Universe Older Than 14 Billion Years. Astronomers refined the star's age to about 14.5 billion years (which is older than the universe), plus or minus 800 million years. Image released march 7, 2013.
Universe is nearly 14 billion years old by linda b. Web scientists’ best estimate is that the universe is about 13.8 billion years old. But earlier estimates from observations dating back to 2000 placed the star as old as 16 billion years.
Web Can The Universe Be Older Than 14 Billion Years?
But earlier estimates from observations dating back to 2000 placed the star as old as 16 billion years. Web in 2013, a measurement of the methuselah star suggested that it is 14.45 billion years old — older than the age of the universe. Image released march 7, 2013.

Astronomers refined the star’s age to about 14.5 billion years (which is older than the universe), plus or minus 800 million years. Web with careful measurements of the star’s metallicity, particularly iron and oxygen, the authors calculate the age of hd 140283 to be 14.46 billion years, with an uncertainty of 800 million years. In comparison, the solar system is only about 4.6 billion years old.

Web for years, astronomers and physicists have calculated the age of our universe by measuring the time elapsed since the big bang and by studying the oldest stars based on the redshift of light. Until recently, astronomers estimated that the big bang occurred between 12 and 14 billion years ago. Web the star could be as old as 14.5 billion years (plus or minus 0.8 billion years), which at first glance would make it older than the universe's calculated age of about 13.8 billion years, an obvious dilemma.
The Universe Might Well Be Older Than 14 Billion Years, And We Should Stop Putting A Limit On It Every Time Something New Is Discovered.
Web the universe is (nearly) 14 billion years old, astronomers confirm. Web so a rough estimate of the age of the universe comes from the hubble time, the inverse of the hubble parameter. With looming discrepancies about the true age of the universe, scientists have taken a fresh look at the observable.
Web Scientists’ Best Estimate Is That The Universe Is About 13.8 Billion Years Old.
Web january 4, 2021 astronomers agree: † † because the universe was opaque the first 380,000 years, we can't see all the way, but that's a technical detail. To put this in perspective, the solar system is thought to be 4.5 billion years old and humans have existed as a genus for only a few million years.
