    It appears to me that the dark matter, seeing as it doesn't interact with normal matter, that it would just leave the bag ;)

    I was wondering that too. [insert google search] Dark energy is 70%. And of course, this is the type of answer that just raises more questions.

    So what's the other 70%?

    If 5% is regular matter and 25% Dark matter than what is the other 70%?

    I am not sure if you are correct. Q: How much dark matter there is in a block of wood or a piece of metal? In your case it is volume of air. I thought the dark matter is mostly concentrated around the galaxy and there is less of it in areas where ordinary matter is concentrated - like solid objects or gasses? What do you say to that?

    Umm, That's not entirely accurate. While it is true that current estimates put normal matter at 5% and dark matter at 25% of the mass-energy of the universe, you also note this: "You can't interact with it in any way. ... We don't know what it's made of." Also true, so we have no reason whatever to believe it interacts electromagnetically. If it does not, it won't bounce off the electron shells of atoms that make up the bag. Thus, it won't be contained. Give them saran wrap instead.

    It's called dark matter cause it only interacts with normal matter through gravity (and maybe weak force), it's mass! So it has mass, and cannot be seen (which is electromagnetic force: light).

    Raceist? space is not divided into diffrent races. Its called dark matter cause it dosent emmit any light and therefor cannot be detected. There are allso diffrent forms like Cold dark matter, Hot dark matter, Warm dark matter, Light Dark Matter. You are way off with your assumptions that the colour would infer any spesific "race" in this matter.

    I dont know... May be it was just bright matter, which appears, when you try to catch dark matter with a plastic bag ;)

    Tony Darnell, I get the impression in this video that you are sceptical about the concept of dark matter. But you don't say you are sceptical, i just get that sense in your tone of voice in the video. I am very sceptical about the concept of both dark matter and dark energy. I think that in time science will catch up and prove that neither exist. If you read this, please to chat more about this in one of your infinate minutes. I would love to know your true thoughts about the topic. John.
