It's a dark universe... By Edouard Engels & Romain Thellier
a great video ! If i've understood it weel, black matter is everywhere and impact on gravity. But how does it impact gravity ? Will scientists be able to see dark matter some day ?
Thanks a lot ! Dark matter has an effect on gravity, but we don't how yet. We can't see it directly, and, maybe we will never observe it. We gave examples of how it affects ordinary matter in the video. When dark matter is highly concentrated somewhere, the light that goes through is influenced by gravity. Because gravity can influence light, we can observe distortions, and then, we deduce that there is something that stretch the light in different forms. Also, we explained that the stars in the galaxies were spinning too fast. There must be something that keeps them coehrent, and this thing is "dark matter", because we don't know it's composition.
It's reality ! We know it's here ! As an example, we know that, on Earth, there are very deep oceans, but we don't know yet the full composition and life diversity it has ! It's the same thing for dark matter and our universe.
a great video !

Is it fiction or reality ? I don't understand how we can't understand what makes a dark matter if we know the impact of it.

DeleteThere is a dick in the potage
ReplyDeleteExcellent I love your video, the little blond person is so talented ! He is like a real physician. And he has that little smile OMG
ReplyDeleteHi Mr Good Deal,
DeleteDo you have any question on the video or concerning the theme?
Yes do you think there is a possibility of finding some black matter and taking it to Earth in order to study and maybe to find a way of using it ?
DeleteWe don't need to "bring back dark matter on earth", because dark matter is everywhere in the universe. Don't you think this is awesome ?
