Science & Technology Q&A for Kids (and others) [May 20, 2022]

Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series, also available on YouTube here: https://wolfr.am/youtube-sw-qa

Questions include: Do you think having many (eventually thousands of) IoT devices will necessitate some kind of additional routing logic on local networks to prevent primary devices (desktops) from being slowed? - ​​The implementation of IPv6 solved the problem of the number of possible internet addresses, at least. ​​​​- As higher frequencies are utilized in Wi-Fi to achieve higher bandwidth, Wi-Fi range and penetration are reduced. Is there some tech that would simultaneously increase both bandwidth AND range? - ​​​​​If gravitational waves travel through Penrose's eons, wouldn't these gravitational echoes make every particle wiggle at the quantum level, considering that there is a "noise" in spacetime? - ​​​How can we still see radiation from the early universe? Did it expand faster than light? ​​​​​Was it like a balloon expanding, where the light source was in the beginning expanded along with the universe? ​​- Is it theoretically possible to detect individual gravitons by launching space probes into black holes?
