This guy claims hes from the future, put " john titor " into google and theres loads of links about him, he provides pictures of and how his time machine works!

Believeing if it's true is up to you.

WOW cool

These douches actually believe him?

These people lack a few braincells.

hmmm- interesting i must inquire of him- he is either ingeniouse or crazy

i like him he sounds funny

anyway just a loada bulls***

i'm curious on how time (an immaterial thing messured in a series of events but accually an ever going constant) can be altered and even controled by gravity (another immaterial thing that acts like a magnetic pull for objects of lesser mass to objects of greater mass but no effect on a series of events {though might cause some}) i think something is not right here.

well if 3bn. people die in 2015 then hes really a clever guesser or time-traveler

just leave this topic open for the next 10 yrs.

not going to happen

i looked up his name and read about him, and while i doubt that he is realy a time traveler, some of the things he said will probable come to pass.

3billion people dieing due to nuclear war- as long as we have nuclear wepons we will eventually get into a nuclear war which will cause lots of death.

medical care will diminish- he said in 2036 if you get a disease doctors will just let you die, doctors concentrate more on broken bones and stuff of this matter in order to stregthen the gene pool which will eventually be needed concidering the large ammounts of peole who live that have "bad" genes and are dirting up the gene pool.

People will become more focused on religion- if we do get into a nuclear war (which is inevidable) then people will probable resort to religion once more. Look what happened on 9/11 everyone all of a suden became all religiouse, a nuclear war will probable have the same effect only to a greater effect.

Very true Tzobell.

I think this guy is on drugs or trying to get attention for huimself due to some psychological disorder or something though.

Time travel is purely a philosophical concept. Time is just a emasurement of change like meters can be used to measure length and width. You aren't going to change everythign around you to a different ordered state just as you can't eradicate the 3rd spatial dimension from existance.

i think that time travel is a philisophical concept, but my religion actualy believes that when you die you will beable to go back see anything from the past, i dont know about the future though. To a lot of people it may sound crazy, but if ya read the bible there are numerouse prophets who saw everything that ever happened so its realy not that far fetched if you believe in the bible.

Well, time travel exists in that, you can make something experience time more slowly, Like, approaching the speed of light and such. But, you can't undo it.

We define time travel to mean departure from a certain place and time followed (from the traveller's point of view) by arrival at the same place at an earlier (from the sedentary observer's point of view) time. Time travel paradoxes arise from the fact that departure occurs after arrival according to one observer and before arrival according to another. In the terminology of special relativity time travel implies that the timelike ordering of events is not invariant. This violates our intuitive notions of causality. However, intuition is not an infallible guide, so we must be careful. Is time travel really impossible, or is it merely another phenomenon where "impossible" means "nature is weirder than we think?" The answer is more interesting than you might think.

i get a magazine called DISCOVER magizine, they did a special on einstien, and one

of the things they went over was time travel. time is like a cone

---------------

---\000000/ <--- future
------\000/
-------\0/
-------/0\ <--- you are here
------/000\

to escape the cone, you would have to go faster than the speed of light. since the

speed of light is relative, something would have to happen to allow you to exceed the

speed of light, then (theoreticly) you would go like this

---------------
\000000000/

or

einstien (nor anyone else) was never able to find evidence that time travel could not

happen, so in theorey, it could work

NOTE: this information might not be correct, this is only from what i remember off

the top of my head

yes, i have read up on that as well. Its enstiegn theory relativity. the faster you go the more time slows, if you were going the speed of light it might take you years to bend down and tie your shoe but it would seems like a few moments to you. Time travel into the future is possible, its uneconomical but not immpossible.

yes, but travelling back in time is a differnt matter..

I have a time machine in my garage.

then again you have to concider that it is uneconomical as of 2005, though i seriously

dought(sp?) this guy is actually from the future, at the exponental rate of scientific

discovery in the past 1000 years, im guessing its possible in the next 4000-5000

some new form of energy will come out that will allow man to further explore the

boundries of science

Perhaps, but I can imagine that travelling at near the speed of light would require huge amounts of energy, amounts we can scacrely imagine. Attemtping to break the limit, you'd have to do something really fancy with physics, reverse the effects of intertia of break something down into some state less definable than matter and energy; something would require vast amounts of energy if possible at all.

i was reading at johntritor.com that some scietist said its possible to creat mini-black holes that could enable you to "time travel"

he said he created a mini-black hole in a fireball, too. That's nifty. I think it's totally possible to time travel, but why haven't we seen any yet? I mean, it could go in the past if it could go in the future...

if time travel into the past was possible then why havent we had anyone official tell us from the future. Some guy on the internet dosent cut it.

past time travel isint a good idea in my book, whats done is done, and what could

happen should these things not have happened . . .

its bad stuff messin with whats been done

It sounds creepy, but impossible.
That guy is just a SUPER attention whore

Well is you travle back in time then your gonna end up messing up the timline completly and may end up with you never being born. I highly dought that time travel is even possible.

And if you create even a mini black hole you would get destroyed when you enterd into it. But as you are moving into it you will find time will slow and eventualy freez then you will get obliterated when you go further in.

Also traverling at the speed of light is imposible.

the guy who claims he travled to 2036 was drunk, I bet.

That's creepy. He said there will be a US civil war this year. If that happens... it might be real. But I'm not beleiving it until I see civil war.

I think hes crazy....

I belieave this guy I mean Someone said that he created a mini black hole Well even if you did go through a black hole then you would be turned into a piece of spaghetti(Spell) (Doubt there you go oozie).

But what I said in Time travel topic was not to travel the speed of light but to slow it down there are a lot of materials that slow light down such as ice water.

<grammar whore> Sephiroth, learn to use this little piece of punctuation: "." It is called a period, and it comes at the end of each sentence to signify its completion. </grammar whore>

As for time, it flows in one direction and one direction only. Forward. To travel back in time is the temporal equivalent of swimming upstream in rapids... during a storm of the century... times a thousand. What is very possible, however, is the concept of travelling into the future. As any sort of matter approaches the speed of light, it experiences a unique effect known as time dilation.

As for light, it is said in the physics world that the speed of light is CONSTANT (c = 299 792 458 m/s). However, once we start getting involved with relativity, the whole situation just gets so much more complicated. Everything becomes relative to a specific frame of reference. When one approaches (but does not reach) the speed of light, he/she experiences the world in normal time. However, while one second may pass to the person who is moving, one standing on a street corner may experience 5 seconds. This person would appear to be moving at five times the normal rate for humans to walk, breathe, etc. Invariably, this is considered travelling into the future.

As for travelling at light speed... it is not possible. When one hits exactly the speed of light, a phenomenon occurs wherein they experience the entire lifespan of the universe in an instant, before ceasing to exist. Here is why. The equation E=mc^2 is a simplified version of the true equation. It is actually E=(mc^2)/(1-(V^2/C^2)). What this means is that as "V" increases to a significant fraction of c, the bottom part of the fraction approaches zero, which invariably makes a VERY VERY LARGE number. This means the energy required to travel at the speed of light is infinite. Also, were you to travel at the speed of light, the equation would look like this: E=mc^2/0. For any math geek out there, you will know that we cannot divide by zero. That equation is undefined.

Curious enough, though, according to the equation we CAN travel faster than the speed of light. To do so, however, we would need to use up a negative amount of energy. It is possible to do so, according to the equation, but one cannot accelerate through the speed of light in order to achieve those speeds.

So to sum up a rather long-winded spout on Relativity (Gr. 12 Physics): No, one cannot travel backwards in time without exceeding the speed of light and never actually reach the speed of light. At that point (according to the equation for time dilation), time DOES start to move backwards... I think... Gah, so long since taking that class...

Thanks Rion of fire for your little lesson on periods. I do belieave I used them.

Anyways I guess he was trying to show off because he knows what e=mc^2 means. Maybe the dim wit didn't understand what I was saying.

We all know the speed of light in a vacuum is constant,But light slows down when travelling through a medium. This doesn't make much difference when it is travelling through air, but it does make a difference in many other media. For example, light going through glass slows down to 2/3s its speed in a vacuum. Just like it's harder for a person to move through water than through air photons (massless particles that make up light) move slower when going through a medium that is difficult for them. Certain states of matter slow light down a huge amount and by using these states of matter, scientists can slow light down to a "human" speed.

It is possible to reach the speed of light. If you were to go the speed of light you would not know it. Its the accelleration of the object(Being us) that we would notice not the speed.

For your e=mc^2 comment. Relativity tells you your invariant mass is zero, and so is the passage of your proper time; you don't have a rest frame in that case. So you would not cease existence.

Why, you speak as if you have some sort of knowledge of physics that has not been discovered and used for decades. Have you derived a better formula that shows that travelling at the speed of light is possible? According to E=(mc^2)/(1-(V^2/C^2)), once one hits the speed of light IN A VACUUM, well... you can't. It just cannot be done, according to the combined knowledge of all of the physicists in current existence. Agreed, you do not cease to exist. You simply cannot achieve the speed of light in a vacuum.

Sure, one can slow down light. That does not change the constant c, which is the speed of light in a vacuum. That is the number that is used in the equation E=mc^2. Time only begins to slow down according to the frame of reference that is doing the travelling once its speed is a significant fraction of c.

Hell, if I was able to slow down light to a walking, or even running pace of a human, that does not change the value of c. That does not allow me to "run back through time". It would be one hell of a trick, but it does not fundamentally effect time when viewed through the frame of reference of someone standing watching the beam move.

Again, yes. Glass does slow down the speed of light. I am looking forward to seeing the schematics for your transportation device that can travel through glass (or another solid form of matter).

Now for a personal note. Dimwit? Ouch, that hurt. And I do not appreciate such harsh words where none were called for. Show off? Probably. Thank you for pointing that out, with no sarcasm intented here.

<OCDness>You spelled "believe" wrong.</OCDness>

First off your the one that started with me.. Correcting my gramatic errors. I will tell you that im not the best speller in this forum but I don't hold the "Worst speller" In the forum title like gary.

I have not taken any physics classes yet. And I have not taken any Astronomy classes either.

I don't remember saying I was creating something out of a vacuum..I was using the "Light in a Vacuum" As a reference because its constant. Therefor its always going the speed of light.

I didn't wan't to use anything because light can slow down or speed up through other medias.

What I am saying is when light travels through glass its speed is cut 2/3 of that in a vacuum.

"Hell, if I was able to slow down light to a walking, or even running pace of a human, that does not change the value of c. That does not allow me to "run back through time". It would be one hell of a trick, but it does not fundamentally effect time when viewed through the frame of reference of someone standing watching the beam move."

...The value of c is what we are slowing down.. The speed of light would be the constant...If im correct. And We see into the past right now. When you look at the sun you are seeing light that was in the past. Roughly 8 light minutes into the past.
