Q&A 3: Running out of Hydrogen and More...

TL;DR

Answers to viewer questions on various topics such as logical functions, the myth of Nibaru, artificial gravity waves, the size of supermassive black holes, and the expansion of the universe.

Transcript

all right time for another question show uh we got a bunch of questions from the comments that I plucked out from now and older so let's get into them logical functions model 93 would a big pin cushion work for getting debris out like we build something designed to get debris lodged in it and then bring it back to Earth yeah so that's a great idea ...

Key Insights

• 😴 Cleaning up space debris is a significant challenge that may require innovative solutions such as using large pin cushions or running electrical currents through spacecraft.
• ❓ The myth of Nibaru or Planet X has been debunked for nearly 20 years, with no evidence to support its existence.
• 👾 Creating significant gravitational waves through moving masses in space is not feasible with our current knowledge.
• 💗 Supermassive black holes can grow indefinitely, consuming unlimited amounts of matter without any consequences.
• 🖤 Our solar system orbits the center of the Milky Way, where a supermassive black hole is located, although the primary focus is the center of mass of the entire galaxy.
• 🤩 The depletion of hydrogen in the universe would halt star formation and the creation of heavier elements, with no known method to replenish it.
• 🖤 The expansion of the universe and the warping of spacetime caused by black holes are separate phenomena that do not influence each other.

Questions & Answers

Q: Could a big pin cushion or an electrical current through a spacecraft be used to gather space debris?

While using a pin cushion or electrical current are interesting ideas for collecting space debris, they have their limitations. The pin cushion would need to be fairly large or have knowledge of where debris will go, while running an electrical current through a spacecraft could slowly attract nearby debris over time.

Q: Is Nibaru or Planet X a real threat?

Nibaru, Planet X, or any similar doomsday scenario is not real and has been thoroughly debunked. Lens flares and misinterpreted evidence are often used to support these claims. Rest assured, there is no impending planetary collision or any significant threat to our safety.

Q: Can gravitational waves be created by moving masses in space?

Moving masses in space do create gravitational waves, but they are extremely tiny and not impactful. Only when supermassive black holes collide do they create gravitational waves detectable on Earth.

Q: Is there a limit to the size of supermassive black holes?

There is no known limit to the size of a supermassive black hole. They can consume infinite amounts of matter without falling apart or exploding.

Q: Is our solar system orbiting the black hole at the center of the Milky Way?

Our solar system does orbit the center of the Milky Way, where a supermassive black hole is located. However, we are primarily orbiting the center of mass of the galaxy as a whole, which includes the black hole.

Q: What happens when the universe runs out of hydrogen?

Hydrogen is the building block of the universe, and without it, star formation and the creation of heavier elements would cease. There is currently no known method to create more hydrogen, so the universe would continue to exist but without the ability to form new stars and elements.

Q: Does the expansion of the universe slow down near black holes?

The expansion of the universe and the warping of spacetime caused by black holes are separate phenomena. The expansion of the universe is not affected by the presence or size of black holes.

Q: Can all the antimatter in the universe fall into black holes?

While antimatter can fall into black holes, it is unlikely that all the antimatter in the universe would disappear in this way. Astronomers would expect to see the interactions and explosions of antimatter early on if this were the case.

Summary & Key Takeaways

• Using a big pin cushion or running an electrical current through a spacecraft could potentially help gather and remove space debris.

• Nibaru is a myth that has been debunked for almost 20 years and there is no evidence to support its existence.

• Gravitational waves created by moving masses in space are microscopic and not significant enough to impact anything.

• There is no limit to the size of a supermassive black hole, and it can consume infinite amounts of matter without falling apart.

• Our solar system is not directly orbiting the black hole at the center of the Milky Way, but rather the center of mass of the galaxy.

• If the universe were to run out of hydrogen, it would signify the end of stars and the ability to create new elements.
