Newton's laws do not distinguish the before or after. Are fully reversible. A pendulum without friction and with a perpendicular angle to set in motion and you can predict its position at any future time.
but also any other movement, even planets. And also one could know what was the position of a PALNet in the distant past.
In this first stage of determinism, the universe was a machine in which the future could be predicted. Enough to have enough information on the current situation, to know even our behavior at a future time. That idea calo deeply due to the long tradition of seeing and of people who claimed they saw the future. And it is part of the lack of freedom imposed people. The fatalism fate has to do with the same Newtonian vision. We can say that there was no difference between the vision the reality of Newton and the Greeks. And yet this embedded in our language and personality of many people "" today did not have to get up " I play, it had to happen ." That is the idea that nothing can be changed. It has more to do with societies where social change is slow. The caste system in India, clearly stratified society of Greece, or the feudal era helped to maintain the same society. The farmer was born to a farmer, and so would his son, the idea of \u200b\u200ba change in their lives was unthinkable.
In Newton's theory was uniform space, full of things like stars, planets or comets. But the space was a place like any other. That led to
Lagrange to regard time as the fourth dimension and therefore space and time were equal. That allowed the trend in the late nineteenth century to make the equations of physics to hobble geometric, in which time did not vary. Under this scheme
mental
lived one of the greatest geniuses of that time; HG Wells can not speak of time machine or time travel without naming it. That novel was not only a landmark in the literature esaepoca, but it also was ahead 20 years to the theories of Einstein do not know if Einstein read it, but not to give his mania credit to anyone I do not doubt that his conception of space-time was taken from the novel. Since only gave mathematical form to what Wells had said.

"any real body must obviously
energy expansion in four dimensions, but due to the natural infirmities of the flesh
tend to overlook this fact.
Actually there are four dimensions: three in the paln of space and fourth time. However there is na
HACR trend unreal distinction between those three dimensions and
this, it happens that our consciousness moves intermittently in one direction
this from the beginning to the end of our lives "

This is where Wells points to one of the key points of the theory of relativity.
not trivial mathematical difference between the ideas of Einstein and the rest and that's where all his genius shine. In normal space to calculate the distance between two points using the Pythagorean theorem, the Cadre of the total distance is the sum of the squares of the other distances. The space-time
einteniano the square of the distance "metric ** the sum total of the square of the length over the square and the width, but the square of height less the square of time. Therefore
the metric takes time a negative sign and is not on par with the space. That makes one wonder if the time is flowing or not this theory. And the time this theory has a geometric character and space.
can say that the real time study began with Einstein, he was who would take my time tabu status and begin to understand. All current definitions of time have their origin in the theory.
And also is attractive as this theory allows time travel . And all current attempts to travel through time are based on their theories. But are they true?
In Einstein's theory of gravity is the geometry of space, and anything in it deforms, so space is not the same everywhere. And the body takes the lead role in the formation of space-time, as this may affect the time and space.
That to me looks very elegant and which thus left to wonder about gravitation, we can draw the conclusion that gravitation is a consequence of the existence of mass. And this mass can to stop the aps time. Some of these machines
time Tipler rely on it. Let's see if I can explain without contradicting many times
When a large mass (here we enter the concept of density, therefore a very large mass does not necessarily occupies a large volume) and we assume that we space as a grid all the same size in two dimensions, length and width. If we introduce a mass in that space, crews are deformed, becoming smaller in the vicinity of the mass and longer as you move away from it.
If crews are smaller and the time to go lower. So time goes by faster in the vicinity of the mass away from it. For me one of the consequences of the theory of relativity is that the speed with which time passes is 300,000 km / sec. That's what takes a moment. However, if the mass is very large the time came that the crews have a size of zero, and therefore may not spend time in that area, because living in an eternal present. This area is believed to be around a black hole, and is the reason why is black and for that reason nothing can get out.
is for the time.
There is an area where time does not pass to another if it passes. The same theory of relativity allows the existence of particles faster than light, this is the tachyon problem. These particles would travel from future to past, and would have negative mass, as well as negative energy. In fact its mass would be imaginary, as it would be the square root of minus 1.
And that's hard to imagine even with LSD. Tipler
The machines are based in large rotating cylinders of unimaginable density, similar to that of a neutron star and if the lake enters the cylinder through the space-time would be so distorted that could make a trip back in time and space at a speed greater than light, but if you pass it, only narrow the area to be traveled.
far so good. All this has been proven time and again. And we stayed with that time is just another quality of space. Time does not flow
this. But is all of that Amner? What happened to gravity? Is it just another attribute of the masses?
This continues, still do not know many things, not because the past events so different from future events. Venezuela

That time is the time I

I just read a report of a physical which is sure you can make a time machine, his idea is based on theories Tipler and Penrose's theorem trapped surfaces (which is commonly called black holes), aunue in the article I read said nothing of these references. I do not know the reason.
The time travel is a fascinating idea. But before time travel What the hell is time?
We are familiar with the sometimes say we have no time or malgastamo time. And the perception of the brain over time is quite erratic. 55 minutes having sex with nicole Kidmann may seem like just a blink. But if you put your hand in the fire, 1 minute can seem like an eternity.
The brain is not a good judge of what is the time. Alcohol and other psychedelic drugs also alter the perception of time more radically.
So Where are we going to travel?
And the issue is complicated if we go to Cultural Plan. Most ancient cultures had the idea that time is cyclical, the Aztecs, Mayans, Incas, Jains (hence the image of the snake biting its tail). The idea of \u200b\u200bthe Greeks is most confusing, if you read his epics we have them, Achilles, Ulysses, Zeus live in a timeless place where time has no importance. Then through the influence of the Persians began to get interested in cyclical time. Democritus gives us the image of the flowing river as a metaphor for time. InMage
This is a forward who later took the Judeo-Christian religion, to create the image of rectilinear time, that image was the one attached to the reason and the money allowed the revival and then the industrial era, since it is easy to stretch a little over the image and imagine we progress over time. The future will always be better than last .
A civilization with the idea of \u200b\u200bcyclical time as the Indian would never industrialization or rebirth, and less to reach the planets and moons, as their own schemes where they develop their ideas, that is not permitted and is therefore unthinkable.
In our own civilization, there were attempts to implement the cyclic time, which comes to mind right now is but also Nietzsche, Borges or Milan Kundera (in his novel "The Unbearable Lightness of Being") but the same science and the strength of the theory of evolution reinforced the idea that the whole future is better and many people even today use the word evolution as synonymous with progress, which will improve, when in fact evolution does not say that.
So What is time?
In science, time appears in many equations that describe phenomena newspapers or where time is of essence. An example is the equation of speed, which is measured as a function of distance traveled in a time interval.
The first s equations where time began to make important was to Galileo, and reached its climax with newton. And
amisma idea of \u200b\u200btime is also in the theories of Einstein, this one makes an expansion. In physics, the branch of science that tell us something about the weather, says that there is no past or future, so the idea of \u200b\u200btime travel into the past or future has no meaning in science. There is only before and after a fact the battle of Carabobo was before I wrote this, but not in the past as this in the future of the birth of Bolivar, or rather after the birth. We have a problem
How will travel and where you are traveling before or after?.
As I have said that people do not actually read, I then for no more than it proved necessary crabs
