BUT! One second after the Big Bang, the universe was filled with neutrons, protons, electrons, anti-electrons, photons and neutrinos. The combination of this knowledge leads us to uncove… Not only does the model explain the origin of all known matter, the laws of physics, and the large scale structure of the Universe, it also accounts for the expansion of the Universe and a broad range of other phenomena. Critical universe: the density of the universe is equal to the critical density. Nobody knows with accuracy how the first religions evolved. In other words, the universe has no center; everythi… Meanwhile, the High-Energy background is believed to due to a number of sources, not the least of which is supernovae, matter/anti-matter interaction and interstellar gas. ???? How was our Universe conceived in a massive explosion, what proof is there of this, and what does the theory say about the long-term projections for our Universe? They are manifestly very stable structures, and current theory says they are very old. Most cosmological models suggest that the Universe at this point was filled homogeneously with a high-energy density, and that the incredibly high temperatures and pressure gave rise to rapid expansion and cooling. . It's hard to keep oxygen molecules around, despite the fact that it's the third-most abundant element in the universe, forged in the superhot, superdense core of … Working backwards from the current state of the Universe, scientists have theorized that it must have originated at a single point of infinite density and finite time that began to expand. NASA’s WMAP mission webpage, Big Bang Cosmology, and its “What is the Big Bang Theory?” also gives good introductions to the big bang theory. The Universe is full of living things and non-living things with no empty spaces . Dark matter is the same, having been theorized as being necessary and likely due to the presence of mass in space we cannot be account for, and for everything we know about gravity on macro scales to work. We have many interesting articles about the Big Bang here at Universe Today. by using math that can only cope with countable and measurable Through the testing of theoretical principles, experiments involving particle accelerators and high-energy states, and astronomical studies that have observed the deep universe, scientists have constructed a timeline of events that began with the Big Bang and has led to the current state of cosmic evolution. Then, from 10-36 to 10-32 seconds after the Big Bang, the temperature of the universe was low enough (1028 K) that the forces of electromagnetism (strong force) and weak nuclear forces (weak interaction) were able to separate as well, forming two distinct forces. Galaxies are likewise, and even they can cluster like stars in a globular cluster. This means that no matter what galaxy you happen to be in, all the other galaxies are moving away from you. One difficulty is the horizon problem. the CMB, the edge of what we can see) and become invisible to us. Since the early part of the 1900s, one explanation of the origin and fate of the universe, the Big Bang theory, has dominated the discussion. Finally, the entropy of the universe would increase to the point where no organized form of energy could be extracted from it (a scenarios known as “heat death”). This will only be possible if the mass density of the Universe is greater than the critical density. I think science has become stuck in the rut of Big Bang thinking. From approximately 10-43 second and 10-36, the universe began to cross transition temperatures. New technology and social media sites are constantly changing, evolving and developing, which means the face of personal communication is also changing. In addition to providing an explanation as to the universe’s missing mass (along with Dark Matter, originally proposed in 1932 by Jan Oort), it also provided an explanation as to why the universe is still accelerating, as well as offering a resolution to Einstein’s Cosmological Constant. After these annihilations, the remaining protons, neutrons and electrons were no longer moving relativistically and the energy density of the universe was dominated by photons – and to a lesser extent, neutrinos. http://wwwmpa.mpa-garching.mpg.de/~swhite/talk/fermilab.pdf. I mean ….. seconds , minutes , hours , days , months and years are artificial . http://iiste.org/Journals/index.php/APTA/article/view/26837, Join our 836 patrons! Other explanations of dark energy, called phantom energy theories, suggest that ultimately galaxy clusters, stars, planets, atoms, nuclei, and matter itself will be torn apart by the ever-increasing expansion. It was hard to continue with the rest of the article with those two immediate errs sticking in my head. But what exactly does it mean? This is also known as heliocentric. It will have the same density, will still be expanding, and will have the same general features (galaxies, quasars, etc) that are observed today. …… infinity . Energy can never be dark as in invisible unless it is in storage as “potential energy.” Kinetic energy is a force that can indeed cause the effects attributed to “dark energy” because it is invisible too. https://books.google.ca/books?id=Q31L1Lj4XzoC&dq=%22X-ray+background%22&redir_esc=y. Thus time is endless in both directions , forwards or backwards . This so-called, "dark matter" makes up roughly 27% of the matter-energy content of the universe, while the visible pieces account for only about 5% of the total. The Big Crunch and an Oscillating universe are not part of the Big Bang model, merely possible extensions and an alternative to it. In this case, it is associated with Dark Energy, which served to accelerate the expansion of the universe and keep its large-scale structure largely uniform. As space expanded, the universe cooled and matter formed. Despite its supposed proof of the big bang, the cosmic microwave background has been a source of challenges to the standard cosmology. The details of this process depend on the amount and type of matter in the universe, with cold dark matter, warm dark matter, hot dark matter, and baryonic matter being the four suggested types. There is always something whose range can be { almost nil } to { infinity } . The 1990s also saw the rise of Dark Energy as an attempt to resolve outstanding issues in cosmology. Furthermore, these elements are observed in just the proportions (roughly 75% hydrogen, 25% helium) predicted to have been produced during the Big Bang. the universe . Image 1 The string is comparable in size to the "Great Wall" of galaxies found in the nearby Universe by Dr. John Huchra and Dr. Margaret Geller in 1989. Scientists have been studying the Earth for centuries, and we know a lot more than we once did. From this point onward, the Universe began to cool and matter coalesced and formed. The galaxies and clusters of galaxies that make up the visible universe are concentrated in a complex scaffold that surrounds a network of enormous cosmic voids. “That means that even if there have been a thousand civilizations in our own galaxy, if they live only as long as we have been around—roughly ten thousand years—then all of them are likely already extinct. Or will it one day run out of expansive force, and begin retreating inward until all matter crunches back into a tiny ball? We need to know what theory the ENTIRE background spectrum is consistent with. The number of sub-sub-particles , sub-particles , particles , atoms , planets , It is like that now . What are the characteristics of the Solar System? Some argue that the fear of destruction has been a powerful motivator for peace, but this is hardly a stable solution as can be seen with today's situation with North Korea. There are many questions associated with the creation and evolution of the major constituents of the cosmos. It is here that the fundamental forces that govern the Universe are believed to have began separating from each other. are infinite . It was like that zillion of years ago . http://www.universetoday.com/117295/new-signal-may-be-evidence-of-dark-matter-say-researchers/ quantities . In Ptolemy’s model, the Earth was at the centre of the Universe, with the Sun and planets revolving in a seriesof circular orbits moving out from the Earth. Across many fields of study, we try to understand the universe on a very large scale or on the microscopic level. Therefore there is neither the Creator (Big Bang) nor the complete end of And what will become of it, ages from now? can be part of a Steady State Universe just as exploding stars, nova, and other catastrophic events can be. And I suspect it has to do with gravitation. For example, scientists believe that about 10-11 seconds after the Big Bang, particle energies dropped considerably. This Planck period of time extends from point 0 to approximately 10-43 seconds, and is so named because it can only be measured in Planck time. I am just hoping for something better than the-little-dot-exploded-and-became-the-Universe theory (which sounds ridiculous on its face). The big bang was not an “Explosion”, and should NEVER be described as such. Eventually, the observational evidence began to favor Big Bang over Steady State. ???? The galaxies outside of our own are moving away from us, and the ones that are farthest away are moving the fastest. infinity – 3 = infinity The basics of the Big Bang theory are fairly simple. Again, I don’t have a physical theory about how the Universe began. infinity + infinity = infinity Very gradually, collisions between these black holes would result in mass accumulating into larger and larger black holes. A few minutes into the expansion, the period known as Big Bang nucleosynthesis also began. The Big Bang theorists are cherry picking the evidence. At the same time, Hubble began developing a series of distance indicators using the 100-inch (2.5 m) Hooker telescope at Mount Wilson Observatory. Gravity will eventually reverse the expansion, resulting in a "Big Crunch." From the late 60s to the 1990s, astronomers and cosmologist made an even better case for the Big Bang by resolving theoretical problems it raised. Throughout history, countless myths and scientific theories have tried to explain the universe's origins. Also known as the Planck Epoch (or Planck Era), this was the earliest known period of the Universe. 1. In order to understand how the universe has changed from its initial simple state following the Big Bang (only cooling elementary particles like protons and electrons) into the magnificent universe we see as we look at the night sky, we must understand how stars, galaxies and planets are formed. In order to understand how the universe has changed from its initial simple state following the Big Bang (only cooling elementary particles like protons and electrons) into the magnificent universe we see as we look at the night sky, we must understand how stars, galaxies and planets are formed. In the second century CE, Ptolemy, who lived in the Egyptian town of Alexandria, produced a mathematical representation based on observation of the known Solar System. or Also, it describes the singularity and “infinite density” as fact, when it clearly isn’t, especially since the singularity and infinite density both arise from an incomplete mathematical description. The reality is …… irreversible and endless series of events of living things . and their measurements can be almost zero to infinity . The eventual result of this is not currently known, but “heat death” is considered a likely end point in this scenario too. Alternatively, if the density in the universe were equal to or below the critical density, the expansion would slow down but never stop. With the acceptance of the Big Bang Theory, but prior to the observation of Dark Energy in the 1990s, cosmologists had come to agree on two scenarios as being the most likely outcomes for our Universe.
