Graduate Start from Nothing: An Exploration of Pre BB Thinking
Pre Big Bang A previous writer stated why can't it be a zero-sum game? vacuum flux can "create" a particle pair out of "nothing". perhaps the universe is just an extremely large-scale version of this same concept. This begs a few questions 1. If the universe was created out of nothing... -

Alternative idea on expanding universe
That would mean that galaxies that are a very long way away would all be fully formed not undergoing expansion ? I am sure that if you reverse the meaning of all the words then you could reverse the outcome but if not you will find mismatches in observation related to the size/age of objects... -

Undergrad Black holes created the big bang?
Re your question would it be possible for the black hole to tear a hole in time space and deposit (via white hole) all the matter in an earlier time of the universe. The answer is no - time moves forward only the past is gone the future is to come. Cosmology has many odd features but... -

Graduate Is There a Universal Point Where All Moments in Time Exist Simultaneously?
Re your question Would it be safe to assume that there is and always will be a point of reference in this univerese where we will all be alive, dead, and yet to be born here on earth? No it would not - time proceeds forward. The point of reference you search for is here and now. The past is... -

Graduate Escaping the Impending Heat Death of the Universe: A Possibility or a Fantasy?
It is only my working assumption but I propose that it is not possible to avoid the big crunch. It is not possible to cross the boundary of the speed of light. You can go faster or slower but not pass through it. A universe can only be created outside our universe otherwise it would be able to... -

Undergrad Dark Matter & Universe Expansion: A Newbie Question
dark matter is not supposed by all or necessary Not everybody believes in dark matter as a concrete object. If we suppose that the universe is expanding at twice the speed of light it would have 8 times the expected volume which is approimately the ratio for actual to dark matter. The... -

Graduate Does the Universe Rotate and Does it Have an Axis?
I would propose that the universe is no rotating for the following reason. If you have a laser fired at you it does not matter whether you are stationary or moving closer or further from the laser the light will strike you at the same time. The same effect means that everywhere appears to be... -

Undergrad Is Our Universe Infinite or Spherical?
The universe is a sphere In answer to the question I propose that the universe is a type of sphere - although this is not necessarily a helpful way to look at it. The problem relates to the properties of light. If we look at the case where someone fires a bullet if we see the flash of the...
