i get very emotional when a breakthrough happens that i tear up
what a time to be alive
110 years ago we couldn't even fly for Darwin's sake isn't that amazing?????!!!!

Nevermind - 2018-07-21

I'm just bummed that we might be one of the last generations of humans with a finite life span. I believe it to be very likely that we'll soon find a way to stimulate any cell in the body to regenerate and/or repair itself to counter aging.

Christophe Paitrault - 2018-07-21

think about the consequences of such a thing.. it might not be that enjoyable.. first it wouldn't remove the death caused by accident/sickness etc, secondly it would make over population a HUGE problem in no time.. we're predicted to be 9b by 2050, if people "stop dying" from aging those numbers would sky rocket, not giving us time to figure out a way out.. here comes war, famine, crisis of all sorts..
and aside from all that, if you know your days aren't limited (except by other causes), wouldn't that change the way you live your life? why doing things today since you got all the time in the world ahead.. I believe our expiration date isn't the issue, it's what we manage to accomplish during our life time that matters..
I mean sure I wouldn't mind living long enough to witness all kind of breakthrough, will we ever discover other life form, travel to other stars, become better as a specie and so on, but the cons that comes along with that are not worth it for the good of all.. so let's just live the best we can with the time we have.. inspire future generation and you might live forever in the collective memory of mankind

Curtis Mowry - 2018-07-24

I love this attitude. I mean, how often can you sit back and just be in awe of creation. The vast complexity of it that we take for granted.

Jeramy G - 2019-10-02

@Curtis Mowry
Creation... Better to just say reality. Lol less assumptions involved.

Curtis Mowry - 2019-10-02

@Jeramy G fair enough

This is the third most exciting moment in Astronomy after the LIGO event and the Gaia data

Tony Bastian - 2018-07-20

I'm sure you mean recent astronomy? Galileo and Kepler made monumental discoveries, as well as many others

Morning Madera - 2018-07-20

not to mention the moment when they found out that the Universe is not only expanding, but accelerating in the expansion ...
or when they found out that the Universe is larger than the Milky Way
etc.

Robert Pruitt - 2019-05-05

I'd say the first picture after they repaired Hubble's vision, is the most important recent moment in astronomy.

That single image marks the beginning of Hubble making astronomy cool again to everyday people.

Something it did better than literally anything else in history except the moon missions.

The importance of the people of a country as a whole being excited by science cannot be underestimated, nor understated.

Amazing discovery !

Keith Durant - 2018-07-20

I love that the blue light is Cherenkov radiation..the neutrino was traveling through water faster than light travels through water...slower than light in space of course.

Keith Durant - 2018-07-21

Al Rats I'm no expert but this is the description I have for it. Cherenkov Radiation is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium. https://en.wikipedia.org/wiki/Cherenkov_radiation

Al Rats - 2018-07-21

Yes. Neutrinos are neutral particles. When a neutrino interacts with a water molecule, charged leptons are produced. These charged leptons in turn emit Cherenkov radiation. Neutrinos themselves do not emit Cherenkov radiation.

Keith Durant - 2018-07-21

Al Rats I see where I was mistaken...the neutrino creates a charged electron or muon. That particle is then the one, moving faster than light in the medium, that gives the radiation. Thank You

best you-tube comment interaction ever, lol. thanks to the both of you.

1:53 Looks like someone forgot about photons.

mlaygo - 2018-07-21

Photons are massless...

Wade Tisthammer - 2018-07-21

mlaygo

Ergo, photons have less mass than neutrinos.

mlaygo - 2018-07-21

Wade Tisthammer They obviously meant, "least massive" that actually still has mass. It's not that hard to get. You really thought you did something, smart-ass. 😒

Wade Tisthammer - 2018-07-21

mlaygo

Maybe that's what they meant, but that's not what they said. Take a look at what they said in 1:51 to 1:58. Don't you think that those less familiar with physics might get the impression from this video that neutrinos are by far and away the least massive particles known to physics? Might they then have felt misled upon learning that photons are less massive than neutrinos?

Karl Whalls - 2018-07-28

Not technically particles. Photons are not matter.

DUCKDUDE4100 - 2018-07-26

Wow, I'm still amazed that we're able to do things like this!

Whilst it’s really fascinating. I could highlight it seems to to have taken 100 Scientists and a multi-million dollar installation to publish something really inconclusive.

Christopher Elliott - 2018-09-14

Nice to see articles about Ice Cube. I helped build the array. Specifically, I was building and deploying Ice Top, the surface array. I assembled nearly all of the insulated tanks used out in Winchester, VA over 3 summers. I did a large part of the assembly of the 40 freeze controllers we used to monitor the freezing and degassing process in the tanks. And, I participated in 3 campaigns down at the South Pole to deploy the tanks, including the filling of the last tank. It was a big project with some great people and some fond memories. I'm really glad to see reports of results being reported to the general public. Thank you, also, to NSF for funding the project.

Daniel Houck - 2018-07-28

4:54 Could you please verify that this statement is correct? It seems highly unlikely that they were even doing the type of statistics necessary to make this claim. Did you perhaps mean "p < 0.0002", which is a very different number?

Ben Garrison - 2018-07-26

"They are far and away the least massive particles known to physics" - only electron neutrinos...and they're not less massive than photons. 😁

Their mass doesn't have anything to do with their undetectability, though. That line is misleading.
