Researcher Answer to : Is the thinking of a brain faster than the speed of light?

The question for the question is How to Measure the Speed of Mind ? or some say Speed of thought?.  Actually The “speed of thought” is not measured physically with respect to WRT length divided by time, thus it cannot be compared to something that is measured with respect to Time and space. There is no physical existence of thoughts, so we cant say that it travels. Anything that travels itself means it must have some velocity in spacetime. and also something must strat a particle to start or travel from one point to another point. 

However, thought is a space occupancy i.e. in terms of bits &bytes when it comes to storage in general information form, but that too (memory, thoughts are) transferred by electrical signals in the brain. in the present situation information the Computers / or memory storage devices, the memory would be measured in something like bits per second or transactions per second, not meters per second. The transmission speed of nerves, however, can be measured in meters per second. But nerves are surprisingly slow. in practical approach Depending on the types of nerves, and body type, the speed of transmission varies between less than a meter per second and a couple of hundred meters per second. So even the fastest nerve impulse travels more than a million times slower than light. i.e By thoughts, I mean information in our brain, which obviously travels in the form of electrical signals( some neurotransmitters particle ions) and not faster than the maximum speed limit of any particle, which is less than the speed of light. So the information in our brain doesn't travel faster than light.

In another words it is Easy to understand from The NEWTON's LAW's

Newton’s first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. 

Newton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. The momentum of a body is equal to the product of its mass and its velocity. Momentum, like velocity, is a vector quantity, having both magnitude and direction. A force applied to a body can change the magnitude of the momentum, or its direction, or both. Newton’s second law is one of the most important in all of physics. For a body whose mass m is constant, it can be written in the form F = ma, where F (force) and a (acceleration) are both vector quantities. If a body has a net force acting on it, it is accelerated in accordance with the equation. Conversely, if a body is not accelerated, there is no net force acting on it.

Newton’s third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction. This law is important in analyzing problems of static equilibrium, where all forces are balanced, but it also applies to bodies in uniform or accelerated motion. The forces it describes are real ones, not mere bookkeeping devices. For example, a book resting on a table applies a downward force equal to its weight on the table. According to the third law, the table applies an equal and opposite force to the book. This force occurs because the weight of the book causes the table to deform slightly so that it pushes back on the book like a coiled spring.

But 

Here comes another way to Answer this, as we all know that the Though have nO Physical form. so we can not compare and measure it with other forms which are measure in a physical form, and physical form have only travelled in the direction it initiated in previously with some Force of action applied on it. 

so the what's the use of comparing the light which must need initiation, and in which our mind/Thought need no initiation. and the purpose of light depends upon the application for which the light is initiated. 

for example, if we spotlight the moon from Earth(Laser), the light may reflect and can be visible to the human naked eye. but what s use of it, 

in the same sense if we spotlight in a Dark Wear house for searching a Mouse, the light may travel faster than any, but it is our brain to think and process the information for the action that our Body Does to action for the Purpose. 

Hence in My View, Thoughts have their own purpose.
