What’s the point of exploring the Universe?

#AskEthan

With so much going on in the world and so many problems to solve, why should we be investing in exploring the Universe?

We must always remember.

Ask Ethan: What's the point of exploring the Universe?
There are so many problems, all across planet Earth, that harm and threaten humanity. Why invest in researching the Universe?

NEWS: Researchers used the James Webb Space Telescope to refine the orbit of two Wolf-Rayet stars—named for the Egyptian god of chaos—to a lengthy 190 years and confirmed a third star carves their ongoing carbon dust ejections. 🔭 🧪 (1/6) 🧵
Four dust shells expand away from three central stars that appear as a single pinpoint of light. The innermost shell is smallest, like the size of a thumbprint, and brightest. It is yellow and forms a backward lowercase e. A line at 3 o’clock swoops to the bottom-left in an arc that ends at 8 o’clock. A second line at 9 o’clock dips down to start, but then goes straight up, angling around the top. The second shell, about the size of a fist, is orange and has looser arcs. One appears from 4 to 7 o’clock. A brighter orange triangle appears from 10 to 12 o’clock. Its outer edges overlap, forming a rough circle. The third shell extends almost to the edges and is semi-translucent red, with similar arcs and a darker red line that also forms a faint triangle at top left. The widest shell is faintest and at the edges. A semi-transparent blue appears across the scene. A larger foreground star with spikes is at bottom left, and more distant stars and galaxies are strewn across the black expanse of space.
