The behavior of matter has nothing to do with whether a person or consciousness is watching it
It's not the act of "watching" that changes behaviour... it's direct interaction. And everything (with mass) is interacting with everything else (with mass) because of gravity.

Matter behaves as it is insrtucted to based on the conditions in which it is exposed to. If you're standing outside with a thermometer, then you're taking heat from the atmopshere in order to measure the temperature of the atmosphere (assuming it's warmer outside than inside). It's changing because you're measuring it. The only way it wouldn't change is if the atmosphere was already exactly the same temperature as the thermometer. And even then, you'd be interacting with the atmosphere in other ways. You'd displaced air, and therefore changed the airflow of the atmopshere. Again, the most negligible effect one can imagine, but non-zero.

The idea you're "defying" physics is fundamentally flawed. One can't defy phsyics. If it appears you have done, then you've either discovered new laws of phsyics, or you took a bad measurement.
