What do you think are the odds that dark matter and dark energy (as concepts) are a result of us not fully understanding how gravity works? Einstein improved on Newton’s theories, so what’s the likelihood of someone coming along and improving (extending, really, since they’ve been proven) on Einstein’s theories?

Of course, it’s unknowable, but do you suspect we have a lot more to learn about gravity?

Dr. Filippenko,

I love the Understanding the Universe series you did for The Teaching Company/The Great Courses. Do you plan on making any more courses like that in the near future? Thanks!
