If microwave radiation in the universe were visible it would be bright and astonishingly uniform. How does this support the big bang theory?
The uniformity of microwave radiation in the universe, specifically the cosmic microwave background (CMB) radiation, supports the Big Bang theory by providing evidence of the hot, dense state of the early universe. The CMB is a remnant from approximately 380,000 years after the Big Bang, when the universe cooled enough for photons to travel freely. Its uniformity across the sky indicates that the universe was once in thermal equilibrium and has been expanding and cooling since that time, consistent with predictions of the Big Bang model. Thus, the uniformity and presence of this radiation serve as strong evidence for the origins and evolution of the universe as described by the Big Bang theory.
Which statements are true regarding scientific evidence supporting the big bang theory CMB radiation and a very early form of helium were discovered. The universe has structure and uniformity. Redshif?
The statements that are true regarding scientific evidence supporting the Big Bang theory include the discovery of cosmic microwave background (CMB) radiation, which is a remnant of the early universe and provides strong evidence for the Big Bang. Additionally, the observed redshift of distant galaxies supports the expansion of the universe, indicating that it was once much smaller and denser. The presence of helium in the universe, formed during the Big Bang nucleosynthesis, further corroborates this theory. Overall, the universe exhibits both large-scale structure and uniformity, consistent with predictions made by the Big Bang model.
What does it mean when someone says the universe is expanding?
Two answers from me. 1. There is more room for possibilities. 2. The big bang theory and how it all went from one little speck to the universe. The discovery channel actually had a show on this once.
How is the idea that the universe started in a big bang a logical extension from a fact?
The idea that the universe started with a Big Bang is a logical extension from the observation that galaxies are moving away from each other, a phenomenon known as redshift. This expansion suggests that the universe was once concentrated in a very small, hot, and dense state. Additionally, the discovery of cosmic microwave background radiation provides further evidence of the conditions present shortly after the universe's inception. Together, these facts support the Big Bang theory as a coherent explanation for the origins and evolution of the universe.
What is the Big Bang Theory and what does it attempt to explain?
The big Bang Theory explains that the universe started as nothingness and the nothingness expanded somehow and made a big bang.that is how all of the galaxies and worlds were made. x x x xThe light distance galaxies shows that clusters of galaxies are all moving away from each other. The universe is big and getting bigger. space itself is expanding.Imagine filming this expanding universe. If you ran the film backwards. You could see how it all began. the universe once had no size at all. It burst into existence from nothing. It is incredibly hot. This is called big bang theory.:)the big bang theory explains how the universe was createdThe Big Bang is one of the theories on how the Earth was formed.

Does oscillation of universe occur in your universe only or there are more universes?
This is "The theory" which may also explain the acceleration, that is taking place in the universe. Our universe is surrounded by some 4 such universes, probably four pre big bang masses. In turn the four pre big bang masses are surrounded by four universes. Those universes are surrounded again four pre big bang masses. So one universe is surrounded by four pre big bang masses and one pre big bang mass is surrounded by four universes. You can find the structure of carbon atoms in case of diamond to imagine the same. So your universe is getting acceleration due to gravitational forces of the four pre big bang masses and other universes. So there is probably nothing like 'Dark energy", which "Push" the universe. But there are probably four "Pre big bang masses" and other universes, which are "Pulling" your universe from the "Out side" to give acceleration to your universe. It may take another billions of years, for your universe to "Fall", on those pre big bang masses. Once your universe "Fall" on such pre big bang masses, that will initiate "Big bang" there in those pre big bang masses. This theory also explains to why the acceleration in expansion of the universe did not start from the starting of the big bang. The big bang started at the point, where the gravitational force of the outer universes was zero, like Lagrangian points. Once your universe started to expand, it drifted more and more from this zero gravity point. That gave an opportunity to outer pre big bang masses and universes to pull your universe apart, giving it an acceleration.

What theories about the creation of the universe have been accepted in the past?
Until the second half of the twentieth century, the Steady State Theory predominated. This holds that the universe has always existed, very much as it does now. Stars may grow old and cold, but new stars are formed out of the abundant interstellar matter. So, the universe will continue to exist as it does now, for many billions of years. While the Steady State Theory may still have some adherents, the predominant theory among scientists is called the Big Bang Theory. This holds that, about 13.7 billion years ago, an infinitessimally small point exploded to produce the entire universe. Once again, stars may grow old and cold, and new stars form out of the abundant interstellar matter, but the difficulty of infinite existence does not apply. There are at least two, somewhat compatible, hypotheses as to what formed the infinitessimally small point and triggered the Big Bang. Some scientists believe that the process that triggered the Big Bang could have occurred more than once. If so, there could be many universes, in what has been termed a multiverse. However, we will probably never become physically aware of any of the other universes.
What is logical explanation for acceleration in expansion rate of the universe?
* The Doppler Effect provides evidence that the universe is expanding. However, the redshift observed may be due to light climbing out of a gravity well (a star). Bigger stars can been seen from further away. Bigger stars have a greater redshift (due to size of the greater gravity well). So maybe the Universe doesn't expand as we were lead to believe? Or maybe it does.
Will the Big Bang happen again?
Good question by the way. Well, since the universe is infinite and if the big bang happened just once in infinity, then it has the ability to happen an infinite number of times. Which is why I dont suscribe to the theory. == Possibly. Right after the Big Crunch.
Why do scientists believe that the universe began with an explosion?
Scientists believe in the Big Bang theory because it is supported by evidence such as the cosmic microwave background radiation and the observed expansion of the universe. These observations suggest that the universe was once in a hot, dense state and has been expanding since its beginning.
Why does nothing started to form into something?
if you mean "why did the big bang occur?" then here goes: there are many popular ideas as to how the big bang theory started. 1: God that's right, God. The original idea for the big bang theory was composed by a christian priest who reasoned that for the universe to spontanteously create itself it had to be directed by a higher power (ie. god). 2: The existence of attracting forces outside of the universe according to one theory, the point that once was the universe started expanding when some clouds of energy exerted a pulling force on the point. I do not know much about this theory, but from logical deduction it leads to the belief in multiple universes, something larger than the universe and matter, and several other advanced concepts. 3: it just happened "I don't know... just cause" 4: it never happened the last theory is interesting to think about. it says that time is infinite and started an infinite amount of time ago, therefore the universe started an infinite amount of time ago and never actually could have been "created".
The big bang theory states that all matter was once?
Far denser -- almost infinitely more dense -- than it is today. It is a mistake to say that the BB claims that our entire Universe was once the size of a proton. That statement only applies to what is now the VISIBLE universe -- that small sub-set of our Universe that we can now see. While this 93 billion light year diameter ball is pretty large, it is impossible to determine how much more of our Universe is out there, beyond our present ability to see -- the total amount could be infinite. Thus, instead of saying our entire Universe was much SMALLER than it is today, it is more correct to say it was much DENSER.
What is the relationship between cosmic background and the big bang theory?
It follows logically from what we know about physics that the expansion of the universe from a hot and dense state should produce a remnant of microwave radiation. Reasoning from the Big Bang model (particularly the LCDM model), it is also possible to work out the intensity (temperature) of that radiation, and the nature, size and distribution of variations in that radiation. Detailed observations of the night sky have confirmed these predictions to a remarkable degree.
