 How in the world were the great pyramids of Egypt built? These massive structures are believed to have been built more than 4500 years ago. It turns out those ancient Egyptians understood the power of vibrations and frequencies. So, everything around us, from the tiniest atoms to the vast galaxies, is vibrating. And the Egyptians knew this secret of the universe inside out. They believed that by tapping into the universe's frequencies, they could do amazing stuff like healing, communicate, even bend the physical world to their will. And those pyramids are not just piles of stones, they're masterpieces of vibrational engineering. But how exactly did they build these massive structures? Some researchers today think the Egyptians were all about using sound. They may have used sound waves to vibrate the stone, making it easier to move. They may have also used sound waves to cut and shape the stone, as well as to levitate it into place. That is actually how powerful sound can be when you know how to harness it.
