I have three types of links attached to my post

  1. Linking to a topic that helps readers learn more but without extracting any information from it. For example, in the first paragraph of this post, I have added links to The moon and the sun. No information was taken from this link.
  2. In this post I have collected some single information and linked it directly to the text.
  3. The original source is linked at the end. That's where the original thought came from. This post may differ from that source though.

Ah, ok, but when I click on Theia, the site it redirects me to doesn't talk about Theia, but about a rock band from New Zealand.

Oh, seems it is a mistake, Thank you
