COSMOLOGY

This episode is a segment that we did in the Weekly Space Hangout talking about how astronomers are using masers (water lasers) to measure the expansion rate of the Universe. You'd think that another, independent way to measure the expansion rate of the Universe would be helpful, but it's only deepened the mystery of the cosmological crisis.

Prof. Sir Martin Rees (Institute of Astronomy, Cambridge) Title: Progress and frustration in Cosmology Abstract: It is gratifying that some of the key numbers describing our Universe have been measured to a precision of a few percent. We are learning about the emergence and properties of galaxies, stars, planets and life -- and how this chain of events depended on these numbers. These advances have sharpened up new mysteries. Some of these will be clarified by new observations; others, such as the overall scale of the universe (and whether we inhabit a multiverse) are likely to prove frustratingly intractable.

It’s goes like this: the infinitely far future, when the universe has expanded exponentially to to an unthinkably large size, and every black hole and particle has decayed into faint radiation .... that infinite stretch of space and time is identically the SAME THING as the infinitesimal and instantaneous big bang of a new universe, and our universe is just one in an endless chain.

Sound Issues resolved at 15:15 There's been a lot of upheaval in the field of cosmology wrt the Hubble Constant. Two independent measurements have yielded different results and they uncertainties do not overlap. This has lead to a rethinking of many aspects of how we know what we know about the universe, including the Hubble parameter. In today's Astro Coffee Hangout, Tony and Dr. Brian Keating from the University of San Diego discuss the Hubble Constant, the problem and whether there this is actually a crisis in our understanding of the large scale structure of the universe and this important parameter. Brian Keating and Nobel Prize winner Adam Riess discussed the crisis last summer in Symmetry magazine https://www.symmetrymagazine.org/article/the-9-percent-difference “ #HubbleConstant #LiveAstronomy #DeepAstronomy Follow Brian's YouTube Channel Here: https://www.youtube.com/DrBrianKeating Get Brian's Book "Losing the Nobel Prize" here (now in paperback): http://amzn.to/2sa5UpA Interested in supporting Deep Astronomy and getting great telescope gear?

In this video, Dianna explores one of the most mysterious discoveries in physics - a constant microwave signal that seemed to be coming from everywhere in the universe. It turned out to be light from an unusual process 13.8 billion years ago.

Where do we come from? As we enter an age of unprecedented space studying and exploration, one active area of research is the story of earliest moments of cosmic time. In today's video, we retell that story; from the very earliest moment after the Big Bang, to the first stars and galaxies over 13 billion years ago. To be continued!

For some, the "Big Bang" was when the universe came into being... There was nothing before, and everything afterwards! But, what if this universe WASN'T the first of its kind? In this video, Unveiled explores the radical theories claiming that our cosmos is actually just one in a long line of alternative realities... and that somewhere out there is an "anti-universe", the perfect opposite of our own. What do you think... Did another universe exist before ours? This is Unveiled, giving you incredible answers to extraordinary questions!

Download audio http://bigpicturescience.org/episodes/radical-cosmology (repeat) 400 years ago, some ideas about the cosmos were too scandalous to mention. When the Dominican friar Giordano Bruno suggested that planets existed outside our Solar System, the Catholic Inquisition had him arrested, jailed, and burned at the stake for heresy. Today, we have evidence of thousands of planets orbiting other stars. Our discovery of extrasolar planets has dramatically changed ideas about the possibility for life elsewhere in the universe. Modern theories about the existence of the ghostly particles called neutrinos or of collapsed stars with unfathomable gravity (black holes), while similarly incendiary, didn’t prompt arrest, of course. Neutrinos and black holes were arresting ideas because they came decades before we had the means to prove their existence. Hear about scientific ideas that came before their time and why extrasolar planets, neutrinos, and black holes are now found on the frontiers of astronomical research.
