We only see the light reflected off of an object.  Google the invisibility cloak that scientists have comeup with.  It works by refracting and redirecting light .

Yes, it leads to blindness.  I can only see out of one eye now due to excessive consumption during my youth.  If only Yahoo Answers had existed then!

Yeah I was told that teachers could "see all." But now I know that that could only  be true IF they were the eye of sauron. ;)

Yes, Since the Star Trek show and The movies like the fly,\nI believe it is very possible that a machine can make people\nDisappear and Reappear. Maybe others will know eventually.

any barrier to communication or vision.

It definitely seems like that....never thought about it until today but I can definitely see it NOW.\n\nIt's too bad that someone would be so incredibly blind AND dense as to enjoy such a thing.

Very.\nAs with ALL animal species.  Watch and see it.\nThe only problem is that we TRY to hide from it, and cause ALOT of emmotional problems when we cant reconcile them.

That is the very purpose of being invisible in the first place.  The only way you could possibly find out is if you message the person who appears offline and they respond immediately.

I can't say I've ever noticed/looked.\nBut thatnks for raising awareness...I'll get back to you on that one.

None at all. The human gives himself too much importance. Essentially, the role of mankind is as unimportant as the role of rocks, mosquitos and, actually, anything in the universe. However, mankind would not survive had it accepted the absolute pointlesness of its existance and so, our elevating of humanity's status above something what it really is seems only natural.

No. Anybody can see it.

The bigger question is why are most humans obssessed with them.

Because they are seen as human beings?

Currently, we conclusively know of no such thing.  The majority of the scientific community thinks it unprobable that there ever was such a thing.\n\nIt is not an entirley impossible concept.  We see stranger things in nature.

Invisible, yes, in many ways. Like walking into a room where all of your 'friends' are and have the entire group get up to greet the person that walked in behind you. More and more now I just turn-a-round and greet that person too. Its still a blow to the ego when people dont even say hello, but I think it more in how i interpret their response to me than how they actually think about me. Maybe Im getting better at not taking people so personally. Then again I have still been known to go off and sit somewhere by myself and watch everyone mingle and have a good time. But only cause I enjoy people watching sometimes.
