How so?

I haven't watched it recently, but as much as I remember, this documentary takes the idea of heliocentric model and disproves NASA's point using their own arguments. It's brilliant for a new person exploring the topic - it proves that NASA lies, so they can give up on that illusion.

Since you're a veteran, I can present some other ones:

Although, you seem pretty convinced. So, probably you watched these, or you will find no new information in them.

As a fellow researcher, how easy was for you to figure it out?

I usually go with my personal experience and I remember that I mocked the topic for too long before actually exploring it... So, their mockingbird project really worked - people often mock before they actually give it a chance.

Actually, mocking is a defence mechanism to never give something a chance to be talked about, only mocked.

So, it's pretty hard, imo. I welcome anyone willing to explore the subject and debate. Mockers, tho... terrible for conversation. Brainwashed, as I was...

Probably we can think of a way to show them the truth. If you have any ideas, I am very willing to learn on this topic. We must do something about it.
