Why Humans Can't Travel As Fast As Light Yet

Hey people!
I get it that travelling as fast or even faster than light has become an easy thing to do, in movies. Movies that feature this make it look as easy as running on a treadmill. But in reality, things get crankily egregious that travelling two-third  the speed of light can't even be attained by the fastest man made object.


Short answer:Albert Einstein proved in his theory of relativity that for one to travel as fast as light, you have to have an infinite mass,  and obviously no human can survive that without an extra-massive unique energy.

 Scientists describe light as a transverse electromagnetic radiation. Light is made up of photons; which have no mass. So this means, light has mass. Light claiming to be the fastest thing in the universe has a reason that's in no way near a bluff. Not even a bit.
The speed at which light travels can be rounded off to 300,000,000m/s I.e a distance of about 300,000,000metres per second.  Believe it or not, that's really  fast. Imagine distances we would cover in seconds. It's breathtakingly mind blowing.
The speed of light is nothing compared to the speed of sound. The speed of sound is approximated to about 343m/s,  I.e a distance of about 343 metres per second.
This proves that light as an electromagnetic radiation, travels faster than sound. A practical application is lightning and it's thunderous sound. The lightning(light) flashes  seconds before we hear the thunderous sound(sound) during a rainy day, literally.
 But what if we travelled at the speed of light?
How would it feel? Well, a person moving at the speed of light will experience time dilation. There would also experience time slowly(we'll get to that soon) and things ahead of them would appear to be in form of a tunnel. A practical illustration of the tunnel thingy is shown below

Time travel can also be experienced when a person moves at the speed of light. Einstein's theory of relativity supports this. It suggests that suitable geometries of space time or specific types of motion in space might allow time travel into the past and future if these geometries or motions were possible.
According to General Relativity, time travel is theoretically possible in certain General relativity space time geometries that permits travelling faster than the speed of light(300,000,000m/s), such as cosmic strings and traversable wormholes.

WHY THEN CANT YOU TRAVEL AT THE SPEED OF LIGHT?
Now I would bring in Einstein's theory of relativity again. Light has an Infinite mass consisting of photons that are without the slightest bit of mass.
The speed of light possesses a fundamental limit to the speed that an object can take, relative to the object nearby it. Infact, no object with any infinite mass can move at the speed of light. That is why stationary all the particles that moves at the speed of light, for instance, photons, have zero stationary mass. As a particle with mass approaches the speed of light, its energy increases before becoming infinite at the speed of light, which is the reason why it can never be accelerated to reach that speed. In few experiments carried out by scientists, it has been shown that nothing travels fast or faster  than the speed of light.
Let us assume we could travel as fast or even faster than  speed of light, what amount of energy do we need to attain such a challenging task?
David E. Fisher described in his words that the energy required to send a hundred colonists to another star at the speed of light would be enough to meet the energy needs of the entire united state over a human life time. And these estimates are regarding nearby stars(Alpha Centauri)
In conclusion, everything literarily shows that any object that is NOT massless, cannot travel at the speed of light without NOT surviving the high speed effects
