Now, would this space-time be curved by gravity? toe universe's mass?

No i dont believe there is time outside of the universe nor space but in other universes there CAN be space and time. but one does NOT imply that the other also exists there can be space without time (a universe that has space but no interaction) and time without space (a universe where interaction takes place without spacial dimensions). If universes like this exist is open for debate but we must leave the possability open until observations can be made that can state otherwise.

Space can only exist without time (and time without space) if there is absolutelly no object in it's domain.

In the moment there is something, there must be both time and space. The problem is that whent here is nothing, there is no time (interaction). I'm not sure about space without nothing existing...

I am convinced that time travel is impossible. I have my own reasons to believe it but if you happen to be adreamer and love sci-fi you will be upset about it.

So... keep dreaming my good friend.

Here at TOE quest, you must justify your position on why you maintain that time travel is impossible.

ps. has it not been the case that sci-fi always comes true??

[AntonioLao]

time travel can become theoretically possible only for observers but not as participants. By participants, i mean able to alter the course of history if traveling back in time. As an observer, all one has to do is to catch a photon and extract all information about the past and the future. To overtake the speeding photon, one needs superluminal speed. For an idea of just how fast a photon is: in just one second it reaches the moon.

Time
Space



which one of these actually moves?

I am going to start a new thread because i'm new here and it took me an hour to read yours
although it will be bassed along the same lines i'm sure you have a clearer way of phrasing your original paradox by now and that you may even have changed your mind on some issues as the replys have been very convincing

it is all a daunting as a new commer to the forum

[Casey_deJong]

i am of the opinion that energy equals time thus the faster we move the more energy we exert thus the quicker we age

Guille's time paradox is ultimately misleading (sorry Guille). Time is a congruence of spacial dimensions and measures the relative location and speed of mass carrying objects within the 3-dimensional spatial arena. Saying time is a dimension relies upon the ability of the reader to differentiate between a spacial "dimension" and a "dimension" that is not spatial.

For example... without the time dimension it is possible to give all the information about the position or locality of a mass carrying object within a 3-D space, but it is impossible to say anything about its speed (its change in position over time). When we introduce the time dimension, we can measure more of the speed, but the measurement of location becomes proportionately more difficult to specify (Heisenbergs Uncertainty Principle). The notion of a time dimension must therefore be dependant upon the number of objects relative to the object that is measureing time within a 3-D system. There SHOULD be a quantum mechanical explanation of why time is relative to the amount of matter within a given system (a solar system or planetary system, or even a galaxy), but I would say that the most important principle here is that time can only be measured concerning the relative speed and location of matter (or mass carrying objects). Time dilation and the slowing/speeding of time does not , for example, effect the speed of light. I would argue that this is because light does not actually have speed in the same way that an object with inertia has speed (a mass carrying object). Anomalies travelling at the speed of light simply have a direction vector coupled with a complete lack of location. If you consider the Heisenberg Uncertainty Principle, you should note that a complete lack of location would result in the absolute maximum speed possible, and in one specific direction (vector).

From this standpoint, time is the way that massive objects interact with the spacial dimensions around them. To put it another way.... time is like a perspective dimension of a given 3-D spatial system (galaxy, solar system, planetary system) that has significant amounts of matter.

lets think about guiles time paradox for a minute

Time needs time to be a dimension

ok what if time was not a dimension of its own but a property of a dimension

the dimesion in which we and our universe exists.

how is it that helpful?

It stops us looking for answers in the past.

i think that Time travel is not possible at least going backwards seems impossible. yet if people think it is possible then they will constantly look to what they could change. the problem being that the first person to go back in time if it were possible would destroy the life of billions just by arriving assuming of course that they aren't institutionalized for saying they are from the future.

the space time continueum
Perfection and ballance are key to the univese in which case so is harmony
for time and space to exist in the same place at the same time they must be the same thing.

eg. h20

Both exist Hydrogen and Oxygen creating Water a liquid much denser than either of the origonal components
as a matter of fact oxegen and hydrogen are invisible on there own.
How do Time and Space come in to it?

Imagion a ball of liquid floating in space!!!

now in the center of that ball inject some air what happens?

now what if the ball was bigger?

no! much bigger like the size of our universe big.

Imagine the liquid was heavier than the densist of ellements due to its enormous size but in small quantities it is no heavier than heillium.
Injecting air of for that matter any thing in the center of this ball would result in bubbles rising or traveling towards the outer surface this at least can be considered when trying to describe why the universe seems to be constantly expanding. also why id didn't collapsse due to gravity a moment after it was created in the throws of a big bang or oterwise.

True. Sci-fi books gave us the idea of robots much before we were able to invent them. Now it is a whole industry. Sci-fi first thoguht the idea of travell through wormholes. Now many scientists agree it to be possible. There are more examples.
