Abstract Quote by Scott Adams

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…

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,…

Gravity is a response to geometry.

— Albert Einstein

“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

“For string theory to make sense, the universe should have nine spacial dimensions and one time dimension, for a total of ten dimensions.”

— Brian Greene

“Extending Polyakov's argument, he found evidence that the string theory describing those emergent strings is actually a ten-dimensional supersymmetric string theory. Of the nine…

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

“There are really four dimensions, three which we call the three planes of Space, and a fourth, Time. There is, however, a tendency to…

— H.G. Wells

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…

— Edward Witten

I can't keep from fooling around with our irrefutable certainties. It is, for example, a pleasure knowingly to mix up two and three dimensionalities,…

— M. C. Escher

It's the gravity that shapes the large scale structure of the universe, even though it is the weakest of four categories of forces

— Stephen Hawking

The whole idea of gravity curling up space, that is the epitome of what is going on in a black hole. I would've loved…
