Organizing and summarizing search results for youLord Kelvin was wrong primarily due to the following reasons:- He underestimated the age of the Earth by using an incorrect model for its heat loss, failing to account for the effects of radioactivity.
- His calculations were influenced by his belief in a divinely guided process, which led him to assume the Earth was younger than it actually is.
- John Perry, one of his assistants, identified flaws in Kelvin's reasoning but was hesitant to confront him directly.
- Recent evaluations of his theories have cast doubt on their validity, indicating that his conjectures were not supported by empirical evidence.
These factors contributed to significant errors in Kelvin's scientific conclusions.
