AI Thread Summary
The age of the universe is estimated to be approximately 13.7 billion years, primarily based on data from the Wilkinson Microwave Anisotropy Probe (WMAP). Various methods exist for calculating this age, all yielding consistent results. Resources like specific forum posts and the UCLA astrophysics website can provide detailed explanations of these calculations. Understanding cosmic background radiation and the expansion of the universe are key components in these estimations. The consensus among scientists supports this age as the most accurate measurement to date.

Hi everyone,

Could someone tell me the details on how to calculate the age of the universe?
I've read online that it is about 13 billion years old but I can't find anywhere that tells me how they got to this number without confusing the hell out of me. Can anyone fill me in?

Thanks.

Hi TheSpecialist, welcome to these Forums!
How do you find the age of the universe? Try here post #26, and here, post #66.

I hope these help.

Hi TheSpecialist, and also welcome. There are several different ways of estimating the age of the universe and all of them yield similar results:

WMAP has provided what is believed to be the most precise estimate to date - 13.7 billion years.
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
