burst_ artwork 44 / Event Horizon: „The event horizon is the threshold around the black hole where the escape velocity surpasses the speed of light. According to Einstein's theory of special relativity, nothing can travel faster through space than the speed of light. This means a black hole's event horizon is essentially the point from which nothing can return. The name refers to the impossibility of witnessing any event taking place inside that border, the horizon beyond which one cannot see." - Quote: Charles Q. Choi - Pandemic 2020. PNG, 2794 × 3677
