Relativity

One thing as related to another.

Picture you standing at a train station.

Picture a train passing at 100 miles an hour, kilometers if you need.

There is a person on the train bouning a ball.

The person on the train platform sees the ball on the train moving up and down in an extended "W" wave. due to the trains motion.

The man on the train percieves the ball bouncing in a vertical plane.

If you know pythagoras (Triangles) you will understand that the balls movement has an x and a y dimension as viewed from the platform, therefore it has a hypotanuse. This is the distance travelled in time X.

If you are on the train, the ball only travelled in one plane which is less than the hypotanuse distance as seen on the platform, in teh same time X.

So relativly, the ball has travelled different distances as viewed from different locations.

This is the basis of time and distance/speed differences relative to different locations, and is the basis of the paradox.

Time is a man made invention that we use singularly, it is now 8.22.

However, in the greater scheme of things time is the fourth dimension. You have 3 physical dimension xyz and one time dimension to get 4 d. They can not be separated.

People go to say there are umpteen dimensions, but that is another chapter.

Try Stephen Hawkins A vbrief history of time.

Did you try wikipedia for a simple explanation!

The twin paradox, sometimes called the "clock paradox", stems from Paul Langevin's 1911 thought experiment in special relativity: one of two twin brothers undertakes a long space journey with a high-speed rocket at almost the speed of light, while the other twin remains on Earth. When the traveler returns to Earth, he is younger than the twin who stayed put. Or, as first stated by Albert Einstein (1911):

If we placed a living organism in a box ... one could arrange that the organism, after any arbitrary lengthy flight, could be returned to its original spot in a scarcely altered condition, while corresponding organisms which had remained in their original positions had already long since given way to new generations. For the moving organism the lengthy time of the journey was a mere instant, provided the motion took place with approximately the speed of light. (in Resnick and Halliday, 1992)


This appears to be a paradox if one expects that, according to relativity, either twin may validly claim to be "at rest", and thus each expects that the other twin will age slowly. Like most paradoxes, this occurs because of faulty assumptions. This one happens because one twin undergoes acceleration while the other does not, something that was not taken into account when this twin-paradox story was invented.

I have now read the whole explanation and the above bit is the only section I understand completely! There are other bits I sort of follow, but I think you need to read it for yourself!

Simple version: Twin A stays on earth, Twin B makes a roundtrip to interstellar space at a speed close to the speed of light. When Twin B comes back to earth, we see that Twin A is older than Twin B. It's a paradox because twins are supposed to always be the same age. Why does this happen? Because time slows down the faster you go.

The idea is that one twin goes on a near light speed
journey and returns older than the other. That is not
the paradox part, though, that is a simple and well
understood relativity problem.

The paradox is that, if motion is relative (as relativity
professes), then in each frame of reference, one twin is still and the other is moving away (they both would see the other aging
faster!).

The fix, as mentioned above, is that the phrasing of the
question ignores that they are not in equivalent frames of
reference since one must undergo acceleration when the
rocket speeds up, slows down, and turns around.

Suppose you had a twin brother, and you were both scientific geniuses. You and your brother created a ship that can accelerate to almost the speed of light (say, to around 95% of the speed of light). You volunteered to go exploring our nearest star, Proxima Centauri.

As you hopped into the spaceship and traveled off at almost the speed of light and sped to Proxima Centauri (which is 4.5 light-years away, so we'll say it took you 4.8 years to get there, because you're not quite going the speed of light). Now, your round trip takes 9.6 years to complete, and you arrive back at Earth and greet your brother. You find that the man has aged 9.6 years... but you've only aged a few weeks!

This is called the Twins Paradox, and it has to do with a relativistic property called time dilation. It states that as you approach the speed of light, time slows down. So, the faster that you go, the slower time seems to pass. Because you were going incredibly fast, time seemed to slow down. But, the cool thing is that you'd never realize it. For you, on the spaceship, it seems like the trip took only a week or two. However, for your brother left behind on Earth...

...it took you nearly ten years to return.

I'm tellin' ya, sometimes relativity is freakin' crazy!

Hope this helps!

you go with answering, in below 10 words, a idea that has exercised the acceptable minds over the only accurate ninety years!! Oh that existence changed into that straightforward! There are, in truth, 2 theories of relativity: the certain and the final. to discover their outline, study Einstein's conventional e book, "Relativity" revealed by using Methuen & Co Ltd. I doubt that your study little from the solutions given the following. one component i'd caution you about: the idea of relativity isn't e=m^2

This is ridiculous as no one could ever prove it. But then again its just a theory.
Is it like saying if I kept up to the speed of light I wouldn't get old? But coming back I would be twice as old ????

So if I died I would be dead, but if I didn't die I wouldn't be dead ? Peace & Love Bro !

if you had twins and sent one out in space while the other stayed on earth, the one who went out in space would be younger than the one who stayed on earth.
