[Cosmo-torun] proof for gravitational waves?

[Tomasz Kazimierczak]

Hi all,

Hot news in media, according to which there is
detection of gravitational waves by the BICEP2 experiment.
It is something about messuring b-mode polarisation of CMB,
that's all what I undersdand.

Can we say it is a direct evidence for gravitational waves or rather
it should be said indirect?


Pozdr,
