    An infinite number of infinitely diminishing sub-universes?

    We all know that there's one universe, which, while reason suggests is infinite outwardly, may or may not be. But how about going inward? Reason suggests that from each point of our universe, there would need to be smaller and smaller things, (which, perhaps, may not be "particles") and, at...

    Expansion - Inflation - in an infinite Universe

    Inflation - expansion. Need an explanation - Last piece to explain logically past the breakdown of the math. My thinking is once I get the link clearly demonstrated that it Cycles BB - Gravity - BB - Gravity on larger scales then Math can be applied to whats we are all missing...

    Infinite Universe Idea

    Some thinking on an infinite universe with dark matter, dark energy and an increase in expansion which also might explain why 2 galaxies have no dark matter. A simple out of the box thought experiment using logic rather than math to fill in the banks of going from a universe dominated by...

    How does Thermodynamics relate to Cosmology?

    Hi, I get a lot of classical thermo e.g. concepts of pressure, temperature and entropy in a closed control volume, but I don't exactly get how it's applied to big picture things such as galaxies, nebula, black hole and the beginning of the universe. I really can't conceptualise anything that...

    Where does dark matter and dark energy exist in the universe?

    Where does dark matter and dark energy exist in the universe? Moving objects will cause dark matter and dark energy to move along with it. Dark matter and dark energy are arranged to form circles around the object. These circles continuously develop a radius of a geometric progression (scale...

    Question on Matter, Energy & The Expanding Universe

    Hi - I'm an English major, not a physicist - never taken a physics class in my life, but I've been wondering about something, and hope for some help. Here it is. Is it fair to say the universe is a fixed system? By that I mean that all the matter that exists in the universe is all...

    Knowledge of Everything

    Hi Guys, I wrote research (actually just a bit completed it, since it is based on enormous previous scientific research) which I call 'Knowledge of Everything', what means that it represents complete basic physical knowledge about the Universe, which was just released to public several days...

    universe death

    Whether we regard the universe as a expanding sphere or the surface of an expanding balloon, as, starting with the beginning of time, all spherical stellar masses in the universe emit photons (electromagnetic energy) in every direction, more than half of all photons are being irreversibly sent...

    what was energy of universe at big bang?

    I got couple questions regarding the following YouTube video: MTUsOWtxKKA 1. When Universe was at size of one billionth of a proton, what was the energy of the universe at that point? 2. It says during the inflation expansion of universe, the space mass density of universe stayed...

    Gravitation in the Universe

    Hi, I'm happy to have found this forum :) We created some animations on the workings of gravitation and centrifugal forces in the Universe. Perhaps, someone find it useful or want to give feedback :) SfFSkGUm3nM Best wishes, Rolf

    Can the shape of universe be anything like this...?

    Hi, Is it possible that the shape of the universe is anything like this picture? postimg.org/image/j3o5qb4p9/ (sort of duoble spiral) I just want to know how likely or not it is, or if it's ridiculous or possible? Thanks!

    Predicted Heat Death of the Universe

    Predicted Heat Death of the Universe In his thought provoking documentary “Wonder of the universe” (https://www.youtube.com/watch?v=Uu-tJmRxcVw ) Professor Brian Cox explains the thinking behind current predictions for the “Heat death of the universe”. He explains the predictions through the...

    Which transfers more heat as a whole in the universe?

    Which transfers more heat as a whole in the universe? Conduction vs radiation The most obvious guess is radiation due to stars. Conduction seems to be considered negligible in stars but I've only read that in the context of energy transport to the surface and not necessarily just back and...

    Is the Universe Random?

    Does Physics describe a fixed deterministic universe? At the quantum level there only seems to be a probabilistic description of behaviours, and this appears to be the actual basic essence of existence at this level. At the macroscopic level things seem to average out to give a completely...

    Dissection of the universe

    Can we assume that an entity which can have more than one "form" must be composed of more primitive entities?

    An alternative hypothesis to explain 'the expanding universe'...

    An alternative hypothesis to explain the observation of 'the expanding universe' following Hubble's Law First of all, I want to say that this is a hypothesis of mine. It's a result of long thinking, but that's not an argument at all of course. Please be not too hostile, when you destroy it...

    The Unobservable Universe

    If we (Hubble) can see galaxies I think anout 500 million years after the Big Bang, and if we also can detect the radiation afterglow of the Big Bang (Cosmic backgound radiation) which is the first light of the Universe some 300 billion years after the BB, then what is the unobservable part of...

    Primary constituent entities of the universe.

    I propose that the primary constituent entities of our universe are toroidal fields.

    The existence of the universe physics

    When I count the time before and now, it seems like we can figure out the watch forever and live. But as the result, cannot remember the memory before the time as there is eschatology that cut the flow of the time. No logical meaning for the universe as big bang and evolution as can be...
