Today's interesting question is here!
What's in the center of a black hole?
The mass of a black hole is so great that all the matter in its vicinity cannot escape its gravitational constraints. We don't know what the Black Hole Center is competing for.
However, according to Einstein's theory of general relativity, there may be a gravitational singularity at the center of the black hole. There, matter is squeezed into an infinite density by an infinite gravitational pull, and time and space cease to exist.
What is the hardest object on Earth?
Diamond is the hardest natural substance known on Earth, and it has a Moorish hardness (a standard for mineral hardness) with a head of 10. Inside a diamond, the carbon atoms are firmly bound together by sharing electrons, arranged in a tetrahedral-like structure that is difficult to move, which is why diamonds are so hard.
However, scientists used computer simulations to find that the rare natural materials wurtzite-type boron nitride and hexagonal diamond are 18% and 58% harder, respectively, than diamond. However, due to their rarity, they have not yet been tested for hardness in a laboratory setting, and they are not yet the hardest objects on Earth.
Can you build a human portal?
A 70-gram human body is made up of about 7×107 atoms, so a teleporter must accurately place each atom in its proper place, and even if only one atom deviates from its original position, it can lead to irreversible consequences.
In addition, the machine works by duplicating a copy of a person in atomic units from the ground of the earth.
It's not so much a conveyor as a photocopier. It's more like the person was cloned once, rather than the body going on a trip. And what will become of the human being, no one knows.
Why is my voice different from my usual voice in the audio?
When we listen to others, the air vibrations caused by the sound are picked up by the eardrum in the ear, causing the ossicles to vibrate, causing the fluid in the cochlea to move, which in turn causes the hair cells to swing.
In this way, mechanical energy is converted into electrical energy, and sound is also converted into electrical signals that are transmitted to the brain. When we speak on our own, the sound is transmitted directly through the bones and tissues of the head to the cochlea in the form of bone conduction, while "caves" such as our sinuses amplify the lower frequency parts of the voice, making our own voice sound deeper.
The two modes of propagation result in voices that don't sound the same.
