We are used to thinking about the past as something stable and immutable, and to the future as something that’s somehow fluid and indefinite. 
That’s how it really is?
According to the theory of relativity, past present and future can’t be separated and split in a precise way and absolute, and this has some consequences on our interpretation of past, present and future.
Indeed, according to einstein, the future is real and fixed as much as the present and the past. 

When we think about space, we don’t have any problem visualizing it as something that exists everywhere in the same way. 
We say that something is “here” in this point of space and that another one is “there” in another point, but both things are equally real.
For what concerns time, we think about it in a completely different way. 
Everything which we think is real is something that is existing NOW.

    "Every point in time already exists." This statement is wrong. "Already" assumes a flow of time in the way we experience it. There is no "already" in a block spacetime because "already" assumes a past where the events were decided. If past, present and future are all a part of extant time axis, there is no "already," since the past isn't any more deteminative than the present or future.

    Quantum physics tells us that God really does play at dice.To use the famous thought experiment, Schrodinger cat isn't determined to be alive or dead until the point in time when the box is opened. Then the possibilities collapse into a dead or alive cat. That point along the time axis is when the decision is made, and at no other point along that axis. The fact that someone can observe the outcome before someone else opens the box doesn't mean that the outcome was decided at any point before that point along the either person's time axis.

    The fact that an observer who can see the whole axis of time knows that you decided to become an astrophysicist rather than a janitor does not mean that you didn't make the decision to become an astrophysicist. It just means that someone from a different reference frame knows what that decision will be, but that doesn't mean that you didn't still make the decision.

    So no, the block universe doesn't support predeterminism because in a block universe, there is no "pre." The "pre," like, "already," is just a figment of our time-as-a-flow addled minds.

    This is an invitation to see a theory where light is both a wave and a particle, with a probabilistic ∆×∆pᵪ≥h/4π, future continuously unfolding in relation to the electron probability cloud of atoms and the wavelength of light. In this theory, the wave-particle duality of light and matter (electrons) creates a blank canvas that we (atoms) can interact with forming a future relative to the energy and momentum of our actions. This interaction is represented by a constant of action in space and time, mathematically denoted as the Planck constant h/2π. This concept is supported by the fact that light photon energy ∆E=hf is continuous exchange into the kinetic energy Eₖ=½mv² of matter, in the form of electrons.

    In this theory, the atoms are standing waves in time. The spontaneous absorption and emission of spherical 4πr² light waves forms the characteristics of three-dimensional space with the passage of time, our every changing world. We have an uncertain ∆×∆pᵪ≥h/4π probabilistic future unfolding upon the curvature of the wave front, quanta by quanta moment by moment with each new light photon ∆E=hf electron oscillation. The uncertainty of everyday life can be seen mathematically as Heisenberg’s Uncertainty Principle between position and momentum ∆×∆pᵪ≥h/4π and energy and time ∆E ∆t ≥ h/2π.

    Galilean Relativity is the correct theory of Relativity, where time is absolute, only the present exists, the past is gone, and the future is yet to be. Relativity is based on 2 premises, the 1st is Galilean Relativity, where physics is the same in all inertial reference frames, and no experiment can be done to determine if an inertial observer is moving. And the 2nd premise is that the speed of light is the same for all inertial observers. I argue that the 2nd premise is a part of the 1st premise, which says physics is the same in all inertial reference frames, and no experiment can be done to determine if an inertial observer (earth) is moving. The Michelson Morley experiment attempted to measure the speed of the earth, by comparing the speed of light in 2 orthogonal directions. The famous null result then meant that the speed of light is the same in all directions for all inertial observers. So the speed of light must be a constant for all inertial observers, in order that for the Michelson Morley experiment to not be able to detect the velocity of the earth.

    So if Relativity's 2 premises are just Galilean Relativity, then you can not get different transformations than those of Galilean Relativity (Galilean transformations), and if you do get the Lorentz transformations using Einsteins arguments, then they are wrong, because this is a logical fallacy, since according to logic, a series of premises can not lead to different conclusions. Any theory based on a fallacy is wrong, no matter how many people of experiments claim it is true.

    Relativity is just an optical illusion, and because all of modern physics is based on Relativity, modern physics is fundamentally wrong and needs to be rethought. Relativity has a simple built in logical fallacy, and no theory based on a logical fallacy can be true, no matter how many experiments seem to prove it, or how many people say it is true. Below is a very simple logical argument highlighting the logical fallacy, using the same terminology Einstein used to derive Relativity.

    According to Relativity, observers on a moving train and on a stationary train platform will disagree on the size of the ""Train"" and the passage of time on the ""Train"". This is a complete logical contradiction if the size and the passage of time of the train are real. If the size of the train is real, then the ""Train"" can not be both contracted and not contracted. The same goes for the observed passage of time on the ""Train"". If these effects are observed, then the only possible conclusion is that it is an optical illusion. Things that are real must appear to be same from all frames of reference. If not, then by definition it is an illusion.

    Again the argument is very simple and it is the argument Einstein used to derive Relativity, and no acceleration is used in the argument. A train with length (L) traveling at constant velocity (v) relative a stationary observer on a station platform. According to Relativity, the stationary observer will see the train contracted (L/r, where r is the Relativistic gamma), whereas an observer on the train will see it not contracted (L). So the train is both contracted (L/r) and not contracted (L) depending on the observer. This is a complete contradiction (L not equal L/r) and can not be true if length is real. The same argument applies to passage of time on the Train, where both observers will disagree on the passage of time. If time is real, it can not be both dilated and not dilated (T not equal rT). If space and time are observed to be both large and small simultaneously for one inertial reference frame, such as the ""Train"", then it must be an optical illusion.

    This argument is only the tip of the iceberg. There is much more evidence including both theoretical and experimental, so please keep reading. Hi my name is Dr William Walker and I am a PhD physicist and have been investigating this topic for 30 years. It has been known since the late 1700s by Simone LaPlace that nearfield Gravity is instantaneous by analyzing the stability of the orbits of the planets about the sun. This is actually predicted by General Relativity by analyzing the propagating fields generated by an oscillating mass. In addition, General Relativity predicts that in the farfield Gravity propagates at the speed of light. The farfield speed of gravity was recently confirmed by LIGO.

    Recently it has been shown that light behaves in the same way by using Maxwell's equations to analyze the propagating fields generated my an oscillating charge. For more information search: William Walker Superluminal. This was experimentally confirmed by measuring radio waves propagating between 2 antennas and separating the antennas from the nearfield to the farfield, which occurs about 1 wavelength from the source. This behavior of gravity and light occurs not only for the phase and group speed, but also the information speed. This instantaneous nature of light and gravity near the source has been kept from the public and is not commonly known. The reason is that it shows that both Special Relativity and General Relativity are wrong! It can be easily shown that Instantaneous nearfield light yields Galilean Relativity and farfield light yields Einstein Relativity. This is because in the nearfield, gamma=1since c= infinity, and in the farfield, gamma= the Relativistic gamma since c= farfield speed of light. Since time and space are real, they can not depend on the frequency of light used. This is because c=wavelength x frequency, and 1 wavelength = c/frequency defines the nearfield from the farfield. Consequently Relativity is an optical illusion. Objects moving near the speed of light appear to contract in length and time appears to slow down, but it is just what you see using farfield light. Using nearfield light you will see that the object has not contracted and time has not changed. For more information: Search William Walker Relativity.

    Since General Relativity is based on Special Relativity, General Relativity must also be an optical illusion. Spacetime is flat and gravity must be a propagating field. Researchers have shown that in the weak field limit, which is what we only observe, General Relativity reduces to Gravitoelectromagnetism, which shows gravity can be modeled as 4 Maxwell equations similar in form to those for electromagnetic fields, yielding Electric and Magnetic components of gravity. This theory explains all gravitational effects as well as the instantaneous nearfield and speed of light farfield propagating fields. So gravity is a propagating field that can finally be quantized enabling the unification of gravity and quantum mechanics.

    The current interpretation of quantum mechanics makes no sense, involving particles that are not real until measured, and in a fuzzy superposition of states. On the other hand, the Pilot Wave interpretation of Quantum Mechanics makes makes much more sense, which says particles are always real with real positions and velocities. The particles also interact with an energetic quantum field that permeates all of space, forming a pilot wave that guides the particle. This simpler deterministic explanation explains all known quantum phenomena. The only problem is that the Pilot Wave is known to interact instantaneously with all other particles, and this is completely incompatible with Relativity, but is compatible with Galilean Relativity. But because of the evidence presented here, this is no longer a problem, and elevates the Pilot Interpretation to our best explanation of Quantum Mechanics.

    "Every point in time exists just like every point in space"
    OK. but space is contantly expanding, so why couldn't the same thing hold true for the fourth dimension (i.e., time)? Couldn't that expansion be what we experience as the flowing of time?
