Time does not exist?

hehehe! sorry bro, just making a point about einstein theory. anyway, even the speed of light is way out of topic in this thread so let's just let it rest

let's just go back to TIME which is the real issue here, so does it really exist? since you have thought about it therefore it must be in existence. to corrupt the famous quote of rene descartes 'cogito ergo sum', you think therefore you are....

Einstien's Theory of Relativity has everything to do with our concept of Time. According to the theory, Time and Space are enfolded in this universe. Relativity gives us a universe that is dynamic, a space-time fabric of reality. Gravity is nothing more than a 'dimple' in this space-time fabric caused by mass or energy.

Relativity theory also implies that Time can be slowed down and can be destroyed (along in it, space). The faster you travel the slower Time ticks.

The theory also makes Time travel a possibilty, since Relativity considers Time as a variable, that theoriticaly it can be moved backwards.

And again this is all just a theory. No one has invented a time machine. No one has seen the space-time fabric behind the engineering of this universe. No one has slowed down time. No one has destroyed time. No one has traveled as fast as light. No one has rewinded time. No one has even applied this theory of relativity to create a machine that would be able to modify time as the user wishes. No one. Not a single human on Earth. This is a fact. Not even Einstein, the origin of this theory itself.

Of course, I would not hold my breath whether all of the above will be a reality in some distance future. For now, man's acquired technologies have not yet come to that point that we may able to begin to draft some sort of prototype. But one cannot just say with absolute certainty that all of this well not be possible in the future.

Relativity as a Theory, as well as science in general, simply describe to us our reality in an empirical manner, and one of it is the nature of Time. Since, we're talking about time, for me there's nothing that best explain the nature of Time than the Theory of Relativity, which has been subjected to a battery of empirical test and survived to become another cornerstone of Physics.

If the Theory has not yet come up all those things that you had mention, it does'nt also mean that the theory itself if either half truths or just a wishful thinking.

according to Einstien's Theory of Relativity we can see our past. theory ra pud.. f naahan mo makahibaw unsaon kuno niya.. post lng mo dri.. ky bcn d sad mo nahan kapoy nya type..hehehe ibinisaya ra nako ky lisod englis..hehehee

ay bcn kabalo nmn mo ani.. nindot baya.. hahahaha

according to Einstien's Theory of Relativity we can see our past. theory ra pud.. f naahan mo makahibaw unsaon kuno niya.. post lng mo dri.. ky bcn d sad mo nahan kapoy nya type..hehehe ibinisaya ra nako ky lisod englis..hehehee

Memory man siguro tawag ani bai, hehehe. Seriously now, kanang mga objects in outer space, puro mga past kana, kay lagyo man gyud kaayo.

Since light travels at a finite speed, it takes time for light from these celestial objects to reach us. For example, the sun is eight light-minutes away. What we see of the sun at any moment is the sun 8 minutes ago, since it takes light 8 minutes to travel from the sun to the earth.

Some celestial objects are so far away, like quasars, that what we see of these are what these actually were billions of years ago (they think quasars are baby galaxies). The astronomical telescope is thus, the closest thing we have to a time machine. It also gives us the opportunity to glimpse at the evolution of the universe.

The slowing down of time is fact in nuclear physics. Subatomic particles that only get to live for a short time get to live longer if you accelerate these to speeds near that of light (in vacuum). This phenomenon is only observable to speeds very near that of light. Anything less is not readily measurable. Hence, everyday observations do not demonstrate this phenomenon.
---

Some speculate that if time slows down as it approaches the speed of light (and stops at the speed of light), perhaps time can travel in reverse for an object, if its speed of travel is beyond that of light (theoretical particle called tachyons are postulated to travel only beyond the speed of light).

However, the speed of light cannot be achieved by objects (possessing rest mass), since mass also increases dramatically as its speed nears that of light. This means that it takes infinite energy (to move an infinite mass) to make an object travel at the speed of light (unless, of course, it was light in the first place).

It may be “more possible” to “travel to the future,” than it is to “travel to the past.” However, you cannot come back.

Since time slows down if you travel near the speed of light (in this case, relative to Earth) for say, one year, such that you achieve a time dilation of 10%, then when you return, you would have only aged one year, while everyone else aged ten. You will, in effect, be going to a future nine years ahead.

huhuhuhu nalingaw ta ko is2rya ana.. kaw nmn nuon na is2rya.. nalingaw nlng nuon ko basa..
heheheheeh sak2 ka..

so lets make a ship and verypowerful telescope na makatravel faster than the speed of light and tanaw ta sa past na2..hehehe

OT: i wana c my lola and tatay back ka2ng buhi pa cla..

@geoseph: correct gyud ka bro :mrgreen:

Sorry, nonoyantoine bai. I don't doubt maistorya pud ni nimo (ug ang uban pa). Salamat sab.

so lets make a ship ang verypowerful telescope na makatravel faster than the speed of light and tanaw ta sa past na2..hehehe

Bitaw no (karon ra ko ka-encounter aning idea), theoretically pwede pud. Nice one. :mrgreen:

Thanks Divemaster bai. Nice info.
