Can you travel in speed of light?

Answer 1

I believe that if we are to make a new element we can use it to travel at light speed, but whenever an element is found or made the atomic number, and mass increases we need to make an element lighter than the average 12.002-14.007,but what if we can make an element so abnormal and so structurally deformed we can make it so it is so light or heavy that it can gain enough speed to travel at light speed for example three elements come together and somehow cause them to react with each other and make that one deformed element. the travel of light speed will put us ahead by thousands of years
