Twin paradox itself is a big sollu... Daani meeda modification koodaanaa! There is no paradox. The reference frame cannot be accelerating or decelerating. So the traveling twin cannot be a reference frame by himself. dEvO mahEsh roopENa: Superstar Mahesh Rocks! | ||

just like we adjust our clock and synchronize our calendar periodically, relativity talks about how to synchronize clocks in different locations....Does it mean time is changing? | ||

we can measure time locally using an agreeable standard....a clock with light oscillating between two mirrors can be used as measure of time... if gravitational field effects light make a gravity shielded clock or use equations to make the time sync with a standard clock......that's waht relativity is all about.....it doesn't have anything spectacular....it has nothing to do with aging or time travel | ||

why so much fascination for this theory.....with physical defintion of time in physics it could be a new way of looking at their physics or maths....it has nothing that can change the world....certainly it can't alter time.....all time travel based on relativity is nonsense and humbug.....if any physical preocess changes because of gravitation and if you measure time dilation using that process, you could possibly become physically more older while your measurement of time dilates......such perceptable measurement of time dilation can be done using a simple pendulam on the surface of earth itself no need to travel with high velocities | ||

what i understood by time travel is.. some object, starting a journey at some instance of time (t=t1) will end its journey at some earlier instance of time (t=t2 and t1>t2) or did i miss anything related to time travel? ikkada naakoka doubt  suppose that an object moved a distance "d" with a speed "v" (both being positive scalars) now, what should be values of d and v, so that "t < 0"? (ofcourse, t = d/v) | ||

If physicists defined time physically with relativity they should explicitly say so...what is time dilation, ageing, younger nonsense....are they sure the travelling twin doesn't physically age more while the time measurement of twin on the ground dilates | ||

I think time is only defined when it is constant so far. Meaning when i'm talking to you we both see the same perspective. If we are at different speeds which will effect time(humanly possible reading) we cannot communicate. | ||

what is the meaning of time ?....How is it defined?....what type of time is relative to the speed? | ||

Time is relative to the speed which one an observer travels | ||

time relative ani kothaga telusukundedhi enti....america lo time india lo time different ani eppatinundo telusu kadha?....if because of gravitational difference some physical process changes....Does it mean time dilates?...if that is so we don't need atomic clocks to measure such difference....a simple pendulam at different locations above earth surface will suffice | ||

their result is in nanoseconds bro........i don't know how they measured what they mean....here is what Einestien says http://www.fourmilab.ch/etexts/einstein/specrel/www/ "It might appear possible to overcome all the difficulties attending the definition of ``time'' by substituting ``the position of the small hand of my watch'' for ``time.'' And in fact such a definition is satisfactory when we are concerned with defining a time exclusively for the place where the watch is located; but it is no longer satisfactory when we have to connect in time series of events occurring at different places, or--what comes to the same thing--to evaluate the times of events occurring at places remote from the watch. We might, of course, content ourselves with time values determined by an observer stationed together with the watch at the origin of the co-ordinates, and co-ordinating the corresponding positions of the hands with light signals, given out by every event to be timed, and reaching him through empty space. But this co-ordination has the disadvantage that it is not independent of the standpoint of the observer with the watch or clock, as we know from experience. We arrive at a much more practical determination along the following line of thought." | ||

I am not an expert. time dilation seems real. its just not about perception. please check the results of some experiments: http://hyperphysics.phy-astr.gsu.edu/HBASE/Relativ/airtim.ht ml#c3. | ||

calling relativity experts.........is time measuerement of something moving relative or time itself is relative......How is time defined in relativity? | ||

Isn't entropy a measure of absolute universal time or kaala in indian philosophy.....just becuase measurements of definitions doesn't match though nothing physically changes, Is it proper to consider it a relative quantity? | ||

Please don't think i am trying to be extra smart or showing off......i am trying to recollect and re evaluate whatever i have learned or thought i have learned till now..........i get some genuine questions......time is physically defined in relativity.....it's defined as distance travelled by light .......imagine the twins in twin paradox has a light clock, it has a light beam that travel back and forth between two mirrors seperated by a fixed distance, so number of times light beam moves back and forth is a measure of time.....since speed of light is constant for all observers it should measure same time.....if the twins enquire time from each other when they meet after their journey they should exchange same time......so, who is becoming older here?.......what is this nonsense that's being fed to gullible public |
