Cosmology: the Origin of the Universe

Give a patch to the Big Bang theory of the universe and explain the origin of the universe from its roots. The book is not long, less than 50 chapters, but it is very brain-burning and needs to be savored carefully. This book contains a lot of pretentious knowledge. I hope readers will not misinterpret it, let alone publish it online to gain traffic. All intellectual property rights are owned and violators will be prosecuted.
