Is time travel Impossible Because time Doesn't Exist?

[Anomalocaris]

Don't know where to put this is i'll try here...

Time is an interesting subject, although i think we have forgotten time is man made. The only reason we have "days" day and night, is that the earth orbits the sun.

Technically, i no the Sun does not orbit Earth, the Sun and all the planets are orbiting around the center of mass of the solar system.

But you get my point, seconds, minuets, hours, days, where created by man for our very own convenience and everyday lives, but in actual fact we are in only one constant that is now. No tomorrow no yesterday only the ever expansion of the universe.

So how does that define us? i guess the statement "you are old as old as you feel hold some weight"

I look at time as tool for measuring, time was invented by man as a means of measurement and nothing more. When did time gain magical powers?.

Time is a very handy tool, but people have to remember, MATH IS NOT REALITY!. Math is a tool like a mile or liter etc. Time is in the same category as all other measurements, they don’t exert a force on the physical world.

so with this being said, does this make time travel impossible? as i see lately the idea seems to be gaining traction.

i am not inserting a truth claim here, this is just my personal opinion, i just want to see what people think....

I assume you mean travel backwards? Traveling forwards you can not help but do.

I think you need to define time more precisely before it is even meaningful to begin to explore whether what you define as time can be made to behave in such a way that you would perceive it as running backwards.

"We are moving through time all the time, it is not impossible. "

but the time we are moving though is now, like you have reached the end but the end is constant if you no what i mean? :B thats what i think anyway, you can't move forward into time that hasn't happened yet.

Let's say you are swimming in an ocean, let's call wherever you are on the ocean "your-current-location-point", now if you swim forward, your new location then will be "your-current-location-point", so did you move forward?

Yes but the constent end i was refering to (the now) is i traveling with you, you move foalwars but consten end moves to


I need to understand this constant end i'm talking about more, its hard to explain, its like what you say the word "Now" by the time you have said it, its not now anymore, but a new now, Ahhh i dunno lol.... not just the word Now, any word.

Also i'm not sure how relevant moving falward in person is in relation to the the expansion of the universe.

It's not just the word, it's about having a frame of reference. With the ocean example, if all you see is still water all around you, you won't know where or how far you have moved. But if there was a chopper flying above looking at you, they can see your position change. Similarly, whatever you consider future or the past are points within the time stream(for lack of a better word), you need an outside or constant frame of reference to determine the changes.

I think time is the constant NOW that is the ever expansion of the universe, one point, i dont think you can go back, as, is there really a past to go back to?

You can judge the future on our actions we remember now, its in out minds not the past, i understand things grow and get old, but it think it's all happening at this one constant point, our memories created the past, and out thoughts create the future.

We already see the experience of time is not a universal thing even outside the subjectivity of human perception.  Each point in the universe sees the behavior of each other point as if time at the other points progresses differently, according the relative speed, influence of gravity, of the two points.
What law of physics directly prevents any event in the universe from being perceived to happen backwards from another point?  Such that from the observer's point, the formation of memory occurs before the event at the point being observed?

If that were to happen, wouldn't that be the same as the observer's point traveling backwards in the time of the observed?

I have nothing to add to this convo. I came here just browsing then I too wanted to hear from Alex and saw he liked a post so I figured if I finished the thread I would get to it. No, no I didn't. Alex you have disappointed me :p

Time is what keeps everything from happening all at once.

Hm? Time was not invented by man. Time exists so long as matter exists. Things get older.

Especially my knees, dear.  I think they are aging faster than the rest of me.
