if its platinum i don't think you can because it leads to the reverse world where you just came from and ther is nothing there to see or catch because there aren't any Pokemon in the reverse world
its only a specific guess because im past that part
that's wrong. In platinum after you defeat the E4 and Cynthia you can go back into the Distortion World as Cynthia is not blocking the Path anymore. There, you can find the Griseous Orb.
u have to awake raquaza
beat the freakin elite 4 get the nat dex
you beat the pokemon league and if youre talking about the one on victory road you have to get the national pokedex

you need to fight them to get past
In which game?
u have to awake raquaza
Get the natinal dex
There are different entrances.
Give him a RageCandyBar. Sorry, I forgot where to find it, though...
there is another entrance on the left
you have to wake up the snorlax blocking the entrance to diglett's cave by putting on the lullaby on your pokegear,then get past diglett's cave to be found in pewter city.
beat the freakin elite 4 get the nat dex
You have to beat the elite four, and then he will move out of the way. You can also catch Mewtwo in there, in case you don't know.
You'll need the HM Whirlpool and teach it to one of your Pokemon and you can pass the Whirlpools blocking Whirlpool Cave.
If you are talking about the grunt in the cave on Mt. Coronet that is blocking cave you have to defeat cyrus,catch/defeat palkia/dialga/giratina, and then head for the cave where the grunt has left with the rest of his team.
