In this talk; we will based on the laws of physics to illustrate the enigma time as creating our physical space (i.e., the universe). We have shown that without time there would be no physical substances, no space and no life. In reference to Einstein’s energy equation, we see that energy and mass can be traded, and every mass can be treated as an Energy Reservoir. We have further shown that physical space cannot be embedded in absolute empty space and cannot have any absolute empty subspace in it. Since all physical substances existed with time, our cosmos is created by time and every substance including our universe is coexisted with time. Although time initiates the creation, it is the physical substances which presented to us the existence of time. We are not alone with almost absolute certainty. Someday we may find a right planet, once upon a time, had harbored a civilization for a short period of light years.

Francis T. S. Yu received his B.S.E.E. degree from Mapua Institute of Technology, Manila, Philippines, and his M.S. and Ph.D. degrees in Electrical Engineering from the University of Michigan. During the period from 1958 to 1965, he was a teaching fellow, an instructor, and a lecturer in the Electrical Engineering Department at the University of Michigan, and a research associate with the Communication Sciences Laboratory at the same University. From 1966 to 1980 he was on the faculty of the Electrical and Computer Engineering Department at Wayne State University. He was a Visiting Professor in the Electrical and Computer Engineering Department at the University of Michigan from 1978-1979. In 1980 he became a Professor in the Electrical Engineering Department at The Pennsylvania State University. He has been a consultant to several industrial and government laboratories. He is an active researcher in the fields of optical signal processing, holography, optics and information theory, and optical computing. He has published over 300 refereed papers in these areas. He is a recipient of the 1983 Faculty Scholar Medal for Outstanding Achievement in Physical Sciences and Engineering, a recipient of the 1984 Outstanding Researcher in the College of Engineering, was named Evan Pugh Professor of Electrical Engineering in 1985 at Penn State, a recipient of the 1993 Premier Research Award from the Penn State Engineering Society, was named Honorary Professor in Nankai University in 1995, the co-recipient of the 1998 IEEE Donald G. Fink Prize Paper Award, named Honorary Professor in National Chiao Tung University Taiwan in 2004, the recipients of the 2004 SPIE Dennis Gabor Award, and the 2017 OSA Emmet N. Leith Medal. Dr. Yu retired from Penn State University in 2004. Dr. Yu is a life-fellow of IEEE and fellow of OSA, SPIE, and PSC.
