@Jbinkley79 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.
@petebax1
It is funny how sensitive we are about colours and associating it with race. Once I was telling a story and when describing objects and food I unintentionally used their colour property as one of the first elements to characterise them and later on refer to them. Few minutes into the story I noticed the faces of some black fellows became very intense. Few days later I heard rumours that I am considered to be racist.
I realise most people avoid using colour to identify objects.
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?
@aubreyellenshomo Basically, while there may be some floating by and within the volume of the bag at any given moment, it's more likely that it's gravitationally bound to the earth or sun and happened to be in the bag because it's got some momentum and is passing through a bag which is also gravitationally bound to the earth and therefore sun. So, capturing air is quite superfluous to the goal.
Unless you have high-gravity plastic bags, in which case I want one.
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.
petebax1 - in case you're not joking (which I think you are), its called dark matter and dark energy because we know nothing about it. As humans, we see when there is light, and don't see in darkness, so its unknown and mysterious.
BTW - I think that thinking that saying "dark" is racist, is itself very racist, because it assumes that blackness means inferiority. No one said dark matter was inferior matter...
@petebax1
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).
Now just wait a cotton picken minute. You mean to tell me that the sun don't revolve around the earth and we ARE NOT the center of the universe???????
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 think this is racist why dark matter? Why not light matter or white matter, green matter,brown matter, etc, what you are talking about is weightless or matter without mass.
whats wrong with massless matter?
Apart from making Einstein look like an idiot. We can't do that?
I know we can call it ghostly matter or ghostly energy. That's much better.
Have you any spare bags?
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.
yea im just going with they T-pd your house because you gave them a empty plastic bag, kids dont really care for the whole dark matter thing a whole lot so yea...
I guess the kids gave you the toilet paper so that you'd have something to clean up all that dark matter with. ..lol...sorry I couldn't resist (the bad grammar was essential as well)
