I've done it before. I can see it. It still hurts. Just run multiple sims and senarios and relate them. Ow.Must say, the first time that someone thinks of time being the measurement of change it takes a while to sink in.

No, moving matter from the present to the past doesn't 'create' matter any more than moving matter from the present to the future would create it. It's a whole; past, present and future.if you could go back in time and meet yourself, then you have managed to create matter. This is completely incompatible with current acceptable physics. So while mathematically time travel may be possible, physically you cant do it. Sci-fi has tried to get around this anomaly by implying your past and present self will destroy each other should they come into contact.
The only version of your self whose matter exists, is your present self. Your previous self is your present self. You cant seperate. If someone does manage to meet another version of themself, then they haven't achieved time-travel. Its more likely they have travelled to an alternative universe and there you can have 2 versions of yourself, because the version of yourself in that universe is made of matter from that universe.
The extent of our ability to time travel is limited to detecting electromagnetic radiation which was created at some point in the past and which reaches in our present. i.e we can "look" back, but we cant "touch"
Even this is isnt real "time travel" because we cant manipulate the em radiation's time componant. We cant detect the same photons we detected yesterday. Today we detect photons that left the distant galaxy the day after the photons we detected yesterday.
That would depend on time. If it is another dimension where all the matter past, present and future exists then no you would merely be moving your present matter to the past. If it's real change, whether from moving through another dimension or not, then as said you would have to reverse the state of matter. You can reverse it locally (on earth) or globally (the universe) but either way you would have to exclude yourself so there isn't actually a possibility of meeting yourself. If you don't exclude yourself you'll then be creating another you.if you could go back in time and meet yourself, then you have managed to create matter. This is completely incompatible with current acceptable physics. So while mathematically time travel may be possible, physically you cant do it.

I didn't say they are the same. From what we can gather they all have the same properties. If there are any differences it's undetectable.@ swa all electrons are the same, every single one in the universe and they are present everywhere in the universe at the same time, they only appear to be what they are when you look at them... quantum mechanics, throw logic and reason out the window
Hmmm zippy interesting points, but your point assumes the fact of the future is not made yet. You cant just assume that, because what if past present and future exisit at the same time? then you would simply be moving matter from point a to b within the dimensions of the universe. Your arguement doesnt hold for traveling forwards in time. Keep in mind there is NO definition of time, you cannot define the concept of time without using the word time or any of its units of measure. Also in the laws of physics there is nothing that says time cant flow in reverse, every single equation works equally well in the negative. It doesnt happen because of entropy and the concept known as the arrow of time, so if time is a dimension then its not absolute in direction
@ swa all electrons are the same, every single one in the universe and they are present everywhere in the universe at the same time, they only appear to be what they are when you look at them... quantum mechanics, throw logic and reason out the window
This is actually an interesting view of reality. It is a view that appears to implicitly follow from a 4-dimensionalistic (4Dist) view of reality as developed by Einstein. On this view reality is a single block of space-time and everything that exists have spatial parts as well as temporal parts.Hmmm zippy interesting points, but your point assumes the fact of the future is not made yet. You cant just assume that, because what if past present and future exisit at the same time? then you would simply be moving matter from point a to b within the dimensions of the universe.
I don't see any reason to throw logic and reason out when it comes to quantum mechanics.@ swa all electrons are the same, every single one in the universe and they are present everywhere in the universe at the same time, they only appear to be what they are when you look at them... quantum mechanics, throw logic and reason out the window
That depends on your definition of matter. The modern view of the concept of “matter” became prominent during the 16th century with philosophers and mathematicians such as Galileo and Renee Descartes. This view can essentially be summed up as:careful matter is not energy, I can destroy matter so by that notion the converse should be true.
You cannot apply the second law of thermodynamics to matter
Or one can say, (from an Aristotelian point of view) that when an anti-matter substance and a matter substance are introduced into a system both cease to exist and the underlying principle of change (prime matter) takes on a new form.hmmm interesting. Though if I take an anti-matter particle and introduce a particle of matter, they would obliterate each other with a 100% conversion to pure energy, and the matter is gone. Though I dont think I can obliterate the energy itself into well ... who knows cause no one has destroyed energy.
If you are talking about 3Dism vs 4Dism... I tried, it's a difficult but interesting area. The links provided most probably explain it much better.Dude really your so called explainations are a bit complexeven when you try to make it easier rofl... i didnt read it fully too tired
Not entirely sure what you mean by "conventional logic".and when it comes to quantum mechanics you have to throw logic out the window, that is conventional logic. Otherwise you wont be able to comprehend the randomness of an electron. In other words how can an election rotate clockwise and anticlockwise at the same time? or how can it be at point A point B and point C at the same time when the distance between the points is 500 million light years? logic will tell you thats not possible! I mean you are made up of atoms which have electrons and you are not present in CPT JHB and DBN at the same time are you? Instant information travel that negates space (quantum pairs) logic will tell you that its not possible that information cant just appear like that.... if you hold to your so called "logic" in quantum theory then it will prohibit you from discovering the truth. As it did for Einstein
careful matter is not energy, I can destroy matter so by that notion the converse should be true.

The "m" in the equation stands for "mass" not matter.Explain how you would create matter without energy?
When you destroy matter, you create energy. That's what a nuclear reaction is.
e=mc^2 ?
The "m" in the equation stands for "mass" not matter.
Energy just changes form without being changed/destroyed in the process.
Scientists at the Scientific Research Centre Bistra in Ptuj, Slovenia, have theorized that the
Newtonian idea of time as an absolute quantity that flows on its own, along with the idea that time is the fourth dimension of spacetime, are incorrect. They propose to replace these concepts of time with a view that corresponds more accurately to the physical world: time as a measure of the numerical order of change.
This view doesn’t mean that time does not exist, but that time has more to do with space than with the idea of an absolute time. So while 4D spacetime is usually considered to consist of three dimensions of space and one dimension of time, the researchers’ view suggests that it’s more correct to imagine spacetime as four dimensions of space. In other words, as they say, the Universe is “timeless.”
In two recent papers in Physics Essays, Amrit Sorli, Davide Fiscaletti, and Dusan Klinar, begins by explaining how we usually assume that time is an absolute physical quantity that plays the role of the independent variable (time, t, is often the x-axis on graphs that show the evolution of a physical system). But, as they note, we never really measure t. What we do measure is an object’s frequency and speed. But, by itself, t has only a mathematical value, and no primary physical existence.
“Minkowski space is not 3D + T, it is 4D,” the scientists write in their most recent paper. “The point of view which considers time to be a physical entity in which material changes occur is here replaced with a more convenient view of time being merely the numerical order of material change. This view corresponds better to the physical world and has more explanatory power in describing immediate physical phenomena: gravity, electrostatic interaction, information transfer by EPR experiment are physical phenomena carried directly by the space in which physical phenomena occur.”
“The idea of time being the fourth dimension of space did not bring much progress in physics and is in contradiction with the formalism of special relativity,” he said. “We are now developing a formalism of 3D quantum space based on Planck's work. It seems that the Universe is 3D from the macro to the micro level to the Planck volume, which per formalism is 3D. In this 3D space there is no ‘length contraction,’ there is no ‘time dilation.’ What really exists is that the velocity of material change is ‘relative’ in the Einstein sense.”
The researchers give an example of this concept of time by imagining a photon that is moving between two points in space. The distance between these two points is composed of Planck distances, each of which is the smallest distance that the photon can move. (The fundamental unit of this motion is Planck time.) When the photon moves a Planck distance, it is moving exclusively in space and not in absolute time, the researchers explain. The photon can be thought of as moving from point 1 to point 2, and its position at point 1 is “before” its position at point 2 in the sense that the number 1 comes before the number 2 in the numerical order. Numerical order is not equivalent to temporal order, i.e., the number 1 does not exist before the number 2 in time, only numerically.
Without using time as the fourth dimension of spacetime, the physical world can be described more accurately. As physicist Enrico Prati noted in a recent study, Hamiltonian dynamics (equations in classical mechanics) is robustly well-defined without the concept of absolute time.
Other scientists have pointed out that the mathematical model of spacetime does not correspond to physical reality, and propose that a timeless “state space” provides a more accurate framework. The scientists also investigated the falsifiability of the two notions of time.
The concept of time as the fourth dimension of space -- as a fundamental physical entity in which an experiment occurs -- can be falsified by an experiment in which time does not exist, according to the scientists.
An example of an experiment in which time is not present as a fundamental entity is the Coulomb experiment; mathematically, this experiment takes place only in space. On the other hand, in the concept of time as a numerical order of change taking place in space, space is the fundamental physical entity in which a given experiment occurs. Although this concept could be falsified by an experiment in which time (measured by clocks) is not the numerical order of material change, such an experiment is not yet known.
“Newton theory on absolute time is not falsifiable; you cannot prove it or disprove it -- you have to believe in it,” Sorli said. “The theory of time as the fourth dimension of space is falsifiable and in our last article we prove there are strong indications that it might be wrong. On the basis of experimental data, time is what we measure with clocks: with clocks we measure the numerical order of material change, i.e., motion in space.”
In addition to providing a more accurate description of the nature of physical reality, the concept of time as a numerical order of change can also resolve Zeno’s paradox of Achilles and the Tortoise. In this paradox, the faster Achilles gives the Tortoise a head start in the race. But although Achilles can run 10 times faster than the Tortoise, he can never surpass the Tortoise because, for every distance unit that Achilles runs, the Tortoise also runs 1/10 that distance. So whenever Achilles reaches a point where the Tortoise has been, the Tortoise has also moved slightly ahead. Although the conclusion that Achilles can never surpass the Tortoise is obviously false, there are many different proposed explanations for why the argument is flawed.
The paradox can be resolved by redefining velocity, so that the velocity of both runners is derived from the numerical order of their motion, rather than their displacement and direction in time. From this perspective, Achilles and the Tortoise move through space only, and Achilles can surpass Tortoise in space, though not in absolute time.
Some recent studies have challenged the theory that the brain represents time with an internal “clock” that emits neural ticks (the “pacemaker-accumulator” model) and suggest that the brain represents time in a spatially distributed way, by detecting the activation of different neural populations. Although we perceive events as occurring in the past, present, or future, these concepts may just be part of a psychological frame in which we experience material changes in space.
One can claim that quantum mechanics demonstrates that, at the quantum level, determinism is false and some form of indeterminism is true and this does not imply that it is random. In fact, at best one can claim quantum mechanics is indeterministic and NOT random in any ontologically interesting manner.
