- We can measure the universe (and thus extrapolate its age) out to about 100 million light years. If you draw a 1 inch circle, this represents the area of the universe we can chart, and only a couple points at that. The actual size of the universe would be a 14 foot circle around that.

Letter III According to the Book and its servants the universe is only six thousand years old. It is only within the last hundred years that studious, inquiring minds have found out that it is nearer a hundred million.

The Start of It All How can the universe be 93 billion light-years across if it is only 13.8 billion years old? Light hasn’t had enough time to travel that far…? Ultimately, understanding this facet of physics is the key to understanding what lies beyond the edge of the observable universe and whether we could ever get there.

- He took them to the Argonne National Laboratory, where he was granted time on a late-model mass spectrometer. In a meeting in Wisconsin soon afterward, Patterson revealed the results of his study. The definitive age of the Earth is 4.550 billion years (give or take 70 million years). The current estimate for the age of the earth is 4.54 ± 0.05 billion years (4.54 × 109 years ± 1%).

- The age of Earth was calculated to be about 24-40 million years based on the laws of thermodynamics. Unknown at the time was that the Earth has an internal heat source (radioactive decay) In 1899, John Joly (Irish) calculated the rate of delivery of salt to the ocean.

How can it be understood that the universe is 93 billion light years across and yet only 13.8 billion years old? There is a scale factor for the universe that is a function of time, [math]a(t)[/math]. [math]\frac{a(t_{NOW})}{a(t_{CMB})}=z+1[/math]. Which means that the diameter of those bumps that would become our CMB image would be 93 billion light years/1101 which is 84.5 million light years in diameter.

How Old is the Universe? The leftover radiation is known as the cosmic microwave background, and both WMAP and Planck have mapped it. 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.

Chronology of the universe The early universe, from the Quark epoch to the Photon epoch, or the first 380,000 years of cosmic time, when the familiar forces and elementary particles have emerged but the universe remains in the state of a plasma, followed by the Dark Ages, from 380,000 years to about 150 million years during which the universe was transparent but no ...

Transferring Credits in Graduate School For example, an English major admitted to Out-of-State University (OOSU) for the fall of 2012 might choose to take a math course at Home-State Community College during the summer of 2012, after checking to make sure that the course will fulfill the OOSU math requirement.

The Start of It All Cosmologists estimate that the oldest photons that we can observe have traveled a distance of 45-47 billion light years since the big bang. That means that our observable universe is some 93 billion light-years wide (give or take a few light years). These 93 some-odd billion light-years contain all of the quarks, quasars, stars, planets, nebulae, black holes…and everything else that we could possibly observe.

How Old is the Universe? By Nola Taylor Redd, SPACE.com Contributor | December 20, 2013 06:21pm ET. A 2013 map of the background radiation left over from the Big Bang, taken by the ESA's Planck spacecraft, captured the oldest light in the universe. This information helps astronomers determine the age of the universe.

By old-Earth creationists, young- Earth creationists, scientists, and politicians. This puts the date of creation of the universe according to a literal interpretation of the Bible at 4000 to 8000 BCE. However, old earth creationists suggest that each of the six days of creation might have taken many hundreds of millions of years.

Carl Sagan's Cosmic Calendar The Cosmic Year. The Cosmic Calendar is a scale in which the 13.7 billion year lifetime of the universe is mapped onto a single year. This image helps to put cosmology, evolution, and written history in context. At this scale the Big Bang took place on January 1 at midnight, and the current time is mapped to December 31 at midnight. At this scale, there are 434 years per second, 1.57 million years per hour, and 37.7 million years per day.

The Universe within 14 billion Light Years The Visible Universe The visible universe appears to have a radius of 14 billion light years because the universe is about 14 billion years old. The light from more distant objects simply has not had time to reach us. For this reason everybody in the universe will find themselves at the middle of their own visible universe.

How Do We Know the Age of the Universe? It is important to note that the computed age for the universe depends upon the particular version of the big bang model that is assumed: if the model changes, the age changes. The current estimated age is 13.81 billion years, with an uncertainty of 120 million years.

Measuring the age and size of the Universe The Cepheids have then been used as stepping-stones to make distance measurements for supernovae, which have, in turn, given a measure for the scale of the Universe. Today we know the age of the Universe to a much higher precision than before Hubble: around 13.7 billion years. We certainly live in exciting times.

- 1 light-year = the distance light travels in one year. If an object is 14 billion light-years away the universe must be at least 14 billion years old for the light to get to earth. Oh, also by estimating the amount of hydrogen that has been converted by stars into other heavier elements, etc.

How Big is Our Observable Universe? Some fun milestones: 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.

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.

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.

- Ultimately, this leads us to conclude that the Milky Way is 13.6 +- 0.8 billion years old. Thus, the Milky Way is essentially the same age as the universe itself. Obviously, this only serves as a rough estimate. There are about 150 additional globular clusters in the Milky Way. Some will be a tiny bit older, and some a bit younger, than this.

Holocauste Literature The best we can do is balance a lot of different measurements of the brightness and distance of stars and the red shifting of their light to come up with some ballpark figure. The oldest star clusters whose age we can estimate are about 12 to 15 billions years old. So it seems safe to estimate that the age of the Universe is at least 15 billion years old, but probably not more than 20 billion years old. This matter is far from being settled by astrophysicists and cosmologists, so stay tuned.
