Professor Silk will describe the state of our knowledge of neutron stars and black holes, and how new observations of gravity waves are poised to revolutionise this field.
I will argue for the essential unity of speech and gesture in the transmission of thought, and suggest that we have underestimated the considerable communicative significance of these movements.
Asteroid impact could devastate the Earth, although preventive measures might detect and monitor orbits of potential killer asteroids. Longer term, the sun will evolve into a red giant and expand to a hundred times the orbit of the earth.
What are the implications of the Big Bang for our understanding of ourselves? Is the universe meaningless? or is there some way of developing a ‘big picture’ of reality that helps us decide our place and purpose in the universe.
Matter consists of a mêlée of elementary particles. There are protons and neutrons, made up of quarks, and many other short-lived massive particles. One hope is to discover particles of dark matter, but this has so far eluded our best efforts.
View the sky through an x-ray telescope and the conception of the universe changes dramatically. Black holes are best seen in x-rays, because impinging gas collides with the black hole at near light speed, resulting in intense x-ray and gamma ray emission.
Isaac Newton saw his demonstration of the regularity of the universe as having great religious significance. Newton’s ideas were initially seen as very supportive of religion; yet within 50 years, they were being seen in a very different light.
Catherine Roach uncovers what we learn from the romance story about today’s changing norms for gender and sexuality and about the nature of happiness and love.
Theories of the multiverse suggest that life-containing universes are incredibly rare. We live in one of these, whether by cosmological natural selection or by the consequences of a theory yet to be formulated.
