Whoever made that statement clearly did not think it through. Because it makes absolutely no sense, you will burn! Yes, stars are hot, except if it is a cold star. It is a wrong assumption that all stars are hot.
Stars are constantly giving out heat and burning through their hydrogen supply. Once their supply is depleted, it will begin helium fusion (into carbon) when the star swells into a red giant. It will end composed of carbon and oxygen, with the lighter hydrogen and helium layers blown off. This occurs for all stars between about 40% and 800% of the Sun’s mass.
The star will then turn into a white dwarf and will remain hot for an extremely long time. It will keep radiating heat and cool off for millions of years and eventually turn into a black dwarf. This is the life of a star in a nutshell.
The other outcome for stars that are much massive than our sun, they turn into neutron stars.
When the helium is exhausted, the balance of pressure and radiation tips and gravity wins, squeezing the star tighter than before. The core burns hotter and faster, while the outer layers of the star swell by hundreds of times, fusing heavier and heavier elements. Carbon burns to neon, neon to oxygen, oxygen to silicon, and silicon to iron. And then… …death.
Iron is nuclear ash. It has no energy to give and cannot be fused. The fusion suddenly stops, and the balance ends. Without the outward pressure from fusion, the core is crushed by the enormous weight of the star above it. (It implodes in itself). Particles, like electrons and protons, really don’t want to be near each other. But the pressure of the collapsing star is so great that electrons and protons fuse into neutrons, which then get squeezed together as tightly as in atomic nuclei. Long story short, this results in a supernova explosion.
So, do not reach for the stars; you will die.
So the saying “Reach for the stars” is fine metaphorically speaking, but not literally. Because you will literally YEET yourself out of existence.
That said, this is hard. This is going to be hard, really hard. But nobody said this was going to be easy, to begin with. So here we go.
