However, the simplest as to why he didn't: Sauron had no way of locating his
Sauron is not able to detect it wherever it is. The Ring compels its bearer to use it in the presence of Sauron's allies but Sauron was actually only able to detect its use twice - once at Amon Hen (at Seat of Seeing) and once when Frodo claimed it for his own in Mordor.
As it turns out, even after forging the One Ring, Sauron was still capable of feeling fear and regret. Actually, even during the War of the Ring and at the height of his power.
Bilbo found the ring 60 years before the events of The Lord of the Rings. At the time, Sauron was the Necromancer, in Dol Gulder. He doesn't even know the ring has been found, until Gollum is brought to Mordor. Sauron was less powerful in The Hobbit, which is the reason why he didn't find Sméagol when he became Gollum.
As far as we know, Sauron cannot detect the presence of the Ring, or even someone putting the Ring on. He only becomes aware of someone if they put it on and claim it as their own possession, while they are relatively close to him.
As for Sam, his resistance likely has to do with his innate goodness and loyalty. His love for Frodo helped him to overcome the pull of the Ring and his inner pureness was never fully pierced by the Ring.
The first is that Bilbo is a hobbit, and as such, is particularly difficult to manipulate or corrupt. Hobbits have a natural resistance to the influence of the ring, because they are fully content in their simple lives and have no desires for power or war.
The Ring only affects mortal beings, and because Sauron is an immortal Maia spirit, he doesn't experience the same side effect of invisibility.
Galadriel Was Ashamed Sauron Tricked Her
The fact that she had saved his life, become his friend, and potentially even developed a little bit of a crush might have just been too shameful for Galadriel to share immediately. There could have also been a darker reason that Galadriel didn't want to confess the deception.
Sauron Thought Frodo Was Just a Spy
However, when the Mouth of Sauron speaks to Aragorn, he describes Frodo as a "spy from the little rat-land of the Shire." Meaning they thought he was nothing more than a scout for Aragorn.
After the War of Wrath, with the downfall of Morgoth and the destruction of Thangorodrim, Sauron adopted a fair form and repented his evil deeds in fear of the wrath of the Valar.
In The Lord of the Rings, it is said that had Galadriel chosen to use her powers for evil instead of good, she would have been even more destructive and terrifying than Sauron himself. Galadriel was the greatest and most powerful of all Elves in Middle Earth in the Third Age.
Sauron was the most powerful of the Maiar—primordial spirits created to help the Valar first shape the World. His original name was Mairon, which means "the Admirable," and as an immortal spirit born before the world's creation, he was able to perceive the Creator Eru Ilúvatar directly.
While the previous 19 rings were crafted with the help of the Elves, the final ring, the 'One Ring to rule them all,' was crafted by Sauron alone; with the ability to dominate the other rings, the One Ring was made with some of Sauron's own power, in order to make it more powerful.
Sauron intended it to be the most powerful of all Rings, able to rule and control those who wore the others. Since the other Rings were powerful on their own, Sauron was obliged to place much of his own power into the One to achieve his purpose. Creating the Ring simultaneously strengthened and weakened Sauron.
Sauron's deepest fear was that Aragorn would use the Ring against him. With its powers of domination, Aragorn could comfortably take over the entirety of Sauron's dark army. Though this would eventually corrupt Aragorn, it would allow him to destroy Sauron and take his place.
Though Galadriel doesn't share her news, Elrond is suspicious and wanders out to find the genealogy scroll that leads him to figure out that Halbrand is Sauron. Unfortunately, he finds this news too late, arriving back at the workshop just as the elven rings (the rings of power) are being completed.
No, Sauron did not love Galadriel in The Rings of Power, despite the evil entity's offer to make her his queen. In Tolkien lore, Sauron is notorious for disliking elves and the Children of Eru, therefore, his affection for Galadriel would not align with the source material.
The Dark Lord easily overpowers her, and after Galadriel rejects his proposal to join him, he traps her in illusions and leaves her to drown in the water.
After much speculation and enough fan theories to fill a dwarven mine, “Rings of Power” fans finally got their answer on Sauron's true identity in the prequel series — and it's Halbrand (Charlie Vickers).
The theme of addiction to power in The Lord of the Rings is central, as the Ring, made by the Dark Lord Sauron to enable him to take over the whole of Middle-earth, progressively corrupts the mind of its owner to use the Ring for evil.
The Ring's power was its greatest at Mt Doom. According to Tolkien, Frodo at this point had grown in spirit strong enough the Nazgul would be unable to lay a finger on him with the ring.
It's a constant reminder to Aragorn of his family history; his hesitation to take the ring from Frodo Baggins (Elijah Wood) is a direct result of Isildur's corruption. Although Boromir ultimately falls victim to the seductive nature of the ring, Aragorn is able to defy his family history and resist his urges.
Because of their intense love of the earth, the Ring does not sense hobbits as a threat, which is why they were able to be overlooked and complete the quest.
The Fellowship can't ride eagles to Mordor because of the giant, flying snake-dragon monsters ridden by One-Ring-sensing warrior kings and their half-mile-wide aura of fear.
