    Captain Marvel Did What She Said She Would Do

    From Redditor u/TheReplacer:

    So, I watched Captain Marvel last night and then went back to re-watching Guardians of the Galaxy. I had theory I want to prove and now what happen in Guardians of the Galaxy makes so much more sense than we first realized. Now in Guardians of the Galaxy we see the Nova Empire and the Kree Empire have signed a peace treaty. But why now all of a sudden after a thousand years of war. It always struck me as odd why this peace treaty happens in the first place and why it happens. But now I think it happen because Captain Marvel destroyed the Supreme Intelligence.

    Remember when she sends Yon-Rogg back to Hala with the message that she will destroy the Supreme Intelligence and end the war. Well she kept her word because the Kree and Nova Empires are no longer at war. She of course knew the only way to end the war was to destroy the Supreme Intelligence. Because everything the Kree do is because the Supreme Intelligence says it needs to be done for the betterment of the Kree race. She knows that the Kree are in a pretty helpless situation with their Super AI warmind gone. The Kree then would no longer have the Supreme Intelligence to guide them. Meaning they are leaderless and would not really know what to do in that situation since it never happened before. Now they’re not stupid but losing the Supreme Intelligence would leave them at a big disadvantage and no clear indication on what to do next. So, in a form of panic they called for peace so they would not be wipeout right away by all the enemies they made over the years.

    Also, it would explain why Ronan became rogue and went to Thanos for leadership. Because with the Supreme Intelligence destroyed, he would be in a leaderless state. He also found the Krees' reaction of forming peace right away as weak and would have probably want them to keep fighting without the Supreme Intelligence. Also explains why Ronan suddenly realized after he had an infinity stone, he no longer need Thanos help to wipeout Xandar. He had seen how powerful Captain Marvel had been when she had some infinity stone power and he had a real stone in his possession.

    So, Captain Marvel saying she is going to destroy the Supreme Intelligence fits pretty well with us watching the aftermath of that event in Guardians of the Galaxy.

    Carol Hasn't Helped More Because The Pager Takes Too Long To Reach Her

    From Redditor u/Praeger:

    TL/DR - the pager takes weeks to months for the signal to get to Captain Marvel. This explains why she hasn't turned up in past movies.

    So in the after credits spoiler we get to see that the 'beacon' has been on for a little while now, we can easily assume weeks to months based upon a few factors: 1 - they first had to track the pager down 2 - they had to build a beacon amplifier around the pager 3 - the battery has 'at long last' drained

    So let's assume a minimum of 2 weeks, and up to a few months. Ok - so now let's assume that Fury actually did use the beacon twice in the past - firstly when NY is invaded, secondly with Ultron. NY - this went down over a period of days. Even if Fury hit the beacon the instant Loki arrived (which I think is logical considering the space stone connection to Marvel) she still would have arrived too late. Ultron - this has two possible answers. I don't know exactly how long they've said it went for, but from the movie it appears anywhere from a week to two weeks - so again either Fury did call, and she arrived late, or maybe Fury messed this one up and assumed that if the avengers could defend against one invasion, they could deal with a robot and decided not to call her.

    Either way it leads to a world wide alien invasion in infinity war, and as soon as he hears about it and sees the devastation going on, he immediately runs to the pager - but even if he'd pressed or hours ago, Captain Marvel still wouldn't have arrived in time.

    Captain Marvel Caused The Phoenix Lights

    From Redditor u/Captaindeadpool172:

    Just thought about it during the rewatch of Civil War. When Tony first meets Peter he shows videos of Spiderman saving people, but Peter says the videos are fake and Tony says "like UFOs over Phoenix." That confirms the 'Phoenix Lights' happened in the MCU universe. The 'Phoenix Lights' happened during 1997 and Captain Marvel is set in the '90s - what if the Phoenix Lights were Kree-Skrull war happening in the MCU universe?

    S.H.I.E.L.D's Intel Is Due To The Skrulls

    From Redditor u/rgtxd26:

    At the end of Captain Marvel, Carol sets out to find a home for Skrull far away from the reach Kree. I think that after a lot of search, Carol finds that the only place in the Universe where the Skrulls are safe from the Kree is Earth. The Kree are afraid to come to Earth after they've seen what happened to their ships in Captain Marvel. The Skrulls set up their base just outside the Earth with the help of Nick Fury who is now the director of SHIELD. But Carol sets out to help the other planets. Nick Fury used the help of Skrulls' alien technology to upgrade SHIELD's intel and get their eyes on everything that's happening on Earth. The map that's shown in Iron Man 2, which shows many places including Wakanda, is the result of the Skrulls' technology.

    SHIELD used its technology to find all the heroes and location of Captain America in the ice . He kept it a secret from all others in SHIELD and even Carol. The words of Tony Stark in Avengers, "Fury's secrets have secrets,"are proven to be true. After SHIELD had ended in CA:TWS, he went to the Skrulls' base and took cover until AOU. He uses the help of Skrulls to bring the helicarrier to Sokovia. He tells that he brought it with the help of some 'old friends' and secretly referring to the Skrulls. In Infinity War, Talos too died from the Snap and when he was revived, they found that they had no intel and the Earth is now the center of cosmic events and without the Avengers, it lacked protection. At the start of FFH, Talos tells Soren that they have no intel after events of Endgame. There are no one listening to them so they don't have to pretend as Fury and Hill. This means that maybe he was referring to the Skrulls' radar which has weakened during those five years. Then, Talos replaced Nick Fury on Earth and Fury was helping the Skrulls to set up the protection of Earth.
