The Oldest Sound in the Universe Will Give You Goosebumps!

Did you know the universe has a sound — and it’s billions of years old? After the Big Bang, ripples of pressure waves vibrated through the hot plasma of the early cosmos for around 400,000 years. These were literal sound waves, compressing and expanding matter as the universe expanded. Scientists at NASA and Princeton recreated this ancient hum by converting the cosmic microwave background fluctuations into audible sound. The result? A deep B-flat note, 57 octaves below middle C — far too low for the human ear to hear. This sound represents the first ever cosmic vibration, the echo of creation still resonating through the fabric of space-time today. Is the universe still humming its birth song even now? 👉 Follow for more mind-blowing space mysteries. 📲 Connect with me on Facebook:   / 1altqecff3
