Black Hole Harmonics

Learn more at

Black holes are crazy enough on their own – but crash two together and you end up with a roiling blob of inescapable space that vibrates like a beaten drum. And the rich harmonics of those vibrations, seen through gravitational waves, could hold the secrets to the nature of the fabric of spacetime itself. Today on space time journal club we’ll explore the papers that claim to have detected black hole harmonics. We’ll also give you the latest updates on the most recent – in some cases quite bizarre - LIGO detections.

When physicists talk about black holes they’re usually referring to highly theoretical objects – static, unchanging black holes viewed from “infinitely” far away. This makes everything clean and simple enough to attempt the already notoriously complex calculations of black hole physics. But real black holes are created in the violent deaths of massive stars, and there’s nothing clean about that. And we now know that black holes merge – and in the process produce gravitational radiation that we’ve only just managed to detect with the miraculous work of the LIGO and VIRGO gravitational wave observatories. In the instant after its merger, the new, joined black hole looks nothing like the idealized theoretical black hole.

I guess a friendly warning does not work with you.

All your videos are the copycats which you downloaded from the Youtube and stole from dozens of various accounts, these are not your own work, you can not use #neoxian tag for this, the Neoxian.City only accepts the ORIGINAL content.

When posting content that either is owned by someone else or inspired by someone else’s works, it is proper to list the said source in your post with a link to the original.

Failing to do so is considered plagiarism, and could result in being blacklisted by curation groups or even flagged.

Examples include:

  • Using another artist's original drawing/painting/digital art as a “study” or inspiration without linking the original and giving credit to the original artist.
    • Linking to someone else’s YouTube video with no source.
    • Using someone else’s photos or text without linking to the original source etc.
Please make sure you do so in the future, thank you.

If you understand the rules explained in this comment reply to this comment with "I understand"
