What would happen to time if we could travel faster than light?
Special relativity states that nothing can go faster than the speed of light. If something were to exceed this limit, it would move backward in time, according to the theory.

What is the speed of electric current?
The electricity is an electromagmentic wave and the speed of electromagnetic waves always equal to 3×10^8 m/s that is the speed of light. Hence the electricity flows at the speed of light that is at 3×10^8 m/s.

What is the difference between a magnetic and an electromagnetic field?
Electromagnetism deals with both electricity and magnetism and the interaction between them. Permanent magnetism or magnetism is the force that can cause two objects to attract or repel each other because of the motion of moving charges. Electromagnetism deals with both electric and magnetic fields.

I don't understand how light slows down in certain materials
When light propagates through a material, it travels slower than the vacuum speed, c. This is a change in the phase velocity of the light and is manifested in physical effects such as refraction. This reduction in speed is quantified by the ratio between c and the phase velocity.

F = m* a please explain
Newton's second law is often stated as F=ma, which means the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a). This means the more mass an object has, the more force you need to accelerate it. And the greater the force, the greater the object's acceleration.

The relationship between the quantum and the classical
Familiar formulations of classical and quantum mechanics are shown to follow from a general theory of mechanics based on pure states with an intrinsic probability structure.

Force exerted by pressure...
Pressure equals force divided by area (P=FA P = F A ). The equation shows that pressure is directly proportional to force, but inversely proportional to area. At a constant area, pressure increases as the magnitude of the force applied also increases.

Is Something Lighter on the Side of the Earth Facing the Sun?
The side facing away is cooler and darker, and experiences night. Because the Earth is constantly spinning, the line between day and night is always moving around the planet.

Why do we need a graviton?
Thanks a lot. This is a helpful information about the graviton.

Mass and Energy-Momentum
While normally we don't define a velocity for time, there is no reason we can't. Velocity is just distance over time. While it is quite common to express distances in units of time (i.e. light year), it is less common to express time in units of distance. However, if you do so, the definition for time velocity follows. To express time as a unit of distance, simply multiply by the speed of light. Velocities are always relative, so we need a second reference frame to use to measure the time velocity.

Light has no mass because gravity and light travel at the same speed, true or false?
Thank you for sharing this information.

What is the smallest object with mass?
Thank you for this information about this topic.

Why does gravity cause acceleration?
Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls.Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion.
