00:00Why did Thanos actually destroy the Infinity Stones?
00:02Well, this is because after he got all of the stones and successfully did the Snap,
00:06he could have used the Time Stone to look into the future, like Doctor Strange did in Infinity War.
00:10And since we know from the Ancient One that a person can't see past their own death,
00:13Thanos only saw up until the moment where the Avengers go to his planet to reverse the Snap.
00:16But since at that point, the Stones are gone, they don't have any way to reverse it.
00:20So Thanos doesn't have any knowledge of the time travel that the team does
00:23and assumes that the Snap is permanent after he destroys the Stones.
