In my first thread, I looked at the death traps analyzing the assumptions at the bottom of the concept. I made that thread in order to make clear how I think, and that science not always is comfortable. My only concern is what the truth may be, and that everybody - including myself - can always be mistaken. To be able to question everything - even oneself - without negative emotions getting in the way is the most valuable ability in science.
I'm looking forward to discussions that share different viewpoints rationally, as every viewpoint is part of the truth and therefore important.
In this thread I want to speak about a problem that has to be solved first when interacting with invisible beings. I'm not on the side that invisible beings don't exist, as I don't know the truth in that regard. But there are criteria that have to be met so that causality and plausibility remain.
Let me show you a short clip from the show "Stargate SG-1" to make the point:
So the logical problem can be described as follows:
When Harvey is standing next to Courtney on the beach, and there are no footsteps of Harvey in the sand - what is he standing on? In other words: How does Harvey interact causally with the visible world? If he is just out of the visible spectrum, that does not mean he is "not there".
For example: Radio waves are invisible, but they are there and interact with the visible world in a plausible way.
As the observation implies, Harvey does not move any visible matter in any way (even the air). So the question arises how he and the other invisible beings "stay" at the beach. Are they subject to gravity? If not, are they moving parallel to Earth with the same speed the Earth moves through space?
I don't want to come to conclusions at this point, as there are too many possibilites. Maybe I don't have the right picture of what really is happening. Maybe Harvey isn't there, but just a projection into Courtney's mind. I don't know.
TLDR: Courtney, please ask Harvey why he is not falling through the ground while not visibly interacting with the sand at the same time.
