SCI: Time Travel 101: A How To Guide

reply to post by Eitimzevinten


Yeah, but this is the explaination that gimme_some_truth gave, If you travel 99.99999 or whatever % of the speed of light away from earths orbit then came back, only a certain time would've passed for you, but a lot more would've passed for earth. Or so he says anyway.

Just wondering. Don't really know what to think yet

So the theory of relativity says. I just simplified it in an attempt to not only help myself further understand the theory but also to help everyone else who may be interested.

Anyway, you have that correct. According to the theory, time slows down for the person moving. The faster they move the more time slows for them. The people who are not traveling at that speed experience time as they always have. Time slowing down for the person moving does not push you forward into the future. It just slows down time for you while the rest of time is moving at a much faster pace. What you have then is a person who just travelled for 6 months (or what have you)m there time and because time has slowed for THEM only, they see that several years has gone by for everyone else.

You got it!

How would you solve paradoxes without going into another timeline?

Very simply ...... nature ABSOULTELY PROHIBITS time travel backwards in the same timeline !

So, disallow backwards time travel and you resolve ALL potential paradoxes.

Thanks. Now I would like to read a second opinion.

Have a read thru all the posts and you'll have much more than just a "second opinion"

Time doesn't slow down, their observation rate speeds up. All objects involved age the same amount of time but, to the observer inside, they will see things moving much slower. Time was made-up to meausre change. They see slower change if the human body attains the ability to interpret information at that speed upon reaching it however, their one second occurs more often then the lower speed 1 second.

For every 1 second "real" time, 5 seconds or so would pass for the faster observer again, only if their observation rate is adapted to the speed at which they are moving.

Einstein based all his time related findings on the speed of light and assumed that human observation would adapt to any speed they are moving so long as it did not exceed the speed of light (at which point, you "observe" faster than anything that can be seen at our level). The faster something moves, the relatively slower everything else is which could provide an illusion of less time passing however, I'll maintain that the time used for traveling ages everyone and thing the same.

While the observer may feel like less change has happened for them, the ship they are traveling in can be observed from the outside to have aged 3 years as well as everyone else. If the outside of the ship is observed to have aged 3 years in normal time, then the inside of the ship must have as well. If the inside of the ship has also aged 3 years normal time, then so has all its cargo.

If somehow one part of the ship or its cargo had less change happen to it compared to change that was observed that must have happened from the outside, physical particles must have slowed down somewhere along the line. The physical partices are being accelerated more (having more energy) than their outside companions so this hypothetical slow down seems illogical. Aside from having such a vehicle, we'll all have to just keep thinking about it, so at this point, no one really knows how it could all work.

Wow. I have to say. GREAT post. I really enjoyed reading it. Just two questions:

1. I'm curious where you've learned most of what you know. I love reading and learning, and books on the subject have always fascinated me.

2. Also, it reminds me a lot of what Stan Deyo gave a lecture on a while back, and he mentioned the relationship of UFO crafts and time. Do you have any thoughts on the subject? (Specifically how technology used to cancel gravity alters time.)

Thanks.

Hi, I have picked most of what I have learned up from a number of various places through out the years. Different books, legit scientific websites and even the occasional TV show. The inspiration and much of the research for this particular article came from a book called " How To Build A Time Machine" By Paul Davies.

2. Also, it reminds me a lot of what Stan Deyo gave a lecture on a while back, and he mentioned the relationship of UFO crafts and time. Do you have any thoughts on the subject? (Specifically how technology used to cancel gravity alters time.)

My take on UFO craft and time... Well from what I have learned, it does not matter whether the craft is of terrestrial or extra-terrestrial origin. If it is capable of accelerating away from Earth ( Or any other planet) at a high rate of speed time for the observer ( the person in the craft) will be affected in a way that it slows down for them.

As for technology used to cancel gravity altering time, admittedly I don't really know much about that. There were quite a few posts in this thread discussing theories that included that idea but if I recall they were pretty much crack pot theories that science has pretty much proven incorrect.

Besides, if you are in space travelling , gravity would not really be a factor anyway. That is, if I am understanding your question correctly. If not Feel free to slap me upside the head and reword it.

Peace and love

Ha, now THAT is the truth... Especially when it comes to ATS. On any given thread you will get more than just one opinion.

But by all means, get as many opinions as you like. Just make sure you ask people who know what they are talking about.

As I have pointed out before, most of my research was done from a small book called " How To Build A Time machine" By Paul Davies... It is a small book and it explains such a complicated theory in laymens terms... In fact, it was my inspiration for writing this article.

I always enjoy taking what I know and passing it along to others in a way that is interesting and easy to understand. That was my goal for this article and I would say I have succeded, after reading what everyone else has had to say.

I want to encourage everybody to not just take my word for it. It is never wise to just take anybodies word for it. Go out there, and do your own research, come to your own conclusions, make up your own mind.

To let simply take some ones word for it and let them make up your mind for you is to let them control you. So go out there, learn, research and most importantly, question everything!

From a physical science theoretical perspective, travel to the future is not possible because,

1) it does not yet exist,

2) according to string theory, by observing the future, you would change it to the observable string and not necessarily the expected string of contiguous outcome. Disjointed time, where random and instantaneous paradigms of massive change and upheaval are common occurrence. Like let's say, you go to bed as a Chef in Paris and wake up as a plumber in No-Where, Idaho. Bonjour Mssr. , ou a le biddet? Sacre Blu. Or you go go to church and its a bank. You go out for food and become food.

3) Since these tectonic shifts in spatial and temporal location do not occur in the present, they do not occur in our future, nor in our past, so logically, its copper plated conclusion that since there are no time travelers, there never was, and could never be. Otherwise they would already be here. I hope you understand the elemental logic of that fascinating argument.

But all is not lost. Travel behind the present is not in contra to any physical laws, that are specific to our current physical construct. I do think that visiting the past is within the realm of possibility, but highly improbable. By the time man throws off the tribal blinders the Sun will have dwarfed and the Earth will again be a dark chunk of rock floating in the periphery of the cosmos, so if there is a entity living on that rock on the outer fringes of the universe somewhere in the dark future of the planet, we call Earth, he should fire up his time machine and put a big Yellow Sticky Note on our collective fridge.

Inter-dimensional travel, l where you you could slide to a existence previously invisible to you and then warp time before returning to a existence known to you could be a way to visit the ancient past. Just remember that time does not exist. Clocks are mechanical devices that mimic the rotational characteristics of the earth and sun. Time is not a dimension. Its a device that busy folks use to keep every thing from happening all at a once. Peace Love Out.

Having read most of the posts, interesting as they are, I don't see any mention of the possibility of time travel via higher orders of dimensions (higher than the 3 - or 4 including time - that we experience daily. Google a flash video called "Imagining the 10th Dimension." It's is based on a book of the same title. It will blow your mind! That is, if you can understand it. I've watched it about 20 times and am only beginning to understand through about 6 dimensions.

Great post i love this kind of stuff.

I also wonder about the dangers of ones "soul" so to speak, would we leave the person we was behind if we travel back in time and yet havent even been born yet. We'd effectively become a vegetable and 100% likely drop dead the second we emerge from the wormhole. The same can be said for teleportation, unless we can find ways of storing entire thoughts/memories/body controls then humans are unlikely to go back in time unless we develop A.I. beings to do our work for us.

Got me thinking, we can only travel back as far as the day we were born.

Or maybe a new "soul" take your bodies place, same memories as you but a different person (freaky but cool)

Have you read 'The Elegant Universe' by Brian Greene?

Incredible expansion on what you're posting.

One of my favourite books!

Much love...

the more and more i think of wormholes, the more and more it doesnt make sence with time travel...i can understand the theory of a wormhole to shorten the distance b/w two locations in space...when a worm hole is open, in theory, the other end is lightyears from your current position...which will only take hrs to travel to the other end...wormholes are gateways to the a distant "present" location in space...how can wormholes allow us to travel back?...even if the universe is flat or a sphere, i see a wormhole as advantage to travel far in space in hrs...i dont think we will ever know...it could very well be wormholes send you to a "past" location in space...

I have read bits of it, but never the whole thing... Every time I picked it up life got in the way... Things are going slow right now, so I think I may go grab it off of my bookshelf.

Thanks!

Peace and love

wow!!

this was a great article man!!!
truly great!!

like,
it should be seen in more places than just ATS. lol

well done bro, well done!

looking forward to more!!

amazing! thank you!!

And just when I thought this thread had gone to that place where all threads eventually go ... someone comes along and breathes a bit of new life back into it ... which is great as this thread has a lot of good stuff in it from many posters and deserves to continue to delight, amaze and educate the ATS community

reply to post by tauristercus


It truly is a great thread.... Now I am not saying that because I authored it. I am saying that because of what everyone else has made of it!

There have been so many great, intelligent well thought out posts that have added so much to this thread. I can honestly say that this thread would not be what it is without you guys.

This thread is the perfect example of what ATS is about, intelligence, civility, decorum, and much more...

There has even been a spin off thread or two... Which is great, because we were able to inspire others to write yet another great thread!

Now I wonder, I have had a few books suggested to me. Most recently 'The Elegant Universe"...

I wonder if there are any other books regarding time travel, Physics and other such topics that have come up, that make a great read....

Anybody have any other suggestions?

Thank you. I am so happy that you enjoyed it. Now if you think that was great, you should really read the full thread. I mean, there have been so many great posts and expansions on what I discussed.

It is a very long thread, so one of these days get comfortable, and sit down and read it! There is so much wonderful info in this thread. So much to take in yet written in a way that it is possible to actually take it in...

When writing I try to take a subject that interests me and write it in a way that is understandable and enjoyable for everybody else...

This one was a challenge... I mean, we are talking about physics and time travel and the theory of relativity! So much complex stuff, yet if explained in the right way, so simple to understand.

You know, I have wanted to write text books before... The big problem with them is the writer does not know how to make it interesting for the reader... They report the facts but that is it... BORING!!!!

Write it correctly and even the least interested in the subject will enjoy it and learn. Learning does not have to be a chore... It can be fun... and I think this thread proves that...

Sorry to get off topic here. Just wanted to say that

Thanks for your support.
