Who broke the Bifrost?

Good day, fellow enthusiasts! I have a burning question that's been nagging at me ever since I delved deeper into the world of Norse mythology. It's a question that has puzzled scholars and fans alike for centuries: Who, exactly, broke the Bifrost? This celestial bridge, connecting Asgard, the realm of the gods, to Midgard, our human world, is said to be immensely strong and resilient. Yet, according to some tales, it was shattered at one point. So, I pose the question once more: Who had the power and the motive to break such a formidable structure? Was it a jealous rival god, a mischievous trickster, or perhaps a mighty giant seeking to challenge the gods' authority? Let's delve deeper into this enigmatic tale and try to uncover the truth behind this enigmatic event.
