I googled Planck but the satellite is not equipped with GW detectors. You should have LISA but its funding is risky, to say the least. So earth-based detectors must bear the burden. Are they capable?

I googled Planck but the satellite is not equipped with GW detectors.
Don't know a lot about it yet, but I've read that polarization measurements of the CMB anisotropies 'may also detect the signature of a stochastic background of gravitational waves generated during inflation, 10^(-35) second after the Big Bang.' Still not like directly detecting the waves, though...

I am always confused when I read of times spanning a trillionth of a second at the instant of the Big Bang. But should not time slow down in the vicinity of a huge mass and a still greater density?

Yes, it's hard to see how things got their start (based on the way things appear now) without considering an inflationary epoch...

From what I understand, "classical" general relativity is not sufficient to treat the inflationary model of the universe. You have to throw in elementary particle physics, that is quantum mechanics and group theory, plus quantum gravity. What you need is a "Theory of Everything". Good luck!.
