Dating the age of the universe
'young' age of the earth & universe q&a what geologic evidence supports a young age for the earth geological conflict: young radiocarbon date for ancient fossil wood challenges fossil dating diamonds: a creationist's best friend : radiocarbon in diamonds: enemy of billions of years green river blues ' instant'. Radioactive dating the technique of comparing the abundance ratio of a radioactive isotope to a reference isotope to determine the age of a material is called radioactive dating many isotopes within experimental error, this estimate agrees with the 15 billion year estimate of the age of the universe. The radioactive elements found in some meteorites provide another direct measure of the universe's age this is much like the carbon 14 dating that archaeologists use to date the remains of living creatures on earth but carbon 14 has a half-life of only 5,500 years that is, every 5,500 years one-half of the. A recent summary has been published of techniques for dating that range from astronomical methods to cover time scales from the age of the universe (eg, 13 billion years ago) to forensic entomology to determine when people died (eg, times on the order of hours) one well-known method for dating is based on the use. This would seem to indicate that the universe and the creation must be at least 5 billion years old or else we wouldn't be seeing this light in other words, if the stars were only 6 - 10,000 years old, the light from these distant galaxies would not have even reached us yet four possible solutions (1) distances in space cannot. Astronomers can place a lower limit to the age of the universe by studying globular clusters globular clusters are a dense collection of roughly a million stars stellar densities near the center of the globular cluster are enormous if we lived near the center of one, there would be several hundred thousand.
How we know the age of the earth several radioactive nuclides exist in nature with half-lives long enough to be useful for geologic dating let's go through an example of scientists have found much evidence for the big bang that created the universe 138 billion years ago this created all the building. Image of the temperature fluctuations in the cosmic microwave background created from 9 years of wmap data nasa / wmap science team the age of the universe is approximately 1377 billion years this age is calculated by measuring the distances and radial velocities of other galaxies, most of which. Estimates of the age of the galaxy, and thereby limits on the age of the universe, can be obtained by three independent means: (i) the age of the elements by radioactive dating (nucleocosmochronology) (ii) the ages of the globular clusters (the oldest stars in the halo of our galaxy) and (iii) the ages of. In physical cosmology, the age of the universe is the time elapsed since the big bang the current measurement of the age of the universe is 7001137990000000000♤13799±0021 billion (109) years within the lambda- cdm concordance model the uncertainty has been narrowed down to 21 million years, based on a.
Since the best estimates of the age of the earth come from studies using radiometric dating, it is worth asking where radioactive isotopes such as uranium- 238 come from cosmologists estimate that the universe is about 14 billion years old (see: age of the. Star date: the minimum age of the universe is calculated using a new radiometric approach new scientist 7 february 2001 astronomers used the decay of uranium-238 for the first time to date an ancient star at about 125 billion years old in the past, cosmologists have supplied the universe's age but their estimates.
Many independent measurements have established that the earth and the universe are billions of years old geologists have found annual layers in ice that are easily counted to multiple tens of thousands of years, and when combined with radio isotope dating, we find hundreds of thousands of years of ice layers using the. Effect that the physical universe itself is providing us evidence of god's design, if we are willing to pay heed are used to estimate an age for the earth and universe of about 6000 years, with a bit of uncertainty on the dating, lunar and planetary geology, meteorite specimens, stellar astronomy, and cosmology while the. How long can spam remain edible past its expiration date as with distance, scientists have developed a range of tools to measure the age of stuff in the universe from rocks, to stars, to the universe itself just like distance, it works like a ladder, where certain tools work for the youngest objects, and other. Assumptions related to “age” are not limited to radiometric dating methods perhaps some of the most egregious assumptions are associated with the “big bang” theory, the current attempt to develop an atheistic explanation for the origin of the universe serious contradictions between the predictions of the big bang theory.
The best available information indicates that the age of the universe is 137 billion years hubble has helped to measure the age of the universe using two different methods the first method involves measuring the speeds and distances of galaxies because all of the galaxies in the universe are generally moving apart, we. Though previous hubble research sets the age of the universe at 13 to 14 billion years based on the rate of expansion of space, the universe's birthday is such a fundamental and profound value that astronomers have long sought other age- dating techniques to cross-check their conclusions this new.
Dating the age of the universe
Instructionsin this activity we will begin by plotting a famous hubble diagram to demonstrate the expanding universe the first step is to find spectra for ten different type ia supernovae and work out the redshift for each using the redshift , you will derive the radial velocity for each supernova next, you will calculate the.
- In this way, astronomers have determined that, although some radioactive isotopes (such as the ones produced by the 1987 supernova) are recently formed , the oldest radioactive isotopes in the universe are 10-20 billion years old the same radioactive dating technique allows us to measure the ages of the oldest rocks on.
- Scientists say that the earth is 46 billion years old while the universe is somewhere from 10 to 20 billion years old is it true that in the '60s scientists spotted background radiation that they thought to be remnants of the big bang if this is the evidence that we base the big bang theory on, can the universe.
Therefore, by knowing a hydrogen-burning star's mass, we can determine its lifetime, which imposes a maximum age the first challenge in using this as a dating method is separating these hydrogen-burning stars from the red giants ( which are quite unstable and do not obey. Of great interest for finding an estimate for the age of the universe by determining the age of stars included in a gc one is able to obtain the age of the structure currently there are three promising techniques: the main sequence turn -off point, radioactive dating and white dwarf cooling curves the utilization of the turn-off. The current best estimate for the age of the universe is 137 billion years ( 13,700,000,000 years), with margin of error reported by nasa to be close to 1% in other words, the team of astrophysicists who published this estimate in 2003 are confident that the universe is between ~135 and ~139 billion years old, based on. As per #51 and #52, the mechanism for carbon-14 in old deposits is well understood if your sample is much older than 60,000 years, the results of carbon -14 dating are meaningless fossil wood usually can't be directly dated above that age, but you can date any surrounding volcanic.
