| Could solar power be used to cool the Earth? Posted: 30 Jun 2020 05:56 AM PDT Probably a dumb question from a tired brain, but is there a certain (astronomical) number of solar power panels that could convert the Sun's heat energy to electrical energy enough to reduce the planet's rising temperature? EDIT: Thanks for the responses! For clarification I know the Second Law makes it impossible to use converted electrical energy for cooling without increasing total entropic heat in the atmosphere, just wondering about the hypothetical effects behind storing that electrical energy and not using it.

| Where do files encrypted with password, like .rar files, store the password? Posted: 30 Jun 2020 01:00 AM PDT Sometimes I happen to download a .rar file protected by password, and when I view its content with software like WinRar there does not seem to be any extra file inside. How does the operating system know that the file is encrypted and what the password is? [link] [comments]  |
| Posted: 29 Jun 2020 05:11 PM PDT Well, how does it work? Take the current disease. There are asymptomatic carriers that never knew they had a disease. And then there are some that are going on ventilators. What makes one resin need a ventilator, and another person have no symptoms of any kind? And it's not just this disease. The flu gave me pneumonia this year, but my wife barely had a runny nose. [link] [comments]  |

| What do viruses do if the immune system doesn't respond? Posted: 29 Jun 2020 02:16 PM PDT For example, the flu. Most of the symptoms (fever, cough, vomiting, etc) are caused by our immune response. Are any caused by something that the virus itself does? What would these viruses do if our immune systems just ignored them? [link] [comments]  |

| What happens to a lizard's tail once a lizard has shed it? Posted: 29 Jun 2020 12:10 AM PDT Everyone knows that a lizard sheds it's tail when in extreme danger. But my question is, what happens to the tail? I know it still moves after removal, and that it will keeps moving for up to 30min. But does the tail decompose, or does it remain as if it was still attatched? [link] [comments]  |
