Better Quote by Lisa Randall

Some physicists describe gravity in terms of ten dimensions all curled up. But those aren't real words-just placeholders, used to refer to parts of…

— Scott Adams

On the other hand, we don't understand the theory too completely, and because of this fuzziness of spacetime, the very concept of spacetime and…

— Edward Witten

Einstein comes along and says, space and time can warp and curve, that's what gravity is. Now string theory comes along and says, yes,…

— Brian Greene

“In 1914, a Finnish physicist named Gunnar Nordstrom found that all you had to do to unify gravity with electromagnetism was increase the dimensions…

— Lee Smolin

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

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…

— Leonard Susskind

By dimension, we simply mean an independent direction in which, in principle, you can move; in which motion can take place. In an everyday…

— Brian Greene

“Bodies influence the space that surrounds them; they tell us whatever we can learn about that space. Does this mean that, possibly, there is…

— Henning Genz

In the context of general relativity, space almost is a substance. It can bend and twist and stretch, and probably the best way to…

— Alan Guth

Gravity is a response to geometry.

— Albert Einstein

I often think that we are like the carp swimming contentedly in that pond. We live out our lives in our own "pond," confident…

— Michio Kaku

Technically you need the extra dimensions. At first people didn't like them too much, but they've got a big benefit, which is that the…
