Brian Greene Quotes
-
We're on this planet for the briefest of moments in cosmic terms, and I want to spend that time thinking about what I consider the deepest questions.
-
Intelligence is the ability to take in information from the world and to find patterns in that information that allow you to organize your perceptions and understand the external world.
-
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 is, that time is malleable. Your experience of space is not what you think it is; it can stretch and shrink.
-
There was a time when 'universe' meant 'all there is.' Everything. The whole shebang. The notion of more than one universe, more than one everything, would seemingly be a contradiction in terms.
-
There's no way that scientists can ever rule out religion, or even have anything significant to say about the abstract idea of a divine creator.
-
Black holes, we all know, are these regions where if an object falls in, it can't get out, but the puzzle that many struggled with over the decades is, what happens to the information that an object contains when it falls into a black hole. Is it simply lost?
-
Black holes provide theoreticians with an important theoretical laboratory to test ideas. Conditions within a black hole are so extreme, that by analyzing aspects of black holes we see space and time in an exotic environment, one that has shed important, and sometimes perplexing, new light on their fundamental nature.
-
Science is a self-correcting discipline that can, in subsequent generations, show that previous ideas were not correct.
-
The funny thing is, I sometimes get the impression that some people outside of the field think that there's some element of security that we have in working on a theory that hasn't made any predictions that can be proven false. In a sense, we're working on something unfalsifiable.
-
We might be the holographic image of a two-dimensional structure.
-
The pinpoints of starlight we see with the naked eye are photons that have been streaming toward us for a few years or a few thousand.
-
You almost can't avoid having some version of the multiverse in your studies if you push deeply enough in the mathematical descriptions of the physical universe.
-
How can a speck of a universe be physically identical to the great expanse we view in the heavens above?
-
Physics grapples with the largest questions the universe presents. 'Where did the totality of reality come from?' 'Did time have a beginning?'
-
I do feel strongly that string theory is our best hope for making progress at unifying gravity and quantum mechanics.
-
The bottom line is that time travel is allowed by the laws of physics.
-
If the theory turns out to be right, that will be tremendously thick and tasty icing on the cake.
-
The absolute worst thing that you ever can do, in my opinion, in bringing science to the general public, is be condescending or judgmental. It is so opposite to the way science needs to be brought forth.
-
The melded nature of space and time is intimately woven with properties of light speed. The inviolable nature of the speed of light is actually, in Einstein's hands, talking about the inviolable nature of cause and effect.
-
String theory is not the only theory that can accommodate extra dimensions, but it certainly is the one that really demands and requires it.
-
I would say in one sentence my goal is to at least be part of the journey to find the unified theory that Einstein himself was really the first to look for. He didn't find it, but we think we're hot on the trail.
-
The idea that there could be other universes out there is really one that stretches the mind in a great way.
-
I enjoy reading blogs, but am not interested in having my spurious thoughts out there.
-
String theory envisions a multiverse in which our universe is one slice of bread in a big cosmic loaf. The other slices would be displaced from ours in some extra dimension of space.
