Trustworthy science gives us trustworthy evidence. If we do not base our actions on trustworthy evidence, then we likely will waste resources and might cause great harm. One reason we view and discuss videos here is to learn how to recognize trustworthy science and trustworthy evidence. Also, viewing these videos is fun and much more uplifting than other news.
The hallmark of trustworthy science and trustworthy evidence is that uncertainity is reduced by replications with ever more reliable and ever more sensitive measurements and calculations. When replications do reduce uncertainities, then this bespeaks trustworthy. When replications are not possible we worry about trusting. When replications can be made, but are not, then this speaks against trust. When replications increase uncertainity, then this shouts against trust.
"More reliable" means lower error. A measurement of 1 foot plus or minus 1 inch is not very reliable. A measurement of 1 foot plus or minus 1/64th of an inch is more reliable. "More sensitive" means measuring smaller changes. A measurement of a 1 day plus or minus 1 hour change in the time of a full Moon is not very sensitive. A measurement of a 1 minute plus or minus 1 second change in the time of a full Moon is more sensitive.
The recent detection of gravity waves gives "reliable" and "sensitive" new meaning.
