theoretical, is the construction of a time machine possible regarding the laws of physics?

Question

please explain why or why not.

Answer 1

There is a very basic reason why it is impossible to "travel" through time. The answer is found in the physics trilogy: E = mc2, c2 = E/m, and m = E/c2. Notice in these equations that the only value that does not change is that of the "c2" one. This value is that of a particular speed and energy value. c2 = E/m describes a field of physical time - it also describes the origin of a gravitational field. "c" exists as a value able to exist alone, and is a particular product of the mass to energy ratio. The energy in this instance is the heat energy contained within a mass.

Having said that "c" exists as an entity to itself, consider that all mass and energy are formed of this value. This value is that of physical time. It is what all forms of mass and energy are composed of. It is also the reason why all events pass from the present into becoming the past as they do. Notice there is no manner by which the value of "c" may exist as any value other than itself. It is unable to be compounded or reduced in value. This leads a person to come to the conclusion that all that exists to mankind is "present" time. All physical events of the past exist in present time - they've just changed into gasses and dust. The future is the present, it just hasn't been put together yet.

Shrillary is a hack pollitician who's time is previous. each and each of the politicians seem to do now days is seem for the thank you to get thier call interior the papers for interest, as though individuals are so stupid that they won't remember the dumbest strikes. It took almost 2 months after Jan Brewer signed that bill for the fool illegals and unlawful supporters to get the clue.(or learn how to verify) that there became no racial profiling allowed. we've now purely as many moron's claiming Arizona would not have the suited to maintain federal regulation. incorrect lower back you slack ***'s which could no longer analyze. take a seem at; The unlawful Immigration Reform and Immigrant duty Act (IIRAIRA), valuable September 30, 1996 they further section 287g which of course types a partnership between states and the feds to uphold the regulations. And ARIZONA is on the record.

Answer 3

The electron's antiparticle is the positron, according to certain physicists. Some say that the Feynman diagram for beta decay is showing that a positron is an electron traveling backward in time.

Paul Nahin states in his book, "Time Machines" on page 155: "Just as momentum and space are complementary variables (momentum conservation is the consequence of space direction invariance in the laws of physics) and just as a particle can reverse its direction of motion in space if it loses enough momentum, so a particle can reverse its direction of motion in time if it loses enough energy. This follows because energy and time are another pair of complementary variables. (Conservation of energy is the consequence of time-direction invariance in the laws of physics.")

I do not believe time reverses--I think the physics / mathematics are a construction of wishful thinking.

Answer 4

No, but one does exist. It's activity layed they ground work for it's own development, so it's really difficult to say when it was actually 'constructed'. It doesn't leave a wake, so it's passing goes unnoticed. I suspect it operates in a closed loop, that extends from about 4000 BC, till about 3000 AD. People that have not been affected by it's activities tend to see time as linear, and possibly infinite. Those most affected, percieve the world as a mobius, and quite finite....

Answer 5

It's totally impossible. If you went back, just think you could get somewhere before you left to go there and even before you were born. Potentially, using time dilation, you could slow your time with respect to where you are now if you travel close to light speed but you could never return to where you left and time would still seem to pass normally for you even at close to light speed..

Answer 6

Based on the current laws of physics, no. The speed of light cannot be exceeded.

Answer 7

sort of. it is definitely possible to travel into the future by slowing down your time relative to where you want to go. see here...

Going backwards in time is arguable at best. see here.

Answer 8

yes , it can be succeed. i don't know the exact reason but Einstein made a successfull experiment on time travel. If he believed so, who am i to disagree?
