Its because from the perspective of the traveling particle (or person) there is no light speed limit or speed limit of any kind. Light is just infinitely fast from its own perspective and travels any distance in no time at all. This can be shown experimentally as well as through theory, without mass it can't experience any changes without outside influence along its path. Neutrinos, for example, change flavors as they travel and thus have mass because they must experience time as they travel. The universe simply ages around photons in an amount proportional to the distance it had to travel. Same would hold for a person in an intimately fast spaceship, the universe would contract to a point directly ahead and behind and be of infinite brightness and the universe would simply not exist at all to the "sides".
Back to your original question, space is larger than we can see, by a factor of around 10,000 at least, we can and have measured this it's called the flatness (or curvature) of spacetime. It's better to think of all points in space time touching at the instant of the Big Bang, then hyper inflation expanded them far faster than lightspeed. We can see the initial quantum fluctuations expanded to bigger than our visible space and imprinted on the cosmic background radiation. These points were essentially torn from each other such that they could no longer influence each other like we classically think. So as time goes on, more and more of these points "reconnect" as time goes on and light can finally catch up with them. So points that are just coming into view now, are ones that haven't "seen" each other in 13.8 billion years. It dosent have anything to do with light starting from here and ending here at all. As time goes on and space starts picking up accelerating expansion due to dark energy, these points will be torn away from each other yet again never (presumably) to classically interact again and our visible universe will shrink. This is a bit simplified but is fairly accurate nonetheless.
They are only hard to see directly and only hard to detect if not feeding or extremely far away. When they suck in large amounts of matter, they are among the most energetic events in the universe and can put out 10-40 times the energy of even the fusion in stars. This allows them to put out the same energy our sun would over its entire life of billions of years, but in only a few moments. So you can see them from farther off than anything else really, but when you are looking 10+ billion light years off they still appear small and hard to detect definitively.
As far as large amounts of gravity, that would only slow down the expansion of space. At the Big Bang space expanded quickly, then gravity has been slowing it down. Only recently in terms of the universe has dark energy taken over and started to increase the rate of expansion again, with a measureable effect that is repelling instead of attracting like gravity.
A photon as a particle will travel in a straight line as you classically think, however it is also a wave and has uncertainty according to Heisenberg uncertainty. If you constrain the photons position, say by emitting it from a point and passing it through an arbitrarily small orifice, cementing position, momentum blows up and spreads it out. This is the source of diffraction in slit experiments.
The size of the universe may in fact be infinite. How me measure this is by how flat space is. Depending on the energy density of space this could be positive or negative curvature, or flat if the energy density is balanced exactly wth gravity. So far the measurement is almost exactly flat, with a margin of error of about 2% so the universe could still be positive or negative slightly. We know with certainty then, the actual universe roughly at least 10,000 times the volume we can see, and we may show with accepted theory one day the universe is infinite but we will never be able to measure it because measurements can't be made with infinite precision. A detailed explanation is here
This is only true until strong AI/androids and general automation become cheaper labor than humans. After that there will be no point in humans working any longer because they cost more than the robots/AI which can do anything a human can. Is this 20 years? No. 50 years? Maybe. 100 years? Quite likely. If nothing changes 99% of people will be out of work and left to die.
First wouldn't be the only tax. Second - as opposed to our current system with the last cut being a truly massive permenant giveaway to large businesses and the 0.1% while almost nothing went to the middle class and those few breaks expire in 2024? It's not a regressive tax, it's equally applied across all purchases and functions like a sales tax except it's levied on the producers, is far easier to track, and is harder to wiggle out from than when you make the customer finally pay. It's the most common tax system used in the world and the US is the only major economic power, if not the only real country at all, without one. If you believe the government is corrupt there is no way forward, no matter what is tried it will only end in the same unaccountability and crushing of the middle and lower classes. But if we head forward sensibly, something has to change. This is going to be far worse than the industrial revolution and that killed the middle class for 80 years.
A value added tax to fund a UBI/Universal Basic Services is another approach and one harder to circumvent with tax or production location loopholes. Say you wanted to implement a UBI of 12k per person per year for adults. That's roughly 3 trillion per year in the US given 250 million on the payroll. Projected US population and projected GDP show that the GDP is outpacing population growth by a large margin. Even if you take inflation into account, the price of goods and services is dropping as automation takes over. You can save money by cancelling other welfare programs, and all that cash would trickle up into the economy as well which has positive benefits. These alone could make a meager straight UBI doable in a 20-40 year timeframe, maybe even 12k/year, if the population and GDP keep growing roughly as expected.
Wait... won't automation and Weak AI/AI bring down the costs of goods and services? What would people absolutely have to spend that money on? Housing? Food? Child care? Education? Healthcare? Access to information? Given the lower future costs it may be best to give out 500 dollars today's equivelant per month and offer free basic housing around the nation, free basic food, free child care, free education, free healthcare, and free basic internet access. The costs of all of these could go quite low in the future and a regulated non profit market like Germany has health insurance or a government run solution could be quite efficient with low overhead if done right. That way the most needy benefit the most with the basic services, and everyone is lifted by the basic income while reasonably well off people will forgo their basic services and pay for better ones.
Wouldn't that render pretty much half of all social media unreadable? The focus on how you can finely tune the threshold is a dead giveaway a little bit tunes it all out.
The paper can be found here. They simply say the mass is equal to the negative the rate of change of (sound in the medium) with respect to the rate of change of (density in the medium) all times the Energy/(speed of sound in the medium). The mass transported is tiny at roughly m=E/(sound speed in the medium)^2. It's basically Snell's law
the ratio of the sines of the angles of incidence and refraction of a wave are constant when it passes between two given media.
So basically the sound kind of bounces off the pressure gradient caused by gravity, lifting the mass of the medium with it (slightly). The authors themselves discuss how it is equivalent to sourcing gravity, how to measure the effect in the conclusion, and mention how the same effect could cause two parallel sound save packets to experience a very slight attractive force.
You lose 15% when two large surface area near field "antennas" are in close proximity (compared to the size of the antenna). This is mostly magnetic resonance coupling. To actually transmit over large distances, the losses become much higher and more dangerous in that foreign objects could receive, conduct, and start bleeding power as heat like a metal handle on a take out box in your microwave. For these reasons there are very limited applications where sending appreciable power over long distances (yards/meters) is viable.
Don't forget the for profit prisons, where under the 13th amendment you can force people to work for free. More often than not these are minorities.
Section 1. Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.
Yep. After reading the headline I thought "well good, with a fully 3-D printed gun the only person he could shoot is himself". But a machined/printed lower and actual functional gun parts makes for a useable weapon.
They should put a warning on it if it's that dangerous.
The main problem is when they put a warning label on each water molecule,
It turned out to have almost as fine a print as your average eula and nobody read them.
I did this when the temps reached -30F without windchill. It's not a dumb experiment, but cold temperatures don't magically negate the fact you are using boiling water which is a scald hazard. There is more energy and more destructive power in a car, and if you back over people because it's crowded and you didn't clear off the snow on your windows or can't stop because of ice you are guilty of being an idiot. It is perfectly ok to use a car if you clean the windows and drive safely.
That said you are correct. Droplets from being thrown will take too long to freeze even at -30. The reason you boil the water is the steam, at -30 boilling water makes a very audible fwooossshhh sound and the steam droplets are cold enough to freeze because of the extremely small size. Cold water won't fwooooshhh and makes much less vapor. I have a mini snow making rig that is comprised of a pressure washer and air compressor, unless it's about -20 or less even the tiny droplets from just a fine spray pressure washer nozzle won't freeze (even then it stinks) you need compressed air to atomize it further and expand to provide nucleation.
As with any actual medical analysis, the details are important, often difficult to understand for people who aren't medical professionals, and sadly often give rise to irrational fears among the population. If you look at the WHO analysis there is a group of people who are at risk for a slightly negative outcome over those in that same subset of people who went unvaccinated. This can be in principle reduced to a positive for society and individuals with a screening test, even if there is a slight false negative result. If you have sources showing this company acted in bad faith, or suppressed research results for profit, I would be interested to hear it. From everything I've seen the pushback is mostly emotional and unfounded.
This sounds good on the outside but fails upon examination. Young children can't be vaccinated, the age they can depends on the specific vaccine, but as a general rule infants are unprotected. The elderly are also at increased risk even if vaccinated. Then there are some few people with whom a particular vaccination isn't particularly effective. Those may be a small minority of the vaccinated population but they often don't even know who they are. There are also a small minority of people with whom there is a legitimate medical reason they can't be vaccinated. Those people depend on a healthy "herd" of people. So when a child contracts a preventable illness through negligence like not vaccinating, then spreads it to the above vulnerable groups, it should be a criminal act because it is clearly morally wrong and injures or kills innocent people. But plenty of poor people choose not to vaccinate, how do you get blood from a stone? How do you compensate for the loss of an infant, elderly person, or loved one who can't be protected? Money dosent fix the emotional loss, nor can properly compensate for the disfigurement or life long health effects if they live.
It should absolutely be a crime against the parents/guardians, yes, but at the same time it can be hard to prove exactly who actually infected the victim and there is no possible way to compensate the damages or in some cases to even get any compensation. That's why I'm in favor of isolating them from society if we cannot make it mandatory (excusing legitimate medical reasons only).
If you can even find a brick and mortar store for electronics parts these days. I live in a city of 2 million and there isn't a single comprehensive brick and mortar store for actual electronic components beyond some through hole mount resistors, through hole mount leds, and a very very few basic semiconductors from the 70s like 555 timing chips or some buffers. Want some actual power mosfets, actual microcontrollers, or SoC? Forget it.
If the encryption is sound (e.g. LUKS with a reasonable password), then that is not possible. Also, who pays for it? The coins in there still belong to somebody.
Hmm, 137 million... no one thought to write another copy down or adhere to any kind of best practices. I bet the password is the same as his TSA certified luggage.
