Is there an edge of the universe?, page 1

The universe begins with a cataclysm that generates space and time, as well as all the matter and energy the universe will ever hold. For an incomprehensibly small fraction of a second, the universe is an infinitely dense, hot fireball. Energy that can suddenly push out the fabric of space. On a rare occasion, a runaway process called Inflation can cause a vast expansion of space filled with this energy. The inflationary expansion is stopped only when this energy is transformed into matter and energy as we know it. After inflation, one millionth of a second after the Big Bang, the universe continues to expand but not nearly so quickly. As it expands, it becomes less dense and cools. The most basic forces in nature become distinct: first gravity, then the strong force, which holds nuclei of atoms together, followed by the weak and electromagnetic forces. By the first second, the universe is made up of fundamental particles and energy: quarks, electrons, photons, neutrinos and less familiar types. These particles smash together to form protons and neutrons.
Protons and neutrons come together to form the nuclei of simple elements: hydrogen, helium and lithium. It will take another 300,000 years for electrons to be captured into orbits around these nuclei to form stable atoms.
The first major era in the history of the universe is one in which most of the energy is in the form of radiation -- different wavelengths of light, X rays, radio waves and ultraviolet rays. This energy is the remnant of the primordial fireball, and as the universe expands, the waves of radiation are stretched and diluted until today, they make up the faint glow of microwaves which bathe the entire universe.

Astronomers assume that the universe will gradually wither away, provided it keeps on expanding and does not recollapse under the pull of its own gravity. During the Stelliferous Era, from 10,000 years to 100 trillion years after the Big Bang, most of the energy generated by the universe is in the form of stars burning hydrogen and other elements in their cores.
The Degenerate Era
In 100 Trillion Years in the Future
This era extends to Ten Trillion Trillion Trillion years after the Big Bang. Most of the mass that we can currently see in the universe is locked up in degenerate stars, those that have blown up and collapsed into black holes and neutron stars, or have withered into white dwarfs. Energy in this era is generated through proton decay and particle annihilation.
The Black Hole Era
10 to the 100th power Years in the Future
Ten Thousand Trillion Trillion Trillion Trillion Trillion Trillion Trillion Trillion years after the Big Bang. After the epoch of proton decay, the only stellar-like objects remaining are black holes of widely disparate masses, which are actively evaporating during this era. and 10 times more At this late time, protons have decayed and black holes have evaporated.Only the waste products from these processes remain: mostly photons of colossal wavelength, neutrinos, electrons, and positrons. For all intents and purposes, the universe as we know it has dissipated.
So in short the universe will continue to grow forever. but what is intresting to me is what caused the big bang. a tiny speck of ??? just takeing up a tiny speck of emptyness in an infinite amount of nothing... yet something caused it to become unstable and expand into what we know as our universe..., but what caused it to become unstable and explode?
my theory is a piece of a universe similar to our own, long after its death
moves farther from its origination point, and collides with the tiny spec which all our own universe evolved. the collision could be a photon,neutriono, electron,or positron
this has probably been going on forever and will continue forever.
which makes you wonder. are we actually insignificant, i personally think so.
even if we get all the technology that could ever be created, we still could not find out what it all means..we could never see the big picture due to the fact we are infinitly small in the outer universes eyes. its so enormus we could never see the end to an endless outer universe...so whats the point, the point is humans have to have something to make them feel like there special, when in fact we are not If the timeline of the universe was a 100 year calander we would have been alive for 1 millionth of a second in that 100 year calander, and at the rate humanity is headed, we will have existed 1.000005 millionths of a second before humanity is wiped out
The univeres will not even know we existed....thats what we are
