Question

mass distorts and curves space-time. this distortion of space-time results in gravity. this explains why light, which has no mass, can also be affected by gravitational forces. choose hypothesis scientific theory scientific law

Explanation:

A scientific theory is a well - substantiated explanation of some aspect of the natural world that is based on a body of facts. The description about mass distorting space - time and this leading to gravity, and also explaining the effect of gravity on light, is a well - supported explanation of a natural phenomenon (gravity and its effects), which fits the definition of a scientific theory. A hypothesis is a proposed explanation made on the basis of limited evidence as a starting point for further investigation. A scientific law is a statement based on repeated experimental observations that describes some aspect of the universe, often in a mathematical form, and it doesn't explain "why" like a theory does.

Answer:

scientific theory
