If world began after the BIG BANG in a concentrated mass ... where did this concentrated mass come from ?

Answer 1

The early universe was filled homogeneously and isotropically with an incredibly high energy density and concomitantly huge temperatures and pressures. It expanded and cooled, going through phase transitions analogous to the condensation of steam or freezing of water as it cools, but related to elementary particles.

Approximately 10-35 seconds after the Planck epoch a phase transition caused the universe to experience exponential growth during a period called cosmic inflation. After inflation stopped, the material components of the universe were in the form of a quark-gluon plasma (also including all other particles—and perhaps experimentally produced recently as a quark-gluon liquid [3]) in which the constituent particles were all moving relativistically. As the universe continued growing in size, the temperature dropped. At a certain temperature, by an as-yet-unknown transition called baryogenesis, the quarks and gluons combined into baryons such as protons and neutrons, somehow producing the observed asymmetry between matter and antimatter. Still lower temperatures led to further symmetry breaking phase transitions that put the forces of physics and elementary particles into their present form. Later, some protons and neutrons combined to form the universe's deuterium and helium nuclei in a process called Big Bang nucleosynthesis. As the universe cooled, matter gradually stopped moving relativistically and its rest mass energy density came to gravitationally dominate that of radiation. After about 300,000 years the electrons and nuclei combined into atoms (mostly hydrogen); hence the radiation decoupled from matter and continued through space largely unimpeded. This relic radiation is the cosmic microwave background.

Over time, the slightly denser regions of the nearly uniformly distributed matter gravitationally attracted nearby matter and thus grew even denser, forming gas clouds, stars, galaxies, and the other astronomical structures observable today. The details of this process depend on the amount and type of matter in the universe. The three possible types are known as cold dark matter, hot dark matter, and baryonic matter. The best measurements available (from WMAP) show that the dominant form of matter in the universe is cold dark matter. The other two types of matter make up less than 20% of the matter in the universe.

The universe today appears to be dominated by a mysterious form of energy known as dark energy. Approximately 70% of the total energy density of today's universe is in this form. This component of the universe's composition is revealed by its property of causing the expansion of the universe to deviate from a linear velocity-distance relationship by causing spacetime to expand faster than expected at very large distances. Dark energy in its simplest formation takes the form of a cosmological constant term in Einstein's field equations of general relativity, but its composition is unknown and, more generally, the details of its equation of state and relationship with the standard model of particle physics continue to be investigated both observationally and theoretically.

All these observations are encapsulated in the ΛCDM model of cosmology, which is a mathematical model of the Big Bang with six free parameters. Mysteries appear as one looks closer to the beginning, when particle energies were higher than can yet be studied by experiment. There is no compelling physical model for the first 10-33 seconds of the universe, before the phase transition that grand unification theory predicts. At the "first instant", Einstein's theory of gravitation predicts a gravitational singularity where densities become infinite. To resolve this paradox, a theory of quantum gravitation is needed. Understanding this period of the history of the universe is one of the greatest unsolved problems in physics.

Answer 2

The theory does not attribute the earth to have come from a concentrated mass but the universe. It is further thought the concentrated masses form when stars above a certain critical size run out of fuel. They then collapse because the gravitational forces created overcome the forces between subatomic particles which give objects shape.

However there is a question whose answer scientists have failed to make me comprehend. That is if the big bang theory was true, the universe could only have started from a singularity. We are told that nothing can escape the event horizon. This is the sphere beyond which any object traveling even at the speed of light away from the center of the mass cannot escape the gravitational pull. This also implies this singularity should have had the highest possible concentration of mass. i.e. the entire mass of the universe. How did our present universe escape the greatest gravity possible?

Answer 3

The world didn't begin until several billion years after the bang. The universe's expansion to its current state is what resulted from the bang you're talking about.
That said, the answer to your question could be...we don't know....yet. We theorize that the universe was infinitesimally small at the moment of the "bang" (more of a "Whoosh" actually), and that remnants of that smallness still exist and can be "seen" when we collide the smallest of the small with each other in super colliders. The problem is that we need to generate HUGE, MASSIVE, SPECTACULARLY LARGE amounts of energy to get these particles to collide in a meaningful way to let us see the results of what the "whoosh" looked like. At this time, mankind does not possess the technology to create that kind of power.

Answer 4

Good question. My personal belief is that there had to be a creator - science tells us that you cannot get something from nothing in a naturally occurring process. There had to be an outside force; all things are examples of kinetic or active energy, and that energy must be transferred from something, if something is created.

Also interesting about the Big Bang, is that planets do not spin in the same directions. If the Big Bang happened without an external force (a creator, for example, with a higher plan), the planets would all spin in the same direction, according to the laws of physics.

Answer 5

It is quite likely that the concentrated mass (as well as time and space) that preceded the Big Bang came from repeated expansions and contractions of our universe in some form. This theory is known as the Big Bounce and combines the theory of the Big Bang with the theory of the Big Crunch.

Answer 6

The "world" didn't begin "after the BIG BANG," the universe did. And the big bang wasn't concentrated mass, it was concentrated space-time according to the best theory. Matter arose from vaccum fluctuations in space-time.

Our planet ("the world") came much later, some 10 billion years after the big bang. It took several generations of stars forming and dying, creating heavy elements in their nuclear reactions, to make the raw materials from which our solar system, our planet, and we are made.

Answer 7

The concentrated mass didn't necessarily have to come from anywhere. It's possible that it just started as a random quantum fluctuation that had a lot of energy, which, according to quantum mechanics, has to happen eventually. But then, if the energy in the fluctuation happened to exactly balance the attraction force, it wouldn't have to fluctuate back into nothing, so it could give birth to a universe.

Answer 8

That is still not answered. Scientists can only look so far into the past. Actually, research now shows that the Big Bangs was unlikely and that teh universe came about in some other way.

Answer 9

From the current theories (M Theory), ours is one of but many parallel universes ..... the "concentrated mass" resulted when two or more of these universes touched sparking a new universe (ours). This is all very over simplified but suffice to say the "real" reality of our universe is so much stranger than you might believe. I have linked a somewhat decent page below.

Answer 10

It didn't come from anywhere. It was always around. Or you could think really deeply into it. Since the universe is in the form of a mobeus strip, and is inescapable, maybe it came from all the mass in the universe collapsing into itself sometime in the distant future, and repeating the big boom for eternity.
