Gravity[edit]

It says in the article that the four fundamental forces were unfied during the GU epoch. I thought gravity had separated at the end of the Planck era, and the remaining 3 were still unified until the storng force split off at the end of the GU. I'll look into this further and will change article if need be.24.21.139.41 13:26, 14 May 2007 (UTC)[reply]

If gravity had separated, how can one say that mass was meaningless during this period? — Preceding unsigned comment added by 70.145.142.201 (talk) 09:51, 14 August 2008 (UTC)[reply]

Exactly the same question occurred to me. Can someone please answer? Winston (talk) 17:02, 20 October 2023 (UTC)[reply]

Hypothetical[edit]

This article does not emphasize enough that grand unification and the grand unification epoch are relatively speculative hypotheses Aknochel (talk) 10:23, 13 May 2014 (UTC)[reply]
