I remember an episode, I think it was from The Twilight Zone or The Outer Limits.

A scientist finds a rock.

There is a world simulation happening on that rock, wherein grows a small simulation of our own evolution (by chance?)

The rock is then put in a room, inside a glass.

The scientist monitoring the rock world's evolution follows it with great interest as a comparative history method of our own evolution, and in hopes of predicting our own future, as they are evolving very quickly in a way very similar to the Earth´s history.

By the time it reaches the equivalent of our time and they master atomic energy, there appears a shadow around the rock.

The shadow turns out to be a ghost that does not let the observer follow the experiment or even get near the rock anymore.

Any idea of what episode is this?

    While not the answer, for a moment this reminded me of The Science of Discworld, where the wizards accidentally create Earth in a glass sphere.

I actually did even not remember that was also a similar series to The Twilight Zone called The Outer Limits before starting searching for the answer. It would not be the first time searching, but this time I just browsed the description of all episodes of the series of The Twilight Zone, and there found a reference to The Outer Limits.

Actually, I was thinking of Episode 8 from Season 2 of The Outer Limits, "Wolf 359", from 1964.

From imdb:

A scientist creates a tiny model of another solar system's planet, seeding it with life, to study planetary development. The miniaturization allows the simulation's evolution to advance much faster. A ghostly bat-like creature hovers on the in-closed model watching the humans, while emitting waves of fear terrifying them.

Confirming the plot from wikipedia:

As the evolution of the miniature world progresses, Meredith observes a reproduction of the darkest moments of Earth's history at its surface (including the development of nuclear weapons). Lowering his guard one night, the scientist is suddenly attacked by the creature; he is however saved by his wife, who returned from home at the same moment, and who breaks the miniature planet's containment cell, causing its atmosphere to escape, and subsequently causing the creature to be destroyed along with the planet.

  • @FuzzyBoots Thanks, will do it. Thanks for the edits. Jan 14, 2018 at 16:08

I believe you are conflating this episode "The Little People" https://en.wikipedia.org/wiki/Talk:The_Little_People_(The_Twilight_Zone) with Theodore Sturgeon's "Microcosmic God". https://en.wikipedia.org/wiki/Microcosmic_God You wouldn't be the first.

    I think it was none of both. The scientist was just an observer, and did not interact with the small world. Jan 14, 2018 at 14:23

    I withdraw my answer. I have, of course, seen the Outer Limits but not as frequently as the TZ episodes. Maybe caught the one in question just once. Jan 14, 2018 at 18:42
  • Nonetheless, your links are interesting. Thanks. Jan 14, 2018 at 18:47

    George R.R. Martin's story "Sandkings" shares some thematic similarities as well. Ironically, it was made into a two parter for the "New Outer Limits". Jan 14, 2018 at 22:47
