Entonces en estas condiciones si no se da suficiente tiempo, el ojo no se podrá adaptar a la oscuridad y no se verán bien las estrellas del planetario al principio. Osea que lo ideal es una presala para bajar la intensidad de la luz. Además cuando se está dentro del domo de proyección y se sale, el ojo queda "encandilado" por la gran diferencia de claridad.

Según un experto que trabaja en una óptica, el ojo humano tarda en promedio unos 5 minutos en adaptarse a la oscuridad. Lo que pasa es que en un cine el cambio de la intensidad de luz es más gradual, en etapas desde que se entra a la presala y a veces pasan hasta 20 minutos hasta que empieza la pelicula. En el planetario está claro afuera y se entra directamente a la sala, con lo que se obliga a estar sentados esperando más tiempo hasta que se adecue el ojo a la oscuridad.

And also, the objectives of both arts are different. Even if judoka could win a mma fight with ground techniques, most of them would not participate on that kind of events. So until now there was not to much publicity about judo on mma. In the other hand, bjj made a big debut on mma fights and got a large reputation, and gained a lot of popularity. Even now I think that there is some kind of taboo for judoka to participate on mma fights, because we think of ourselves as sportsman.

I think that your appreciation is valid. And the reason I think is that in early judo, from 1882 to 1920 the martial art was more empathized on real fights and therefore a lot more on ground techniques. But as Judo developed into a sport it changed to a visual sport, and the judo you see today has more nagewaza on the matches. Nevertheless, depending on the teacher or practitioner, some people specialize more on newaza. I received classes from a Japanese master who was a "demon" on newaza.

if you study a little bit history you will see which one was first, and if the Judo "fake" newaza existed before or not. I recommend you the videos about Mifune or Kimura.
