✨Black holes absorb dark matter, and over the billions of years since galaxies were first formed, this absorption of dark matter in black holes has very likely altered the population of galaxies from what we can observe today✨

✨At the core of radio galaxy Centaurus A is a super massive black hole, hundreds of millions of times the mass of the Sun. From above and below this violent gravity well, jets of matter shoot out at near light speed in two huge plumes. Each plume is over a million light years long, 10 Milky Way galaxies would fit along each plume‘s length✨

✨Active galaxy NGC 1275 lies at the heart of the Perseus Galaxy Cluster, it has huge filaments of gas that extend out from the core. They look like the tentacles of an immense galactic octopus and are 20,000 light years long, and just 200 light years wide. They are held in place by powerful magnetic fields from the massive central black hole✨

✨What would happen if a nuclear bomb was detonated in space?
💥When a nuclear bomb explodes on Earth, the huge release of radiation triggers the rapid expansion of air around it, causing the intense blast wave that wreaks so much destruction.
In the vacuum of space, the lack of air means the principal destructive effects come not from the blast, but instead from the particles and radiation pouring out of the bomb, which dump their energy as heat on striking the target✨

✨Quantum particles have one very unique property, namely they can be in different states at the same time. This is referred to as the "superposition" of two conditions. Based on this for instance the 'spin' of an electron can be pointing in two different directions at once✨

✨To a distant observer a clock near a black hole would appears to tick more slowly, this is gravitational time dilation. To the same observer, an object falling into a black hole would appear to slow down as it approached the event horizon, taking an infinite amount of time to reach it✨
