if anything does travel faster than light it is unknown to humans so far light is the fastest known possible earthly speed.

Theoretically their is a particle called a tachyon that travels faster than the speed of light. It exists only at one moment in spacetime and would be observed as two particles moving away from each other.Also, under the Lorentz Transformation, it would have an imaginary rest mass. According to Einstein, however, no.

Gravity travels at the same speed as light.
As for faster than light...well, no. Nothing of mass can travel as fast as light, that's for sure. It's impossible, the energy required to reach light speed would approach infinity.
As for massless particles...well, in theory you should be able to accelerate them artifically to faster than the speed of light, but no there is nothing we know of that actually does naturally travel faster than light does.

Only when light is passing through a material which causes it to slow down - then something can move faster than light IN THE MATERIAL - but still won't exceed light speed in a vacuum. The above example leads to Chrenkov radiation - that's how we detect neutrinos.

it's probable there are some extra stellar objects in space that travled faster than the speed of light in conception

no
it is not possible
as something aproaches the speed of light it gains so much mass that is slows down
