I got a few red flags. I've learned to be wiry of academics. I looked up Tau Ceti in my charts and online and what I found was amazing.
What did you find?
It's very close. The star is very similar to our sun. The system may have at least 5 planets. It's of interest to SETI. There is something said about a dust or debris cloud that makes me wonder if it could be something else.
