A tiny black hole would either evaporate in a flash of energy (if extremely small, like a proton) or, if slightly larger, pass through objects like a bullet, leaving a tiny tunnel, potentially causing minor effects like localized heating or seismic signals, but larger ones could hollow out planets or cause significant damage through gravity and Hawking radiation. Its behavior depends entirely on its mass: the smaller the mass, the faster it evaporates; the larger the mass, the more destructive its gravitational pull becomes.
The small radius and high density of the black hole would allow it to pass straight through any object consisting of normal atoms, interacting with only few of its atoms while doing so.
“A sufficiently large primordial black hole, about the size of an asteroid or larger, would cause serious injury or death if it passed through you. It would behave like a gunshot. A smaller primordial black hole could pass through you, and you wouldn't even notice it.
If a black hole were to form on earth with enough mass to not immediately evaporate, it would eventually swallow the earth. Note that a coin-sized black hole has about the mass of the earth, so that would be immediately catastrophic.
According to theory, nothing hinders the existence of black holes on extremely small size scales. We could create a black hole with a Schwarzschild radius of 1mm if we were able to confine a mass of ~ 1024 kg (about ten times the mass of the Moon) within a volume of a pinhead; but this goes far beyond our capabilities.
When considering the notions of "embodied omnipresence" and the "incorporeal nature of God", we would be safe to say that, if God were present in a black hole in embodied form, the laws of physics would most certainly act on the being of God; God, with all other matter, time and space, would collapse into Godself.
About 95% of the universe is "invisible" because it's composed of dark matter (around 27%) and dark energy (around 68%), which don't emit, absorb, or reflect light, unlike the normal matter (stars, planets, us) that makes up the visible 5%. Dark matter's presence is inferred through its gravitational pull on visible galaxies, while dark energy is a mysterious force causing the universe's accelerated expansion.
In 1 sextillion years (10²¹ years), the universe will be a vastly different, dark place: the era of star formation will have ended, all stars will have burned out into white dwarfs, neutron stars, or black holes, planets will be cold and lifeless, and even protons might begin to decay, leading towards the "Big Freeze" or heat death, with only black holes slowly evaporating via Hawking radiation over unimaginable timescales. All familiar structures, including galaxies, will have long dissolved as the universe expands, leaving behind a cold, dark, and nearly empty expanse.
One minute near a black hole can equal years, decades, or even millennia on Earth due to extreme gravitational time dilation, where time slows drastically as gravity intensifies; the exact duration depends on the black hole's mass and your proximity to its event horizon, with the effect becoming almost infinite at the horizon itself, making an observer seem frozen to someone far away, though time still passes normally for the person falling in.
Your body stretches out, not uncomfortably at first, but over time, the stretching will become more severe. Astronomers call this spaghettification because the intense gravitational field pulls you into a long, thin piece of spaghetti. When you start feeling pain depends on the size of the black hole.
1 hour on Earth can equal 7 years in space (or vice versa) due to time dilation, a concept from Einstein's relativity where strong gravity or extreme speeds slow down time relative to an outside observer, famously depicted in the movie Interstellar on a planet near a black hole where an hour for the crew meant years passing on Earth. It's not about speed alone in orbit (ISS astronauts age slightly slower), but about proximity to immense mass, like a black hole, bending spacetime so drastically that time crawls for those nearby compared to time far away.
The big crunch, heat death, the big rip, vacuum decay, and the bounce are all different ways the universe could end.
There is consensus that supermassive black holes exist in the centres of most galaxies. The presence of a black hole can be inferred through its interaction with other matter and with electromagnetic radiation such as visible light.
This is why TON 618 is so interesting to astronomers: with an ultramassive black hole of 66 billion solar masses, it lies above King's estimate of the maximum limit (50 billion solar masses) for a non-spinning black hole.
According to Space.com, this new research gives credence to the theory of "Schwarzschild cosmology," which suggests that our galaxy is inside of a black hole, which, in turn, is located inside another, bigger parent universe.
The special theory of relativity implies that only particles with zero rest mass (i.e., photons) may travel at the speed of light, and that nothing may travel faster.
Initially described in Stephen Hawking's book “A Brief History of Time,” the first direct evidence of Spaghettication came in 2019 when astronomers at the European Southern Observatory's Very Large Telescope and New Technology Telescope witnessed the remnants of a Spaghettification event.
Humans Could Live For 1,000 Years by 2050—Ushering in the Dawn of 'Practical Immortality,' Futurists Say. Some experts warn that this radical change may remain out of reach for many, due to societal and economic challenges. Technology futurists foresee advances that will enable humans to live up to 1,000 years.
About 4 to 7 billion years from now, when hydrogen fusion in the Sun's core diminishes to the point where the Sun is no longer in hydrostatic equilibrium, its core will undergo a marked increase in density and temperature which will cause its outer layers to expand, eventually transforming the Sun into a red giant.
The Bible does not directly address the age of the Earth or the universe. The number of 6000 years came from Archbishop Ussher in the 17th century.
Space, or outer space, is a vast, near-perfect vacuum largely devoid of matter. This vacuum contains very few particles compared with Earth's atmosphere. However, it's not entirely empty. Space is dotted with scattered matter called the interstellar medium, which includes hydrogen and helium atoms.
These are the first words in the Bible: “In the beginning God created the heavens and the earth” (Genesis 1:1). Everything that exists has been created by God. This means the full expanse of the universe was created by God.
In space, where there are only near-empty voids between galaxies, stars, and planets, there are no air molecules to let conventional sound propagate. Nonetheless, space is not entirely silent.
