How can the age of the universe be determined?

The age of universe can be determined by imaging what the universe looked like in the past, “rewinding” the expansion. In the past the galaxies must have been closer together, and in the distant past they would have been packed together in a tiny point.

How does the universe actually work?

The universe actually works as a sort of “time machine,” in which we can see into the past simply by looking far away. The calculation of the light travel time is simple once you know the speed of light and have a measurement of the distance.

How old is the Earth and universe?

Light from galaxies is reaching us billions of years after it left, and the expansion rate of the universe dates its age to 13.8 billion years. These are just a sampling of the types of evidence for the great age of the Earth and the universe; see the resources below for more. Davis A. Young, ”How Old Is It? How Do We Know?

Do young Earth creationists reject radiometric dating methods?

Young Earth Creationists reject radiometric dating methods, including claims that decay rates are not constant. For a critical review, see Randall Isaac “Assessing the RATE Project,” Perspectives on Science and Christian Faith, vol 59, no 2, June 2007, p.143-146. ( PDF) See Davis A Young, ”How Old Is It? How Do We Know?

How do we know the age of the universe?

The age of the universe can be determined by measuring the Hubble constant today and extrapolating back in time with the observed value of density parameters (Ω). Before the discovery of dark energy, it was believed that the universe was matter-dominated ( Einstein–de Sitter universe, green curve).

How old is the universe according to Einstein?

Before the discovery of dark energy, it was believed that the universe was matter-dominated ( Einstein–de Sitter universe, green curve). Note that the de Sitter universe has infinite age, while the closed universe has the least age. Ω Λ . {/displaystyle ~/Omega _ {/Lambda }~.}

How old is the universe according to Planck?

The age of the universe based on the best fit to Planck 2015 data alone is 13.813 ± 0.038 billion years (the estimate of 13.799 ± 0.021 billion years uses Gaussian priors based on earlier estimates from other studies to determine the combined uncertainty).

How old is the universe minus 1 second ago?

If one referred to the same point in time as 13.77 billion years minus 1 second ago, the precision of the meaning would be lost because 1 second is minuscule compared to uncertainty in the estimated 13.77 billion year age of the universe: The probable error (order of tens to hundreds of millions of years) eclipses the specified time (a second).

The Bible never says that the earth is 6000 years old . So from where do they get it? What they will do is follow the genealogy reports in the Old Testament and counts the years that are recorded. Upon doing this, they are able to count out 6000 years.

Does radiometric dating have any scientific merit?

The topic of radiometric dating (and other dating methods) has received some of the most vicious attacks by young earth creation science theorists. However, none of the criticisms of young earth creationists have any scientific merit.

Are the criticisms of young Earth creationists scientifically valid?

However, none of the criticisms of young earth creationists have any scientific merit. Radiometric dating remains a reliable scientific method. For articles on the RATE project, see the Rate Index.

How old is the Earth according to creationists?

The young Earth creationist belief that the age of the Earth is 6,000 to 10,000 years old conflicts with the age of 4.54 billion years measured using independently cross-validated geochronological methods including radiometric dating.

Why doesnt radiocarbon dating work on objects older than 20 thousand years?

Radiocarbon dating doesnt work well on objects much older than twenty thousand years, because such objects have so little C-14 left that their beta radiation is swamped out by the background radiation of cosmic rays and potassium-40 (K-40) decay.
