    Can it be knowable to entities living in 2D shadowland to know that they are simply a projection coming from a 3D reality?

    A simple yes or no would be ideal.

    Your question has no basis in reality and is therefore irrelevant.

    The Ideal Gas Law handles this adequately enough. I'm not sure why a new hypothesis is needed.

    The sun's core will heat up as it runs through its hydrogen, then helium fuel more quickly. It's mass and therefore its gravity will not change. The increase in temperature will lead to an expansion of volume.

    Fify.

    This really becomes more of a philosophical discussion than a purely scientific topic as there is no way to test any hypothesis such as M-theory or string theory. Personally, I find string theory to be most fascinating and incredibly profound. An idea that I've had about why some of the strings would be closed anynd others would be open is that all strings are closed, however we would only be able to see (detect) the vibrations they resonate through our three dimensional spacetime. In actuality, they would likely close and form their loop in a higher spatial dimension above our own.

    I woudnt say it has no basis in reality. A shadow is a 2D slice of a 3D object projected upon it. With this knowledge, we can conceivably identify any object if we can capture enough images of the projected 2D slices. To carry this further, an object with 4 spatial dimensions would project 3D shadows upon our 3D plane. As the 4D object moves along any axis through its higher dimensions, we would observe the shadow slices changing. I'm pretty sure this is part of the holographic conjecture hypothesis.

    Anyone else get the feeling like we are on step 3 of human evolution out of like a 1000 steps? And also feel a little pissed off we will not be part of the telekinesis steps, etc?

    1. Don't $#@! outside
    2. Invent computers


    556. Telekinesis

    1000. Pure energy

    I get the feeling that our existence will change very rapidly and in some ways catastrophically.

    Telekinesis and stuff like that which today seem like complete science fiction, won't seem that way even 10 years from now. In 2027 we won't call it telekinesis, but in many ways whatever we call it will, to a 2017 observer, be indistinguishable from telekinesis.

    Neonmoon, I think I'm pickin' up what you're layin' down. I don't think each "step" would happen one at a time, but would instead be groups and some "steps" may be higher up than others along the way.

    With research currently underway, mapping the human brain with electrodes and the eventual advent of a device to detect and interpret signals directly from the brain will facilitate exactly what Grammer is talking about, at least in my estimation.

    From Phys.org this month:

    No Big Bang? Quantum equation predicts universe has no beginning

    (Phys.org) —The universe may have existed forever, according to a new model that applies quantum correction terms to complement Einstein's theory of general relativity. The model may also account for dark matter and dark energy, resolving multiple problems at once.

    The widely accepted age of the universe, as estimated by general relativity, is 13.8 billion years. In the beginning, everything in existence is thought to have occupied a single infinitely dense point, or singularity. Only after this point began to expand in a "Big Bang" did the universe officially begin.

    Although the Big Bang singularity arises directly and unavoidably from the mathematics of general relativity, some scientists see it as problematic because the math can explain only what happened immediately after—not at or before—the singularity.

    "The Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there," Ahmed Farag Ali at Benha University and the Zewail City of Science and Technology, both in Egypt, told Phys.org.

    Ali and coauthor Saurya Das at the University of Lethbridge in Alberta, Canada, have shown in a paper published in Physics Letters B that the Big Bang singularity can be resolved by their new model in which the universe has no beginning and no end.

    Old ideas revisited
    The physicists emphasize that their quantum correction terms are not applied ad hoc in an attempt to specifically eliminate the Big Bang singularity. Their work is based on ideas by the theoretical physicist David Bohm, who is also known for his contributions to the philosophy of physics. Starting in the 1950s, Bohm explored replacing classical geodesics (the shortest path between two points on a curved surface) with quantum trajectories.

    In their paper, Ali and Das applied these Bohmian trajectories to an equation developed in the 1950s by physicist Amal Kumar Raychaudhuri at Presidency University in Kolkata, India. Raychaudhuri was also Das's teacher when he was an undergraduate student of that institution in the '90s.

    Using the quantum-corrected Raychaudhuri equation, Ali and Das derived quantum-corrected Friedmann equations, which describe the expansion and evolution of universe (including the Big Bang) within the context of general relativity. Although it's not a true theory of quantum gravity, the model does contain elements from both quantum theory and general relativity. Ali and Das also expect their results to hold even if and when a full theory of quantum gravity is formulated.

    No singularities nor dark stuff
    In addition to not predicting a Big Bang singularity, the new model does not predict a "big crunch" singularity, either. In general relativity, one possible fate of the universe is that it starts to shrink until it collapses in on itself in a big crunch and becomes an infinitely dense point once again.
    Ali and Das explain in their paper that their model avoids singularities because of a key difference between classical geodesics and Bohmian trajectories. Classical geodesics eventually cross each other, and the points at which they converge are singularities. In contrast, Bohmian trajectories never cross each other, so singularities do not appear in the equations.

    In cosmological terms, the scientists explain that the quantum corrections can be thought of as a cosmological constant term (without the need for dark energy) and a radiation term. These terms keep the universe at a finite size, and therefore give it an infinite age. The terms also make predictions that agree closely with current observations of the cosmological constant and density of the universe.

    New gravity particle
    In physical terms, the model describes the universe as being filled with a quantum fluid. The scientists propose that this fluid might be composed of gravitons—hypothetical massless particles that mediate the force of gravity. If they exist, gravitons are thought to play a key role in a theory of quantum gravity.
    In a related paper, Das and another collaborator, Rajat Bhaduri of McMaster University, Canada, have lent further credence to this model. They show that gravitons can form a Bose-Einstein condensate (named after Einstein and another Indian physicist, Satyendranath Bose) at temperatures that were present in the universe at all epochs.

    Motivated by the model's potential to resolve the Big Bang singularity and account for dark matter and dark energy, the physicists plan to analyze their model more rigorously in the future. Their future work includes redoing their study while taking into account small inhomogeneous and anisotropic perturbations, but they do not expect small perturbations to significantly affect the results.
    "It is satisfying to note that such straightforward corrections can potentially resolve so many issues at once," Das said.

    So... I wonder what their model says about singularities at the heart of black holes. The laws of physics break down there as well.

    Singularities occur and are more a function of the mathematics than anything else. Stand on the north pole and tell me which way is north.

    Do they even make a falsifiable prediction?
