This Object Exists. Scientist Don't Know How.

Something is threaded through the universe. It has been there since the first moment of time. We cannot see it. We cannot touch it. But we may have just heard it. Cosmic strings are theoretical structures left over from the Big Bang — impossibly thin, incomprehensibly dense, potentially stretching across the entire observable universe. A single meter of one would outweigh the Earth. And they may be passing through you right now. In this video, we explore one of the deepest unsolved mysteries in modern physics: the search for the oldest objects that could exist. From the phase transitions of the first fraction of the first second, to the 2023 pulsar timing array discovery that may have detected their gravitational hum for the first time — this is the full story of cosmic strings. Settle in. This one goes deep. Topics covered in this video: What cosmic strings are and how they formed Why they are invisible to every telescope we have built The gravitational lensing signature we have been searching for The 2023 pulsar timing array results and what they detected What it would mean if the oldest objects in the universe are real The instruments being built right now to find them Late Space — long-form space documentaries for sleep and deep thinking #space #cosmicstrings #universe #bigbang #astrophysics #sleepmusic #spacedocumentary #gravitationalwaves #darkuniverse #latespace
