Hi, I have another doubt ![Big Grin :biggrin: :biggrin:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
In addition to the Supernovae Ia, which more brought us to think the expansion was accelerating? And is there any difference between dark energy and quintessence? Because I've heard that dark energy is like vacuum energy (cosmological constant) and quintessence... I don't really know![Stick Out Tongue :-p :-p](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Thanks for all, since I'm in Physics Forums I've learned lots of healpful thigs!
