Lisa Randall
Lisa Randallis an American theoretical physicist and an expert on particle physics and cosmology. She is the Frank B. Baird, Jr. Professor of Science on the physics faculty of Harvard University. Her research includes elementary particles and fundamental forces and she has developed and studied a wide variety of models, the most recent involving extra dimensions of space. She has advanced the understanding and testing of the Standard Model, supersymmetry, possible solutions to the hierarchy problem concerning the relative weakness...

Maybe dark matter is denser than we usually assume, kind of like the Milky Way plane.
There are many aspects of time we just do not understand. That's the thing about writing a popular book: You realize the things you understand because for those you can give a really simple explanation. But some things about time I just don't know how to give simple explanations for, even though I can tell you mathematically what's going on.
There is real confusion about what it means to be right and wrong - the difference between what spiritual beliefs are and what science is.
When people try to use religion to address the natural world, science pushes back on it, and religion has to accommodate the results. Beliefs can be permanent, but beliefs can also be flexible. Personally, if I find out my belief is wrong, I change my mind. I think that's a good way to live.
Scientific research involves going beyond the well-trodden and well-tested ideas and theories that form the core of scientific knowledge. During the time scientists are working things out, some results will be right, and others will be wrong. Over time, the right results will emerge.
The universe has its secrets. Extra dimensions of space might be one of them. If so, the universe has been hiding those dimensions, protecting them, keeping them coyly under wraps. From a casual glance, you would never suspect a thing.
All the normal matter in the Milky Way disc is denser than the dark matter that surrounds it...
Probably if you look like Tyra Banks, it probably is hard, even if you are really smart, for people to take - it surprises some.
One of the nice things about math and science is it's obvious, you get the answer or you don't get the answer.
An almost indispensable skill for any creative person is the ability to pose the right questions. Creative people identify promising, exciting, and, most important, accessible routes to progress - and eventually formulate the questions correctly.
I did not set out to explain the extinction of the dinosaurs. I'm a particle physicist, and I was actually thinking about dark matter along with some collaborators.
Travel at faster than the speed of light certainly can have dramatic implications that are difficult to understand, such as time travel.
If such external influences are intrinsic to religion, then logic and scientific thought dictate that there must be a mechanism by which this influence is transmitted. A religious or spiritual belief that involves an invisible undetectable force that nonetheless influences human actions and behavior or that of the world itself produces a situation in which a believer has no choice but to have faith and abandon logic--or simply not care.
Sometimes models are surprisingly smart.
