What can you do to know that you seen a ghost or spirit?
I love tachyons. My favorite particles. I expect when we finally discover a faster than light drive, it will be tachyon powered.
No, I don't post as physicalist. As far as education IO have a masters degree and am considered an expert in many fields. I really get tired of this demented paranoia, believing every body but you is posting under hundreds of other names. I've given my real name many times on this board. It's not all that hard to find my address and phone number. I have nothing to hide. Can you say the same?
