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. Leonard Susskind Read Quote
The dark energy is not exactly zero, but the first 122 decimal points are zero. That’s crazy. That is really one of the craziest things we’ve ever discovered. Leonard Susskind Read Quote
You are a victim of your own neural architecture which doesn’t permit you to imagine anything outside of three dimensions. Even two dimensions. People know they can’t visualise four or five dimensions, but they think they can close their eyes and see two dimensions. But they can’t. Leonard Susskind Read Quote
The most important single thing about string theory is that it’s a highly mathematical theory, and the mathematics holds together in a very tight and consistent way. It contains in its basic structure both quantum mechanics and the theory of gravity. That’s big news. Leonard Susskind Read Quote
Whether or not evolution is compatible with faith, science and religion represent two extremely different worldviews, which, if they coexist at all, do so most uncomfortably. Leonard Susskind Read Quote
I often feel a discomfort, a kind of embarrassment, when I explain elementary-particle physics to laypeople. It all seems so arbitrary – the ridiculous collection of fundamental particles, the lack of pattern to their masses. Leonard Susskind Read Quote
Space can vibrate, space can fluctuate, space can be quantum mechanical, but what the devil is it? And, you know, everybody has their own idea about what it is, but there’s no coherent final consensus on why there is space. Leonard Susskind Read Quote
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. Leonard Susskind Read Quote
Eventually, when the universe expands enough, all that will be left is the dark energy. Leonard Susskind Read Quote
Every time a bit of information is erased, we know it doesn’t disappear. It goes out into the environment. It may be horribly scrambled and confused, but it never really gets lost. It’s just converted into a different form. Leonard Susskind Read Quote
