Minecraft Forums

I posted this on Galacticraft forums but no one answered so I'm hoping someone will here.

I have about 114 not including Galacticraft. When I try to launch minecraft forge it says starting game and then some other stuff and then it says Initializing and it doesn't do anything until I close it. Then the Minecraft Launcher pops up and gives me a bunch of stuff that I mostly don't understand. When I try to use it without the 3 Galacticraftmods it works fine. I didn't know if I should post it on the Galacticraft forums or somewhere else but I thought maybe someone could help me here. HERE IS THE CRASH(I don't know if it really counts as a crash)

So I'm pretty sure the slimevoidlib stuff doesn't matter. What I understand from this is that there was a problem with galacticraft mars and so minecraft couldn't load.

Is there a way to fix this?
What if I get an older version of galacticraft?
Is it because it is not compatible with other mods in my minecraft?

Thanks for the help So the only way to fix this is to delete some of the mods(the ones with more entities)? Or is there another way to fix this?
