Which is most likely why many scientists reject the cold fusion theory?

Question

There is too much waste involved in the process.
Cold fusion experiments have been conducted at room temperature only.
The process does not produce enough energy to meet the needs of modern humans.
The original results have not been replicated consistently and reliably.

Answer 1

The most likely reason many scientists reject the cold fusion theory is that the original results have not been replicated consistently and reliably. Cold fusion claims have faced significant skepticism primarily because the initial experiments were not able to be reproduced by other scientists under controlled conditions, leading to questions about their validity.
