Hidden Secret in the Quantum Grove?

On Timber Hearth, there's a tablet depicting what looks like a portal inside a large tree:

This looks to me like a hidden secret in the Quantum Grove. The Tower of Quantum Knowledge did say that each quantum shard had a lesson to give (or something similar).

I've tried googling and I haven't seen anyone talk about this image. Has anyone tried to recreate the image in the grove to open a secret?

Also, the Quantum Grove has one tree that is noticeably larger than the others. I can't shake the feeling that it's the one shown in the tablet, but I personally couldn't get the trees to align or make anything else happen.

Seems like a mistery... what is the white thing inside the tree?

There's talk of it representing the hollow tree that is now our launch platform, I'd say it'd be weird for wood to hang around for a gazllion years but some of the crash sites still have wooden platforms..

I think the lesson there is just that something odd is happening. There are some references later as well.
