I read in a book that mass is invariant. Does this mean that an object's mass does not increase as it approaches the speed of light?

No, according to Einstein's theory of relativity, an object's mass does not increase as it approaches the speed of light. Instead, its mass appears to increase from the perspective of an observer who is at rest relative to the object.
This is due to the fact that as an object's speed increases, its energy also increases. This increase in energy results in an increase in the object's apparent mass, but not its actual mass.
Yes, according to Einstein's theory of relativity, an object's mass would approach infinity as it approaches the speed of light. However, this is not physically possible as it would require an infinite amount of energy to accelerate an object to the speed of light.
The concept of mass-energy equivalence, as described by Einstein's famous equation E=mc^2, shows that an object's mass is equivalent to its energy content. As an object's speed increases, its energy also increases, resulting in an apparent increase in mass.
This has significant implications for our understanding of the universe and the laws of physics. It allows for the possibility of objects traveling at extremely high speeds without violating the laws of conservation of mass and energy. Additionally, it supports the idea of time dilation and explains why objects with high speeds experience time differently than objects at rest.
