Time is Relative - The Twin Baby Experiment

According to the theory of relativity, time dilation is a difference in the elapsed time measured by two observers, either due to a velocity difference relative to each other, or by being differently situated relative to a gravitational field. As a result of the nature of spacetime, a clock that is moving relative to an observer will be measured to tick slower than a clock that is at rest in the observer's own frame of reference. A clock that is under the influence of a stronger gravitational field than an observer's will also be measured to tick slower than the observer's own clock.

Such time dilation has been repeatedly demonstrated, for instance by small disparities in a pair of atomic clocks after one of them is sent on a space trip, or by clocks on the Space Shuttle running slightly slower than reference clocks on Earth, or clocks on GPS and Galileo satellites running slightly faster. Time dilation has also been the subject of science fiction works, as it technically provides the means for forward time travel.
Correction: Einstein published the his theory of Special Relativity in 1905, not 1919. Sorry about that!

Even if our time was slowing down, we wouldn’t know. It’s relative. As you approach close to the speed of light, space actually adjusts to keep the speed of light constant.

We are all under time. No one is above of it. Time is absolute. No matter how fast your speed is even it's the speed of light, , still time is constant. The only difference between a fast person and a slow person is their accomplishments.

This reminds me of the movie "Interstellar" :)

This is such a mis-interpretation of special relativity. Special relativity says that the time intervals are different in different inertial systems, but in no way expanding universe makes our time "slow down". Slow down relative to what?!

Einstine: Time is Relative

Me: Time is gold

Just imagine if the baby in the rocket ship had a TV on board that transmitted the news from earth. It would seem like 80 years of news happened in 1 day! Also, just want to make a correction: Einstein published his theory of Special Relativity in 1905, not 1919. Sorry about that!

Does anyone notice that Einstein blinks at 1:24?

[therebel]

That would explain why time at work is at a stand still

"We must see that the clock is working as normal although when we move away from the clock at the speed of light."


Elbart Einstine said if we go away from a clock( clock tower) at the speed of light, we will see the clock is freezed.
But If the speed of light is constant and non relative.
So
When we go away from a clock at the speed of light, we can't see that light coming from clock is stopped because the speed of light doesn't depend on our speed ( speed of light is not relative). So even when we go at the speed of light. We must see the light of the clock tower going at the speed of light.
So how do we observe that the clock of the tower is freezed.
I don't think it is freezed.


"We must see that the clock is working as normal although when we move away from the clock at the speed of light."


Right?

Man, your videos are so witty. The best discussions ( and videos) are the ones who sent you to read and learn more about a subject. This is exactly what I'll do after writing this comment.
Awesome job!

[TheLifeFormulaa]

Interesting take. Especially since everything feels a lot more fast paced

Fascinating ! One day, we will be able to "use" this phenomenon, like the way we use mobile phone today. (a couple of decades back, mobile phone seemed as exotic as time dilation)

[turbonbc]

We are speeding up thus time appears to be slowing down. Vibrating faster. If you think about it, the faster something vibrates, the more trips it takes from point A to point B thus more experience/wisdom/knowledge ect... can be gained in the same amount of time.

[realcygnus]

Interesting idea ! Just as with GPS, where the Total combined effect = SR+GR = -7us/daySR + 45us/dayGR = 38us/day) both GR & Special Relativity effects are/will be at play(in opposite directions & at various magnitudes/ratios). The further away a distant galaxy is, the faster it is "receding"(SR) but also the less gravitational field(GR) there will be for any "local object" to interact with, as the density of the observable universe thins out in the far future, due to this accelerated expansion. Anyone know of charts/graphs/predicted numerical calculations of these specific overall combined long term cosmological effects ? btw it is thought that our "internal sense" of time is NOT affected by such effects.(plz excuse if I crossed e/a's).

Time is relative to a frame of reference.

Our closest clock, if you will, is the sun.

If let's suppose someone traveled to Andromeda.

And let's suppose a baby and mama traveled on a remarkable spaceship. They can survive, eat, and so forth. Even the feature of gravity much enough as you might have on earth. Or for the sake of travel, maybe gravity is suspended in let's say the speed of light.

Since we're also able to determine the distance of Andromeda (distance is a frame of reference), then there is a definite path of route to go. And therefore a destination.

If let's say mama and baby are traveling at the speed of light and reach their destination in whatever time interval that will be, their biological development will also occur. This however is a mystery. Since we're not able to see how that would be. Though, if the spacecraft has adequate light, air, and other environmental conditions for thr mama and baby's health, they may grow in a relatively young state than on earth, given the conditions. How that will be and what they will look like? I don't know.

But let's suppose their biology develops reasonably better than on earth. Possibly not what we would call the advanced signs of degeneration.

Let's imagine mama and baby go for a celestial vacation. And from the time that they left, went on their getaway, and came back, over an interval of 50 years as would be on earth.

Her baby, let's suppose a boy, only shows advancement of aging much like someone who looks 20 years old. And the mama looks 30.

The Father, and suppose their other child stayed behind, will appear as one might expect them to age.

Perhaps the mama was in her late twenties when she left. And the baby was a year old.

The Father might had been in his late twenties when she left. And the child who stayed behind was 10.

Upon return, the man is in his seventies, but his wife appears in her thirties. Though, her age on point and reference of time on earth places her in the seventies. Her baby's biology had no serious degenerative effects whilst on the space voyage. And so the Son is more by biological comparison on earth, like someone in their twenties. But his sibling is biologically as one would expect in their sixties. And, the returning son's age by earth reference of time is in his fifties.

The real question: what are the best effects on biology in space and conditions far less degenerative than on earth?

[gargoyled_drake]

The satelite thing might as well just be an example of math not being precise at all. And yet again we must invent new rules to our math to make it seem flawless.

[robertlong]

Thanks to photons. They carry information and apply the effects of time in a sense. It also depends on the amount of matter present as well as how many interactions are going on that add or remove things for photons to interact with. The scary part is. Thanks to the speed of our solar system. It has created a pocket in spacetime. So it becomes a solar system time constant. And each planet and moon ages differently thanks to mass creating gravity that also messed with photons. So outside of our solar system. A whole different solar system. It is aging differently than compared to our solar system. Some solar systems have aged a second or less while I typed this. And some solar systems a day or more has passed for example. It's all pretty amazing. I love to study this stuff. But I am more into the information theory. Spacetime is great but it needs some updating.

[JohnW]

you sir, just blew my mind... I never even tried to make a correlation between evolution and expansion... truly thought provoking, I been sitting here thinking about that idea for over 30 minutes.

[astronomical]

So, if traveling at 186, 000 miles per sec (light speed) freezes time, then, why does light from the sun take 8 seconds to reach earth?

Please let me know soon
