what is the next fastest thing in the universe compared to light?

And how fast is it compared to light? 90 percent of that speed? 95 percent of that speed....?

    How fast a lie spreads. A lie goes halfway around the world before the truth gets its pants on.

    In physics things do not HAVE a speed. There is no one point in the universe to measure speeds from.

    It is impossible to rank things in order of speed except relative to some particular observer.

    Light has one unique property. Its speed is the same relative to any inertial observer.

    Whereas no other moving body has this property.

    The furthest reaches of the universe are moving at an extremely high speed RELATIVE TO US. But which one is moving.

      It’s amazing how often this gets forgotten....really is hard for people to get rid of the idea of absolute motion.

    Neutrinos were once thought to travel at light speed; that's how close they come to light speed. But they discovered that time passes for neutrinos; so as time stands still at light speed it's clear that neutrinos actually travel a tad less than light speed...99% plus.

    Neutrinos, being NEARLY massless, can travel at NEARLY the speed of light.
