If a star is massive, it will remain in the main sequence a smaller star.

A massive star will remain in the main sequence for a shorter period of time in comparison to a smaller star

Explanation:

A larger and massive star usually remains in the main sequence up to a time when there is abundant hydrogen in its core. This hydrogen fuel helps in the process of fusion and change into helium. The luminosity and the age of a main-sequence star are directly proportional to each other and when the age of these stars increases, it gradually expands and eventually cools the outer layer of the star.

After a specific period of time, when the hydrogen fuel present in the core runs out then the process of fusion recedes, thereby stops the outward radiation of pressure. These stars typically live for a time of about 10-20 billion years and then dies off. For example, the Sun.

On the other hand, smaller and less massive stars can live up to about 80-100 billion years. For example, red dwarfs.

Thus, massive stars remain in the main sequence for a shorter period of time compared to a smaller star.

to be fair, you have to have a very high iq to understand rick and morty. the humour is extremely subtle, and without a solid grasp of theoretical physics most of the jokes will go over a typical viewer's head. there's also rick's nihilistic outlook, which is deftly woven into his characterisation- his personal philosophy draws heavily from narodnaya volya literature, for instance. the fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these jokes, to realise that they're not just funny- they say something deep about life. as a consequence people who dislike rick & morty truly are idiots- of course they wouldn't appreciate, for instance, the humour in rick's existential catchphrase "wubba lubba dub dub," which itself is a cryptic reference to turgenev's russian epic fathers and sons. i'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as dan harmon's genius wit unfolds itself on their television screens. what fools.. how i pity them.

and yes, by the way, i do have a rick & morty tattoo. and no, you cannot see it. it's for the ladies' eyes only- and even then they have to demonstrate that they're within 5 iq points of my own (preferably lower) beforehand. nothin personnel kid
