Need help from great experts.

Please tell me the name of two films based on these descriptions.
1. A film from the nineties or the beginning of the two thousandth. The spacecraft on board of which a black hole was installed disappeared and appeared several years later. An expedition was sent to him.

2. The roofing felts fell to the Earth and appeared from nowhere, a huge rock, a stone that hung in the air a couple of meters above the ground. Scientists drilled a hole in the rock and it turned out to be hollow inside. Inside the cliff roofing felts, there was a ball lightning or something else.
