think more on the sub atomic level.
the answers actually very simple.

although sound itself is not a physical entity, it relies completly on physical matter to be transmitted. because of this, the speed of sound can never be faster than the maximum speed any mass can attain. like dominoes. the wave of falling dominoes can never be faster than the maximum speed of one domino.
light, on the other hand, is pure energy, and doesn't rely on matter, so its speed isn't held to the same constraint.

I doubt it,
I think every body agreed that to reach that speed you must accelerate. And practically you must travel in space not on the street.
At this era all we know to accelerate in space people using the rocket power, by throwing backwards mass of gas.
Another fact is, rocket cannot have a speed higher than the mass thrown from its bottom (back), while we know up to now no one can launch gas or whatever don't talk about at the speed of light, even half of that never been reached.
But, when we can create and control magnetic field in our vehicle, then you will get constant force to constantly accelerate your vehicle to not only the speed of light but more.
There is also another way without magnetic field. Just direct your vehicle to the sun , I believe the sun's gravitational force will suck you progressively, and before you melt you experience the speed of light if you are still conscious.

Sound travels very slowly compared to light. I think sound travels at around 343 m/s if I'm not mistaken, compared to 3x10^8 m/s speed of light. Also, travelling at the speed of light requires infinite energy, and "infinity" isn't a real world number that we can use, therefore we'll never be able to reach the speed of light.

The speed of sound through air, at sea level and 70 degrees F is 770 mph.
The speed of light, to all observers, is 186,000 miles per second, or approximately 669,600,000 mph.
Those facts alone, without any help from relativistic theories, should suffice to answer your question.

To "cross" the sound barrier means you can go faster than sound, which humans have proved they can do... But, to go faster than light would entail a something in the vicinity of a black hole. Humanity hasn't proved they can do that though.. Or we would be time travelers right???

I'm not a physics major, but I remember my high school physics professor telling us that it's because mass increases with speed, so if something were to cross the speed of light, its mass would become infinity, which is impossible.

You know "the" answer? How many why's can your answer withstand? Repeatedly asking "Why?" to each answer will exhaust your knowledge. The more why's you can withstand, the deeper your knowledge.

because light is much faster than sound.
