2. Ethan Siegel: Why Can’t Our Telescopes Find Planet X?
[We have plenty of telescopes capable of seeing incredibly faint objects, but we need to know where to point them. We have plenty of telescopes capable of surveying huge areas of the sky, but they can only see the brighter objects; faint ones are out of reach. And for objects in our own Solar System, because they reflect sunlight rather than emit their own, self-generated light, they cannot be seen by any modern telescope if they’re located beyond a certain distance.]

3. What is 5G, how fast is it, and when is it coming?
[5G is the „evolution” of 4G LTE, which is what currently lets us stream videos, music, browse the web and social media, and use data-intensive apps on our mobile devices.
For mobile devices like smartphones, 5G service will be transmitted much like 4G LTE is today — with antennas dotted throughout a city (rooftops, utility poles, etc).]
