Why does mass slow time?

[HeairBear]

More mass = slower time. Some ancient Sumerian tablet said that too! The planet Nibiru is several times larger than the Earth which explains why their time was slower and made them seem to live longer. It all makes perfect sense now!

The clocks on Earth/Space digital?  Maybe electrons flow faster without gravity (or mass)?  If you have a mechanical clock on Earth and in Space synchronized.. I bet they stay synchronized.

An atomic clock in orbit around the earth will not stay synchronized to an atomic clock on earth, the clock on earth will show less time as compared to the clock in orbit.  If you have two atomic clocks orbiting the earth in the same orbit (spacetime), then they will stay synchronized.  If the two atomic clocks are in different orbits, then they will show different time, the clock in the higher or furthest orbit will show more time than the clock in the lower orbit.

Take a look at these 2 questions.

1) When an object is orbiting the earth, then why does it not accelerate as it is orbiting?
2) When an object is not orbiting the earth but falling through to lower orbits then why does it accelerate?

In both questions the objects are under the influence of gravity or the earth's mass/energy, but you have different effects as far as acceleration is concerned.

My answer to question 1 is this: The object does not accelerate because the path that the object is following around the earth has the same curved time and the same curved space. A lower orbit will have a different curved time and a different curved space, etc.

My answer to question 2: The object will accelerate as it is falling through to lower orbits because there is a different curved time along the path that it is falling through. It is the space/time difference, that causes the object to accelerate if it doesn't have enough momentum to stay in that orbit.

When we see an object that curves along its trajectory path due to a large mass, then we are able to see that the space is curved. When we see an object that accelerates towards a large mass, then we are able to see how time is curved, we see the time being curved in the acceleration of the object.

Also consider this:
A black hole has so much mass that time gets slower as you approach the event horizon. It is not the velocity or acceleration towards the black hole that causes time to slow, but it is the mass that causes time to slow. If you increase your velocity or acceleration then you increase the energy/mass for that object. Since the energy/mass has increased then time has decreased. If you are on an object and the object's rest mass is large, then time will run slower on the larger rest mass object as compared to an object that has a small rest mass, just like what HeairBear said.

There may be physical forces in the universe that cause clocks to operate at different rates under different conditions, but that does not mean time changed. it only means the clocks changed. For example if I pound on a clock with a hammer and make it stop did I stop time? I don’t think so.

ok ok ok ok !!!

I have heard enough already ..

Number one question :

WTF is time ?

ie: you cant collect a bunch of seconds and call it a minute.. because those seconds dont exist beyond the moment, correct ?
So if you wish to aggregate or quantify the property time what is it you are sampling other than an idea ?

Maybe i can explain this better .. but I believe some will see the point regarding time and whether or not it is a participant.. ummm maybe ?


Or maybe it is explained best here.

I disagree unless that planet is traveling near relativistic speeds. time is the virtual particle sea flowing thru the mesh of all atomic nuclei throughout the universe. I said nuclei because even the electrons orbiting the nucleus are already knee deep in time which accounts for uncertainty principle - from the electrons perspective they are being smoothly displaced by virtual particles from their intended path to the proton at the nucleus. From any other perspective the electron appears to be jumping around in time because it is intercepting the very stream of particles we experience as time in 3d before it reaches "NOW". Now is  a 1 nuclei wide dimension at 90 degrees to normal space which means the "Present" has a volume that equals the entire cubic measure of the universe multipled by the average radius of a nucleus and would be "quadric" instead of cubic.  AND that is ONLY the present! because once we can use "twisted" molecules like hydrinos to claw away from normal space the quadric universe will allow us to trave at another 90 degrees in paralell with the time line ... which then means that quadric volume essentially gets squared! Now for some cold water -these are my speculations and I could be totally hosed (but I don't think so)
