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.
Cosmology is among the oldest subjects to captivate our species. And it’s no wonder. We’re storytellers, and what could be more grand than the story of creation?
But if you think about a practical implication of enriching your life and giving you a sense of being part of a larger cosmos and possibly being able to use this [gravitational waves] as a tool in the future.
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.
We do not know whether there are extra dimensions or multiverse. Let’s go forward with the possible ideas that come out of the mathematics. It’s hard for us to imagine a universe that would have no time at all.
And putting together the probabilities of quantum mechanics with the certainty of general relativity, that’s been the big challenge and that’s why we have been excited about string theory, as it’s one of the only approaches that can put it together.
In the far, far future, essentially all matter will have returned to energy. But because of the enormous expansion of space, this energy will be spread so thinly that it will hardly ever convert back to even the lightest particles of matter.
That is, you can have nothingness, absolute nothingness for maybe a tiny fraction of a second, if a second can be defined in that arena, but then it falls apart into a something and an anti-something. And that something is then what we call the universe.
Science is the greatest of all adventure stories, one that’s been unfolding for thousands of years as we have sought to understand ourselves and our surroundings.
