Dark Matter: The Ultimate Halloween Treat

[Jbinkley79]

So what's the other 70%?

[sariahsue]

@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.

[uturniaphobic]

funny tail. tragic end, so if E = MC2 does darkE= darkMC2 ?

[wowsux97]

TROLLS!!!!! BEWARE THIS GUY HE WILL OUTSMART YOU.

[Sadoda777]

LOL both sides learned something. Kids learned science and you learned how to not to look greedy :D

[chives123456]

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

[fosheimdet]

Dark energy

[bulgariaisnomberone]

@chives123456

Dark energy, bro. May the F=ma be with you!

[gespilk]

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]

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.

[aubreyellenshomo]

@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.

[jetplane002]

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???????

[VictoriaFalls12]

lol that's hilarious, great punchline at the end. 5 stars

[petebax1]

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?

[Tgclove]

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.

[SeltsamerAttraktor]

@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).

[MyWorldView]

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...

[gespilk]

@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.

[MyWorldView]

Isn't the bag going through the dark matter? (or the other way round)

[john37309]

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.

[DaCr3at0r]

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...

[M0rdH0rst]

I dont know...

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

[kaleidoscope222]

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)

[TheReluctantKing]

Hahahaha

[daviddeath11]

whats the other 70% made of?

[k2ninja82]

@daviddeath11 Dark energy

[daviddeath11]

cheers m8

[stulogic]

LOL! Very good.

[thedeeliciousplum]

oh...doesn't this remind us of one of Newton's laws of motion? Action reaction.

"To every action there is an equal and opposite reaction" - Newton

I love the Aero bar suggestion by MtlRedAtheist.

[MtlRedAtheist]

tdarnell, your vids are awesome. Next time give them aero bars. You can tell them that the pocket bubbles contain dark matter :)

[kel2corkey]

Loving the videos man keep em coming.

[bobbocesu19]

i thought the other 70% was made up of 'Dark Energy' . Someone tell me if i'm wrong but i think thats right

[stuballs2]

Hi love the channel been subscribed for a while now and you have really been getting me thinking, so thank you. I have a question, maybe a dumb one but im no expert. If 5% is ordinary matter and 25% dark matter, what makes up the other 70%? Also someone was yapping about quantum theory and 18 dimentions of reality. I found some crackpot on youtube going on about 11 dimentions of reality but i just couldnt take him seriously. What are your views, if any, on this theory thanks and keep blogging

[djungbremen]

Excuse me, but do we know for sure that the dark matter is uniformly distributed in the universe? Maybe it only occures in the interstellar space or something.

[omegavalerius]

I guess the key part there too is: "We don't know." Gravitational lensing produced by galaxy clusters (the lensing effect being larger than what would be presumed when the visible matter is counted in along with black holes) would suggest that dark matter is found at least somewhere near ordinary matter so it might very well be that that bag has some of it in it.

[Macmula]

Hey man. Another interesting and entertaining video. Keep up the good work.

[Deliriousara]

funny and smart....what a catch!!

[Poordeadmouse]

What about the other 70%?

[KeiKusanagiDekar]

That's a good question!

[robomanus]

that must be something between ordinary and dark matter - perhaps unknown matter?

[Poordeadmouse]

I guess they are saying it's 'dark energy'. Does anyone know what the properties are of this 'dark energy'? I am really interested. Thanks.

[Capeau]

i dont know, i always flush my darkest of energy through the toilet

[nothinbuthax]

that's just fantastic. XD

[saharSA1]

@Poordeadmouse

dark energy makes the universe expand

[Zach1O8]

Love your videos. When I told my brother about how much dark matter is in space, he said, "Oh...so that's why space is so dark?"

[rjdaredevil]

lol....nice one

[crabbster21]

Today's NY Times (10-31-09) science section reports discovery of a "mysterious haze" of dark matter surrounding our galaxy's center. Many "new agers" now have special interests in what's going on in our galaxy's core, so maybe these findings will be an extra source of excitement for them.

[kennet1994]

''all good sicentist have to label things, cause thats what we do'':D

you kinda spoke to fast, i haved to go back a few times to hear what you said

(sry for the misspellings)

[joeddamage1]

scientist

[hoverpal]

Hello Tony !

I watched a few of your vids with my girlfriend, and we just found to be absolutely georgeous !!!

THANKS SO MUCH.

What you are showing is one of the best things media can bring to the people, so please please keep on what you are doing !

I could imagine even other breathtaking songs which would fit perfectly on your voyages through the Kosmos...

Take care !

[RythmEmotions]

haha

[trceb]

lmao your a bad bad bad person.

[RadhaBlossom]

The way you describe dark matter makes it sound like its impossible to prove it exists, and to say that there is dark matter in your baggie assumes that it is evenly dispersed throughout the universe. So then I must ask, how do you know?

[tdarnell]

We think dark matter exists by looking at the effects it has on ordinary matter we CAN see. The only thing we know about this stuff is that it has gravity. We can see it's affects on surround gas, dust and stars in galaxies.

For more info, google "nasa dark matter" and click on the first link. Good intro there.

[jpham227]

hellooooooo, tony.  :)

trick or treat!

[KeiKusanagiDekar]

Would that be like the gravitational lensing mentioned in one of your previous videos? Also, your Dark Matter treat made me laugh, though you had the toilet paper coming...

[valjazz]

I love it! Personally, I'd take dark matter over candy.

[anonymousstormchaser]

funny!

[crazytraininsane]

Lol, i'm so gona do that. =)

[RyuDarragh]

The only evidence that there is any such thing as "Dark Matter" is an observation that the Law of Gravity as we currently know it has difficulty explaining the apparent cohesiveness of galactic structures (how much gravity can keep objects in motion in a given orbit). If, by some wierd happenstance, they discover a non-linearity in gravitational pulls at extreme distances, then it goes away. At the moment, it's (Dark Matter) just a working hypothesis.

[Cadwaladr]

The earth is 32% iron, but that doesn't mean that if you put some rocks in the bag that there is necessarily any iron in there. Maybe you picked up rocks made of quartz and feldspar.

[Greywyn7]

32% iron is analogous to 95% dark matter?

[ipodchick21192]

your videos are so good. keep it up!

[Dryatu]

Keep on making these videos they are great

[shaurz]

Dark matter is still a hypothesis.

[yumagetbullet]

5% ordinary matter

25% dark matter

70% dark energy

[mummafier]

cool dint know but why is it "dark" matter/energy

[yumagetbullet]

ammm. not sure. but probably they named it because from our point of view it looks dark (,without light,)

maybe they just named it because they don't know what is it..

[nucliosis]

ahaha

[Jeffff23]

haha great vid!

[TWspooky]

I guess hydrogen was other 70%

[meskalin64]

Are we sure "dark matter" is randomly/evenly spread everywhere?

[blazpecnik]

what are the other 70% ?

[Simo102102]

We are in and ordinary matter environment (the planet Earth and its atmosphere) and no dark matter exists here. Dark matter is positioned in the Universe in clouds between the "nothingness of space". Please correct me if I have understood this all wrong...

[MrSikzak]

so what's the other 70%?

[yourpalcliffy]

perhaps nothin thats why they call it vacuum of space...

[superustipak]

dark energy is the other 70%

[superustipak]

dark energy

[skaterkid1477]

lol

[yomangr]

haha awesome vid:D

[MMOLegend]

Classic LOL,

[rollsthepaul]

We live in an illusion and are trying to figure out reality, from inside this illusion. Let's just put that one between fat chance and no chance.

[greycloud24]

bah dark matter is doubtfully evenly distributed. more likely we have more black holes than we are aware of. micro black holes come into temporary existance all the time when high energy particles collide. there are a LOT of these particles colliding very frequently.

[asalade]

If I can't interact with dark matter then why can the plastic bag. I'm not buying it.

[LiveAndLetDice]

hahaha, good plan!

[MariusGuitar2007]

Hehe. 25 percent dark matter in a ziplock bag is much cooler than some sugar candy that we already know what are :)

Nice Tony :)

[PivotDemon548]

Can I have one please? Lol.

[RJW37Films]

I laughed really hard - harder than I laugh watching YouTubers who strive to be comedians. I love it - keep up the great work Tony!

[ReinhardvonHolst]

our house would get egged if we tried that... but a good idea none the less.

[LVskywalker]

Keep up the good work Tony!

Dark matter for Halloween... I like the idea. It's like giving a glass of water to a fish.

[drowzy721]

Tony, you are DOWN with the kids!!!!!!

[RonWolf]

Orangejuice - Funny

I have a question, if common matter is 5% and dark matter is 25% what is the other 70% called?

[eskimokid]

The other 70% is a substance known as Snorgalamps, but don't try to find it because it has a very bad temper.

[winterstellar]

Totally great idea! There will be 25 percent dark matter in the bag, and that's super-exciting! But yes, it would be nice to put some candy in there with the dark matter, too. : )

[jeremylew416]

I would be pissed if I got an empty ziploc bag for halloween.

[Oranguice]

So the kids toilet papered your trees. On the positive side they didn't put any dark matter on the toilet paper.

[Oranguice]

This is a great idea. I'm thinking about giving dark matter as Christmas gifts.

[0TheSailor0]

Well ...you've said it , may be because the scintest could not discover what is it until now, thats why they call it dark matter. Even in our surroundings the space around us is not empty so what about the outer space !!!!!?

[BrandonFurtwangler]

haha. u could have put hydrogen in it & you'd have 70% of real matter. it would be just as lame for this kids though.

[darkskyva1234]

lol funny

[NYCFreed1]

haha, thanks for posting a video. you're one of my favorite uploaders on youtube by far, keep it up!

[tsjoencinema]

LMAO

That was really funny.

[hitchman84]

Yes! The Demon-Haunted World just right of Darnell's head.

Ooh, and Cosmos to our left.

[dragonfirefoxx]

I like your science things but um id have to egg your house lol

[BYMYSYD]

lol

[TheReasonWhyGuy]

You realize that the candy also has dark mater in it ;D

[TheReasonWhyGuy]

LOL

[babotSOmom]

LOL!!! I'll have to try that with my kids and see what they say :D Thanks for the laugh!

[BGenerous]

You only got TP'd? I thought for sure you would have been egged. :)

[N1ntenOwned]

Two videos in one day? It's like Christmas!

[William1990hill]

hey tony :) thanks for the upload

[NeedsEvidence]

Well, the Dark Matter would anyway penetrate the plastic of the bag, so you even don't to open the bag. :-)

[BGenerous]

Exactly. The bag always contains dark matter, just not always the same dark matter. :)
