| Will the universe turn out to be very different for different speeds of light? Posted: 02 Jul 2022 07:55 AM PDT What if the speed of light is much slower or much faster than it is? Would the universe turn out to be different? My guess is that the speed is an arbitrary constant and its value may not matter but I am not sure. [link] [comments] |

| Will a small puncture at a vein cause more bleeding than a puncture elsewhere through the skin? Posted: 01 Jul 2022 04:18 PM PDT I was trimming bushes when I noticed a small thorn stuck itself into my knuckle. My finger looked normal and didn't hurt, so I removed the small thorn and continued trimming. 30 seconds or so later I raise the same hand up again and noticed I had blood all over the finger, and some had dripped onto my pants. By the time I noticed this it had already stopped bleeding. Did the thorn hit a vein or something, and removing it caused the area to bleed so much until it clotted? The area now has a bruise around a half inch in diameter. This thorn was incredibly small, and the puncture isn't even noticeable. It's really hard for me to believe such a small "injury" could cause so much blood. How could that much blood escape an invisible little puncture in only 30 seconds? I'm disappointed I didn't get to witness it. Edit: I'm glad this post got more attention than my popular comment about shirtless Li Shang from Mulan and the sexual awakening it inspired in me as a kid [link] [comments] |
| Posted: 02 Jul 2022 05:15 AM PDT Everywhere I look up the Tunguska event of 1908, it seems to suggest that a meteoroid of this size impacts Earth every few hundred years. Some go so far as to put it at around every three hundred years. But I couldn't find references to any other impact event of this scale from the last two millennia. What am I missing?

| What happens after a hormone binds with a receptor? Posted: 01 Jul 2022 04:18 PM PDT For example: Insulin binds to the insulin receptor, which causes a chain of events to happen to ultimately move GLUT4. After insulin binds to the receptor, what happens to insulin itself? Does it get released from the receptor? Absorbed? Does it change/get recycled? Break down? [link] [comments] |
| What’s the minimum density needed to form a black hole? Posted: 01 Jul 2022 06:25 AM PDT Is this a stupid question? Or does it depend? I thought that the answer is constant, but when I googled it I couldn't find the answer, only irrelevant things, can someone answer this question? Edit: aight guys this is solved thanks for the help.

| How do cells ensure crossover during meiosis doesn't result in fatal mistakes? Posted: 02 Jul 2022 12:20 PM PDT I am currently reading The Selfish Gene, and during one chapter he lightly touched on crossover during meiosis. I started thinking about crossover and I have a lot of questions that I can't really find the answer to. It seems like most places just touch on crossover as a step during meiosis, but don't really elaborate much. Anyway, here are my questions I hope someone can help me wrap my head around this:
Thanks for looking at my wall of text. I'm happy to restate questions if they don't make sense. Hope someone or many of you can help me with this. Thanks again! [link] [comments] |

| How does mixing magmas of different types cause large explosive volcanic eruptions? Posted: 01 Jul 2022 11:31 AM PDT I've read from several different sources that when a fresh injection of basaltic magma intrudes into a more silica-rich magma chamber under a volcano, some sort of reaction happens that ultimately leads to a large explosive eruption. I've specifically heard this implicated for the 19th century Krakatoa eruption, where people point to volcanic rock of varying color bands indicating partially mixed magmas that cooled preserving the different rock types. However, these sources don't mention a mechanism for this. Is there some sort of chemical reaction between the different magmas? Is it a physical reaction relating to different temperature/density/viscosity/gas content/something else? What leads two bodies of relatively stable magma to generate immense pressure and explode when mixed together? [link] [comments] |
| How do hot-spot volcanoes erupt after they are no longer connected to the hotspot? Posted: 02 Jul 2022 12:47 AM PDT For example - Haleakala on the island of Maui in Hawaii. It has had several eruptions within the past 10,000 years - and one as recent as 500 years ago. Isn't it far removed from the hotspot, or any connection to it? How could it still erupt?

| How are cancer rates going up when we've made regulations on regulations to control carcinogen use? Posted: 01 Jul 2022 05:04 AM PDT as the title says, it just seems like cancer rates are going up, but we've made tons of regulations, warnings and other things to show, limit or stop use of carcinogens. to me this means cancer rates should trend down. but they're not?? what would cause this in modern society??? are genes less healthy?? is our food worse?? are products really not that clean??

| How can the liver break down so many different chemicals? Posted: 01 Jul 2022 06:23 AM PDT The liver is where a lot of chemical compounds are broken down into useful or waste compounds. But how does the liver correctly handle so many different compounds? There are literally thousands and thousands of different compounds we can ingest, how do the liver cells know how to deal with each one correctly? [link] [comments] |

| Is there any scientific proof that air fryers are bad for you? Posted: 02 Jul 2022 01:56 PM PDT Other than the fact that adding oil to food is bad for you, is there anything about that way it changes the composition of food that is unhealthy or has long term adverse effects? [link] [comments] |
| Posted: 30 Jun 2022 11:11 PM PDT Most of my search results are giving me information on blood plasma, and I'm not finding a clear yes or no about the kind of plasma I actually want to know about. Is the definition of fluid absolutely applicable to plasma the same way it is for liquids and gases, or is it just used as a theoretical condition to lay down a framework for studying its behavior? Or, is it a "yes, but more complicated" situation kind of like how light is both a particle and a wave? [link] [comments] |
