Description: SCP-XXXX-1 looks like an ancient wooden door that seems to be made of an indestructible material. SCP-XXXX-1 is a door which can change size depending on the doorway. The door seems to have sprung from ███████,██. The door when opened engages the person who opened it inside and instantly after the door closes and the door teleports to an alternative location to where a door would fit and periodically will replace a previous door.

Every door that has been replaced by SCP-XXXX-1 is discovered 3 ft away facing the floor. The door on the floor does not go anywhere when opened. When the door is approached, the door will instantly lights on fire and all remains will disappear.

The other side of the door is not visible by any sources and forces the viewer walk through the invisible side of the door. When touching the invisible side the person will instantly teleport inside the door and the door will appear opened.

Examining the visible side of the door you can see complete darkness. Light cannot penetrate the darkness and the unique way you can penetrate the darkness is with night vision goggles. Even now you can barely see 1 ft in front of you.

People who enter the door have currently haven't been unfound and are said to be in a box somewhere on the other side of the universe. (see addendum 1)

Addendum 1: This has been proven false as telescopes can not find this so called box but further research is to be conducted about this cosmic object.
