On December 3, 2015, the European Space Agency (ESA) announced that it had successfully launched the LISA Pathfinder probe to verify technology for detecting gravitational waves in space.
LISA Pathfinder is a satellite designed to verify the technology needed to build the Advanced Laser Interferometer Space Antenna (eLISA), which is scheduled to be launched in 2034 to detect gravitational waves in space.
Gravitational waves, which can be said to be ripples in space-time that are spread throughout the universe, are the final touchstone to verify Einstein's general theory of relativity, which celebrated its 100th anniversary this year, and are also a powerful observational tool that humanity will use in the future to explore and explore the entire space-time of the universe and even other universes.
If the LISA Project, which began with LISA Pathfinder, succeeds in directly detecting gravitational waves, the intellectual achievements of physics and science, which have explored the fundamental structure and laws of the universe, will be able to skip several steps.
In fact, LISA Pathfinder was scheduled to launch on December 2nd, exactly 100 years after Einstein published his theory of general relativity.


One hundred years after the publication of Einstein's general theory of relativity, physics is undergoing revolutionary advancements.
Remarkable progress is being made in two fields with extremely different scales: particle physics, which deals with extremely small objects on the order of tens of meters square, and cosmology, which deals with super-large celestial bodies such as the universe, galaxy clusters, and galaxies that are hundreds of billions of light-years in size. The discovery of the Higgs boson at the Large Hadron Collider (the Large Hadron Collider operated by CERN, the European particle physics laboratory), the discovery of the accelerating expansion of the universe that indicates that the expansion of the universe is accelerating day by day, and the elucidation of the history of the universe's evolution from the cosmic microwave background radiation. For decades, physicists have only been theoretically guessing, like the blind men and the elephant, but now they are being revealed concretely and quantitatively, leading physicists into the future.
Moreover, despite their vast differences in scale, the research in particle physics and cosmology is rapidly overlapping and merging, making it difficult even for the physicists themselves to predict the future.


Just as Einstein's theory of relativity and quantum mechanics, which were developing at the same time 100 years ago, met and changed not only physics and science, but also engineering and technology, and even philosophy and thought, and society and civilization as a whole (Einstein's mass-energy equivalence and nuclear physics met and gave birth to the atomic bomb, and general relativity met and electrodynamics gave birth to GPS), the particle physics-cosmology revolution taking place in the early 21st century will completely change human civilization in the latter half of the 21st century from what it is now.

In the book Knocking on Heaven's Door by Harvard University Professor Lisa Randall, published by Science Books, you can hear vividly what is happening at the forefront of modern physics where particle physics and cosmology overlap, and what kind of physics physicists dream of for the future, through the voice of the world's top female physicist who is actively working in that field.


A must-read for all of us who must live in a universe filled with mysteries.
-Hitoshi Murayama (Director, Kavli Institute for Cosmological Physics and Mathematics, International Institute for Advanced Study, University of Tokyo)

Lisa Randle is literally a rare creature.
He is a genius physicist who writes books and gives lectures so that even those of us who are not can understand.
This book will guide non-experts into the inner workings of the universe, a space previously inaccessible to even the most inexperienced.
-Lawrence Summers (former Dean of the Harvard Graduate School)

Theoretical physicist Lisa Randall is famous for being the first woman to hold a tenured professorship in physics at Harvard University and MIT.
Academically, he is renowned for creating twisted extradimensional physics by applying concepts from string theory and topology.
Born in 1962, he shocked the world of physics in 1999, around the turn of the century, when he published a paper titled “Warped Extra Dimensions” with Dr. Raman Sundrum.
This paper made some of the research results of string theory, which were thought to be abstract and impossible to verify, experimentally verifiable, and attracted the attention of scientists seeking the future of physics, becoming the most cited theoretical physics paper of the 21st century.
As a result, Lisa Randall became one of the most influential theoretical physicists of the modern century.


The extra-dimensional theory she proposed, called the 'Randall-Sundrum model', is highly regarded as a clue to solving many difficult problems in modern theoretical physics, and is serving as a guideline for designing new experiments at the Large Hadron Collider (LHC) operating in Geneva, Switzerland.
Randall has also contributed to inflationary cosmology, supersymmetry theory, grand unification theory, and string theory.
For these achievements, the American Physical Society awarded Randle the 'Most Cited Paper Award', and he swept many prestigious academic research awards, including the Alfred Sloan Foundation Research Award. He is also an active member of academic institutions such as the National Academy of Sciences and the American Philosophical Society, which are considered hallmarks of intellect.


Her achievements have been mentioned in various scientific media such as Discovery, The Economist, Newsweek, and Scientific American, as well as professional academic journals such as Physics Letters, Nature, and Science, and media outlets such as Seed Magazine, Newsweek, Rolling Stone, and Time have also highlighted her achievements and status with titles such as “100 Most Influential People in the World.”


His first book, "Warped Passages," was translated and published in over 20 countries, including the West, Korea, and Japan, becoming a bestseller in science fiction circles worldwide. It was also selected as one of the "Books of the Year" by The New York Times.


Knocking on Heaven's Door, a prequel to "The Hidden Universe"
What exactly does it mean to do science?

This book explores all aspects of the universe—from the vast expanses of cosmology to the microscopic realms of particle physics. It will be the ultimate guide for avid science readers seeking to understand the purpose of the LHC.
-Elon Musk (CEO of Tesla Motors, SpaceX, co-founder of PayPal)

This book clearly explains the fundamentals of modern physics research and the nature of recent experiments.
Lisa Randle's commentary is also one of the best explanations for non-physicists.
If you want to understand how our future will change, this book is a must-read.
-Craig Venter (the first artificial life synthesizer and human genome decipherer)

Many books elevate our minds.
This book has all the advantages of those books.
This book describes one of the greatest scientific endeavors in history.
It seeks to explain the fastest, largest, and most powerful phenomena in our universe, and to answer the deepest questions about the physical reality of nature that confront us.
Lisa Randle's lucid and enlightening presentation of the many ideas just emerging and taking shape at the forefront of modern physics is dazzling and inspiring.
I welcome her efforts to champion science and reason.
Reading this book today will be the starting point for understanding tomorrow's science.
-Steven Pinker (author of The Language Instinct and The Blank Slate, Harvard professor)

Lisa Randall's second work, Waiting for Heaven's Gate, also became a science bestseller in the United States and Europe immediately after its publication and was selected as one of the "100 Notable Books" by the New York Times Book Review, garnering keen interest from science readers.
In this book, Lisa Randall connects particle physics and cosmology, whose scales differ by a factor of 10 to the 60th power, just as she used the twisted spacetime geometry of her previous work, The Hidden Universe, to connect hidden dimensions with the three-dimensional world of our universe.

Lisa Randall calls her new book a sequel to The Hidden Universe, but also a “prequel.”
In this book, Randall emphasizes that the most fundamental constituents of the objects we encounter in our daily lives, such as atoms and quarks, are governed by laws that are safely different from the everyday laws of physics that we intuitively know.
For example, an atom that makes up a hard chair is 99.999999 percent empty space, except for the nucleus and electrons, and gravity, the driving force that makes us drop a thrown ball and moves the sun and moon, is a very, very weak force, 10 to the 16th power, in the subatomic world.


In the world of physics, the laws of physics appear to change as the size scales and energy scales of objects change.
So how can the laws governing the smallest things be in harmony with the laws governing the largest? Aren't the laws governing the smallest things used to explain the countless phenomena we observe in the universe? Quantum mechanics is currently being applied not only in physics but also in chemistry, biology, electrical engineering, computer science, and other diverse fields.
How can the laws of physics, which vary with each scale, be applied across such scales? This question is a fundamental question of the discipline of physics.
The question is how a science called physics is possible.
In answering the question of how the dazzling leap and convergence from particle physics to cosmology, as shown in "The Hidden Universe," is possible, Lisa Randall explores the values, history, and foundations of physics and science in this book, invoking Galileo, who continued his research even while in conflict with the dominant religion of the time.
So it is a prequel to 『Hidden Universe』.

What is the Higgs particle and dark matter?
And what dimension do we live in?
What answers will cutting-edge experiments, including the LHC, bring?

The LHC achieved the remarkable discovery of the Higgs boson shortly after it began operation in 2009.
The final piece of the puzzle of the Standard Model of particle physics, which had been missing for over 40 years, has been put into place.
In this book, Lisa Randall sings a hymn to the LHC, the frontline base for modern physicists tackling the mysteries of the universe, and an epic poem introducing its history and full story.


The LHC, which started as a true international joint research project, went through many twists and turns to become the 'machine' that currently produces the closest energy to the Big Bang on Earth. We will guide you through every corner of the LHC, where extreme technologies that modern engineers can realize are in operation, such as superconducting magnets that contain the energy of hundreds of tons of TNT and ultra-low temperature and ultra-vacuum technologies that produce a space colder and thinner than space.
The film vividly illustrates how scientists think and take action to prevent potential mishaps from their research, using a controversial issue like the one concerning the possibility that a black hole created at the LHC could put Earth at risk of extinction.


Lisa Randall compares the strengths and weaknesses of scientific research methodology with those of other fields, such as finance, economics, politics, and society, by designing research and experiments, reviewing safety, and meticulously intertwining them to ensure that current experiments serve as the cornerstone of future research. She presents a detailed and unparalleled overview of the pros and cons of scientific research methodology.
Richard Dawkins, a renowned evolutionary biologist and critic of religion, praised Lisa Randle's efforts and even gave her the title of "Champion of Science and Reason."


However high Lisa Randle's assessment of the current experiments and research at the LHC is, the current research is not the whole story in this book.
Lisa Randall also explores how current experiments lay the foundation for future physics. She details experiments and theories that will become cornerstones of future physics, including the potential results of proton collision experiments at the Large Hadron Collider (LHC), the identification of dark matter, the discovery of clues to the mystery of dark energy, the detection of traces of supersymmetric particles that will prove supersymmetry, and the discovery of the Kaluza-Klein particle, which will confirm Randall's own theory of the "twisted extradimensional model" and reveal the existence of higher-dimensional universes hidden within our own.
It can literally be called a guidebook for future physics.

A must-read for the new future unfolding through modern physics.
A new navigational chart that guides you through the twisted fifth-dimensional universe

As we enter the first decade of the 21st century, physics is undergoing a profound transformation in our understanding of the most fundamental fundamental structures of the universe.
This will likely result in a paradigm shift, perhaps accompanied by a rapid scientific revolution.
Our understanding of the universe could be fundamentally transformed in just a decade. Beginning with the LHC, experiments and theoretical challenges are underway, both on Earth and in space, that no one could have imagined in the 400 years since Galileo.
Cutting-edge modern physics will knock on the gates of heaven, where scientific truths lie hidden, and usher us into a new era of understanding the universe and the world.


Now the mystery of the origin and destiny of the universe is beginning to be dramatically solved.
It's time to embark on a grand adventure into a new universe, with a clear explanation from Lisa Randall, a professor of physics at Harvard University who is at the forefront of modern physics development.
