Maybe. But that is also the part of the galaxy that would be the most hazardous to us because of the high amounts of radiation.

Still, if we HAD developed there, imagine what it would be like, interstellar travel might be halfway feasible. And that, would rocketh, it would rocketh HARD.
Climbing out of the Sea without Night we pass on to more diffused worlds. It would be frightening, a world of darkness.

I don't space faring civilizations would evolve on a world in the core. For one, stellar collisions are more likely and any earth-like world would have been ejected long before life could evolve. Also,, radiation.

Far all we know they can't imagine life in a world so lacking in energy. Besides, ejection doesn't have to be fatal, especially in a place with so much radiation.

Aren't a lot of the stars in the core older stars? Wouldn't they lack some of the elements needed for life (as we know it)?

Not impossible though. I'd like to see an intelligent gas cloud evolved near the core

I do not claim to know HOW, but I think it is reasonable that life COULD have evolved there. If it had, it would had to have developed the ability to withstand radiation. Any intelligent beings there would look at us and say "how dreary, cold, low radiation, and if our theory is correct, dark half the time! There is NO way anything life could exist there, simply not possible!". That said, any life near the galacitc core would certainly not be life as we know it.

And speaking of galactic cores, I saw Sagittarius set this morning. Well, it was posed an hour or so from dipping into the Pacific. Then the sun rose, and that with a half Moon.... Didn't see any aliens, I might add.

Who knows, they might be intelligent cockroaches...

This thread looks like I started it, but I did not, I was replying to a question that seems to have been deleted.

There was a mythbusters where they tested three different insects, and actually cockroaches did not do very well with radiation.

I forget now which bug survived better.

In any case, life as we know it could surely survive the radiation at the core. If Deinococcus radiodurans can do it, ET can too.

You're probably right that a radiation-resistant ecosystem would have to grow 'from the bottom up', starting with resistant microorganisms.
All later and more complex life forms would inherit this trait.

How much of that radiation would penetrate even 10m of water? Perhaps life near the Core simply stays aquatic.

The earth used to be more radioactive. Even if the core became uninhabitabe the inhabitants could always move outwards. They might be halfway along the Sagittarius spiral arm by now. If star travel is easier near or in the core then thats an incentive to do it.
