Q & A

What are the most common types of questions asked in Startalk's Cosmic Queries?
-The most common types of questions are related to the end of things, such as the death of celestial bodies or the end of the universe.
What are some skills that would be useful in a post-apocalyptic world?
-Survival skills such as advanced scouting (Eagle Scout level), weapon proficiency (like a bow and arrow or a gun), hand-to-hand combat, and the ability to find and prepare food are essential.
Why is having a talent that others value important in a post-apocalyptic scenario?
-A valuable talent ensures that you have something to offer in a community, which could increase your chances of being included in a group that might survive and rebuild civilization.
What is the significance of interpersonal relationships in a post-apocalyptic setting as portrayed in The Walking Dead?
-Interpersonal relationships become crucial as they determine how people respond to each other and the challenges they face, often becoming more important than the actual threat posed by zombies.
What is the concept of 'spaghettification' in the context of black holes?
-Spaghettification refers to the process where an object is stretched out into a thin, noodle-like shape due to the extreme tidal forces exerted by a black hole.
How does the regeneration ability of a fictional character like Wolverine interact with the concept of spaghettification?
-Even if Wolverine could regenerate, the tidal forces of a black hole would separate his body parts to the point where regeneration would not be possible, as the gaps between the separated parts would prevent the regeneration process.
What is the expected future state of the universe according to current scientific understanding?
-The universe is expected to continue expanding indefinitely, with stars burning out and the overall temperature dropping. Eventually, the universe will become a cold, dark, and diffuse place.
How does Neil deGrasse Tyson envision his ideal death?
-Neil deGrasse Tyson has expressed a desire to die by being launched into a black hole, with the hope of contributing to scientific knowledge until the very end.
What is the concept of 'Hawking radiation' in relation to black holes?
-Hawking radiation is a theoretical process by which black holes can lose mass and eventually evaporate. It is named after physicist Stephen Hawking who first predicted this phenomenon.
How does the idea of black holes and their growth relate to the structure of galaxies?
-When galaxies collide, their central supermassive black holes can find each other and merge, forming a larger black hole. However, this does not lead to a scenario where all matter in the universe ends up in one black hole due to the accelerating expansion of the universe.
What is the likelihood of an individual's atoms spontaneously combining to form an alien life form billions of years in the future?
-While it is theoretically possible due to the identical nature of fundamental particles like electrons and atoms, the likelihood is highly speculative and would depend on numerous factors including the specific conditions and processes occurring over astronomical timescales.
What are the psychological considerations for long-duration space travel or colonization?
-The ability to endure isolation is a significant factor. Some individuals may be well-suited for extended solo missions due to their temperament and ability to function with minimal human contact.
