What if there was a black hole in your pocket?

TL;DR

If a black hole the size of a coin appeared near you, it would lead to your immediate death due to its intense gravity and consumption of matter.

Transcript

What would happen to you if a black hole the size of a coin suddenly appeared near you? Short answer: you’d die. Long answer: it depends. Is it a black hole with the mass of a coin, or is it as wide as a coin? Suppose a US nickel with the mass of about 5 grams magically collapsed into a black hole. This black hole would have a radius of about 10 to... Read More

Key Insights

• 🖤 Black holes can exist in minuscule sizes, comparable to atoms, and can quickly decay into explosive energy.
• ⬛ Slightly larger black holes, with the diameter of a coin, would be more massive than the Earth and would have devastating gravitational effects on nearby objects.
• 🤕 The gravitational force experienced on a black hole would vary significantly between the head and feet, leading to the tearing apart of an individual.
• 🖤 Consuming the Earth, a black hole would cause the planet to orbit around it and result in disruptions and bombardment of rocks in the Solar system.
• 🥺 The Moon's orbit would be highly disturbed by the presence of a black hole, leading to significant ellipticity and further disturbances.
• 🖤 Tidal forces from the black hole would disrupt asteroids and potentially cause bombardment and impacts throughout the Solar system.
• 😚 The overall effects of a black hole in close proximity to Earth would be terrifying and lead to widespread destruction.

Questions & Answers

Q: What would happen if a black hole the size of a US nickel appeared?

The black hole would have a radius smaller than an atom and would quickly decay into an explosion larger than atomic bombs, resulting in your death.

Q: How would a black hole the size of a coin affect a person standing on it?

The gravitational forces would be so strong that it would rip your cells apart, causing your immediate death.

Q: What would happen if the black hole consumed the Earth?

As the Earth collapses into a scattered disk of hot rock, it would orbit the black hole, causing disruptions in the Solar system and bombardment of rocks.

Q: How would the black hole affect the Moon's orbit?

The black hole's presence would highly perturb the Moon's orbit, making it highly elliptical and causing further disturbances in the Solar system.

Summary & Key Takeaways

• A black hole the mass of a coin would be unbelievably small, even smaller than an atom, and would only exist for a fraction of a second before exploding with tremendous energy.

• If the black hole had the diameter of a common coin, it would be more massive than the Earth and would crush you with its intense gravity, tearing your cells apart.

• As the black hole consumed the Earth, it would cause the planet to bob and orbit around it, leading to significant disruptions in the Solar system and bombardment of rocks.
