We all move at the Speed of Light

welcome back to science Creek today it is possible to go faster than

light

we often hear that the expansion of the universe accelerates some objects faster than

light

itself in fact some objects see that the distance between them increases faster than the

speed

of light but this is due to the expansion of the universe itself, the underlying network upon which all entities are placed, this network is constantly expanding, so the distance between objects is constantly growing, it is not actually a

move

ment true, it does not allow us to send information faster than light, except For the expansion of the universe, is it possible for an object to

move

faster than light through space?

The theory of special relativity allows us to understand the fact that the

speed

at which an object moves in space modifies the flow of time of that object the faster it is. The object moves relative to the observer, the more the time of the object itself slows down compared to the time of the same observer, if this same moving object were wearing a clock, then the time it would take for the arms of that clock to complete The circle would be larger and the time required. by those of an identical clock that would be at rest in the object's environment, so that the faster an object moves in space, the slower it moves in time.

To quantify this situation, we can try to draw a very simple graph that represents the passage of time in relation to the speed of an object. For an object at rest with a speed of 0, time passes at one hundred percent of its normal rate in turn. For an object traveling at one hundred percent the speed of light, time would simply stop or in other words go with zero speed. Naturally, we might think that if time can stop when we reach the speed of light, it would be possible. take a step further and go back in time if it were possible to travel even faster than the speed of light. speed of light, the more we accelerate beyond the speed of light, the faster we will go back to the past with a negative time flow.

This is an idea that at first glance seems completely plausible and even very attractive, regardless of how it is based. On a fundamental assumption that should not be left unquestioned, is the fact that we have extended and connected both points by a straight line; in fact, there is a certain curve that connects these two points and on which all objects in the universe are placed, any form of matter, any object can be found on this curve and as soon as it starts moving at a certain speed, the Time relative to that object will inevitably flow at a certain rate in a kind of time that slows down in the same way for all objects, given that they have the same speed.

When we look to see if this curve is really a straight line, we discover that a An object moving at 50% of the speed of light sees its own time pass not at 50% of the normal speed but at 87%. of the normal rate of the flow of time, in the same way, an object moving at 80 percent of the speed of light sees its own time pass at 60 percent of the normal rate and an object moving at 25 percent of the speed of light he sees almost no difference in his own time. passes through 97% normal rates the curve that appears before our eyes turns out to be not a straight line but a quarter circle and any matter contained in the universe can be located somewhere along this quarter circle just like our straight line, this curve can be extended to form a complete circle to the left of the graph, the negative velocity simply corresponds to the velocities obtained while moving in the opposite direction if moving to the right gives a positive velocity of one mile per hour, For example, then moving with a negative speed of minus one mile per hour is simply equivalent to moving to the left with the same speed to begin with, we see that it is not possible to go faster than the speed of light nor to go beyond the speed of light. of 100% of the observer's time flow, in fact, not even during a hypothetical object that would go back in time, that is, with a negative time flow, it remains strictly impossible to go beyond the speed of light because all objects are confined in this circle, the question then is not to know if it is possible to go beyond the speed of light, but rather to understand why such a thing is impossible, why our curve takes the shape of a circle And what's special about the speed of light, let's start by looking at the particular shape of this curve: a circle.

One of the key properties of a circle is that all the points that make it up are located at the same distance from its center, for any object the only meaningful measurement is neither the speed at which it moves nor the speed at which it flows its own time, but rather, the distance from the center of the graph, this measurement takes into account both the movement of the object in space and its movement in time, it is a kind of unification of the two speeds, we combine the movement of the object in space and time, this is speed in space-time whatever the speed of an object, whether it accelerates or decelerates its position, then the graph will change but its distance from the center will always remain the same this measurement is a Universal fundamental constant that governs all entities in the universe.

It is this same measurement that we call the speed of light. It is important to understand that the speed of light is something fundamental. Its importance does not come from the fact that it is the speed at which light travels. Its importance comes from the fact that in space- When we consider both the Space, like time, is the speed at which all objects in the universe move. With this in mind, we can better understand the phenomenon in question. Objects cannot go beyond the speed of light because they actually move without a precise speed. In all circumstances, the only thing that can change is the way an object's velocity is distributed in space and time.

If the object is high enough on the graph, it gives much of its velocity to time and very little to the space of its own time. It flows at a speed very close to normal but moves very slowly in space. This is the type of behavior exhibited by objects in our everyday lives that are either at rest compared to us or moving very slowly compared to the speed of light in space. On the other hand, if the object is more towards the lower right corner of the graph, it gives more speed to space than to time.

The fastest objects in the universe move very fast in space and, consequently, very slowly in time, they actually evolve in time. slow movement compared to us, this is the case of light in particular, which gives all its speed to space without leaving anything to time a light particle moves extremely fast but its own time does not pass at all if a light particle He carries with him a hypothetical clock. The arms of that clock would not even move an accelerating object. It does not actually gain speed. It will only convert its temporal speed, which allows it to move through time, into spatial speed, which allows it to move through space.

This is equally true The other way to avoid the deceleration of an object is that which converts a part of its spatial velocity into temporal velocity; it decelerates in space and, consequently, accelerates in time; In general, although your speed and spacetime have remained constant, you are still moving at the speed of light, it is just the distribution of that speed in space and time that has changed. To conclude, this representation in the form of a graph has many advantages, since it is very visually attractive and allows us to intuit certain phenomena, for example, we could ask ourselves whether or not there are objects at the bottom of the graph; intuitively, these objects would be going back in time.

Since its time velocity is negative, following this reasoning we could postulate that there is a specific type of particle in the universe that would be located in this part of the diagram, this type of particle is what is commonly called antimatter. Antimatter particles have identical properties to regular particles, only their electrical charge is reversed. They are essentially the symmetric counterpart of ordinary particles. The part at the top of the graph is. where normal matter is, while at the bottom its mirror image is the world of antimatter, as for the light particles, also known as photons, these are their own symmetrical counterparts, being on the horizontal axis, they are its own antiparticles, it is important to be cautious, however, since this entire representation is based solely on the model of special relativity that holds only in an empty and perfectly flat universe, in reality our universe is not flat, it is full of stars and planets that distort the geometry of space-time in 4 dimensions under these conditions. we must look at the theory of general relativity in general relativity gravity does not exist, it is the curvature of space-time that naturally converts the temporal velocity of an object into spatial if an apple that was originally at rest falls from a tree, this It is due to the fact that its evolution in time has become an evolution in space, that is, in speed, as a consequence of the curvature of space-time that is due to the Earth if we observe an object located next to an object from afar. massive entity like the Earth. then the graph associated with that object will begin to distort next to a black hole the circle becomes so distorted that it becomes smaller and smaller as the object approaches the horizon by the time the object reaches the event horizon the circle has contracted by complete this means that the object has no room for movement from our point of view it remains motionless at rest with the surface of a black hole when we observe them from afar all objects that fall into a black hole end up appearing trapped on its surface but for the object itself this phenomenon is just an illusion from its point of view it is possible to cross the horizon of the black hole and gradually continue falling towards the central singularity however for us observing the situation from the outside all the information contained in this object slows down until reach a final stop and remain fixed on the surface of the black hole.

One of the most important consequences of this phenomenon is that the entropy of a black hole, that is, in a certain sense, its information and temperature, is completely distributed across its surface.
