| 22618 | In modern physics the first and second laws of motion (unlike the third) fail at extremes [Ingthorsson] |
| Full Idea: While the first and second laws of motion are known to fail in the domain of very fast-moving and massive objects (i.e. where relativity deviates from classical mechanics) as well as in the quantum realm, the third law is still assumed to hold good. | |
| From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 4.04) | |
| A reaction: This implies a universal status for the third law (equal and opposite reactions), which the other two lack. Ingthorsson sees this as crucial for our understanding of causation. |
