Would you expect to find supernova remnants inside globular clusters? Why?
When a star undergoes a supernova explosion, it is very bright for a short time, but it also creates a “supernova remnant”, which is a bright gaseous region that usually appears ring shaped. These remnants dissipate over time, but several nearby supernova remnants are still very bright even though they were created over 1,000 years ago.

Yes, supernova remnants have been observed in globular clusters.
A globular cluster can produce a type 1a supernova because stars within them eventually become white dwarfs. If a white dwarf is near a red giant or in a close binary with one, it can absorb material from the red giant. If the white dwarf absorbs enough material to reach the Chandrasekhar Limit of 1.4 solar masses, gravity will overcome the pressure caused by electron degeneracy, causing the core to collapse and exploding as a type 1a supernova.

No, supernova remnants are not what you would expect to find inside globular clusters, which are old, dense star clusters where stellar interactions and supernova explosions are rare because they do not contain the massive, short-lived stars that usually go supernova.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
