B Are inflatons the same as fewer gravitons?

  1. Dec 12, 2016 #1
    I'm not very conversant in the subject. But it is my impression that the acceleration of the expansion of the observable universe has generated a theory that there might be a new particle (field?) call the inflaton. On the other hand, I thought I'd heard that scientists were trying to find evidence of gravity leaking off into an heretofore unobserved part of the universe. Wouldn't gravity leaking off have the same effect as inflatons (that is to say accelerate the expansion)? Thanks

    No. Inflation in the very early universe and accelerated expansion in the last few billions of years are different things. They might have some deeper, unknown connection, but they are still at completely different scales.
    Extra dimensions, maybe, if they are exist. That is very speculative.
    No.
