weeks etc. But stock exchange? 200 years ago? This has nothing to do with the current crisis! If i know the precise development of stocks i can gain much money even in a relatively safe and prosperous era. what the hell...

its from yahoo, none of it is true.

yeah i just read that it was already confirmed to be bullshit. Another one of thos fucking internet myths

quote:

AN ALLEGED Wall Street insider dealer, arrested after making a fortune from suspiciously timed purchases, has come up with the weirdest excuse yet. Andrew Carlssin, 44, told the Securities and Exchange Commission that he was a time traveller from the year 2256, taking advantage of our well-documented market collapse. The SEC is, understandably, unwilling to believe him. �He�s either a lunatic or a pathological liar,� said an insider there. Such is the story, apparently culled from a number of news websites, doing the rounds of the City. Alas, it is merely one of the better internet myths. The SEC has never heard of Carlssin, and several �facts� are plainly untrue.

Yes, it was always bullshit. Simply an exaggeration.

I saw this on the news earlier as well

did you know that every time you fly on a commercial jetliner, you travel through time (its true, no bullshit)

WTF? really... pls explain!!! otherwise ur just babbling!

from the article...
"The only way he could pull it off is with illegal inside information. He's going to sit in a jail cell on Rikers Island until he agrees to give up his sources."

What if he doesn't? then what have they proved? they haven't proved squat.. he could be either telling the truth or he can realyl be just a nut...

This guy seriously as some interesting shit like the his space craft.. but tell me then, why make this shit up, seriously otherwise he's been watching way too much star wars reruns...lol

Hmm interesting... or maybe he just copied the idea of the Back to the Future dood and that book on horse racing...???

Yes time-travel to the past is possible, the tools you would need to make a time machine that could travel into the past, are quite similar to those you would need to travel to the future. The main thing is you would need to be able to travel at the speed of light. However unlike traveling into the future, rather then moving in a straight line, you would need to be rotating at the speed of light. You would need a "vessel" about the size of a carousel rotating and when it hit the speed of light, the gravity would be strong enough that it would actually bend time enough to make it reverse. Read up on Einstein's special and general reletivity for more info, also I recommend reading Steven Hawking's A Brief History or Time if you are interested.but in any case if all of you abide by the laws of physics, then most probably time travel does exist because it is clearly defined in Einstiens general reletivity (or maybe it was in special reletivity, can't remember) I urge you all to read A Brief History or time, it's clear enough so anyone can understad it

It's true it's true... The closer an object's velocity is to that of light, the slower time passes for that object and hence, it travels into the future. This is easier to illustrate with the follwing example made famous by Einstein. Say you have twin brothers. One of them decides to board a super-fast spacecraft. He travels near the speed of light and takes a tour of the solar-system. Although maybe 1 week has passed for him, several years would have passed on Earth and upon his return to the planet, his brother will be older than he is and he will effectively be in the future (for him).

This has been proven too. I don't know the exact details of the experiment but it was something like this:
Two atomic clocks (precise to tiny fractions of seconds) were syncronized. One was put in a supersonic jet while the other stayed on the ground. The jet went for a run and then came back. The clock on the jet was slightly behind the clock which had remained (relatively) stationary. And so the real time travellers are astronauts who, by virtue of the (relatively) extraordinary speeds at which they travel while in orbit, will have travelled a few seconds into the future by the time they return from their missions. Fascinating stuff.

As for time travel into the past, I always thought one would have to travel faster than light which is impossible as far as we know.

Another point that I find interesting has to do with black holes. It is impossible to die IN a black hole. This is because as you approach the "hole," gravity becomes so strong that it slows down time until time will eventually stop. Therefore, if one were to be sucked into a black hole and survive the intense radiation surrounding it, time would slow down so much that you would never reach the "hole". Weird.


How to build a time machine:

If you possess some sort of technology that enables you to manipulate wormholes, put one near a high gravity body such as a neutron star or a black hole and put the other one somewhere else. Time will pass more slowly at the wormhole's exit in this case so all you have to do is hop in and there you go, time travel.

i was just wondering (all this came from public schools in california )
When u are in a boat going 10 mph, and the river is moving with u at 20 mph, then you should be going 30 mph. If light is traveling at C speed, can't u just blow (with breath) into a a beam of light or something and make it go C+N (n is the mph of your blow) MPH? light going faster then the speed of light...... ?

Your assumption is wrong because the boat example is flawed. If the speedometer of the boat reads 10 mph, then the boat is travelling at 10 mph no matter what the velocity of the river current. It's the same as for a car. The speedometer says 50 mph even though the Earth is rotating much faster than that. To accelerate the beam of light, your breath would have to travel faster than the beam.

First of all, just a little clarification, you would have to travel faster than light to go into the past. But the problem is that to reach the speed of light you need an infinite amount of energy, so you can never gain that speed. You can bend space using warp fields so that from the outside it seems like you're traveling faster than light, but on local scale you're still going slower than light and are unable to travel into the past. Traveling faster than light, however, doesn't requre infinite amounts of energy, but to travel faster than light you'd first need to break through the light barrier, which now seems impossible. Although, while faster than light travel doesn't require infinite amount of energy, it brings complex numbers into the equation. So you start travelling backwards through time, but not through our time, rather through a different time perpendicular to ours (dt=dt0/sqrt(1-b^2)), b=v/c. If v>0, b^2>1, dt=dt0/sqrt(negative number), dt=dt0/i*k (k is an irrelevant constant number), dt=dt0*(-i)=-dt0*i.

Now, about the boat, when you're moving 10mph, and river is moving 20mph, you are moving 30mph relative to the earth. But, that only works for low speeds. As you get near the speed of light, speeds don't add up linearly anymore, and c+c does not equal 2c, instead, c+c=c (c=speed of light). So if one object is moving away from you towards the east at the speed of light, and another one is moving away towards west at the same speed, although it looks like to you that they're moving away from each other at twice the speed of light, each one sees both you and the other object moving away from it at the speed of light. That's because time flows differently on all 3 systems. Sounds crazy but it's true.

I'm in sort of a hurry now, but if you want, I could explain both things in detail.

Drug Tito..interestng point you mentioned in the first paragraph. Also...there are something in the theoretical world called Worm holes I did a paper regarding time travelling..so I got some time to type this whole blurb on it about wormholes.
A Schwarzschild Worm Hole(or Worm Hole for short) is a geometry of four dimensional space-time( 3 dimensions of space and the 4th dimension time) in which two regions of the Universe are connected by a short narrow throat. This event was discovered when Karl Schwarzschild determined a geometrical relationship of empty space surrounding any spherical mass with respect to space-time within a few weeks after Albert Einstein published his paper on The Theory of General Relativity. The Schwarzschild metric equation that describes this is
ds2 = - ( 1 - rs / r ) dt2 + ( 1 - rs / r )-1 dr2 + r2 do2
The quantity ds denotes the invariant spacetime interval, an absolute measure of the distance between two events in space and time, t is a `universal' time coordinate, r is the circumferential radius, defined so that the circumference of a sphere at radius r is 2 pi r, and do is an interval of spherical solid angle. But under certain circumstances, the Schwarzschild metric can yield to a negative square root as well as a positive one, showing that an imaginary representation of the geometric relationship. This gave birth to the concept of a wormhole. A classical large scale wormhole is a solution to Einstein's field equations, which governs the curvature of space-time. The most unique feature of these wormholes is that they could provide relatively easy means of travelling to distant regions of space, or even travelling backwards in time. The problem with a macroscopic wormhole is that it is not a static structure. What that means is that the wormhole can expand from a zero throat radius to maximum radius and back within few moments of time, so fast than even light cannot enter it. In order to maintain the maximum throat radius of the wormhole, it would need to be 'fed' with matter containing negative energy density. Such matter does not exist to our knowledge and is often referred to as exotic matter. Although we do not know how to obtain exotic matter, we have several indications that such matter may exist. For example, between two metal plates there can be field fluctuations that have negative energy density relative to field fluctuations in a free vacuum. Evaporating black holes also show negative energy density. But to obtain a finite amount of negative energy density matter is a far road ahead in terms of experimentation. However, just recently a new light has been shed on this topic. According to a Russian theorist by the name of Sergei Krasnikov, a wormhole may large and stable enough to conduct intergalatic travelling. He came up with an equation that shows that his wormholes can create its own abundant supply of exotic matter, allowing the wormhole to feed off this and making it possible for entering and exiting. But, this is still up for discussion as the theory is still fresh and many physicists are working on it to get some possible progress or to be able to refute the claim. With this in mind, we can understand that this technology may be possible in the future

frame of reference
hard concept to grasp is the CONSTANT velocity of light regardless of the frame of reference.


But a question I was wondering about. If travelling at light speed would halt time to zero for that indefinite period of travel, would it take no time at all for light to reach its object?
If so..why do we have the the units "light-years"..obviously referring to the distance in which light travels per year. Wouldnt that value be infinite?

Sorry about the science lecture..im getting CTS now

toodles

Travelling at light speed slows time to a halt only for the traveller. The rest of the world still functions normally. So while it seems to the traveller who's going at light speed that no time passed at all, the time flow hasn't been altered for the outside observer who sees the traveller's speed as finite and equal to c.

back to the article itself
here is a piece on the story

http://www.timesonline.co.uk/articl...-627115,00.html


and do you know what the weekly world news is? it is a tabloid. if you think this may be remotely true just look at their web page and see some of the other stories they are reporting.

Wow this is a realy cool topic..... Id rather see post with this kinda stuff instead of war politics bs or dot threads for that matter..

ahh, makes sense thanks man

I second that

Mack & DrUg_Tit0 id love to have a smoke with u guys

yes, it is refreshing to see some intellectual posts rather than the likes of a dot thread (18 pages long) even if i don't understand it all


you guys study physics and maths at college?

are there any theories to what happens when u enter a black hole? what is the different betweeen a black hole and a "wormhole gate"?

quote:

Originally posted by djSlain are there any theories to what happens when u enter a black hole?

according to general relativity, gravitation severely modifies space and time near a black hole. as the event horizon is approached from outside, time slows down relative to that of distant observers, stopping completely on the horizon. once a body has contracted within Schwarzschelt (sp) radius, it would *theoretically* collapse to a singularity (dimensionless object of infinite density)

Originally posted by djSlain what is the different betweeen a black hole and a "wormhole gate"?

some astronomers believe that when u travel through a black hole, u go through a tunnel callde a wormhole where u are changed changed into pure energy (according to einstein.) then u come out of a so-called white hole. if a white hole exists, it should be asmall body in space that sends out a lot of pure energy. other astronomers believe a worm hole is a portal to other univreses. they believe that matter changes going through a black hole and creates a new universe with its own spacetime continiuum.

in other words worm hole = tunnel to a white hole at some other point in spacetime

if your reference point is the shore, then he is correct, the boat is going at 30 mph
