How do I reply to advices from people who care about me?

The common denominator seems to be me. When people who care about me give me advices, I often do one or multiple of the following:

  • Simulate it in my head and conclude it wont work for me, then say it out loud "wont work because a"
  • Think about the idea, then reshape it into one of my own (so a heavily altered version or alternative)
  • consider that "maybe this advice is solid, but I want to properly study and research it before starting to act on it at all"

What I dont do:

  • blindly follow advices (unless I really have to)
  • be kind of dishonest like "thats a great idea it will help me" when my actual mind is "this wont work"

I'm autistic and very analytical and everything has to be logically whole and consistent for me, and I also am perfectionistic and afraid of doing things inefficiently so I always... always want to arrive at the most complete theory possible before starting any physical action.

This seems to hurt a lot of people.

How do I better respond to advices from loved ones if I don't want to blindly do things I have no understanding of?

Does space not expand, or expand slower, within strong gravity or within black holes?

First to clarify, I literally mean the space. Not the distance between things.

Reason its relevant: my other post, which people seem to not fully grasp my question of and theyre saying my big black hole breaks the laws of physics but I have no clue which law would be broken.. https://www.reddit.com/r/blackholes/comments/1tg7dj0/what_would_happen_if_an_extremely_big_black_hole/?sort=new

If pbject is further away from the singularity than the cosmological horizon, but still necessarily has to travel to the singularity due to being trapped int he event horizon, then 1 of 3 things must be true:

  1. It travels faster than light, which is impossible.
  2. The cosmos within the event horizon expands slower or doesnt expand at all
  3. Both. (which is impossible)

So the only conclusion I can come up with is number 2. But is this true? Or is there another explanation for how the object would reach the singularity?

Because sure you can say "the law of black holes says it must and will reach the singularity", but that doesnt explain how that happens exactly.

What would happen if an extremely big black hole has a bigger event horizon than the distance where light cannot reach you because of the cosmos expansion?

So imagine

  1. Extremely big black hole
  2. An object is so far away that due to cosmos expansion it cannot possibly reach the black hole, even at lightspeed.
  3. The black hole is so strong that its event horizon still reaches that object and consumes it.

Black hole logic says: the object must fall towards the singularity. Cosmos logic says: the object will only be further away over time, due to the rapid expansion of the cosmos inbetween the 2.

So is this a paradox or is one of my assumptions wrong?

The only "logical" thing within my assumptions that I could comeup with, is that

  1. inside the horizon, time seems frozen. But does thatapply to the cosmos expansion too? If yes, it would perfectly answer my hypotheticalquestion.
  2. The object should appear to be not moving, because its in the eventhorizon. But the distance of it increases with the singularity which means that the cosmos expansion should result in the object eventually being outside of the black holes horizon, in finite time for its own perspective and MAYBE also in finite time for the extra observer.

I ask the hypothetical question mostly from curiosity but also to gain a deeper understanding of the underlaying mechanics.

Why doesn't the gravity from a big mass "dent" the eventhorizon of a black hole?

From my previous post on r/physics that I poorly worded and used 2 black holes as exampel instead of 1 + a planet or thing (not so smart)

In the photo I made theres the green circle which would be the event horizon of a black hole and then the blue circle represents a planet with strong gravity.

Because it does gravity in the opposite direction, does that mean that the total "net" gravity towards the singularity is locally weakened and therefore the horizon shrinks locally?

If not why not

u/catboy519 — 5 days ago

2 black holes eventhorizons overlap like a venndiagram. What happens to an object perfectly in the middle?

My whole idea is based upon the fact that if youre perfectly inbetween 2 equally sized black holes, the net gravity has zero effect on you.

Imagine a black hole right and left. The net gravity is zero when you are perfectly in the middle. Ofcourse if you move forward, you will start getting a backwards pull. But that alone should be weaker than, if there was only 1 black hole.

So if youre inside the event horizon of a black hole but then another black hole spawns right next to you on the other side, does that effectively "shrink" the event horizon based on the shape of a venndiagram, which means that technically you aren't traveling out of the event horizon but rather the effective event horizon shrinks through you, resulting in you being outside of it again?

Its 2am 1:49am here so maybe I'm not thinking too bright but I do really think my idea makes sense

Lets define "event horizon gravity" (where light doesnt escape it) as "1g" (1x the gravity) If you are perfectly between 2 black holes then you expecience 0g. And if you move forward while avoiding right or left, you will experience some backwards pull but due to the geometry of the circles you won't expecience 1g or more so you technically should be able to escape the black holes

Missing deadlines and appointments is normal routine for me...

And I fear this will strongy affect my life.

I went to an adhd support group where literally everyone has adhd, yet I WAS STILL THAT ONE PERSON WHO WALKS IN THE LATEST..

Fuck me, fuck me and my disability, why does my adhd have to be so extreme that I can't decently and reasonably function?

If I didnt live in my parental house or have a disability income which I luckily do, I would be 99% certainly homeless due to being unable to take care of myself and my problems. Now adhd isnt the only problem I face but it is very extreme!

How can I cope when medication doesnt quicklywork?

Why shouldnt we eat <1200 kcal?

Its mostly a question of curiosity. Suppose I eat

  • Enough micronutrients
  • Enough protein and my body has fat
  • Drink enough water
  • 400kcals which purely consists of the protein in my food.

Then why should that be a problem? If my body needs 3000kcals on a given day, it can get this from 2600 to 3000 kcals of fat stored in my body and 0 to 400 kcals of protein from the food.

And since its possible to live a healthy life with zero carbs anyway that proves the body can fundction with just fat and protein as fuel.

If people on a zero carbs diet want to eat more or less calories they do so by eating more or less fat and protein.

  • Eating more fat doesnt help fuel the body, because the body already has sufficient stored fat anyway so nothing changes.
  • Protein alone you dont need to eat so much of it that it is worth 1200kcals.

Is my reasoning wrong or are my assumptions wrong?

So impatient for my driving lesson and to get my Drivinglicense!!

I'm 26. I don't have my license for one simple reason: For a long time Ive thought that a license is not worth the money.

If only the adults would convice the 17 to 25 year old me why a license is fun and important, I would probably have one by now. I dont know why no one ever pressured or convinced young me to get one.

Every time I'm riding my bike in the heavy rain seeing that 99% of other traffic is cars and other closed vehicles, it makes me jealous its not fair why do they get to have comfort and me not.

So ive signed up for drivinglessons a couple of months ago... only to find out that a lot of driving schools in NL are busy and overbooked and I needed to wait months before I can even get a mocklesson!! And then even then its often at most 2 hours per week, which means that going by 20 to 40 hours required lessons it would take me 10 to 20 weeks.

Why is it so hard? I want my license NOW but I have to wait for months due to fully booked driving schools and the delays with the exams and all this bs

Yea I'm mad because I should be allowed to drive just like nearly everyone else, the process to get a license shouldn't be have to take so long..... unreasonably.

hOwTo Nail my driving lesson?

I will be getting driving lessons soon. 26 years old in Europe, I want to get my DL license asap with the fewest amount of lessons. Ive been watching some vidoes from different drivingschools to got an idea of what a drivinglesson looks like.

Is there any way or form of preparation that I can do, other than absorbing more theory and cognitive understanding? Obviously I know that "driving secretly on a parkinglot" is a thing but I'm not going to be doing that before my lessons.

Has anyone here experience with rushing a license?

Would a magic observer in a black hole experience that the hole has evaporated?

With my limitedunderstanding I reason:

  1. It would observe finite time during the fall
  2. Time would stop so therefore it wouldnt have a consciousness.
  3. But the black hole evaporates
  4. If the black hole is no more, then time should resume and continue and therefore the consciousness also.
  5. So the subjective experience should be that the blackhole disappears instantaneously?

Emotionally crave the gym but logically don't wanna do that?

When I logically think about it, I don't wanna do strength training. I'm strong enough to do everything from my daily life so being stronger isnt useful. Strength training would also mean I have to eat much more protein, which is in itself a big challenge. And if health is the goal I can just walk or run.

So not much of a reason to go to the gym there.

But something about strength training just emotionally attracts me. The feeling of doing that last rep before failure, the feeling of weak shaky sore muscles after training, I always loved that a lot when I went to the gym as an obsessed teenager.

But how can I enjoy a hobby when my logical mind says "we shouldnt be doing this"?

Should I? Or is there no point?

Another part of the post: I crave stimulation right now and I feel so bored and empty, not sure what to do...

Electromotor Efficiency Calculation question!

If an electromotor spins at a speed where it generates 30 volts back emf and theres 5 ampere running through it, does that mean 150 watts mechanical output?

Or is there somehow any further losses?

  1. You supply 31 volts
  2. Motor with 30 volts back emf will draw 5 ampere
  3. Obviously theres 1 volts loss because 31-30=1, but are there any further loses beyond this?

And if there are, how? Current doesnt "drop" like voltage does, and the voltage drops to 0 volt anyway (where it goes from motor back to the battery minus) right? So if any loss occurs how does that work in terms of voltage and current

mY guess is that if you supply 5x31 = 155watts, the motor would generate 5x30 = 150 mechanical watts.

However such high efficiency feels unrealistic so surely I must be missing something...what?

ElectroNerds, is my system electroefficiency calculation correct?

  1. my ebike tops out on 21.1 mph or 34.0 kmh
  2. the battery's maxvoltage is 42.0 volt.
  3. With full battery, at 18mph or 29kph, my bike can run at maxpower. From that point, going faster results in the current dropping due to the back EMF. (motor kv rpm limit, not software)
  4. At that speed, back emf should be about 6/7 which is 36 volts.
  5. Does the motor's back emf directly correlate with how much power it produces? If a motor is spinning with lets sat 30volt backemf and theres 5 amps going through the motor, does that mean 150 watts mechanical output? This is something I'm unsure about. 6 If it does, then going 18mph 29kph at maxpower would mean there is only 14% efficiency loss in total, meaning 86% of the battery becomes foward movement kinetic energy. That feels unrealistic.
  6. if it doesnt, then doees that mean inside the motor itself the voltage drops further or how does that work?exactly

Hub motor smallbattery hill strategy.

Sharing my strategy idea and asking what you guys think of it.

  1. Downhill: just roll. 0 energy usage needed
  2. Flat(or very slight grades): pedal
  3. Uphill: use the motor too, about 70% or 80% power seems reasonable.
  4. Extra Steep parts of the hill: walk.

Ofcourse this is pretty simplified and I therefore wonder if any more nuance exists. Can I do anything more advanced to improve range and performance?

Does anyone here have experience with low power hubmotors and small batteries in the mountains?:) 1431

Why should I start right now and not 1 second into the future?

Please convince me with all sorts of different unique but powerful perspectives.

For example:

  • Why should I go to bed right now, instead of watching 1 more youtubevideo of 2 minutes that I had already seen or opened or looked up?
  • Why should I start the tasks on my todolist RIGHT NOW and not 5, 30 or 60 minutes later or just tonight or tomorrow or next week?
  • Why should I be on my way towards some place I have to be right now, instead of taking 1 more minute to do something quick that I want to do before leaving?

I struggle with doing things that must need to be done ASAP, but without a clear deadline. Its not like going to bed 5 minute later means "deadline missed so no sleep today". The problematic fact is ofcourse that this logic always applies so therefore it results in me going to bed sometimes many hours later than what I had originally intended.

I'm intelligent and logical so I can perfectly rationalize everything I do and come up with so many reasons for why I procrastinate and so on...

can someone convince me logically why waiting even just 1 more second to start those "asap" things, is not worth it?

Or better question: how do I convince my nervous system and autopilot that going to bed right now is better than waiting just 1 minute more minute for another small specific thing I wanted to do?

Battery +12 degrees c when slowcharging normal?

My phone has fastcharging turned off in the batterysettings. My phone has been having some overheatingproblems for a long time now that I feel like, but today I was just slowcharging my phone without even using it (screen was black the whole time) and when I woke the phone up and checked the batterytemp, its +12degrees hotter than the roomtemperature.

That normal? For slowcharging on a phone that also supports charging twice as fast?

I'm a racecar with a tiny little fueltank.

My fuel tank or battery, is just normal. Like anyone elses. But when you have a mind that races like mine does, the fuel is used up fully within 5 minutes only. Refueling takes 10 hours of sleep by the way. Wait maybe that means I actually have more energy but that doesnt matter because its not effectively and efficiently used.

I want to ravel the world. I want to learn multiple languages. I want to make extra friends. I want to start a big business and change the world. I want to be a politician. I want to be rich. I want to find my dream job and dream hobby. I want to master things and be so good at things that I'm the best of the world at it.

Now one or two of those are surely possible. But everything together nah thats not possible I'm trying to race 100 tracks at the same time thats not doable?

Logically I know that the rational response is to just drop things and relax. But my emotional brain won't ever shut up, it will keep nagging and nudging me about all those things I should be doing, want or need to be doing. All those things that I definitely should not or cannot miss out on.

Maybe I don't necessarily have less energy, but I use more of my energy in ways that normal people dont use their energy and therefore it looks like I have no energy. "I have no energy to brush my teeth" might actually mean "I have spent so much energy on other things that now I dont have any left for brushing my teeth"

How to not neglect myself and my goals and loved ones?

Because I currently neglect the 3. My energy is so low, so extremely low, that even brushing my teeth is too much. Ive been rarely brushing for years and now I finally gotten a cavity.. that was bound to happen wasnt it? and I'm still not brushing my teeth! How silly am I!

So I neglect myself. I neglect loved ones. I neglect my goals. I neglect my todolist. I basically just wake up, passively exist, then back to sleep.

At this point my burnout has become a very big disability. Maybe a person with zero limbs but a healthy mind and energy can do more work and get more achievements done than I can currently. I might be wrong but thats why I carefully say maybe.

Ive been in this for about 4.5 years now. Will it ever get better?

Will I ever be able to function normally, brush my teeth, spend time with people, do things on my todolist and so on?

What if I dont get better then whats the point of just passively existing letting deadlines terminate themselves?

How to reproduce controllerbug/protectionmode?

Since my ebike got a new controller, at random times it will bug or enter a prorection mode maybe.

What I notice:

  1. At a random moment, my ebikes power gets limited to a very low amount. Could be 10 seconds after starting a ride, could be after an hour.
  2. For a random duration this persists. Could be a few seconds could be 20 minutes.
  3. At another random moment the power goes back to normal.
  4. At any time if I restart the bike, the power is back to normal instantly.
  5. I have a feeling that this happens more often when I'm either braking or rolling over rough rocks terrain.
