The word 'universe' is obviously not intended to have a plural, but science has evolved in such a way that we need a plural noun for something similar to what we ordinarily call our universe.

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 are with us to stay, and they entered physics a long time ago. They are not going to go away.
Interpretation
What this quote means
Extra dimensions are a legitimate aspect of physics, often dismissed as speculative, but they have been part of scientific discourse for a long time.
This quote by Leonard Susskind emphasizes the important role that extra-dimensional theories play in the field of physics, arguing against the common perception that they are purely speculative or fictional. He asserts that these theories are integral to understanding the universe and have been established within the scientific framework for some time, suggesting that they are not fleeting ideas but rather vital components that will remain in scientific discussions.

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 around in. How come it's not tiny? We have no consensus about these things. We're still exploring them.

Let's get into talking about how autism is similar animal behavior. The thing is I don't think in a language, and animals don't think in a language. It's sensory based thinking, thinking in pictures, thinking in smells, thinking in touches. It's putting these sensory based memories into categories.

Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not contradict the theory.

Medicine is a social science, and politics is nothing else but medicine on a large scale. Medicine, as a social science, as the science of human beings, has the obligation to point out problems and to attempt their theoretical solution: the politician, the practical anthropologist, must find the means for their actual solution. The physicians are the natural attorneys of the poor, and social problems fall to a large extent within their jurisdiction.

When you start in science, you are brainwashed into believing how careful you must be, and how difficult it is to discover things. There's something that might be called the 'graduate student syndrome'; graduate students hardly believe they can make a discovery.

Our task now is to resynthesize biology; put the organism back into its environment; connect it again to its evolutionary past; and let us feel that complex flow that is organism, evolution, and environment united. The time has come for biology to enter the nonlinear world.
