Is the speed of light a convenient theoretical barrier, just as the sound barrier was thought to be impossible to break at one time..are we not just setting limits that do not exist

I personally think that it is. It is the ultimate fluid form of energy. To travel at the speed of light, you have to be light.

Sound is a form by which mechanical energy travels through various physical media from one place to another. The speed of sound depends upon the medium sound travels in. It is not constant. The speed of light, on the other hand, is independent of the medium. It is a universal constant.

All material things are in fact constructs of energy. All things move, change aand have certain characteristic physical attributes due to the way their energy has formulated.

Just imagine a wheel of a moving cart. Whatever speed the cart is moving at, the top of the wheel will always move with a double of the speed of the cart, and the bottom of the wheel will always be at rest - in contact with the ground. So, if something is moving fast the electron moving round the nuclei will have that external speed added to their basic motion, and vice versa.

According to the law of conservation of energy 'the energy of a system can neither be created not be destroyed'. The total energy of a moving object will therefore always stay the same. The energy used in motion through space plus the internal energy that mass is form of is the same both at rest and in motion through space. The faster an object moves the lesser energy it will have for physical formation until eventually the entire mass will turn into kinetic energy of an object moving at the speed of light – the light.

All things that move through space at a considerably faster speed undergo this transformation according to E=mc2. The motion of particles of matter is due to the energy they have. If an object moves very fast then that object will experience time dilation. The motion of all things inside a material object – electrons proton, will slow down to compensate for the physical motion of entire object.

It is not a barrier in the physical sense, but assuming an object could reach near light-speed velocities, it would warp the space around it causing the force necessary to increase velocity to increase. In that sense, yes, the speed of light is a barrier.

The only thing that is stopping us attaining or going over the speed of light in pilot-less craft is a propulsion unit.We haven't got anything like that yet,but the speed of light is not thought to be a barrier just the means of going that fast.

Okay,

Albert says that no INFORMATION can be transmitted faster than the speed of light.

Now there are physical effects such as quantum tunnelling and Photon Phase velocity where th speed of light appears to be exceeded but we can't get any information out of the process so that's okay.

If you want to travel as a person faster than light, it can't be done. However it might be possible to get from one point in space to another in less time that it would take light - as long as you don;t physically move through the space, by using worm holes etc.

So the answer is if you want to do anything meaning full in normal space time - then yes it is

Sound is a kind in which mechanical potential travels by numerous actual media from one place to a various. the fee of sound relies upon on the medium sound travels in. it extremely isn't any longer consistent. the fee of sunshine, on the different hand, is self sufficient of the medium. it extremely is a properly-known consistent. All cloth issues are in fact constructs of potential. All issues pass, replace aand have specific function actual attributes simply by way their potential has formulated. purely think of a wheel of a shifting cart. despite speed the cart is shifting at, the impressive of the wheel will continuously pass with a double of the fee of the cart, and the backside of the wheel will continuously be at relax - in touch with the floor. So, if something is shifting rapid the electron shifting around the nuclei could have that exterior speed further to their ordinary action, and vice versa. in accordance to the regulation of conservation of potential 'the potential of a equipment can neither be created no longer be destroyed'. the finished potential of a shifting merchandise will hence continuously stay a similar. The potential utilized in action by area plus the indoors potential that mass is rather is an identical the two at relax and in action by area. the quicker an merchandise strikes the lesser potential it may desire to have for actual formation until ultimately the entire mass will become kinetic potential of an merchandise shifting on the fee of sunshine – the easy. All issues that conflict by area at a drastically quicker speed undergo this modification in accordance to E=mc2. The action of debris of depend is with the help of the potential they have. If an merchandise strikes very rapid then that merchandise will adventure time dilation. The action of all issues interior a fabrics merchandise – electrons proton, will slow all the way down to make amends for the actual action of entire merchandise.

It is a barrier to anything with a rest mass greater than zero in the sense that the speed of light cannot be achieved let alone exceeded.

This is a natural result from Einstein's Special Theory of Relativity. Assuming that the observed speed of light is constant regardless of your frame of reference then, yes, you cannot travel faster than the speed of light.

We have no way of proving or disproving this argument. Generally we all know the common theories of energy and light travel, however as in many things before we cannot prove or disprove this at the moment. It is completely logical to assume that things other than pure energy can travel at the speed of light. As in all science the art is in proving the theory incorrect - not the opposite. I am sure in 20 or 30 years we will have a good basic answer to this question.

It is impossible. As you get closer to the speed of light, the amount of energy needed to increase your velocity approaches infinity. Hence, you would need all the mass in the universe to be converted to a energy source for you to accelerate to the speed of light.

The speed of light is broken every day by phase velocity of EM waves. Only the group velocity is limited by c.

happy speeding!
