It isn't clear at all what you mean. In any case, it isn't possible to travel at the speed of light - except for specific particles, such as photons (pieces of light), which can ONLY travel at the speed of light.
In an atom, the neutrons and protons are made up of up quarks and down quarks. Strange quarks, charms quarks, top quarks, and bottom quarks also exist, but do not play as much of a role in the structure of an atom.
Protons and neutrons contain quarks.
Actually quarks can exist freely.
Neutrons consist of small particles, called "Quarks". Protons also consist of quarks, but what quarks is made of, is still not discovered.
When the light is traveling through vacuum.
Heat waves traveling at the speed of light are called photon waves.
Electrons are able to travel close to speed of light.
Massless particles traveling at the speed of light include photons, the particles of light. They have no rest mass and always move at the speed of light in a vacuum according to the theory of special relativity.
Yes.
To an outside observer a person traveling at the speed of light would be frozen in time. To the person traveling at the speed of light, things would seem normal.
ANY light traveling through the same medium (stuff) has the same speed.
All photons traveling through a vacuum have the same speed, which is the speed of light in a vacuum, approximately 299,792 kilometers per second.
the same as you were if you weren't.
Traveling on a beam of light is not possible for objects with mass, as light moves at the fastest speed in the universe and cannot be caught up to. Traveling at the speed of light would also cause time dilation effects, where time would appear to stand still for the traveler.
The speed of light is determined by the electric and magnetic properties of the stuff it's traveling through. The "light" itself is just electrostatic and magnetic fields traveling together through the stuff. Change the electrical properties of the medium, and you change the speed of light through it.
The speed of light is always the same: 300,000 kilometers per second.
