AGE OF THE EARTH The age of 4.54 billion years found for the Solar System and Earth is consistent with current calculations of 11 to 13 billion years for the age of the Milky Way Galaxy (based on the stage of evolution of globular cluster stars) and the age of 10 to 15 billion years for the age of the Universe (based on the recession of distant galaxies).

- Most physicists believe the earth is 4.5 billion years old. And the results of Terra, run with that assumption, works out OK. On the other hand, run the program assuming the earth is less than 10,000 years old, and that there was a catastrophic universal Flood, and all the geology works out OK that way also!

- Oxidation and Reduction (redox) reactions are complementary reactions that involve the transfer of electrons from one molecule or ion (reductant) to another (oxidant). They always work in concert with one-another. That is, whenever an oxidation reaction occurs, so does a reduction reaction.igure 1: Reaction (a) is a redox reaction and reaction (b) is not. Chemists use a conceptual tool called the oxidation number (oxidation state) as a means of keeping track of the number of electrons borne by each atom in a molecule or ion.

Milky Way The Milky Way is a barred spiral galaxy that has a diameter usually considered to be roughly 100,000–120,000 light-years but may be 150,000–180,000 light-years.The Milky Way is estimated to contain 200–400 billion stars, although this number may be as high as one trillion.There are probably at least 100 billion planets in the Milky Way.everal individual stars have been found in the Milky Way's halo with measured ages very close to the 13.80-billion-year age of the Universe. In 2007, a star in the galactic halo, HE 1523-0901, was estimated to be about 13.2 billion years old.

How Many Stars are There in the Universe? And so, if you multiply the number of stars in our galaxy by the number of galaxies in the Universe, you get approximately 10 24 stars. That’s a 1 followed by twenty-four zeros. That’s a septillion stars. But there could be more than that.It’s been calculated that the observable Universe is a bubble of space 47 billion years in all directions. It defines the amount of the Universe that we can see, because that’s how long light has taken to reach us since the Big Bang.ur Sun is located about 27,000 light-years from the galactic core in the Orion arm. Astronomers estimate that the Milky Way contains up to 400 billion stars of various sizes and brightness. A few are supergiants, like Betelgeuse or Rigel.

How Old is the Universe? The universe cannot be younger than the objects contained inside of it. By determining the ages of the oldest stars, scientists are able to put a limit on the age. The life cycle of a star is based on its mass. More massive stars burn faster than their lower-mass siblings.

Observable universe For other uses, see Universe (disambiguation). The Universe is all of time and space and its contents. It includes planets, moons, minor planets, stars, galaxies, the contents of intergalactic space, and all matter and energy. The observable universe is about 28 billion parsecs (91 billion light-years) in diameter. The size of the entire Universe is unknown, but there are many hypotheses about the composition and evolution of the Universe.

- It goes like this: If the age of the universe is truly about 13.7 billion years old as scientists have ascertained and if God truly created the universe in 6 days, as inspirers of the Bible have ascertained, then each Biblical day should be 13.7 billion years (13.7 x 10e9) / 6 = 2.283 billion years long.

Belief that the Universe is only a few thousand years old? There is no debate. The universe is an unknown number of billions of years old. Only entrenched creationists still insist that the Earth, for example, is only 6,000 years old, using their unique brand of pseudo-science to prove it. They are the laughingstock of the scientific community.here is rather sufficient evidence that the world is millions of years old, so that means that the universe must be an unimaginable multitude times older.

Q: How far away is the edge of the universe? January 13, 2010. Physicist: If you ever hear a physicist talking about “the edge of the universe”, what they probably mean is “the edge of the visible universe”. The oldest light (from the most distant sources) is around 15 billion years old.

- 1 The diameter of the Milky Way is 100,000 light years; the observable Universe had this as its radius when it was approximately 3 years old.  When the Universe was one year old, it was much hotter and denser than it is now. The mean temperature of the Universe was more than 2 million Kelvin.

How Old is the Universe? In 2012, WMAP estimated the age of the universe to be 13.772 billion years, with an uncertainty of 59 million years. In 2013, Planck measured the age of the universe at 13.82 billion years. Both of these fall within the lower limit of 11 billion years independently derived from the globular clusters, and both have smaller uncertainties than that number.

Age of the Universe The age of the Universe can also be estimated from a cosmological model based on the Hubble constant and the densities of matter and dark energy. This model-based age is currently 13.75 +/- 0.1 Gyr. But this Web page will only deal with actual age measurements, not estimates from cosmological models.

The Age of the Universe You can actually calculate an estimate for the age of the Universe from Hubble's Law. The distance between two galaxies is D. The apparent velocity with which they are separating from each other is v. At some point, the galaxies were touching, and we can consider that time the moment of the Big Bang.

No Big Bang? Quantum equation predicts universe has no beginning The widely accepted age of the universe, as estimated by general relativity, is 13.8 billion years. In the beginning, everything in existence is thought to have occupied a single infinitely dense point, or singularity. Only after this point began to expand in a Big Bang did the universe officially begin. Although the Big Bang singularity arises directly and unavoidably from the mathematics of general relativity, some scientists see it as problematic because the math can explain only what happened immediately after—not at or before—the singularity.

How Big is the Universe? If the universe was formed 13 billion years ago as a result of a big bang (or some other mechanism), this young age of 10,000 years does not seem reasonable. However, a straightforward reading of the creation account in Genesis does not allow for the universe (and our world) to evolve over billions of years.

How are the ages of the Earth and universe calculated? Layers in glaciers show a history much longer than 10,000 years, and radiometric dating places the formation of the Earth at 4.5 billion years. Light from galaxies is reaching us billions of years after it left, and the expansion rate of the universe dates its age to 13.7 billion years.

The Beginning of Time The conclusion of this lecture is that the universe has not existed forever. Rather, the universe, and time itself, had a beginning in the Big Bang, about 15 billion years ago. The beginning of real time, would have been a singularity, at which the laws of physics would have broken down.
