Is time travel Impossible Because time Doesn't Exist?

[Brian37]

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....

"Time" is not man made, only the word is. Language is what we use to describe our observations. Time most certainly is real.

1 is an abstract word but can be applied to what we observe.

1 apple

1 car

1 day.

Time is relative is what you should focus on, not that it exists, time most certainly does exist. If time didn't exist there would be no scientific measurements and you wouldn't even be typing your post on this computer. 

Mercury has a different solar year than earth. But even our own sun has a galactic year because it too revolves around the center of the galaxy.

Instead of being wooish or dreamy eyed bone up on real science. Time can be a really freaky thing to ponder relative to QM and the sub atomic world. 

It is an illusion in the sense of point of view, but it is most certainly a very real measurement pragmatic to understanding science.

Change exists, time does not.

But SpaceTime rolls off the tongue nicer than ChangeTime!

I think time is like gravity. We know and can measure it's effects only, not time itself as a discreet entity in itself. Like Gravity.
Is there such a thing as the theory of time? Do we need it? Why do we need the theory of gravity?

I'm going to wait for Alex to reply, then bogart his answer.

Was just going to type "someone call Alex"

I look at this way, going "forward" in time is merely change happening, going from a higher order energy state to a lower order energy state; increasing entropy.

Excuse my ignorance but you have completely lost me.

[Little lunch]

Nope, I think we got this one covered.
Even superman needs a break from time to time.

Hey Budsa 11, I just looked up Boards of Canada and they're pretty good. Thanks. :-)

Yes like i said i agree with this

when i say time its man made, im refering to the word that describes the mechanism.

Sorry i'm having trouble quoting for some reason just a bit of noob problems

I may be a bit pedantic on my part. But the problem with laypeople, especially theist, they have a horrible tendency to twist what scientists say to suit their agenda. That is why I find it important to make clarifications.

For example, if you have not run into this bullshit, believe me you will.

"Theory" to scientists is based on repeated experiment, testing and falsification and peer review. So the "theory of evolution" is FACT.

But to the theist, what those idiots hear is, "Oh it is just a mere guess".

Theist pull the same shit misquoting or lying about what famous scientists say, like Einstein when he used the word "God" and all he meant by that use was metaphor in how natural science is used to describe the laws of nature and the universe, not an old bronze age comic book character.

It wasn't that you did anything wrong. It was merely a lip twitch on my part because of my fear laypeople will bastardize what you say twisting it or taking it out of context.

Just be aware especially with hard core theists that how you use words and scientists use words are not how they see the same words.

Little luck! yeah, Boards Of Canada are very good, i have made 3 tribute mixes, if you are interested part 1 here https://www.youtube.com/watch?v=xw5N6k7XJZM

ohh yes, i have run into this problem already, perticulaly the evolution is just theory bullshit, when they are ignorant to what a scientific theory actually is.

"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?
