Is time travel possible? Discuss.

[djonkoman]

that cold infusion method sounds really interesting and convenient, have to try it someday. don't make edibes often tough, make them more for my friends than myself, I've discovered I prefer combusting my abv over cooking with it(because it takes a lot more with edibles to feel it, and because I can only get high from edibles when consuming them together with friends, so edibles occupy a very small niche)

 

[jeffp]

Everyone's different. I have a friend who claims that edibles hardly affect him while everyone around him is seeing God in colors. I feel that if you try your next round of edibles exactly the way I described you might be more impressed with it and perhaps not inclined to smoke the ABV. But give the leeching five days, not four. I think five is perfect.

 

[djonkoman]

well I've certainly been very high off edibles, but I do need at least twice as much as my friends. first time I made edibles were brownies, some friends only needed a few bites(were firsttimers tough, but back then I didn't smoke that often either), eventually I finished everything that remained together with a friend who then went upstairs, got munchies and passed out(was in a bus)(that time I had a very good high btw, just when we stopped to eat and I took a first bite from a hamburger it kicked in)(must've beeen my best busride ever, just barely remember the last part and still don't know of I just fell asleep a lot of times or that my memory was that bad)
somewhere last year I think I made chocolate with ABV(just 1/3 cannabutter+ 2/3melted chocolate and pour into a barshape), all my friends were high in the sky after half a bar, while after half a br I was just about at the point where I might feel something but wasn't sure yet if I really felt something or not.
and I've also tried consuming them while alone, baked a cake with a friend, each took half home. ate a quarter right away, didn't feel anything. few days later I split the remaining quarter with a friend(on liberation day), and we were both really high. that's when I first discovered I have to eat edibles with friends, tried a few more times but every time the same.
so now I sometimes make edibles for birthdays, even have some friends that never smoked or vaped weed and rarely drink(and if they drink it's mostly beerenburg-coke or some other mixdrink), who sometimes before a birtday start asking me if I will bring edibles

so under the right circumstances I can be very impressed with edibles, but it's just suitable for some ocassions, and takes more preparationwork etc. so always have a big abv-buildup, and turns out it works pretty well in joints, taste is gone and it makes me sleep a little longer, but not bad at all(I use a bit lighter abv for that tough)

oh btw, another problem I often have with edibles, there's usually a point where it becomes hard to stuff more done my troath, don't know why, I don't really notice any weedtaste or so, but after eating a certain amount of edibles it just won't go down smoothly anymore and I have to really force myself to swallow it, but unfortunatly the amount I need to ingest for a good high is past this point. (with those chocolatebars it was at around 3/4 bar I think, but can't remember ever getting to a noticable high with those so I just gave most away and sold some)

 

[jeffp]

I don't know man, I'm not crazy about the taste of "firecrackers" but I've been able to down them and I've considered mashing them up with chocolate ice cream next time around as an experiment, but brownies are very edible and the slight herb taste is not off putting to me. Someone here suggested adding creme de menthe chips in the brownie mix to completely mask the taste.

It's a different high, I think it's much more powerful. I usually add some fresh bud to the mix as well so there's more of an abundance of THC. Personally I wouldn't smoke the ABV but I'm aware that some people do. I dislike smoking weed but once in a while I'll take a hit if it's offered and it's sometimes nice to get that full blast instant effect. Steering the conversation back on topic, on rare occasions I'll smoke salvia and while I would never recommend it because it's extremely intense, it does render the notion of time travel as limited as it is very linear as a concept.

 

[djonkoman]

well the weird thing is that I don't taste any weedtaste, and the edibes are great at first but there's always a point where ity becomes hard, usually I swallow by just pushing my food to the back, not actively swallowing but using the swallowreflex, and after that point I have to actively swallow to get it down and aslo that becomes harder. I have no idea why it is, since before that point it's like eating regular brownies/cookies, and I don't smell or taste the weed in edibles at all even if others do. it also isn't related top feeling full, can eat more regular food and still happens on an empty stomach.
with the chocolate I also once melted it, made some toast and used the melted weedchocolate as dip. but didn't help either

I've never tried salvia(had the oppurtunity once, but was at the end of the night at a party and was already stoned and slightly drunk, so not the right oppurtunity), but on shrooms time felt nonexistant, like past, present and future were one, all happening right now

 

[stickstones]

just checked in here...are we talking about time travel?

Err... that and the negative dialectics of brownie play.

 

[djonkoman]

if you travel back in time a bit we're talking about timetravel

 

[stonedwarman]

I have given it some thought and I think that the only way to time travel is to somehow first travel to a dimension without time (unbound by time with no beginning and no end). From this dimension you can observe the flow of time in our universe in its totality. In this dimension there is no beginning, middle, or end because these are concepts that apply only in a dimension bound by time. From this dimension, you can find the exact moment in time you wish to travel to and then you can make the necessary hole between dimensions and travel there.

 

[Papa Woody]

Thanks for bringing us back on topic. I'd like to hear from some of the great minds we have on
FC, if the physical act of time travel is possible in both directions, how do you overcome the problem of traveling from your current location, this specific point of space that we occupy when we leave the current time, to land at your destination accurately depending on where the Earth was or will be at that time? While we can calculate where the Earth's location would be, how do you travel to that spot while traveling through time? Seems to me that you would pop up in open space at the new time. (and, in this fantasy, you only own a time machine, you can't afford a space ship)

 

[Frederick McGuire]

Well, my understanding is that time and space are essentially the same thing, a sort of fabric that is woven through the universe.
Without space, no time, without time, no space.

So I would think, If you had a time machine that didn't rely on speed, and was stuck to a fixed point on earth, that space would rewind with time. So you would stay where you were.

As for calculating our specific point in space, I would think it would be an absolute pain is the ass...
You would need to account for so many things...
Earth spinning on its own axis,
Earth rotating around the sun,
Sun Rotating around the SMBH at the centre of the galaxy,
The mily way rotating around a central point with andromeda, the andromeda-way system rotating around with the other galaxies in our local cluster, and so on...

Space is big... Real big...
And we are hurtling through it pretty damn quickly...
(of course, all that depends on your frame of reference...)

EDIT:
Here's one for you:
As light travels at the speed of light, it doesn't experience time.
So a star billions of light years away can emit a photon, it can spend billions of years traveling through space before it hits your eyes, but for the photon, it's whole existence was just:
Go, Splat.

 

[Papa Woody]

^^ Frederick, Yes, go fast and be absorbed by your retina along with the many photons along that axis from the star to your eye that will follow that first photon and suffer the same fate. Poor little photons. Spend your entire flash of existence from origin to stimulating my eye. Since time stands still at light speed, to us the photon spent x number of light years to get here, but to that little bundle of energy, it was just created.

I like your answer to my question. I don't know if I would want to be the first to find out which concept is correct.

 

[TwztedVaper]

I doubt this makes any sense at all, but..

Imagine this reel of camera film constantly moving in front of you, with each frame showing the event that happened in the last second or something (choose your favourite arbitary period of time).. so if you look at the beginning of the reel, it keeps growing and a new frame is added in real time every second as an event happens. Nothing exists to the right of the reel coz those events haven't happened yet, so technically the end of the reel where a new frame keeps appearing is the "absolute present".

Now imagine you're a little man running alongside this "reel of life", so you're basically travelling through time. now if you somehow manage to run as fast as the "speed of time", which is basically how fast a new frame is added to the reel, you will be stuck at the exact beginning of the reel. you won't be able to move ahead coz that event simply hasn't happened yet. so you'll be frozen in time, in a way, and be living in the "absolute present", which is what we have generally assumed humans are doing so far.

Now, however, suppose we don't assume that humans are in the "absolute present". What if the human speed of "processing" this reel of life was not as fast as 1 frame/second. What if we moved only at 0.5 frames/sec? That would mean we were living exactly halfway in this "reel of life", and would actually be living in the "absolute past", so to speak, and would actually always be time travelling in the regular sense of the world, just not the way we thought it would be since we assumed we were always in the present. Hence we'd be halfway through the reel, with plenty of frames of life available in front of us to time travel to. The illustration below with the blue stick figure better explains this, I hope, since you can see that humans would actually be in the "absolute past" of the reel, while assuming we were living in the present.

This model hence says that travelling into the future is impossible i.e moving at a speed faster than 1 frame/second, since there would be absolutely no "reel of life" frames available to process then. However, in our current notion, this "absolute present" is actually the future, since we are living in the past. Hence technically travelling into the future would be impossible, but in the sense of our human idea of time travelling, it would be possible, and there could be a wide interval of speeds at which you could travel at and move through the reel, forwards and backwards:

If you want to travel to the "future": 0.5 < x < 1 frame/second
If you want to travel to the "past": 0 < x < 0.5


So moral of the story is: we have always been travelling through time, just not at the speed we wanted
p.s imagine the possibility of having multiple reels. if somehow we could move through them we would be transcending our current life.

 

[Frederick McGuire]

It makes sense, but doesnt sound right to me.
Time isn't its own entity being created at a set rate, it's essentially a byproduct of space, and it's rate of passage is modulated by gravity and speed.

 

[t-dub]

Yes, its relative to the observer, excellent point. Time is more elastic . . .

 

[drumwizard]

I heard about this on the news and thought I would share...anxious to see what doors this might open. It kind of reminds me of Star Trek: First Contact when they discovered warp drive. There are hidden portals in Earth's magnetic field which directly lead to the Sun's atmosphere about 93 million miles away...

[Frederick McGuire]

That sounds cool, but the way I read it, those portals are portals in the same way a tunnel entrance is a portal...
Cool, but I don't expect it to lead to a warp drive any time soon

Haha I agree but I think it's an amazing discovery. Even if we could harness the power of energy or light, who would want to be transported to the Sun where they'll immediately be killed?

 

[t-dub]

Here is one Einstein came up with and it is proven mathematically and by experiment: We are all moving through space-time at the speed of light. Just as a car can travel both north and east on a map simultaneously, northeast, you are also moving through 3D space and time at velocities as well. The SUM of these velocities is always C or the speed of light.

You can tell this is true because we know the closer you approach the speed of light the more time slows down. So no matter how local or relative your experience is, we are all blasting through space-time together at the same rate, even though it doesn't seem like it, since events at different points in time appear to be non-local, and time and what we observe can be so relative to the observer.

Things are not as they seem

 

[Frederick McGuire]

And a continuation of that thought experiment,
As your speed through space goes up, the rate time passes will slow down, so as to keep the sum total the same.
Since your subjective experience of time doesn't change, the net effect is that everyone else would seem to "speed up".

The upshot of this: travel fast enough, and you will end up in the future.

BOOM. Time travel bitches

I love this stuff

Right me too! Forward isn't the problem (assuming we can somehow approach relativistic speeds with safety and energy economy), its back in time thats the "problem". . .

Edit: Regarding "Energy Economy" it turns out, IIRC, that as you approach relativistic speeds your mass increases towards infinity. You can never actually reach the speed of light because time would stop and your mass would be infinite and you would be consuming an infinite amount of power) This means that for all practice purposes you can't go that fast until you can harness a lot (and I mean a lot) of power in a very small space.
