| What is the smallest known object that still occupies space? Posted: 23 Dec 2019 07:00 PM PST So my understanding is that, according to the standard model, the fundamental particles are all point particles that occupy no space (or atleast, it is meaningless to talk about them having a size). But if I wanted to identify a "physical object" (I know that gets a bit fuzzy at these scales) that occupies some physical space, it must be some form of hadron, no? From looking online, it appears protons have a diameter of roughly 1e-15m, but is there anything smaller than that? I thought at first mesons might be, as they are composed of only two fundamental particles, but Wikipedia says that they are actually larger than protons. That leads me to believe that maybe more quarks lead to smaller objects, but that now gets in a territory that I know absolutely nothing about. So, is there a widely accepted "smallest" thing? Something that still has an accepted or measured (or even predicted size) that isn't a concept like the Planck length. [link] [comments]  |
| Posted: 23 Dec 2019 04:40 AM PST I know this question sounds silly but I just got a massage today and I was wondering why they are so beneficial to our body. Do they increase blood flow or reduce lactic acid buildup? Does the action produce endorphins and dopamine in our brain? Why do our muscles get sore anyway? [link] [comments]  |

| What’s the temperature inside a cavitation bubble? Posted: 22 Dec 2019 08:47 PM PST What is the temperature inside a water cavitation bubble? My employer gave me a pump operator class where I remember it saying it was hotter than the surface of the sun. I'm now in a heated debate with a coworker who insists otherwise. Neither of us can find a solid answer on the web. Please help. [link] [comments]  |

| What are signs of damage to the medulla? Posted: 22 Dec 2019 03:53 PM PST And can you have damage to the medulla without knowing it? [link] [comments]  |

| Why are so many dinosaur fossils from laramidia and not appalachia? Posted: 22 Dec 2019 05:58 PM PST And why are so many of laramidia fossils from the eastern coast of the continent? [link] [comments]  |
| How far up will helium travel? Posted: 22 Dec 2019 04:07 PM PST Will helium continue up and disappear into space or will it stay somewhere in the atmosphere? If it stays in the atmosphere, how far up? [link] [comments]  |

| Posted: 22 Dec 2019 01:35 PM PST That is, from a perspective of longevity and the "best course of action" for the body's immune system, when ailing from a non-life threatening infection - say, the common cold or a viral infection that manifests as a fever, which the body is able to eventually "defeat" on its own - is the human body better off tackling it using its own immune response or is it better off receiving external aid (like antibiotics)? If the body is left to tackling the infection using its own immune response, and the temporary bodily discomfort notwithstanding, is an otherwise healthy immune system able to fully recover from the damage caused by such an infection? Further, if it is able to recover, is such recovery to status quo, or does the immune system recover to be "stronger"? P.S. Please excuse the verbosity. [link] [comments]  |
