Darkness:Yesterday you said"If it was still heat vision, nothing at all would have shown up except the lights."But if that were the case whould'nt you still see the lights in the original vision?.And did Keys not say they were using ultra violet radiation lights because they gave off no heat?.And the comment by Mr.Teal above?.Oviously people dont remember Arnold coverd in mud and not being see'n in
PREDATOR.So how can the pred see someone in -30* F temps?.And if the lights were hot enough to be see'n in my theory then it whould have been hot enough to melt its casing.I watch national geographic & theres two thermal cameras,one is for the jungle and it picks up heat signatures,if you were to use it in the arctic you whould'nt see anything,which is why you need the 2nd one,the one they used in AVP.And if it was radiation then whould'nt you have see'n the ultra violet light as well?.think of a lazer-pointer,you dont see the beam,but when you shine it through fog you can see it,or when you put your arm up to the sun you can see it,but you can also see the fog/sunlight as well.Its called back-ground radiation.The UV light passes through the room hitting the radiation creating a slight hollow in mid air.The pred whould have see'n that.
