| Is the age of the universe influenced by time dilation? Posted: 21 Oct 2020 09:05 PM PDT In other words, we perceive the universe to be 13+ billion years old but could there be other regions in spacetime that would perceive the age of the universe to be much younger/older? Also could this influence how likely it is to find intelligent life if, for example, regions that experience time much faster than other regions might be more likely to have advanced intelligent life than regions that experience time much more slowly? Not saying that areas that experience time much more slowly than us cannot be intelligent, but here on earth we see the most evolution occur between generations. If we have had time to go through many generations then we could be more equipped than life that has not gone through as many evolution cycles. Edit: Even within our own galaxy, is it wrong to think that planetary systems closer to the center of the galaxy would say that the universe is younger than planetary system on the outer edge of the galaxy like ours? Edit 2: Thanks for the gold and it's crazy to see how many people took interest in this question. I guess it was in part inspired by the saying "It's 5 O'Clock somewhere". The idea being that somewhere out there the universe is probably always celebrating its "first birthday". Sure a lot of very specific, and hard to achieve, conditions need to be met, but it's still cool to think about. [link] [comments]  |

| How do vitamins help the immune system? Posted: 23 Oct 2020 02:19 AM PDT When I was younger, my mom would always tell me to take vitamin C do I don't get sick. I'm curious as to how exactly vitamins help the immune system. What part does it strengthen? Is it noticable? And how does it strengthen it? [link] [comments]  |

| Posted: 22 Oct 2020 11:58 PM PDT I've had this question for quite some time, and have been too embarrassed to ask. My understanding is that the vast majority of complications occur from ACE receptors being stimulated leading to inflammation, fibrosis etc in the lungs. Wouldn't an ace inhibitor theoretically increase odds of survival in a patient while the immune system fights the virus? [link] [comments]  |
| Why do nuclear power plants produce unique isotopes? Posted: 22 Oct 2020 07:00 PM PDT After the Fukushima disaster scientists were able to trace radiation detected in fish off the west coast of the US as originating from the Fukushima plant. I think there was a similar occurrence with Chernobyl If they are using the same fuel and the same process shouldn't the byproducts be the same? [link] [comments]  |
| Why did scientists believe an ice age was coming in the 70's? Posted: 22 Oct 2020 09:54 PM PDT My parents are heavily against climate change saying that we used to think an ice age was coming, now there's global warming and scientists "have no clue what's going on." The climate is something I take pretty seriously, but I don't know enough to refute this. Can anyone explain why we thought and ice age was coming and what changed our thinking? Any sources would sources would be appreciated, too. [link] [comments]  |
| How did NASA track the Apollo spacecraft? Posted: 22 Oct 2020 06:09 PM PDT In the movie Apollo 13, Mission Control in Houston makes frequent references to the eponymous spacecraft's orientation in space such as its approach angle to the atmosphere and so forth. It's clear that Houston was able to independently monitor these parameters, not needing to rely on the astronauts themselves for the information. How did Houston have this information? Some sort of radar system? How did they maintain a fix on the spacecraft throughout the Earth's rotational period, when the spacecraft would presumably periodically "set" on Houston?

| Posted: 22 Oct 2020 11:56 AM PDT Naturally, I realize the number does not differ too much from the number of protons, but is there some theoretical formula to determine the exact bounds? Or are the lists of all isotopes of an element based merely on successful observations and in principle, any number could be listed but the atom would instantly decay? [link] [comments]  |
| How do viruses survive freezing? Posted: 22 Oct 2020 12:04 PM PDT I was reading about the VIABLE Pithovirus, discovered 30m below the surface, frozen in ice, and I was wondering how did it survive the freezing process. From my understanding of biology and psychics, when water transforms from liquid state to solid state, it forms crystals, which penetrante cellular membranes(in our case it's not exactly a cell, but still a membrane). I guess that creating pores in the viral membrane(either from the intraviral water or the extraviral water) distrubts the virus ability to be infectious and thus replicate, resulting in the virus death. I'm sure that there are many people here that understand this better than I do and maybe can help me shed some light on the subject. Many thanks! (I apologize for my English) [link] [comments]  |
| Which viruses can "survive" drying out? Posted: 22 Oct 2020 10:34 AM PDT My understanding is that different sorts of viruses can vary wildly in how tough they are depending on things like DNA versus RNA and protein shells versus lipid shells. All viruses have to be able to handle immersion in liquid to remain infectious inside our bodies but how common is it for viruses to be able to have the liquid they are in dry up and still remain infectious afterwards?

| Do we see the concept of "ownership" in other species? Posted: 22 Oct 2020 08:34 AM PDT The idea that an item or place belongs to someone, that is have an individual or group of individuals control a particular item or place, seems to be a notion borne out of the scarcity of resources (such as land, water, food, etc.) so that one can better secure access to those resources. Do we see this sort of behavior in other species, for example, besides territoriality, the "ownership" of particular items that may be respected or contested by others of that species?

| Can you trace where specific gold was mined? Posted: 21 Oct 2020 11:57 PM PDT I knew a guy who worked for the Kennecott copper mine, and during his time there he snuck some gold out and took it home. He said he is unable to do anything with it or sell it because it has a specific DNA and can be traced back to the mine and he would be in deep crap. Is he meaning that it has specific minerals and compounds in the ore itself that when looked at, you can locate the geographical region it was mined based on those properties? [link] [comments]  |
| How does cancer from tobacco products work? Posted: 22 Oct 2020 06:58 AM PDT So for things like throat cancer, does it slowly build the cancer, or does one cigarette just happen to cause the cancer? If it builds up, where is the line drawn where it just becomes cancer? [link] [comments]  |

| How is a new test for a previously unknown virus evaluated? Posted: 22 Oct 2020 03:54 AM PDT A friend of mine brought it up to discussion, how is a new test for a previously unknown virus evaluated while there aren't any tests to compare it with? I suspected that maybe they compare it with antibodies blood tests but I couldn't find any easily accessible information online, probably because Google brings up a ton of Covid-19 news related results if I include the words "virus" and "test" in my search. Thanks in advance! [link] [comments]  |
| How does propulsion in outer space work? Posted: 22 Oct 2020 03:49 AM PDT The propulsion systems on space suits and craft blow out some kind of gas, but with no atmospheric particles to collide with, it boggles my mind as to how this propels people/craft [link] [comments]  |
| Do we know the false positive/negative rate of the quick pcr test? Posted: 22 Oct 2020 12:06 AM PDT Since it's being used everywhere around the world for confirming people aren't contagious. [link] [comments]  |
| Do bugs feel the same amount of pain we feel when we lose a limb? Posted: 21 Oct 2020 07:34 PM PDT |
| Posted: 21 Oct 2020 07:31 PM PDT Asking as a matter of pure morbid curiousity. I don't mean to suggest that I think mankind has released a trivial amount of emissions. Would Yosemite's eruption also lead to an extinction-level event? [link] [comments]  |
| The chemistry of baking cookies? Posted: 21 Oct 2020 09:44 PM PDT Hello, I'm curious as to what's going on with baking cookies. The baking sofa is to create bubbles but the salt is there to stop it. The flour gives structure to the cookie, but the butter is there to keep it non-structural (soft). Meanwhile the eggs are thrown in to glue everything together since the flour hasn't been worked enough to develop gluten. It's a very tasty work of counterproduction. [link] [comments]  |
