... • We know how much dark energy there is because we know how it affects the Universe's expansion. Other than that, it is a complete mystery. • It turns out that roughly 68%of the Universe is dark energy. Dark matter makes up about 27%. The rest everything on Earth, everything ever observed with all o ...

However, some light rays that are moving away at a given instant of time may find themselves trapped later if more matter or energy falls into the black hole, increasing its gravitational pull.
