Can we perceive these things directly? I'd say we can't. We can only perceive them indirectly. We have no senses to directly perceive these things.

Zz.

The relationship between mass and energy is described by Einstein's famous equation, E=mc^2. This means that energy and mass are interchangeable, and one can be converted into the other.
Gravity is a force that pulls objects towards each other. The strength of this force depends on the mass of the objects and the distance between them. The larger the mass, the stronger the force of gravity.
Space-time is a concept that describes the four-dimensional continuum in which all events occur. It combines the three dimensions of space with the dimension of time, recognizing that they are interconnected and influence each other.
Math is the language of science, and it plays a crucial role in understanding these concepts. Mathematical equations and formulas are used to describe the relationships between mass, energy, gravity, space, and time, and help us make predictions and understand the world around us.
Yes, all of these concepts can be measured in different units. Mass is measured in kilograms, energy in joules, gravity in newtons, space in meters, and time in seconds. Scientists use a variety of tools and techniques to accurately measure these quantities.
