Hace 2 días · The Hubble length or Hubble distance is a unit of distance in cosmology, defined as — the speed of light multiplied by the Hubble time. It is equivalent to 4,420 million parsecs or 14.4 billion light years.
Hace 2 días · As an object's speed approaches the speed of light from an observer's point of view, its relativistic mass increases thereby making it more and more difficult to accelerate it from within the observer's frame of reference.
Hace 3 días · The speed of light is one in a system where length and time are measured in natural units and the relativistic mass and energy would be equal in value and dimension.
Hace 6 días · Given what is known about modern physics today, it is quite easy to take for granted that the speed of light, approximately \( 3 \cdot 10^8\: \text{m}/\text{s} \), is the unwavering speed limit of the universe.
Hace 2 días · That was quick, that was quick. Moving at the speed of light. That was quick, that was quick. Guess I didn't cross your mind (guess I didn't cross your mind) Shame I didn't cross your mind. Oh, you could have waited for my tears to dry (dry) And you could have spared a thought and looked behind. Moving at the speed of light.

Hace 5 días · Event horizon, boundary marking the limits of a black hole. At the event horizon, the escape velocity is equal to the speed of light. Since general relativity states that nothing can travel faster than the speed of light, nothing inside the event horizon can ever escape beyond it, including light.
