Science & Technology Q&A for Kids & Others:
​​Could we be inside of a black hole? Can biological life survive? Would something trapped in the liminal space between the event horizon and "singularity" eventually be able to escape? ​In a black hole, does time stop? Is this a case for string theory? What are the implications of a naked black hole (one without an event horizon)​ on the universe? ​It is very interesting that the more the black hole "eats," the larger the surface gets. So what exactly is the singularity? If matter and antimatter both have positive mass, then wouldn't Hawking radiation increase the mass of a black hole? How small can a black hole be? "Micro-black holes," maybe? Do you think it will ever be possible to reproduce a black hole situation in a lab for practical research/experimentation? What is spinning in a spinning black hole? Can black holes have a charge? Can the effect of the charge propagate out of the black hole if photons cannot escape? Why are they named black holes and not after the name of the people who found/discovered this phenomenon?​ ​ Could lasers be used to display an advertisement (or perhaps a clock) on the Moon? Can high-bandwidth internet connections be bounced off reflectors on the Moon? If the Moon is responsible for the tides, can the Earth be responsible for some micro-movement of moon dust?​ Buying an ad that burns up upon reentry sounds incredibly wasteful. ​​Would the tea dumped into Boston Harbor during the Boston Tea Party have affected the underwater ecosystem? How would biologists test for the effects of caffeine on fish? ​​Why are the elements on the Earth not more homogeneous? Why are there areas/mines abundant with certain metals? Is the heterogeneity of elements increasing or decreasing on Earth? Is this the same for other planets? Galaxies? View Less »
