A NEW YORK TIMES BESTSELLER Do we have free will? Is the universe
compatible with God? Do we live in a computer simulation? Does the
universe think? Physicists are great at complicated research, but
they are less good at telling us why it matters. In this
entertaining and groundbreaking book, theoretical physicist Sabine
Hossenfelder breaks down why we should care. Drawing on the latest
research in quantum mechanics, black holes, string theory and
particle physics, Existential Physics explains what modern physics
can tell us about the big questions. Filled with counterintuitive
insights and including interviews with other leading scientists,
this clear and yet profound book will reshape your understanding of
science and the limits of what we can know.
This book summarizes recent developments in the research area of
quantum gravity phenomenology. A series of short and nontechnical
essays lays out the prospects of various experimental possibilities
and their current status. Finding observational evidence for the
quantization of space-time was long thought impossible. In the last
decade however, new experimental design and technological advances
have changed the research landscape and opened new perspectives on
quantum gravity. Formerly dominated by purely theoretical
constructions, quantum gravity now has a lively phenomenology to
offer. From high precision measurements using macroscopic quantum
oscillators to new analysis methods of the cosmic microwave
background, no stone is being left unturned in the experimental
search for quantum gravity. This book sheds new light on the
connection of astroparticle physics with the quantum gravity
problem. Gravitational waves and their detection are covered. It
illustrates findings from the interconnection between general
relativity, black holes and Planck stars. Finally, the return on
investment in quantum-gravitation research is illuminated. The book
is intended for graduate students and researchers entering the
field.
A NEW YORK TIMES BESTSELLER "An informed and entertaining guide to
what science can and cannot tell us." -The Wall Street Journal
"Stimulating . . . encourage[s] readers to push past well-trod
assumptions [...] and have fun doing so." -Science Magazine From
renowned physicist and creator of the YouTube series "Science
without the Gobbledygook," a book that takes a no-nonsense approach
to life's biggest questions, and wrestles with what physics really
says about the human condition Not only can we not currently
explain the origin of the universe, it is questionable we will ever
be able to explain it. The notion that there are universes within
particles, or that particles are conscious, is ascientific, as is
the hypothesis that our universe is a computer simulation. On the
other hand, the idea that the universe itself is conscious is
difficult to rule out entirely. According to Sabine Hossenfelder,
it is not a coincidence that quantum entanglement and vacuum energy
have become the go-to explanations of alternative healers, or that
people believe their deceased grandmother is still alive because of
quantum mechanics. Science and religion have the same roots, and
they still tackle some of the same questions: Where do we come
from? Where do we go to? How much can we know? The area of science
that is closest to answering these questions is physics. Over the
last century, physicists have learned a lot about which spiritual
ideas are still compatible with the laws of nature. Not always,
though, have they stayed on the scientific side of the debate. In
this lively, thought-provoking book, Hossenfelder takes on the
biggest questions in physics: Does the past still exist? Do
particles think? Was the universe made for us? Has physics ruled
out free will? Will we ever have a theory of everything? She lays
out how far physicists are on the way to answering these questions,
where the current limits are, and what questions might well remain
unanswerable forever. Her book offers a no-nonsense yet
entertaining take on some of the toughest riddles in existence, and
will give the reader a solid grasp on what we know-and what we
don't know.
