You need to get further that the 4th gym leader to do that
yes but you need a special item
You don't. That's in Pokemon Diamond and Pearl. It's located in Victory Road and in the Galactic Hideout. Hope I helped. See ya!
In the team steam hideout after snowce city

No only in aqua's hideout.
I believe you can can find an UpGrade(used for evolving Porygon into Porygon2) in the Eterna City Hideout.
it is not really secret but there is the building in the north part of eterna city and a building in north veilstone city
Veilstone City :) x
After you beat Maylene the third gym leader go to the entrance of the Galactic Hideout you will see Dawn with two Galactic Grunts that stole her poke'dex you have to battle them and you kill Dawn's Clefairy. Then she uses Monferno.
there are two galactic buildings in the game. one is in veilstone city. and the other one is in eterna.
the galactic hideout but i think you need to beat the gym leader before you can get through.
Pokemon Fire red and Leaf green- After saving silph.co Pokemon Emerald- team aqua hideout Pokemon Diamond, Pokemon Pearl and Platinum- After defeating Cyrus at veilstone galactic base Pokemon Heart gold and Soul silver: Right before Ho-ho and Lugia
there is no underwater galactic hideout, the closest hideout you would get to underwater is the aqua/magma base in ruby and sapphire
yes but you need a special item
You find it in the Galactic Hideout in VeilStone city. You need to have met up with that strange dude "Looker" who opens the gated door, on the entrance to the Hideout on the left side of the city. The Key is in the first floor you come to, behind another gated door, you have to go the long way to get it though. (Through pretty much every floor, and several trainers).
one of the scientists near the end of the game, i think in the galactic hideout in veilstone
one of those scientist guys in cyrus's hideout
