Focusing on the ultimate limits of observational astronomy, Harwit explores how well we will ever understand the Universe.

Martin Harwit, author of the influential book Cosmic Discovery, asks key questions about the scope of observational astronomy. Humans have long sought to understand the world we inhabit. Recent realization of how our unruly Universe distorts information before it ever reaches us reveals distinct limits on how well we will ultimately understand the Cosmos. Even the best instruments we might conceive will inevitably be thwarted by ever more complex distortions and will never untangle the data completely. Observational astronomy, and the cost of pursuing it, will then have reached an inherent end. Only some totally different lines of approach, as yet unknown and potentially far more costly, might then need to emerge if we wish to learn more. This accessible book is written for all astronomers, astrophysicists, and those curious about how well we will ever understand the Universe and the potential costs of pushing those limits.

Cosmic Messengers is a roadmap home to understanding soul, your place in the universe and the role of cosmic energy in accelerating your life purpose. As you awaken to a higher consciousness, you can remember why you're here, what you're good at and how you can fulfil your purpose, all with an energetic momentum. By becoming 'cosmically aware' you'll develop a deeper appreciation of your reason for being, and how you can impact the globe with your unique talents and skills. There are thirteen 'universal secrets' which, when applied, will accelerate your life purpose. You'll learn about energy, dimensions, planetary bodies, the human soul and personality, our spiritual reality, cosmic awareness, our spirit and angelic guides, momentum, resistance, the power of secrecy and using our imagination and intuition to walk our unique path. Plus, there are two valuable reference guides detailing 'The Common Physical Symptoms of Energy Shifts and Accelerating Your Life Purpose' and 'The Cosmic Reasons for Physical, Emotional, Mental and Spiritual Life Issues'. You'll be actively engaged throughout Cosmic Messengers via self-enquiry practices and guided meditations, which reinforce your understanding of who you are and your role in the cosmos. You'll receive answers from within, learn how to draw out your ancient wisdom and be guided to put your innate knowledge, skills and talents to work in living on purpose and becoming your own life guide.

NEW YORK TIMES BESTSELLER Bringing his cosmic perspective to civilization on Earth, Neil deGrasse Tyson shines new light on the crucial fault lines of our time—war, politics, religion, truth, beauty, gender, and race—in a way that stimulates a deeper sense of unity for us all. In a time when our political and cultural views feel more polarized than ever, Tyson provides a much-needed antidote to so much of what divides us, while making a passionate case for the twin chariots of enlightenment—a cosmic perspective and the rationality of science. After thinking deeply about how science sees the world and about Earth as a planet, the human brain has the capacity to reset and recalibrates life’s priorities, shaping the actions we might take in response. No outlook on culture, society, or civilization remains untouched. With crystalline prose, Starry Messenger walks us through the scientific palette that sees and paints the world differently. From insights on resolving global conflict to reminders of how precious it is to be alive, Tyson reveals, with warmth and eloquence, an array of brilliant and beautiful truths that apply to us all, informed and enlightened by knowledge of our place in the universe.

The book describes from a historical point of view how cosmic rays were discovered. The book describes the research in cosmic rays. The main focus is on how the knowledge was gained, describing the main experiments and the conclusions drawn. Biographical sketches of main researchers are provided. Cosmic rays have an official date of discovery which is linked to the famous balloon flights of the Austrian physicist Hess in 1912. The year 2012 can therefore be considered the centenary of the discovery.

This book, designed as a tool for young researchers and graduate students, reviews the main open problems and research lines in various fields of astroparticle physics: cosmic rays, gamma rays, neutrinos, cosmology, and gravitational physics. The opening section discusses cosmic rays of both galactic and extragalactic origin, examining experimental results, theoretical models, and possible future developments. The basics of gamma-ray astronomy are then described, including the detection methods and techniques. Galactic and extragalactic aspects of the field are addressed in the light of recent discoveries with space-borne and ground-based detectors. The review of neutrinos outlines the status of the investigations of neutrino radiation and brings together relevant formulae, estimations, and background information. Three complementary issues in cosmology are examined: observable predictions of inflation in the early universe, effects of dark energy/modified gravity in the large-scale structure of the universe, and neutrinos in cosmology and large-scale structures. The closing section on gravitational physics reviews issues relating to quantum gravity, atomic precision tests, space-based experiments, the strong field regime, gravitational waves, multi-messengers, and alternative theories of gravity.
