Does a singularity contain mass?? if yes then according to big bang , our universe sprang into existence as “singularity” around 13.7 billion years ago. it means there was already a mass centered in zero volume.
and only a black-hole has singularity it means at the time of big bang there was a black hole in which explosion occurred.
please guide me and give me ans.
The word singularity means
“the state, fact, quality, or condition of being singular.”
“a point at which a function takes an infinite value, especially in space–time when matter is infinitely dense, such as at the centre of a black hole.”
” a point at which the derivative of a given function of a complex variable does not exist but every neighborhood of which contains points for which the derivative does exist”
Evidently, singularity refers to a unique situation, in big bang whatever state of affairs triggered contributes to the singularity.
“In universal law of gravitaion what is the word “attraction” actually refers to?
I am already on the earth surface and attached to it.Then what is the meaning that earth still attacting me accounts for.
Does that mean earth want me to attarct me towards its center point (ie.., into the inner core of the earth’s interior).
Please answer I am puzzled and worried about my analysis.
Explain with reasons…”
Asked Gopi Krishna
Yes, Earth continues to attract you until you reach its centre.
Every body attracts all other objects towards its centre, not to its surface!
First, I am a physics ‘hobbyist’; I have only rudimentary (read college classes) in physics and I absolutely recognize that I know very little about the subject except what I have studied and can find online. However, I have a theory that the flow of time causes space in much the same way that the flow of electricity causes magnetism (the ‘right hand thumb rule’, for example). This would explain the supposed curvature of space since it would flow in a circular motion nn degrees against the flow of time. This idea could explain, in a way, the faster-than-light expansion of space nanoseconds after ‘The Big Bang’ since it wasn’t space that exploded but rather time that exploded meaning time ‘flowed faster’ immediately after the big bang causing a massive, near instantaneous expansion of space at that time. (As you can see, I have far too much ‘time’ on my hands…) The problem I have – and hope someone can answer – is that I can think of no way to prove or disprove this experimentally; not so much my ancillary thoughts of time and the big bang but rather if time causes space, how can this be disproved or proved experimentally?
Asked Kenneth R. Guilstorf
The latest thinking about black holes is that they may not collapse into a singularity at all, but may actually explode back with a “big bounce” once the diameter of the black hole reaches the Planck Scale or maximally compact state and once the “big bounce” diameter expands to that of the event horizon, it would release all of the information that till then had been trapped inside the black hole, back into the universe.
My question is this, if in fact the “big bang” that led to the creation of our current universe was the result of the “big bounce” associated with the collapse of a prior universe, is there any measure of entropy that could detect this. In other words would any measure of entropy differ between the universe caused by “big bounce” n and the universe caused by “big bounce” n+k?
John Egenolf Asked
The question is left for the visitors to answer
Was every event created at the moment of the big bang by the position of every particle at that moment? Every action is based on the action of the moment before and must obey the laws and forces of physics therefor suggesting every element, compound, and even human thought were predetermined by the exact position of particles/energy at the begining of time.
