Time travel??? Mainstream science guys invited:)

[grzegorzsz830402]

Time travel???

Is it possible?

First, as far as theory goes, what is possible?

Second, as far as reality goes, what is actually within our reach?


It is possible to hit lottery jackpot 100 times in a raw, in theory.

Will it ever happen?
No.


If you tackle this question from mainstream scientific model perspective, there is no need to state assumptions as they are well known.

If there is something, that there is no scientific consensus for, please state what you lean towards more.

If you tackle this question from other perspective, your own set of assumptions (model), please state relevant differences
from mainstream scientific model.


For purpose of this exercise I wont challenge any assumptions, I may challenge logical consistency within any assumption set.

So for mainstream scientific model, I accept assumptions like time being a dimension etc.

It would be nice if anyone who wish to challenge someone's idea, would do the same.

You can not challenge assumptions set they have chosen, you can internal consistency of proposed ideas, within this assumption set.

Time travel???

Is it possible?

Ask any time traveler. Oh wait, there aren't any. Time travel is fantasy.

Can you state, is it your perspective as your personal set of assumptions goes?

Or, are you addressing this from mainstream scientific point of view?

As Far as Theory Goes, What Is Possible?

In theoretical physics, time travel is permitted under certain conditions within the framework of Einstein’s general relativity and other speculative models. Here are the key theoretical possibilities:

Forward Time Travel (Relativistic Time Dilation):

General relativity predicts that time passes more slowly in stronger gravitational fields or at higher velocities relative to an observer. This is known as time dilation.

For example, an astronaut traveling near the speed of light or orbiting a massive object like a black hole would age more slowly compared to someone on Earth. This is effectively forward time travel, as the traveler could return to Earth to find a future date while having aged less.

This is not science fiction—it’s a well-verified phenomenon. Experiments with atomic clocks on fast-moving airplanes or satellites (e.g., GPS systems) confirm time dilation, though the effects are minuscule in everyday scenarios.

Theoretical Verdict: Forward time travel is well-established and non-controversial within general relativity. Backward time travel is mathematically possible in specific scenarios (CTCs, wormholes) but relies on unproven physics and faces significant theoretical hurdles, such as stability and paradox resolution.

As Far as Reality Goes, What Is Actually Within Our Reach?

Forward Time Travel (Practical):

Forward time travel via time dilation is not only theoretically sound but has been experimentally verified.

For example:
Muons (subatomic particles) traveling near the speed of light decay more slowly than expected, effectively “time traveling” into the future relative to Earth’s frame.

Atomic clocks on fast-moving objects (e.g., airplanes, satellites) tick slightly slower, as predicted by relativity.

Realistic Reach: With current or near-future technology, forward time travel is possible but limited to tiny time differences (e.g., microseconds for astronauts on the International Space Station). Significant jumps (years or centuries) are theoretically feasible but technologically out of reach for now.

Ask any time traveler. Oh wait, there aren't any. Time travel is fantasy.

I would render it theoretically and practically impossible within my preferable assumptions set.

Material Absolute Objective Reality.

I would say it is possible, from General Relativity perspective.

Of course, I know that and if you did too, why ask the question?

Are you telling me that your question does not imply the creation of a time machine to travel to any time, past or future?

If it does, then it's fantasy.

 

[grzegorzsz830402]

So, no. My question was totally not about what you have assumed.

I was interested, how many different perspectives there will be, from mainstream scientific point of view.


How many from personal points of view.

And can people respect what I have politely asked for.

Which you have obviously not.

 

[(Q)]

How many from personal points of view.

Sure, personally, everyone wants a time machine, its on my Xmas list.

This is internally inconsistent.

It can not be on your Xmas list, as you consider time travel is fantasy.

I do not challenge your assumptions set, as I promised, only internal consistency of your ideas.

Путешествие во времени невозможно. По крайней мере, в вашем физическом теле, оно невозможно. Объясняю почему: ваше тело состоит из частиц. Эти частицы уже существовали в прошлом, только в других состояниях. Они не могут находиться одновременно и в прошлом, и в настоящем. Это нарушило бы причинность, и закон сохранения. В будущее вы тоже не можете попасть, по этой же причине. И есть ещё одна, которую я вам пока не буду говорить. Вам сначала с материей нужно разобраться, а потом уже переходить к более сложным вещам.

 

[(Q)]

It can not be on your Xmas list, as you consider time travel is fantasy.

Santa knows its on my list, so I expect him to deliver. I mean, if Santa can't deliver me a time machine, then who can?

 

[grzegorzsz830402]

Internally inconsistent.

You can not expect from Santa to deliver you gift that do not exist.

Time travel???

Is it possible

To go forward and back again like in the movies. No

 

[grzegorzsz830402]

Time travel is impossible. At least in your physical body, it is impossible. I will explain why: your body is made up of particles.

I assume that you are replying from personal assumptions set perspective.

First, as far as theory goes, what is possible?

Second, as far as reality goes, what is actually within our reach?

Can you address above from your personal theory perspective?

 

[grzegorzsz830402]

To go forward and back again like in the movies. No

Interstellar is generally considered to be scientifically accurate, particularly in its depiction of physics related to black holes, wormholes, and time dilation. Kip Thorne, a leading expert on black holes and general relativity, served as the film's scientific consultant and executive producer.

Мартин, он её тебе на санях что ли принесёт?

 

[grzegorzsz830402]

Мартин, он её тебе на санях что ли принесёт?

(Q) Name is not Martin.

I think he have clarified this before.

I also think you remember this and keep calling him Martin because you do not like him much.

No, Santa can not give you things that do not exist.

У него в профиле написано: "энцефалоидный мартини". По крайней мере, так у меня переводится. И я понятия не имею, что это означает. В русском словаре : "мартини" - это алкогольный напиток. Ну не называть же мне его "алкоголем"? Лучше уж пусть будет "Мартин".

 

[grzegorzsz830402]

I think, you could conclude that it is not what I was asking about?

(Q) stands for Quasimodo

I'm traveling forward through time now. There's a lot of fellow travelers on this rock with me.
