Yours. I would've quoted you but wii internet can be dumb.

Get in a spaceship, travel away from the earth at some fraction of C, turn around, come back at some fraction of C. More time will have passed for those on earth than for you. You will have travelled into the future. 5 years go by for you, 50 go by for everyone else.

I guess I should have elaborated clearer. Traveling -back- in time was what I thought he was referring to.

Time travel is possible without exceeding the speed of light. We can get to the future without "beating our image."

Yeah, pretty sure time travel to the past isn't really feasible by science as we know it (unless....can we slingshot around the sun?)

Re: Time (and existence)

Well yes Devonin, it is most likely that time travel into the past isn't possible. As I pointed out earlier, Space can be equated to time, because time is a property of space, so if you wanted to travel back in time you'd have to reverse space, and I'm not sure this makes sense to anyone here. I mean, it's the same reason why if you went into the future using the method you described, you aren't coming back.

Time travel is possible without exceeding the speed of light. We can get to the future without "beating our image." But really, study the theory of relativity; you will learn that you can never beat your image, because no object can be observed to be traveling fast enough to beat its image.

You can beat your image to a destination, actually, if I recall correctly, using quantum entanglement techniques. Photons can be blasted through cesium gas tubes, and those photons appear to reach the end of the tube before even leaving the start, with measured velocities of more than 300 c.

However, none of the photon packets ever actually travel faster than the speed of light. No time travel occurs. The reason we observe this effect is because of quantum effects at the level of the photon, distorting it's behavior in the cesium medium. The phase velocites never exceed c, though. Very cool 8)

Re: Time (and existence)

well, what is heat?? heat is light in the infrared spectrum,meaning, that we, humans emit photons. and photons are sub-atomic particles sped up to the speed of light. yes, they gain infinite mass,but in doing so they become light, and when they vibrated they create what we call heat. and what i mean when i say we manifest it, i mean simply that time is the passage of events. we put a label on it, we try to measure it, time is nothing more than a word we made up. allit represents is the passage of micro events everyday through our five senses.

Re: Time (and existence)

well, what i meant when i said that was that the general consensus of time travel is nothing more than beating your image. and yes, obviously it can't be recorded, because you can only record the image. the closest thing we could get to time travelling is going out on a spaceship at sub-light-speed, then turning around. you would arrive some time in the future at a later period than the time you spent on the ship. sorry, i didn't think i would run into a challenge

Re: Time (and existence)

I find it fascinating that some people here are actually trying to argue against the laws of physics.

Also, since I am inexperienced and probably stupid I'll give my two bits based off of my experiences and observations. If I'm wrong someone correct me ASAP.

Time travel to the past is not feasible (and barely plausible) because it contradicts the definition of time. In order for time travel to be possible, we have to assume that there are 3 dimensions of time (imagine a timeline as 1 dimension of time), or else there is no way to jump from one point to another. However, we can bend time slightly to make it appear as if we were traveling into the future. This is definitely plausible.

EDIT: wow I should've read the freaking posts right before me all I did was state was already said wonderful

Re: Time (and existence)

The first three dimensions don't really exist let alone an actual dimension of time. Just because as people we claim an object to have a height and a width doesn't mean that the object actually holds that property outside of our own understanding of what height and width should be.

[cooke71892]

Re: Time (and existence)

outside our understanding is something we will never understand. and why doesn't it?? even if you draw a dot on a blackboard it still has the weight if the chalk dust, and in the space time continuim it holds a minute width and length. if not then there would be absolutely nothing, and if that were the case, this conversation also would never have happened.

[Izzy]

Re: Time (and existence)

Length and width aren't actually things beyond our own definitions of them.

[cooke71892]

Re: Time (and existence)

they are in quantum terms. you see, length is but what we make it, it is the total mass of a line going any given distance throughout space-time. i say mass because the longer the line, the heavier
