AI Thread Summary
New WMAP data suggests a revised estimate for Omega, potentially increasing from 1.02 to 1.04, as indicated in figures 20 and 21 on pages 48 and 49 of the linked document. The discussion encourages readers to review the data themselves for confirmation. Additional resources, including a press release and a general audience page, provide further context but offer limited insights. A graphic timeline related to cosmic microwave background findings is also highlighted. The emerging estimates from WMAP data could have significant implications for cosmological models.

http://lambda.gsfc.nasa.gov/product/map/dr2/pub_papers/threeyear/parameters/wmap_3yr_param.pdfin case you didnt see my post in Cosmology forum, check out
pages 48 and 49
figures 20 and 21

I can't say definitely but it looks like a new best estimate is emerging for Omega, which now might be more like 1.04 than the old figure of 1.02.

Cant be sure about this, see for yourself.

here is a press release, couldn't get much out of it though

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?'

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...
