When Obi-Wan tries to go into the security recordings in the Jedi Temple after he and Yoda reset the beacon, Yoda warns him not to. But without that footage, Obi-Wan would not have known that Anakin had turned to the Dark Side and led the attack against the Temple. If Obi-Wan had listened to Yoda and not looked at the security recordings, what would have happened. Did Yoda already know that Anakin had betrayed them? For that matter, how did Yoda and Obi-Wan even know that Palpatine was Darth Sidious? Mace doesn't seem to have told anyone before he heads to confront Palpatine.
Yoda is powerful enough in the force to feel Anakins turn to the darkside. With this the mask Palpatine put up to protect himself wasn't needed. So he likely knew through the force just because the darkside was so strong at that point.
I think Yoda knew when he was with the Wookies. Once Yoda came back to Corascent, he reached out to Bail and Bail told Yoda and Obi Wan they were branded as traitors. Padme knew where Anakin was, but did Obi Wan know the Separatist leadership was there?
If Yoda could sense Anakin's pain and anger after Shmi died in AotC, I'm sure he could feel what happened in RotS. Going back to the Temple and seeing Jedi killed with a lightsaber would probably have confirmed his suspicions.
Yoda reacts just after Anakin has turned and is christened as Darth Vader. He felt a great disturbance in the Force and when he sees that some of the Padawans were killed with a Lightsaber, he realizes that it couldn't have been Darth Sidious. That left one other person.
I don't think it had anything to do with Yoda's "Force sense." In the ROTS novelization, Mace Windu confers with Yoda before going to arrest Palpatine, which may be "non-canon" now but we can assume it was the way things occurred because unlike all the other Jedi who are caught unwittingly Yoda is able to predict Order 66. I think in that scene it is insinuated that Yoda has already watched the security tapes before since he knows that Obi-Wan will feel heartbreak if he watches it. Finally, they knew Palpatine's Sith name because Dooku told Obi-Wan in AOTC that "the Senate was under the control of a Sith Lord called Darth Sidious." Even if you don't take into account the EU and the fact that they have been tracking Sidious for months, he simply put two and two together; the Sith Lord controlling the Senate of course had been the Senator who was controlling the Senate. In regards to Yoda not wanting Obi-Wan to know, I don't know what his motivation was there, was he planning to destroy the Sith himself? How would he have used Obi-Wan if he had no revealed Vader's identity. That left one other person? At this point there are hundreds if not thousands of other Jedi, let alone cyborgs and bounty hunters that use lightsabers. I thought it had seemed that Yoda was simply feeling the shift in the Force as the dark side had gained momentum. Him being able to track Anakin's actions from across the galaxy seems..unlikely.
I see what you're saying. When Yoda feels the disturbance in the Force as Sidious christens Anakin, he can tell that Anakin has fallen to the Dark Side. However I'm not sure how Yoda saw the lightsaber wounds on the Padawans and knew that it wasn't Darth Sidious. For all he knew, Sidious could have come to the Temple personally and killed the Jedi alongside the clones. A lightsaber wound doesn't confirm that Anakin was the killer.
Yoda knew deep down that it was Anakin, because he was the only one who was giving off warning signs that he could betray the Jedi. Sidious has been a behind the scenes player. He hasn't been out there like Dooku was, nor Maul. Maul and Ventress were out of the picture. Dooku and Grievous were dead. Sidious wouldn't put himself at risk. That's why he runs when Yoda goes to confront him and only fights when Yoda blocks his way.
I don't think Yoda knew with 100% certainty, but he had a pretty good suspicion it was Anakin. And as far as his comment to Obi-Wan, it was more to warn Obi-Wan that he may not like what he's going to see. Not necessarily Yoda already knowing that it was Anakin behind the slaughter of younglings.
That makes a lot of sense, actually. It's a good point about Sidious being a behind the scenes person and Anakin being the only Jedi who might betray the Jedi.
Nothing about the scene implies that Yoda knew it was Anakin. And since you go by the "official canon" you are aware of Jedi like Krell who could also be seduced to the dark side, by your own "official canon" that line of thought makes little sense. But your opinion is your own, I'm sure it's a popular one. Your right in saying Sidious was a behind the scenes player, I think Yoda knew it was out of character for the guy who had been hidden for the last decade to reveal himself and start fighting on the front lines.
Then why would Yoda try to stop Obi-wan from looking at the hologram footage as if Yoda already knew what Obi-wan was about to see? By telling him, "If into the security recordings you go, only pain will you find", that tells us that Yoda already knew that Anakin helped the empire attack the Jedi temple. He knew that Anakin had turned to the dark side from the moment he felt a great disturbance in the force on Kashyyk which occurred right after Mace Windu was killed. Yoda also knows how close Anakin is to PalpSidious when he saw how upset Anakin gets when the Jedi show disrespect to the chancellor which gives Yoda another indication of Anakin's betrayal.
I'm talking about the scene on Kashyyk when Yoda stumbles. It is after the death of Windu and the crowning of a new Sith Lord, there has been a shift of the Force in favour of the dark side. Nothing in that scene implies Yoda knew it was Anakin. He doesn't say "young Skywalker blah blah blah" like he did in AOTC. It's left for the viewer to interpret. Obviously in the temple he knows it was Anakin, because (I think it's implied) he has watched the tapes while Obi-Wan was changing the signal. For those of you who think Yoda sensed that it was specifically Anakin who had fallen to the dark side, answer me this, if that is so why didn't Yoda sense when Dooku, who according to "official canon" (which I consider bull$%*# btw but am sick of being told about) was his padawan?? Yoda had trained Dooku and known him his entire life, while he had only sparingly known Anakin for 13 years by the time of ROTS. Doesn't make sense.
Yoda said "Fought well you have, my old Padawan" in AoTC - that's probably why other sources end up being ignored. Why didn't he sense Dooku's Fall? That's an interesting question. Maybe when Palpatine was luring Dooku to the Dark Side he was "shielding" him somehow, until Dooku could do it himself. Result - Mace Windu cannot believe it's in Dooku's character to commit murder, in AoTC.
If Palpatine can shield Dooku why would wouldn't he be able to shield Anakin. Could it instead be Yoda was sensing the death of half the Jedi Council?
How can Yoda not know that Anakin has turned traitor by then?? He knows that Anakin is loyal to PalpSidious and he agreed with Mace when he said that it was too dangerous to have Anakin spy on PalpSidious. Sensing the whole "shift of the Force" should've been enough to tell Yoda that their little spy plan has backfired so if Yoda can sense Anakin slaughtering the Tusken Raiders, then he can sense him turning to the dark side. Another thing, there's no indication that Yoda had already watched the hologram footage before he tried to stop Obi-wan from doing the same. The scene shows us Yoda already looking at Obi-wan as he's changing the signal and he's too far away from the computer to watch the footage. First, either Dooku isn't as powerful in the force as Anakin was or PalpSidious taught him how to shield himself from the Jedi. Second, Yoda has trained millions of Jedi throughout his 8-centuries career before he came upon Dooku. Even if Yoda had known Dooku his whole life, it doesn't mean he can sense the dark side in him until he's actively using it. You've just answered your own question. At that point, there was no reason for PalpSidious to shield Anakin from the Jedi now that they're being killed off.
The novelization went with "Yoda senses Anakin is in terrible pain" (emotionally) but no more than that. The EU took a similar approach - with the idea being that Anakin would have "faced disgrace" if he'd told the whole truth about what he did.
The movie shows Yoda hearing both loud screaming and the ghost of Qui-Gon yelling for Anakin to stop. That shows us that Yoda sensed more than just Anakin's pain.
If Yoda sensed what Anakin had done why wasn't he removed from the Jedi Order? Yoda says the spy plan was too dangerous...but he certainly gave it the OK... How could Palpatine have taught Dooku to shield himself before he turned him to the dark side.. You're really pulling at straws here. Palpatine has reason to shield Anakin from the Jedi because Order 66 has not been initialized yet, and Yoda's foreknowledge of retaliation is what saves him, if Palpatine can personally block Yoda's Force sense why wouldn't he do so right before attempting a mass killing of the Jedi?? When Yoda enters his office Palpatine seems fairly surprised that he survived. I find your opinion flawed but never-the-less it's your opinion. Yoda being able to sense everything Anakin does just seems inconsistent with the other events in the films.
He was too preoccupied with rescuing Obi-wan on Geonosis and the incoming Clone Wars. Yoda needed every Jedi available to end the war before it escalates including Anakin. Because Yoda figured that Anakin's friendship with Palpatine will help the Jedi get closer to uncovering the identity of Darth Sidious. There was no need for PalpSidious to teach Dooku anything because he still had Darth Maul at the time. But PalpSidious did NOT have a reason to shield Anakin from the Jedi because they have no reason to suspect him of betrayal, especially after Anakin tells them that Palpatine is Sidious. Once that information is out, Mace tells him, "If what you told me is true, then you'll have gained my trust" so at this point, noone in the Jedi Order would believe that Anakin would turn traitor until it's too late and PalpSidious knew this. As you've pointed out, Yoda's foreknowledge of the order 66 attack saved him but he's not on Coruscant to stop PalpSidious from initiating order 66 so there was no reason for PalpSidious to block Yoda's Force sense. Another thing, there's nothing inconsistent about Yoda sensing everything Anakin does because he knew from the beginning that there will be "grave danger" in Anakin's training.
Oh, you changed your mind pretty quick there..Did he or did he not shield Dooku?? Also, the reason for Palpatine blocking Yoda's Force sense would be so he could..kill him in Order 66. It's not a complicated idea. There is something very inconsistent about Yoda sensing everything Anakin does because if he can sense everything Anakin does: Why can't he sense everything Dooku, his former padawan does? Why didn't he sense that Anakin had executed Dooku? Why didn't he sense that Anakin had witnessed the death of his mother? Why didn't he sense that Anakin had committed genocide? Why didn't he sense that Anakin was obsessed with those close to him and couldn't grasp the concept of letting go of these relationships? Why didn't he sense that Anakin was married? Why didn't he sense that Anakin could be redeemed? Seems oddly out of place that Yoda missed all those things if he can Force-sense everything Anakin does, don't ya think? So let me get this right, your thought process is that Yoda said to himself: "So what if this highly unstable padawan, who is incredibly powerful and whose training I sense massive danger in just committed genocide against an entire village, I need troops for my war! Make him a Jedi Knight!" My guess is that is not what happened, what happened is that Yoda felt a surge of Anakin's pain through the Force, not knowing what the root of it was, and after Geonosis and the beginning of the war he simply forgot about it or chalked it up to something war-related.
I do think Yoda knew, yes but I doubt it had anything to do with the Force. I think Yoda cautioned Obi-Wan against watching because he doubted Obi would handle it well. Yoda doesn't sem to trust much of anything beyond himself.
The show is official canon, which I acknowledge. But the difference is that Anakin was already a known concern. Yoda, Mace and Obi-wan just had a conversation about it before Yoda left for Kashyyyk. Krell and Barriss were already secured and the clones would not follow them, given what happened with the two of them. More likely, Yoda felt a disturbance because it was the Chosen One who fell, which also affected the balance of the Force, tipping it completely out of balance.
