When you travel at the speed of light, there is a large amount of energy being transfered through you. This means that your sense of time will slow down drastically beacuse your now dealing with much more input (reminds me of CCMU lag...), but it does not mean that if you go faster you go backwards. There is no limit to how slow you percieve things.

Just wondering if anyone has any objections or different points of view on the topic. Personally, I think it's impossible.

Ya, it's impossible. Even IF it is possible, who says we're ever gonna find out how to do it? We have a 100,000 times better chance of proving wether a god does or does not exist, then we do having the ability to go back in time. That's all I'm saying.

I really think it's impossible. If it were..then the space-time continium would be in some sort of chaos.

Theoretically it is impossible as stated by Einstein's Theory of Relativity.
Einstein proved that the faster you go, the slower time goes until you reach the speed of light in which time completely stops.
Einsteain also stated that the speed of light is the Universal speed limit for both Matter and Energy.

So therefore theoretically it is impossible go faster than the speed of light and therefore you cannot go back in time.

Yea, it is impossible to go back in time, But i'm not sure about going forward in time.

Going forward in time is also theoretically impossible.
Because you can't just go in reverse and do the opposite of what Einstein said. Speed is a factorial factor with an absolute magnitude and with direction.

A Wormhole would be the nearest scenario in which you go "around" the time-space continuum.

Forewards in time is easy. go at the speed of light, everything around you will go faster through time then u do. Backwards in time, i have no idea. It's probably somehow possible. Maybe u have to go in reverse at the speed of lig-- oops not serious. Anyway, What if there is an equivalent to moving on the negative scale? Like 1, -1). It took humans longer to resort to using negative numbers then positive. Might this be the same?

Einstein's theory states that traveling at lightspeed is impossible. It says that the greater a mass is, the more energy or something needed. Meh actualyl I cant remember exactly...

Well is time moving forward constantly? What I don't understand is that even if as you go near the speed of light time slows down, but does it ever go backwards? Even if time is going extremely slow, it's still going forward

I hope you guys keep an open mind about this subject and not follow Einsteins theories like they are universal laws.Remember they are just theories they can still be proven wrong

light doesnt even reach the "speed of light" persay becuase the real speed of light would be in a vacum.


It's the speed limit becuase to propell anyhitng that fast you would have to have an unlimited supply of energy but the unirverse is not limitless and therefore you cannot travel that fast. the only way this would be possible is if we somehow broke the first law of thermodynamics : energy cannot be created or destroyed but can only change forms.

To have an infinite amount of energy, you'd also have to have an infinite amount of mass in order to obtain the erngy. The faster you go, the more energy you need exponentially. Therefore it would be impossible to reach the speed of light. As for the negative idea, I suppose it you could change the effects of inertia in a given space to allow rtavelling with very little egergy and then breaking it down into some kind of negative inertia? I don't see how that would be possible though, inertia is a property that we haven't been able to change at all

Yes, but right now most of time and relativity sciences are based on Einstein's theories. Also, a theory is a scientific hypothesis that has withstood the test of time and opposition, one step below a law.

Time is an abstract concept when you think about it, but I would term it a measurement measuring change. You can't have a piece of wood negative fiver meters long as it just has a positive measurement the other way, just as going backwards still has a positive measurement of time.

can we really ahve negative anything?

Yea, they could be wrong, but so far I do not recall any of his big theories ever being disproved...

Damn it's a wonder... how the hell does this guy come up with all these crazy equations and stuff in a time in which none of his stuff could be proved.

Precisely, unless you think of the anti-matter theories with opposites, or you use charge cancelling tiself out, you can't have negative anything. Why should time be able to be negative if all it is is a measuremnet of change or order to disorder.

even if charges cancel eachother out you still only have nuetrul and not negative.

Well I think negative is just a term we apply to things right? Negative as in opposite?

Well you have negative numbers, imaginary numbers, grassmann numbers, all kinds of mathematical concepts dealing with negatives that affect the real world. I guess that allows you to theorize some form of changing something into negatives by describing it mathematically, but I don't have a good example of something like that.

Yea but... Think about it... There is nothing negative. Its just not there!

Then what is a negative charge? We label it as negative, therefore it is an example of negative. Unless it's not truely negative.

Though I think negative in mathematics isn't visible to us at least, it must be there in some form, because don't we use it to explain physics and all?

Guess that's decided.

On a related topic, what do you think about teleportation? E.g., Arbiter's Recall.

I laughed when you said arbiter's recall.


I dont know, all of those sci-fi movies always have the theory of "disassembling atoms and reassembling them in a diferent Place," but is that really possible?

I doubt, I highly doubt it. You'd have to record everything at the subatmoic level in order to retain memory and exact cell order and have it reconstructed and make the body work again as if it hadn't happened. You're also effectively vaporizing and killing the person yuo transport, then make an exact copy or replica somewhere else.

Unless you can somehow keep the actual atoms that make up the person and move them...

I would compare it more to severing your arm then reattching it through surgery
