The cosmological constant is introduced in Einstein equations in the form : $G_{\mu\nu} = T_{\mu\nu} + \Lambda g_{\mu\nu}$, as I understand it, shouldn't the term $\Lambda g_{\mu\nu}$ have effects on time and not just space (causing expansion)?

    $\begingroup$ Are you asking if it makes time expand? $\endgroup$ – HDE 226868 Dec 13 '14 at 22:14
  • $\begingroup$ For instance, yes. $\endgroup$ – yau Dec 13 '14 at 22:19
  • $\begingroup$ You say, "for instance" to the above question, does this mean to imply that you have other effects of $\Lambda$ in mind? If so, please add them to the question. $\endgroup$ – Kyle Kanos Dec 14 '14 at 3:29
  • $\begingroup$ No i don't have others effects in mind, but i'm not sure that expansion would be the only one. $\endgroup$ – yau Dec 14 '14 at 15:01

Yes, it will expand spacetime, thus time is also included

    $\begingroup$ Could you expand on this a little bit? $\endgroup$ – Kyle Kanos Dec 14 '14 at 2:16
