There are countless fonts that are largely recognizable as English letters and arabic numbers, but does someone write a standard for how the letters are to look officially that other letterings would be based on? Line thicknesses to space between them and direction, etc? I was looking at various...
Does anyone know the typical surface of totality during an eclipse? I want to figure how much that compares to earth's total surface area. According to the news a total solar eclipse happens every 18 months or so, but usually over the ocean. I want to figure the odds.
I'm near Buffalo and our last total solar eclipse was in 1925 and it looks like the one tomorrow will also be cloudy. What could increase the frequency if we could play god? Decrease the moon's size and orbit, stabilize its wobble in its orbit, etc? Without affecting the gravity effects on earth...
I only ask because those afraid of cell phone radiation giving them a brain tumor would get any dangerous radiation from the battery more than the screen. And that's very low power compared to a vacuum. I am not in charge of what vacuums are purchased at the cleaning company I work for, but...
I'm afraid that wouldn't work on carpets. Lol. As for a powerpack I am still concerned with safety and health with such a power supply if any. Would anyone here have any reservations about strapping that much power to your back? Lol.
I was thinking domestic places and close quarters businesses. Also there is a noise consideration. Do they have large battery packs that can output enough for a shop vacuum? Lets say 2 hours tops of cleaning. If it doesn't exist about how heavy would it be? Perhaps it can be dolly-ed around like...
For those that have to vacuum large spaces often have to use many different outlets and worry about running over their own cord. Is there a battery pack one can strap to their back to power a vacuum cleaner? Or would that amount of power tide to a person be dangerous?
Yes, this is the time crystal I am referring to. And the only reference I can offer to needing to add energy to the system is from a YouTube video which I'm told isn't a good source, so I didn't include it.
I was initially under the impression that time crystals are in lowest energy state and neither gain or lose energy. But other sources suggested they might require a bump in energy after a while to keep going?
So you're saying life was possible between about 2 billion years after big bang and the 11.8 billion years after? Are there predictions of when there won't be enough energy left in the universe for life to be possible?
I am just curious about the elemental level because I was wondering if the universe has any favoritism towards certain biological configurations as well. I know life itself wasn't possible for most of the universes' history, but I am wondering if there is anything special about what exists now...
