A new study gives the first evidence that exoplanets exist beyond the Milky Way.
While interesting purely out of curiosity, what possible use can we get out of that? Even if the observers are completely accurate, they're looking hundreds of thousands, or millions of years into the past. What they see hasn't been where they see it since before the dawn of humanity. And we couldn't reach it within the lifespan of our species.
You don't know how light works, do you?
Light from a planet on the other side of the Milky Way is only 100,000 years ago. Andromeda is only 2.5 million light years away.
By observing, we can learn tons of information. Plus, this also confirms what we thought: stars and galaxies spawn planets, moons, etc.
You must be fun at parties.
