The Cosmic Catastrophe of a Hypothetical Uranium Sphere: A Black Hole's Devastating Impact

Imagine a scenario where a sphere of uranium with a radius of 100 million light years suddenly appeared 300 million light years from Earth. This imaginary yet intriguing scenario would lead to a cosmic disaster of unimaginable proportions, culminating in the formation of a black hole and the ultimate doom of our planet and galaxy.

Formation of a Black Hole

Given that this hypothetical uranium sphere would be enormously massive, it would immediately collapse into a black hole without any possibility of an explosion. According to the calculations, the sphere's volume would be an astounding 4.2 x 10^24 cubic light years. Given that 1 cubic light year is approximately 8.5 x 10^47 cubic meters and uranium has a density of about 19100 kg per cubic meter, we can estimate the mass of the sphere to be:

The mass of the uranium sphere would be approximately 6.8187 x 10^76 kg, or 6818700000000000000000000000000000000000000000000000000000000000000000000000 kg. For perspective, this mass is so vast that it is equivalent to 68 quattuorvigintillion kilograms.

Size of the Black Hole

Considering the mass of this uranium sphere, it would also possess a Schwarzschild radius of 1 x 10^47 meters, or 1 x 10^31 light years. This means that anything within 1 x 10^31 light years would be immediately engulfed by the black hole's event horizon, marking the point of no return.

Impact on the Universe

As the black hole began to form, it would start sucking in the rest of the visible universe. Within about 300 million years, the black hole would eventually consume the Earth, the sun, and the entirety of the Milky Way galaxy. The sheer gravitational pull of the black hole would make it impossible for any phenomena, including an explosion, to escape.

Conclusion

In summary, the hypothetical appearance of a uranium sphere with a radius of 100 million light years 300 million light years from Earth would lead to the formation of a colossal black hole. The consequences of such an event would be catastrophic, leading to the annihilation of our planet and the destruction of much of the galaxy within a relatively short period of time.
