study. did it work? what did they find? well, again, i want to say again, it is early, these are small studies, i think in some ways this was proof of concept, but look at some of the findings here. gamma waves, the shorter, high energy waves that were stimulating the front part of the brain, they found that that actually did improve overall longer term sort of memory. they were giving people lists of words, people were able to remember the earliest words better when they stimulated the longer term memory stores. the fadeaways, saw that in purple, those are the shorter term memory improvements. and, again, significant memory improvements in this small group of people. they tested 20 people, and the gamma group, and 20 people in the other group and they did a sham group as well, basically put the skullcap on but did not deliver electricity and they found that that did not have an improvement. it was clearly this electrical current that was making a difference. not invasive
rippling through the gas cloud. these are picked up on planet earth, massaged by a computer, and amplified by 57 octaves, boosting it so that we can hear it with the ear. so you re not going to be able to go outside and go like this and hear a black hole from outer space. but what does it mean to scientists, to those of us who aren t just listening to the clip of it, what is the significant of it? it means that black holes are no longer science fiction, we can see these things in outer space, measure them. if you want to see a black hole tonight, go outside, look in the direction of sagittarius, that s the center of the galaxy. there is a black hole, weighs 2 million to 4 million times the mass of our sun and we on earth are moving around that black hole. and you can see it tonight, in the constellation of sagittarius. this is not just science fiction anymore. we can actually see these things, we can actually, quote,
