Not perceiving
A limit of our senses
Molecules, vibrations, radiation or physical variations can be present without becoming a conscious perception for us.
The starting question · Step 00
At the edges of the perceptible.
Does what escapes our senses also escape reality?
Our senses do not give us a complete picture of the world. They open a window shaped by our body, our history and the capacities specific to our species.
Not detecting
A limit of our means
A phenomenon may remain beyond the reach of our senses and of our current instruments. This invites us to look for a suitable method, not to jump to conclusions.
Not demonstrating
Knowledge that is still open
The absence of observation does not, on its own, allow us to assert that something exists. An intuition can open a question; it is not yet proof.
The limits of our senses
Other living beings encounter the same world differently.
Each species has detection capacities linked to its evolutionary history and living conditions. What remains inaccessible to us may be relevant to another organism. Recognising this diversity does not mean imagining communication everywhere: it simply reminds us that human perception is not the measure of all sensitivities.
Scientific instruments extend this window. They make imperceptible phenomena observable, but they always measure something defined, under certain conditions and with a degree of uncertainty.
The scientific frontier
Between the invisible and the unknown.
Not perceiving a phenomenon is not always enough to conclude that it does not exist. But not perceiving it does not allow us to assert its existence either.
The imperceptible is not necessarily non-existent. But the unknown is not yet proof.
Research begins when an intuition becomes a question precise enough to be tested against observations, measurements, alternative explanations and, where possible, the reproduction of results.
