The name of the user shows just how dark this individual is. Please see https://www.fairobserver.com/world-news/incels-alt-right-manosphere-extremism-radicalism-news-51421/amp/

Beware of these guys.

General Science / Re: When do YOU die in a many worlds interpretation?
« on: Yesterday at 12:38:15 »
You die. If you are buried then other lifeforms feed on you. They consume your energy for their own use. If you are cremated all your energy goes up a chimney. This continuous cycle continues until all species become extinct, the planet loses its atmosphere and water. Then the sun expands to consume the planet. Ultimately many worlds are consumed this way until the ultimate heat death of the universe. And they all lived happily ever after.

Quote from: alancalverd
alien tissue rejection manage to happen so quickly
It takes a few days for your immune system to realise that you are under attack by an alien virus and mount a response.

A transplanted heart is not actively attacking you, but the surgery certainly looks like some kind of attack. So a few days to react seems about similar (if you aren't taking your anti-rejection medications meticulously).

In fact, your body does not wait for the attack, but is pre-primed to react to anything that seems alien. There are a bunch of randomly-generated antibodies floating around your system. As a child, your thymus removes the ones that react to "self", leaving all the others to detect anything that looks "alien". As soon as anything "alien" appears on the scene, one of these pre-built antibodies will latch onto it, and start a cascade of escalating immune responses.
See: https://en.wikipedia.org/wiki/Thymus#Function


Is there anything in childhood diseases that could prevent the complete removal of self attacking antibodies? Some diseases actually cause the body to attack itself. Could there be a clue in what you said?

First off life-wave was a Freudian slip typo. It's in regards to a theory about life sending information with waves of this nature. I think DNA's shape looks a little "coincidentally" like a circularly polarized photons wave-function. Lastly bud, don't know why you are answering the question with such a tone as you have no idea who I am, and it was a question, but I have taken QM classes at my University before I am a physics major. I'm pretty sure you wrong that wave functions can't be specific shapes btw

I can infer from what you say that you don't know what you are talking about.

« on: 03/12/2019 06:55:42 »
For a start photons do not have a life wave. They have a wave function. The function has to be continuos so, no, it can't be heart shaped. That does not describe a wave. You need to learn about the probabilistic nature of quantum mechanics before making anymore rash statements.

Physics, Astronomy & Cosmology / Does quantum bayesianism have anything useful to say?
« on: 01/12/2019 17:26:35 »
See https://en.m.wikipedia.org/wiki/Quantum_Bayesianism
Does this clear up the mysticism of many-worlds and other such interpretations?

Physics, Astronomy & Cosmology / Can we detect acceleration in free fall?
« on: 19/11/2019 19:11:44 »
Well this is not the question you might think it is. If a spacecraft is falling freely towards a gravitating body, and then starts accelerating towards the body, would an accelerometer show the acceleration?

I have not seen anything about this online. I would say it would. Is there any observational evidence anyone can point to? Have you tried this personally?

General Science / Re: Herb and marijuana anxiety
« on: 17/11/2019 16:58:03 »
BTW anxiolytic refers to a drug that is used to relieve anxiety. But since you like to cloak everything in penetrable jargon I think the explanation was warranted. Not everyone attends med school or swallows a medical dictionary whole.

Actually, thinking about it, discussing any downside might hinder your ability to evangelise on cannabis use.

Did I mention significant psychological damage in that post? It's you who keeps bringing that up. Sounds rather defensive to me. I could be wrong.

Well you obviously didn't read all the page that I linked to. There they discuss how children are ingesting their parents 'medicine'. I don't include them in the category of responsible adults, do you?

Also the page discusses how often people are overdosing themselves on store bought goodies. Decriminalisation is great for the sellers of 'edibles'. Not so much for the ordinary guy. They obviously have failed to meet your high ideals.

The problem is when you spend 28 years hiding from the real world you can lose the ability to think rationally.

So you would be perfectly fine giving daily doses of cannabis to all children over 5 years of age then? It should be beneficial to their psychological development according to your way of thinking.

Of course you know that, since there is a "war on drugs", there is likely to be sparse research on this subject. A good place to start is here https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5260817/

This discusses use in American stares that have decriminalised recreational use. It discusses edibles. It also highlights the sparseness of current research. This is exactly what the proponents of drug use rely on. "Where is the peer reviewed research?", they wail. Kind of dishonest if you ask me.

For anyone remotely interested in research here is a page from the NHS. No one should take anything other than peer reviewed research as gospel but this is worth the read.

People who smoke it daily seem to suffer attention loss.

Such an effect is very much dose-dependent. In responsible users who precisely regulate doses, it actually elicits cognitive effects which are quite the opposite.

~


So you believe that smoking is beneficial? So smoking for 28 years will have no detrimental effect. Well let's all rush into burning buildings and inhale those benefits. OK so that is me being extreme but smoke inhalation does damage. That is not up for debate. Unless you are delusional. I don't believe you are delusional though I am open to the prospect of you proving me wrong.

I think everyone just, on purpose, ignores the significant psychological damage that the drug can cause. Happy Mondays!

Having been a user for the past 28 years or so, I would enjoy seeing your list of "significant psychological damage" that Cannabis use elicits, along with a collective body of peer-reviewed clinical evidence to support such an uneducated notion.

Well if you want to make your brain malfunction try that is entirely up to you. I have seen what drugs of various kinds end up doing to people. They are never the same once they have succumbed. It tends to extract the joy out of them.

New Theories / Re: Destroying the big bang and Hubble .
« on: 11/11/2019 21:06:03 »
The photon sphere is 3/2 times the Schwarzschild radius. That is 1.5 times the radius.
See:
http://hyperphysics.phy-astr.gsu.edu/hbase/Astro/blkhol.html

Edit: This assumes a non rotating black hole. The Kerr black hole is much more complex.

Well, not being willing to converse in English speaks volumes about your confidence in your own ideas. Hiding the discussion from the general readership is not a good look for someone trying to prove they are an honest actor.

I look forward to your reply with great anticipation.

Thanks for the replies. I'll have to compile a list. I do have a book on particles somewhere. I may dig that out.
