What is Relationship: Definition and 1000 Discussions

An intimate relationship is an interpersonal relationship that involves physical or emotional intimacy. Although an intimate relationship is commonly a sexual relationship, it may also be a non-sexual relationship.
Emotional intimacy involves feelings of liking or loving one or more people, and may result in physical intimacy. Physical intimacy is characterized by romantic love, sexual activity, or other passionate attachment. These relationships play a central role in the overall human experience. Humans have a general desire to belong and to love, which is usually satisfied within an intimate relationship. Such relationships allow a social network for people to form strong emotional attachments.

    I Relationship between stellar mass and core mass?

    Is there an astrophysical relationship between the how large a star's core gets and how large the star itself gets? Is it a simple linear percentage, or something more complex? For example, red dwarfs can fuse their entire hydrogen allocation, so the whole star is the core. But the Sun has a...

    What is the relationship between gravity and density?

    What is the relationship of gravity to density? In black holes the cause of gravity is that the star shrinks and becomes dense.
