🌌Space is completely silent due to its emptiness
🔊Sound requires molecules to travel
🌍Billions of years ago, the universe was filled with hot plasma, allowing sound to propagate
🎙️Sounds transmitted from space are actual sounds decoded by researchers
🌠Space is a vast and empty place
Why is space silent?
—Space is silent because it is virtually empty and lacks the molecules required for sound to travel.
Could sound travel through space in the past?
—Billions of years ago, after the Big Bang, the entire universe was a ball of hot plasma, allowing sound to pass through.
Are the sounds we hear from space real?
—The sounds we hear from space are actual sounds that have been decoded and pitched up for human perception by researchers.
Why is space considered empty?
—Space is considered empty because it contains very few atoms, about 10 atoms per cubic meter, compared to our own atmosphere which has about 10,000,000,000,000,000,000,000,000 atoms per cubic meter.
What is the nature of space?
—Space is vast, empty, and devoid of sound.
