Question

How mass effects time, what is inertia and why time slows down for particles having mass when they approach to light speed?

Answer 1

How mass effects time?

When gravity affects an object, then his space time is being curved by the mass of one who provocates gravity. So, if time and space are being curved, the distance by an object has to travel is longer, so it's his time. In conclusion, mass curve space time and by curving space time, time appears and last longer.

What is inertia and why time slows down for particles having mass when they approach to light speed?

Inertia is a property of matter that causes it to resist changes in velocity. According to Newton's first law of motion, an object with a given velocity maintains that velocity unless acted on by an external force. The amount of inertia that an object possesses is proportional to its mass . However, inertia is not the same thing as mass or momentum. The mass of an object can be measured by observing the extent of its inertia. This is done by measuring the amount of force required to produce a certain acceleration .

The measurement of time slows down because the infinite cosmos is driven by a large-scale energy fields and moving an object through those fields at high speed produces side effects. One of those side effects is probably the regulation or deregulation of atomic or molecular process. so chemistry and biology would be slowed down or sped up to a certain degree depending on the circumstances.
