Why was the Trojan war said to shake both heaven and earth?

The Trojan War was said to shake both heaven and earth due to the magnitude of the conflict involving powerful gods and goddesses intervening in mortal affairs. The involvement of deities such as Zeus, Athena, and Aphrodite in supporting different sides of the war added a divine dimension to the already intense human conflict. The epic battles, tragic losses, and legendary heroes on both sides further contributed to the belief that the war had profound impacts beyond the mortal realm, resonating throughout the heavens and the earth.
