Dark Matter vs. Dark Energy
Scott Dodelson
Fermilab and The University of Chicago
There is abundant evidence for dark matter in the universe. Why even
consider the alternative of modifying gravity? Despite its role as an
underdog, modified gravity has scored a number of successes. Several
recent advances, both theoretical and observational, have given new life
to this old idea. I will try to convince you that the game is not over,
and that the struggle between the two approaches is as exciting as ever.
