- It is the story of a scientific triumph.--Kulvinder Singh Chadha, Physics World. This is a very engaging and readable book that will help you wrap your mind around an agreed to astronomical actuality: The universe is 13.7 billion years old.

Age of the Universe (to + tSS)/2 = 8-11 Gyr which we can solve for the age of the Universe giving to = 11.5-17.5 Gyr. 238U and 232Th are both radioactive with half-lives of 4.468 and 14.05 Gyrs, but the uranium is underabundant in the Solar System compared to the expected production ratio in supernovae.

Experience Just How Big the Universe is, in One Mind-Blowing Interactive The size of the observable universe (10^26 m) This is far as anything on Earth can see. The age of the universe is 14 billion years, so in theory we are unable to observe anything further than 14 billion light-years away.

- We can observe only a portion of the entire universe. Because the universe is only about 14 billion years old, light has only had about 14 billion years to travel through it. Therefore, the most distant regions of the universe we can see are about 14 billion light-years away. This is the extent of the observable universe, but the entire universe is probably much larger. It could even extend infinitely in all directions.

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.

rudder and daggerboard for sunfish Re: rudder and daggerboard for sunfish. I vote for marine plywood. I don't have bad experience with solid wood... but I can say that I am still sailing the original rudder and daggerboard on a boat that my father built in 1967. No splitting, no warping.

Star Most stars are between 1 billion and 10 billion years old. Some stars may even be close to 13.8 billion years old—the observed age of the universe. The oldest star yet discovered, HD 140283, nicknamed Methuselah star, is an estimated 14.46 ± 0.8 billion years old.

The Farthest Visible Reaches of Space Scientists have estimated the age of the Universe to be 13.73 billion years old (with an uncertainty of about 120 million years). When we observe an object that is 13 billion light years away, we are essentially observing it as it was 13 billion years ago, when the Universe was young.

Title of farthest known object in universe has new champ The object is very young, and it also dates from an epoch when the universe itself was still a baby, just 420 million years old, or 3 percent of its present age.

How Big is the Universe? A finite universe has a finite size that can be measured; this would be the case in a closed spherical universe. But an infinite universe has no size by definition. According to NASA, scientists know that the universe is flat with only about a 0.4 percent margin of error (as of 2013).oday, that same spot is 46 billion light-years away, making the diameter of the observable universe a sphere around 92 billion light-years.

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.

Contents The only trick is to remember that 100 = 1. Using powers-of-ten notation, the age of the universe is 1.5 x 1010 years and the distance to the Sun is 1.496 x 1011 meters. The general form of a number in scientific notation is a x 10n, where a must be between 1 and 10, and n must be an integer.

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.

If God Created Everything, Who Created God? by Rich Deem 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.

Universe Or universe? It All Depends On The Multiverse First, since nothing travels faster than light, information from a far away object like a galaxy takes time to reach us. Second, the cosmos we live in is time limited, starting 13.7 billion years ago in the event we call Big Bang (capitalized or not? [Editor's Note: Not. But we can change that policy today, too!]).

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.

- It's very difficult to answer this question as spiral galaxies have different ages. The Milky Way Galaxy-our galaxy-is approximately 13.2 billion years old, nearly as ol … d as the Universe as a star HE 1523-0901, was estimated to be about that old.

Age of the universe In 2015, the Planck Collaboration estimated the age of the universe to be 7001138130000000000♠13.813±0.038 billion years, slightly higher but within the uncertainties of the earlier number derived from the WMAP data.

The Age of the Earth The age of the elements in the Galaxy, based on the production ratios of osmium isotopes in supernovae and the change in that ratio over time due to radioactive decay, is 8.6-15.7 billion years. Theoretical considerations indicate that the Galaxy formed within a billion years of the beginning of the Universe.

"Giant ""Blob"" Is Largest Thing in Universe" Because the object is so far away, the astronomers are actually looking at something from 12 billion years ago, a mere 2 billion years after the universe is believed to have been formed in the big bang. This young galactic blob could reveal how and when the earliest galaxies formed.

Title of farthest known object in universe has new champ The new record holder is the galaxy MACS0647-JD, which is about 13.3 billion light-years away. The universe itself is only 13.7 billion years old, so this galaxy's light has been traveling toward us for almost the whole history of space and time.

- 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.

How Old is the Universe? Astronomers estimate the age of the universe in two ways: 1) by looking for the oldest stars; and 2) by measuring the rate of expansion of the universe and extrapolating back to the Big Bang; just as crime detectives can trace the origin of a bullet from the holes in a wall.

Age of the Earth “Scientific” Arguments for an Old Earth. We commonly hear scientific-sounding arguments that the earth and universe are billions of years old. We are told radiometric dating shows that certain rocks formed billions of years ago.
