Read some news and saw some stuff about like 7 seconds being a year on earth or like living up to 3158 years on another planet. How does that work. Like do i actually feel 3158 years cause to me is that i’ll still feel and live the same amount of time

It’s tough to explain because most people don’t realize that we actually use two different measures for time, even right here on Earth. The first, most daily-life time scale is the second and from it we derive minutes, and hours. It is defined by the frequency of a particular particle (I forget which one) and is considered a Fundamental Unit. The second is the year, which is a measure of how many seconds it takes the Earth to make a complete circumnavigation of the sun. There are at least two variables in that statement, though. The Sun – if you change which star you’re talking about, the length if a year changes, because the orbit would necessarily change. The Earth: because if you change which planet you’re using, the length of a year changes, again because the orbit nessarily changes. The number of seconds that actually pass doesn’t change at all and because how old you feel is dependent on the number of seconds you’ve experienced, it doesn’t matter which planet you’re on or how you measure years: if you’ve experienced 10,000,000 seconds, you’ll always feel as if you’ve experienced 10,000,000 seconds, even of that’s 5 years (didn’t do the math) on Earth and 40 years on Mercury or less than a year on Neptune.
Side question for everyone, though: is a year on Luna the same as a year on Earth? How about Io and Jupiter? Or do we measure a year based on the orbit around the parent body vice around the parent star?
