To answer that simply is.. if time is indeed true, then we are now stating that there is absolutely a beginning and an end to all that exists. As far as I know, that is a question that has yet to be answered and therefore any theories that we currently have can all be shot down.

Einstein came up with his theories based on facts that were available given the science and mathematics available to him at that time. We have moved well beyond those limitations in thinking since that time. His theory is a great paradox because to date it cannot be proven nor disproven.

I think that we are limiting our own abilities to further understand what is going on when we limit our thinking to set rules such as time, 3 dimensional views etc... Just because we can't see it, doesn't mean its not there, and once we finally can see it, how is that going to affect everything we took for granted as being true.

travelling forward?? if you go back to the same place it would appear that way yes.

Just watch this movie. :1orglaugh

Einstein's Theory of Relativity to be Tested

07.15.03

Albert EinsteinNASA is preparing to put Albert Einstein's Theory of General Relativity to the test. The Gravity Probe B (GP-B) spacecraft will use four ultra-precise gyroscopes to determine whether space and time are distorted by the presence of massive objects.

Albert Einstein conceived the Theory of General Relativity.

In order to carry out the mission, GP-B will measure two factors - how space and time are warped by the presence of the Earth, and how the Earth's rotation drags space-time around with it.

At Stanford University, ideas for Gravity Probe B began to take shape in 1960. A physics-engineering team was formed, led since 1962 by Francis Everitt, now GP-B principal investigator. So began a long process of design, analysis, and exploratory research funded by NASA and supported technically by NASA's Marshall Space Flight Center in Huntsville, Ala. The GP-B spacecraft was designed, integrated and tested by Lockheed Martin.

The consensus is that only 3 or 4 people on Earth REALLY understand relativity and I doubt any of them read Gfy.

No.

My understanding is that the levels of energy required would be so high as to essentially be infinite, and therefore unobtainable.

It has been tested and to some degree substantiated with particle accelerators. Keep in mind there's huge disconnects with current theories at the moment but if you really want the simple simple breakdown of the specific aspect of the theory that you're talking about it would be this:

1) As your velocity approaches the speed of light you move through time more slowly from the point of view of an observer.
2) As your velocity approaches the speed of light you shrink in the direction of the vector from the point of view of an observer.
3) As your velocity approaches the speed of light your mass increases.

Obviously this is way oversimplified and there are far more up-to-date theories on this process now which attempt to bridge the gaps between relativistic physics and other forms of it but yea...

:1orglaugh So true.

50..........

Wrong theory of relativity :winkwink:

:1orglaugh

The part I don't get is how does one know this? How does one come to accept the statement as a given or truth. Was it first conceived from a mathematical proof or equation?

It's been years since I took Grade 12 Algebra & Geometry and when I did, I got a C+ grade in it, lol. Mind you, I was a slacker. I have no recollection of what a vector is and how to apply it here:(

If a vector is a straight line, I agree you shrink as you pass an observer. This happens when a car passes you and it gets smaller the further away it gets from you. I have no clue if that's how to interpret the statement. hehe:(

Ok I'll accept that. I still just don't grasp how that relates to time.

Actually it's not exactly the speed of light... it's more that the fastest you travel, the slower time goes. They tried to mesure it with nuclear clocks on TGV (fast speed trains) and it seem that his theory was right...

Wrong forum :)

How can you be at all conclusive on his theory.

First of all, the speed of light is a calculation of distance and time. The only thing that this theory can rely on is OUR interpretation/perspective of distance and time. IMHO to even remotely assume that this theory of relativaty could be true is a lack of thinking outside of the box. There are so many more variables that are not being considered in his theory. This theory was developed based on the concept that we live in 3 Dimensions.

He may have presented a better way of looking at things based on the existing knowledge at the time, but i think there are far too many holes to be able to consider his theory as accurate and true.

No-one knows for sure but I think age is relative to size, health, and your environment.

Flys live 24 hours but go through the physical maturities of living 40 human years. And there is a general size to living ratio for species.

So far as explaining how time stops when you go the speed of light?

This is based on quantum physics. Simple put there is no spoon only what we think is there that works like a spoon. maybe at the speed of light life moves faster then thought so we can't realize what's happening enough to age.

just rambling :1orglaugh

I think the most amazing thing Einstien realized is that size is infinite in all directions. Maybe connecting the smallest level to the end of the galaxy in some sort of reversed palerity world. We spend so much time on space but galaxies can live evolve and go extint all in the mold of a peice bread left in the sink.

very interesting topics!!

woj's bot travelled forward in time

It's been proven with partical accelerators where they accelerate a radioactive particle and measure the halflife decay of the material to gauge how much 'time' has passed. They have also done experiments with atomic clocks in high speed aircraft where the ones in the planes tick 'slower' than the ones on the ground.



= = = = = = => turns into
= =>
You shrink, but only relative to the direction that you're going. Note that the width remains the same, only the length changes (attempting to do this with a 2d model so work with me ;) )

No that's just a matter of distance, what I'm talking about is an object actually getting smaller (again only from the point of view of an observer) depending on the speed at which it's traveling. If you could hypothetically take a picture of a car moving near the speed of light as it passed you even ten feet away it would be about as wide as a pin viewed from the side.
(ie you're looking this way at the road the car was traveling on -> || )

It doesn't other than the fact that according to this theory both are variables which are dependant on our velocity and therefore relative to other moving bodies.

No one is being conclusive, he asked for the theory according to Al and this is the theory according to Al. It has since been updated.

Actually one of the suppositions that this theory puts forth is that the speed of light is a constant, and therefore can be used as a benchmark against our relative prespectives.

That's so cool. It's really weird because I don't fully understand how this happens and makes me second guess how everything I take for granted in the world actually works, lol.

I should have paid more attention in physics and calculus. Maybe if I re-grounded myself in the principles of light and matter I could wrap my head around this. For now, it reads like Greek to me, but the proof is undeniable.

I saw some thing on the discovery channel. They were talking about how they synced watches together before astronauts went into space. When they came back, the watches were just a few minutes different. I think it worked with digital and analog watches.

If you have two atomic clocks, one at sea level and one at "altitude" say in Colo., the one at altitude runs slower than the one at sea level. Since time runs slower for the clock at altitude because it is traveling faster, ppl that live at altitude thus live slightly longer reletive to ppl at sea level.

this is the thread of the year so far

;]

i spent hours discussing this with one of my friends once, not a simple concept :)

Theory of Relativity:

Time seems to go relatively slow, when you spend it with drunk relatives, on holidays... :)

right over my head

Time is relative to where you are. For example mars takes longer to cirlcle
around the sun. So if you lived on Mars you live longer,but you will not know the differece. Another example would be while you are driving and look at how much time has passed and how long did it seem to you.

LMAO

Time is NOT relative to where you are. :1orglaugh


The second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom. This definition refers to a caesium atom at rest at a temperature of 0 K.

what if c.a.t really spelled dog?
