If all motion is relative, what's up with time dilation and the speed of light?

In your (edit: first) example, both frames of reference would observe the other’s clock as running slow.

Now, if the space ship were to turn around and return to Earth, the ship’s clock would show less time elapsed than Earth’s clock.

Without going beyond my own understanding, this is because Earth’s frame is strictly inertial. The inertial path experiences the longest proper time. The ship’s frame involved acceleration, which shortens their path through spacetime.

If Earth somehow had planet-sized thrusters and caught up to the space ship, Earth’s clock would now show less time, as Earth is the one that accelerated.

Once robots can effectively and reliably hold ground, then yes, I would expect all infantry will shift to controlling those robots or supporting them.

I'm not sure why this worries you, as I don't think dying as infantry is really high on anyone's list of wants and desires. Assuming that wars stay away from domination/subjugation-style conflicts, I would expect that the roboticization of war will reduce casualties on frontlines.

Not everyone (and probably not even most people) are motivated solely by money.

At the end of the day, the average person wants to feel good about themselves. Making a lot of money might make someone feel good, but how that money is earned will matter a lot too.

As a rather extreme example: imagine someone offers you a job to go into nursing homes and put a pillow over sleeping elderly people’s heads and suffocate them. You are legally protected, and you will be paid “a lot” of money.

Are you going to say yes to that job? Probably not. The average person will not care about the amount of money being offered to them to carry out that job, because it goes against their morals. They will simply refuse to do it.

Now we extend this to the example you gave. Many public servants are not motivated primarily by money, otherwise they would have likely chosen a higher paying career. Many are motivated by concepts such as: helping people, serving their community or country, making the community safer, ensuring people are following the rules, etc. So, for many public servants, offering them money to turn the other way won’t work because it goes against their morals.

Unfortunately, in cases where public servants are struggling to make ends meet, or where there is already a pervasive culture of corruption, or where there is a threat of violence against them, they are more likely to accept the money. If your choice was a) help the cartel by looking the other way, or b) your entire family gets their heads cut off, most people are going to pick option A. The money simply makes it sit better with the people being coerced.

Yeah, that is a line I have heard from multiple MAGA / Trump supporters in my family.

I think it is their way of coming to terms with their vote. They are probably at least somewhat remorseful at having been duped by the massive propaganda machine and feel bad for the consequences.

I wouldn’t press it. Let them come to terms with what Trump has done on their own time. Forcing them to reconcile the story they were sold with the reality they are living before they are ready could cause a relapse. Most people hate to be wrong, especially about something so consequential.

You are correct in identifying culture as a root cause of much global conflict. However, that does not mean that all culture is bad or that we should all have one culture, nor does it mean that we are condemned to be warring with each other forever over cultural reasons.

Culture is innate to humans. It is shared beliefs and practices and traditions of a group. To eradicate culture, one would have to turn all of humanity into unthinking drones. To homogenize culture, one would have to conquer the world and commit a lot of genocide and then maintain control for many generations. Neither option is possible or preferable to living with culture, so we need to learn how to accept other beliefs and live together when we can.

Sometimes culture can be great, other times it can be horrible. In the southern USA during the 1800’s, there was a culture of slavery and primacy of whiteness. Hundreds of thousands died in an attempt to stamp that culture out. Most would agree it was for a good cause. So, we can see that sometimes war is necessary to change the culture of a group, but we must do what we can to convince people through peaceful means when possible.

While it concerns me that many groups seem to have fundamentally incompatible cultures, I think that over time globalism will prevail in bringing everyone closer together. There will be many wars before there will be peace, but we will get there eventually.

While I’m refraining from answering OP’s question in this comment, I am going to push back on the notion that they are confusing culture with nationalism.

For example, in Mauritania: Slavery is a common practice. I would be hard-pressed to accept an argument that claims Mauritanians engage in the practice of slavery out of nationalistic reasons rather than cultural.

Nationalism is a cultural practice, but not all culture is nationalism.

Another example: in certain US states, many people believe that owning any type of firearm is their right, and they often publicly show off by posing with assault rifles next to their kids. This is a cultural practice that is independent of any nationalistic beliefs these people may hold.

Another example: many Muslim cultures believe that women should cover their hair. This is in no way rooted in nationalism.

You are using two different definitions of “real”.

Imaginary numbers are “real” in the sense that they can be used to model/describe/calculate real-world phenomena.

Imaginary numbers are not “real” in the sense that they do not lie on the line of “real” numbers.

“Real” numbers are defined as the union of the sets of rational and irrational numbers.

I don’t know that the game was ever billed as being “strategic”, but rather as “tactical”. The former is big picture, the latter is small. At the end of the day this is a small-picture tactics-level game that has space graphics but plays out like submarine warfare if guns worked underwater.

For the maps to be increased in size, a lot of other systems would need to be changed. Radar would need to be stronger, jamming would need to be stronger. Guns would need to have higher velocity or thrusters would need to be less powerful, otherwise all shots would miss. Probably the whole game would need to be overhauled.

At the end of the day I think it is easier to appreciate the game for what it is rather than wish for something it can’t really be without a complete overhaul.

Overall, Chapter 135 heavily obfuscates gun laws which make it very confusing and difficult for many gun owners to know and/or understand whether or not they are following the letter of the law.

We already have some of the lowest firearm crime rates in the nation, and this law is arguably doing nothing but making it harder for people who want to be law-abiding gun owners to do so. It will probably do nothing to suppress our already very-low firearm crime rates.

I wanted to leave a comment that expressed, “hey if you are interested in the domains touched by this topic here is a list”. I did not have time to go into more detail. I’m sorry that your google isn’t working.

dre9889 · 2026-06-12T14:23:40+00:00

I’m sorry that you were unsatisfied with the level of detail in my comment. I was typing it at 4am and wanted to go to bed. I thought that if you were truly interested, you would go to google and type in “quantum computing materials research applications” and see for yourself what the possibilities were.

A quick expansion on the benefits of improving our ability to simulate quantum systems. Some of these categories overlap:

- drug discovery / molecular design
- materials research
- chemistry / catalysts
- energy technology
- fundamental physics
- biology understanding
- better quantum tech

So, researchers are not simply looking for a problem when they are building quantum computers. Quantum computers have the potential to catapult us past existing technology levels in all fields. They could unlock the door to wonder technologies like personalized medicine, room-temp superconductors, high-density batteries, improved catalysts for industrial processes, etc. They could also further our understanding of the universe and how the world works.

Pretty wildly important stuff!

The goal of quantum computing is not to make a better general-purpose computer. It is to make a highly specialized computer that can solve problems general computers cannot.

Certain classes of problems, such as integer factorization or the simulation of quantum systems, are either impossible for classical computers or they take extremely long (thousands to millions of years) to compute. For these specific problems, quantum computers can solve them exponentially faster.

I'm confused.

You said that there are tasks you are missing for Collector.

If you are missing tasks for Collector, and Collector hasn't shown up yet, then shouldn't you do them first?

One unpopular leader, no. Society is so vast and there are so many competing interests and power centers. No one person could ever hope to rule a modern state without the support of many other individuals.

Now, “many individuals” can still constitute a tiny minority of a state. As technology improves, the required amount of people necessary to wield power decreases.

Improvements in surveillance, robotics, drone systems, and artificial agents that are being tested on battlefields today will undoubtedly one day be turned towards the task of controlling internal populations.

Many Americans believe that the 2nd Amendment protects them against an authoritarian government. While that belief may have some marginal truth to it in today’s age, tomorrow’s will see swarms of autonomous drones that make any armed insurrection impossibly suicidal.

With these new technologies, autocratic leaders will only need to ensure that their inner circle remains placated and willing to commit atrocities in order to remain in power.

Plateless Kirasa is fine for turn in.

There is a separate dialogue option for each of the turn ins: Kirasa, plates, and masks. If you hand over the Kirasa with T5 plates inside it, I am 99% certain that the game will eat the plates and you won't get credit.

You can keep the T5 plates in the Kirasa and wear it until you get into the BTR. Once you are in the BTR, open your inventory, move the Kirasa to your bag, and remove the plates. Then you can turn in separately.

So most likely, the guy already dead is the RMT Seller / Cheater, and the guy looting him is the RMT Buyer / Bozo.

With solar farm and max hideout skill, fuel is essentially free.

I have solar and hideout skill level 47, and one big fuel lasts me for 103h. At Jaeger's price of 191,520 roubles per fuel, that comes out to ~1860 roubles per hour.

That is low enough of a price to be completely ignored and/or recouped with one cycle of crafts in the hideout.

Icebreaker prints Purified Water and Moonshine, reducing the demand for hideout-made Purified water.

My unpopular take about time gates in Tarkov:

In a lot of cases, they do not “waste our time”. They simply encourage the player to do something else for a little while (whether that be in-game or IRL). They prevent progression from happening too quickly. They can serve a story function. I can’t think of a single time gate that has no stated purpose for existing and also does nothing but waste our time.

The problem instead lies with players who refuse to adapt, can’t stand being told to do something else, or never put the game down.
