Time Dilation

[Panmisiek]

I dont get it at all.

According to Einstein Theory, if human could travel with a speed of light, it could as well travel into the future (but not quite the future like entering through portal but more like travelling as a result of time dilation)

Time dilation was mentioned in Planet of the Apes and in Interstellar if someone watched.

I say that I have to disagree with Einstein statement. I think regardless where you measure the time, earth, spaceship or whatever, the time will run the same way not faster or slower. You may travel quicker, but its still the same time.

If someone got better understanding or own theory, please feel free to share it.

You have multiple experiments proving time dilation. GPS systems use it. You can look up a pretty simple thought experiment that derives the time dilation equation. The most complex math needed is Pythagorus's theorem.

Edit: Here is a link to the thought experiment.

I have to borrow this comment:

We shouldn't think of time as a "thing" moving in a "direction". We may consciously perceive time as moving forward but time actually doesn't exist. Its neither matter nor energy and nothing, not even gravity or velocity have any effect on it. Time is just a tool we invented to calculate speeds, locations in space and schedule events. Time can't be distorted, slowed down or speed up. You can't age slower or faster or travel to the future or the past. You can't experience years while someone else only experienced one hour at the same time. To say speed or gravity has an effect on time is just as idiotic as saying heat or electricity has an effect on distance. You have to be conscious to perceive one moment to the next. Time outside of consciousness does not exist! Time is kind of like distance. It may vary as you walk forwards from point A to B, but "distance" itself does not really exist. It's not a force which anything can interact with.

So you telling me that if you board a spaceship who can travel with a speed of light, you will experience a day of events while me staying on earth will experience a year worth of events in the same time?

How stupid that sounds?

There are many in physics that are very counter intuitive. We follow the math. The problem is the math leads us to make predictions, these predictions are then tested and proven. We can't dismiss things that are counter intuitive because we use these concepts constantly in modern technology.

The only thing that is constant in time is that the effect must happen after the cause.

Ok let me ask you differently.

We have 2 clocks, whatever clocks, Casio, Rolex, both same brand, both synchronized at the same time, 10 AM. One is placed on earth and 2nd in super space ship who travel with a speed of light. After 1 hour on earth, the clock shows 11:00.

And here a question to you, what time clock will show upon arrival after 1 'earth' hour speed of light travel?

According to the theory, it should be slower, but then events in a spaceship would have to be slower as well?

You get it?

Your hypothetical has a problem in that you can't travel the speed of light. It would require an infinite amount of energy to get anything with mass to the speed of light. To be honest, I'm not entirely understanding your question.

The time dilation equation is very simple. t'=t/sqrt(1-(v/c)^2)

v is the relative velocity. If v = 0, t = t'.

Y'all foolios need to watch Interstellar.

Basically, the heavier something is, the slower time moves. That's why fat folk are so slow.

 

[faustian]

Lol @ TS sitting around reading about this shit and deciding "hmm well I disagree"

 

[MoparOrNoCar]

Yep time went hella slow on that water planet with the big ass wave on Interstellar.

Does that answer your question TS?

It doesn't matter if you can travel or not. We just assuming its possible just to derail Einstein theory.

You know whats the difference between my hmm well I disagree and random that says hmm well I disagree?

I am backing up what I am saying. Explaining people how I see it.

If it makes you feel better, Einstein was at least somewhat wrong. Quantum mechanics and relativity are incompatible theories. However, there are plenty of experiments that prove time dilation. Every time you use a GPS, you prove time dilation.

 

[NoGoodNamesLeft]

you came to the right place TS, Mayberry is world renouned for their amount of experts on everything from quantum theory all the way down to groundhogs. a more learned group does not exist, you lucked out.

stopped reading here,

sherdog in a fucking nutshell

You do know that time dilation has been measured, right?

As far as disagreeing with Einstein... it's a free country, but that's being an idiot.

If it makes you feel better, Einstein was at least somewhat wrong. Quantum mechanics and relativity are incompatible theories. However, there are plenty of experiments that prove time dilation. Every time you use a GPS, you prove time dilation.

General relativity and QM are currently incompatible.

The theory referred to in this thread, special relativity, is compatible. There is Quantum Field Theory.

Call it will you will, but things change and evolve. Entropy increases naturally. In order to quantify this we need something we call time. Sure we called it time, but it's a natural entity.

An apple existed before we called it an apple.
