Dimensions Quote by Edward Witten

The theory has to be interpreted that extra dimensions beyond the ordinary four dimensions the three spatial dimensions plus time are sufficiently small that…

It's not completely obvious what gravity is, fundamentally, or what dimensions are, fundamentally. One of these days we'll understand better what we mean, what…

— Lisa Randall

Even in relativity theory even though you can analyze space - time in terms of this four-dimensional geometrical structure one of the dimensions is…

— William Lane Craig

“In the early universe—when the universe was small enough to be governed by both general relativity and quantum theory—there were effectively four dimensions of…

— Stephen Hawking

If I take the theory as we have it now, literally, I would conclude that extra dimensions really exist. They're part of nature. We…

— Edward Witten

One of the weird things about modern physics is that we do find there are apparently these other dimensions that we don't directly experience…

— David Grinspoon

Extra dimensional theories are sometimes considered science fiction with equations. I think that's a wrong attitude. I think extra dimensions are with us, they…

— Leonard Susskind

Space is certainly something more complicated than the average person would probably realize. Space is not just an empty background in which things happen.

— Alan Guth

“The lack of time and space in our sense of these concepts does not mean that nothing exists beyond the spacetime continuum.”

— Dejan Stojanovic

“Insofar as the general theory of relativity follows Mach's ideas, it can be seen as expressing the distribution of masses in terms of properties…

— Henning Genz

Relativity challenges your basic intuitions that you've built up from everyday experience. It says your experience of time is not what you think it…

— Brian Greene

Why is there space rather than no space? Why is space three-dimensional? Why is space big? We have a lot of room to move…
