- Since dinosaurs were discovered far below the earths surface covered in dirt, how does the earth gradually pile dirt on itself, forming layers covering up history over the past few centuries?

- How is it that the recently discovered “oldest spiral galaxy”, A1689B11, can be so well formed yet exist only 2.6 billion years after “Big Bang”?
- Do you become more contagious as a cold/flu progresses, or do you pose the same risk to others as soon as symptoms begin to show?
- How is meat "aged"; what is occurring at the molecular level and why doesn't the meat spoil? (Also, cheese)

| Does sleep deprivation cause permanent damage to the brain? Posted: 05 Nov 2017 06:38 AM PST I just got over a period of insomnia in which I was regularly going without sleep for several days at a time (this lasted about two weeks, in which I was maybe averaging four hours of sleep a night). Having recovered, I feel fine, but I have anxiety about what this might have done to my future academic performance. Should I be concerned? [link] [comments]  |

| Posted: 05 Nov 2017 02:27 AM PST Question in the title. I'm fascinated by what's actually occurring in the process of hanging and aging meat. I understand that you need to agree meat at least a little bit too drain off some blood but what else? Some people use large amounts of salt to make their cheaper bits of meat look and taste better whilst other times people tenderise it with a mallet. What's going on there too? And if anyone is interested enough, what the hell's up with cheese and maturing that for many years? [link] [comments]  |

| Why is the colour of an atomic explosion white, and not blue? Posted: 05 Nov 2017 05:21 AM PST As you can see from this image the colour of stars depend on the temperature of the star. My search shows that an atomic explosion is about 106 Kelvin. So shouldn't the colour of the explosion be blue? [link] [comments]  |

| Posted: 04 Nov 2017 04:13 PM PDT (Sorry, should have added in the title "For the broadcast of the UTC time signal for receipt by atomic clocks and wristwatches in the continental US.") I searched the subreddit and Google and found a lot of history and interesting details, but not the answer to this question. I know that the lower the frequency, the larger the antenna must be (like the enormous land-based ELF broadcasters that were used for deepsea underwater submarine radio), but surely1 there's a happy medium between 60kHz and 76Hz or whatever the ELF solution was that would more reliably reach the continental US and still be more than capable of transmitting 8bps. 1 Citation needed. That's why I'm asking the question. My education in terms of Electricity and Magnetism is only at an AP Physics level, anad that was 19 years ago, so as you can see I may be missing something fundamental here. [link] [comments]  |
| Posted: 04 Nov 2017 09:58 PM PDT We've heard a lot about mass shootings, stabbings, and other indiscriminate attacks in the news over the past ten or twenty years. What I'm wondering is whether this represents a culturally-motivated shift in the behavior of nutjobs from serial killings to parallel killings, or an actual increase in indiscriminate murder.

| Posted: 04 Nov 2017 01:06 PM PDT I know it may not be a very scientific way to discover things but I'm watching 'Split' and the psychiatrist in one scene is doing a presentation on Multiple Personality Disorder and she claims that someone can suffer from an allergy to Bee stings in one personality and not suffer the allergy in one of their other personalities, I don't know but Biologically speaking it doesn't sound right to me?
