Before long, science and exploration teams are transmitting through the alien machine and arriving on the gateway rock. No one is quite sure where they are going, but it appears to be outside our physical universe. Controls on the gateway rock transmit the spacemen on to other rocks where they find alien machines, which seem oddly familiar yet function in completely different ways to Federation technology. No trace is ever found of the civilisation that built the Universe of the Floating Rocks, as it comes to be known.
We continue our brief voyage in the Thomas Öchsner's imagination...
Gateway Rock: After the transportation via the Secret Transmitter, the Spacemen enter the Universe of the Floating Rocks. The Gateway Rock coordinates the transportation between the different rocks of this strange alien environment.
