is time travel possible?(not including twins paradox) (1 Viewer)

[blueduck]

would that prove God? as the controller preventing us from scewing up our histories?

hmmm could be a very convincing arguement... but like i and so many people said before, u can only move forward in time not back, so it is merely a thought experiment (much like god)... but very intriguing concept indeed......

btw i failed in finding info on jonathon hartnett's analysis problem no 18 ...if anyone is in need on some procrastination i challenge u

Should we STUDY something RELEVANT to the PHYSICS HSC COURSE?
Dude, that would be hilarious if we got a question on this XD

 

[untouchablecuz]

unless you hold a pantheistic conception of God

does that mean once you go forward in time you can't return back? so you cease to exist in that previous time frame?

 

[untouchablecuz]

whats the relevance of the euthyphro dilemma to this discussion?

yes as to time travel forwards in time what you are essentially doing is goin so fast that u experience time at a slower rate than everyone out side of your frame of reference so that when eventually u decide to slow down and go at the same speed as people out side of ur frame of ref they will say that more time has passed by... this is part of einstein's special theory of relativty... in reality u haven't really "time travelled" i.e. jumped to a different time frame as happens in back to the future....u have just experienced time at a slower rate

apologies for rambling... i did phys study this morin... damn knowledge really stuck in there good

 

[untouchablecuz]

just saying it in reference to the god debate

ah ok

whats your view?

 

[untouchablecuz]

haha

thats morality for you

 

[rorycole92]

If timetravel (into the past) is possible and our present is another dimension/universes past, then wouldn't the people from the "future" have traveled back to us already, as they would have achieved the time travel that we might one day achieve?
Just a thought....

 

[rorycole92]

Although travelling into the future is more likely.

yeah but for this to happen we'd need to be travelling at relativistic speeds, which means massive g forces, which means our bodies would explode, so unless humans evolve drastically in the future i don't see time travelling happening.

 

[untouchablecuz]

i once punched someone at relativistic speeds

didn't see my hand for weeks

g-forces occur when u are accelerating so if u employed a muti stage system over a long period of time with a hell of a lot of fuel then it is possble to reach the required speed but like sikhman said the point is that we dont have this technology yet

If we say the future is not yet determined, that it isnt a realm which already exists i.e. it is a realm of unrealised possibility. Then if we were to time travel to the past one must have already existed in the future which by this stance, he/she doesn't exist. Maybe if we took a view with a real and definite future? But then how can one exist both before and after one is born. Also then the issue of causal loops and the butterfly effect is raised. If some time travel machine was made then as it would begin to move back in time, it must surely collide with its forward travelling self. Then there's the quantam interpretations which i'll leave for another time

I once punched somebody... Now my hand is broken and my HSC is Fucked

i think you must've knocked out your brain too... havn't seen that in weeks

dont get the physics but yes very funny before u think about it .... >>>

yes yes very nice but if people wish to post stuff such as "what if we could travel back in time and then did this.... omg it would totally fuck everything up!"...please explain how one could travel back in time prior to eleborating on how it would mess stuff up

 

[emmatheron]

Think of it this way. If we could travel into the past or, if at some point in the future, we could travel into the past, then we would be encountering time travel tourists, wouldn't we?

u never know... how do some investors make all the right moves, spending their life savings on a dodgy company

 

[annabackwards]

^^ lol

I'm still very wary of this implication of fatalism tho...

As am I. I believe the universe conspiring to prevent you from being able to kill someone in the past is more plausible than being able travel back in time and kill because it'd just be too complicated XD
