The Fabric of the Cosmos : Space, Time, and the Texture of Reality
I picked this book - The Fabric of Cosmos: Space, Time, and Texure of Reality - up Saturday afternoon, and read the first 3 chapters.
I decided that I have been reading too many fiction lately,
and haven’t read much non-fiction. Every now and then, it’s good to pick
up some heavier material to occupy your brain with. And there’s
probably not much material out there heavier than the nature of space
and time.
Is space an entity? Why does time have a direction? Could the
universe exist without space and time? Can we travel to the past? The
ultimate questions pondered by philosophers and physicist throughout
history.
The book has a very minimalist and yet elegant cover, it’s the
picture of some out of focus fabric, which matches the book’s title.
Brian Greene, one of the world’s leading physicists who teaches at
Columbia University, is set out to describe superstring and M-theory to
the general public in this book. As he described early on in the book,
we as humans gain appreciation for our world, when we truly understand
the inner workings and truth of things beyond our limited senses.
Yes,
we can no doubt look up the night sky and see and appreciate the
vastness of space and time with our eyes, but this is not what drives
scientists.
Scientists want “to assess life and to experience the
universe at all possible levels, not just those that happened to be
accessible to our frail human senses.” It’s a passion for beauty and
truth. In fact the basis for string theory is the believe that theory of
general relativity (works well on big objects and distances) and theory
of quantum mechanics (works well on small objects and distnaces) should
not contradict.
String theorists are believers of an elegant universe,
that there ought to be one way to describe the nature of all things.
