Because they don't want to be blue tiny's.
All stars eventually turn into Red Giants or Super Giants
Yes. The lowest mass stars are red dwarfs while many older stars turn into red giants and red supergiants.
Most medium mass stars such as our Sun DO become red giants. Smaller stars do not have enough mass to initiate helium fusion when the hydrogen supply begins to run low, and do not become red giants.
No, red giant stars are not the largest stars in the universe. There are stars known as supergiant and hypergiant stars that are even larger than red giants. These stars can be hundreds to thousands of times larger than our Sun.
Well light wise the highest category would be blue giants, red giants, and super red giants.
they live for a long time as regular sized stars then eventually they turn into red giants and explode then turning into a white dwarf
Red giants, red supergiants and red hypergiants.
No, they are mostly red dwarf stars.
Lots of them, Red Dwarfs are known to be the most abundant stars. Red Giants are less common but still red.
If they have red stars including giants in, they can't be all that featureless.
I think you are referring to red giants.
No, red giants are generally older than main sequence stars, as red giants have no hydrogen left for fuel, and burn helium instead. where as Main Sequence stars burn hydrogen for fuel.
