That said I watched Elon Musk's Space shot yesterday.  I can say without a doubt and 100% certainty that part of it was faked.
...
At 4:26:17
the booster is dropped.
it is at a height of  84.3 kilometers
it is at a speed of 6706 kilometers per hour
at about 4:28:37 they show it above earth and if you watch you can see it falling

It's not clear to me what you are saying. This is basic high school physics. Just do the math.

6706 km/h is 1863 m/s. The velocity of a falling object increases at a rate of 9.8 m/s/s. If the booster is traveling straight up at 1863 m/s, then it would start falling after 1863/9.8 =  190 seconds, or about three minutes. The booster is most certainly not traveling straight up, so the time will be less.

The distance that an object falls is 4.9 m/s2 (assuming no air friction), so the time it takes to fall 84 km is sqrt( 84000/4.9 ) = 131 seconds, or about two minutes.

Now, the complete question is how long does it take for an object at 84000 m and traveling at 1863 m/s take to hit the ground (assuming no air friction and no thrusters). This equation describes the question:

0 = 84000 + 1863t - 9.8t2

The answer is 421 seconds = 7 minutes.

All of these numbers are close to the timeline. There are no impossibilities occurring here, and while it really sucks that we couldn't see the landing as it happened, that is not evidence of a hoax. You seem to have fallen victim to the most common flat-earth fallacy: if you don't understand something, then it must be impossible.

Edit: fixed math

1923  Other / Serious discussion / Re: [random question] what wind speed does it take to move a person? on: May 28, 2020, 10:42:26 PM
Knocking somebody over is all about balance, so there really is no good answer to that question. However, if you want to know the wind speed necessary to lift a person, then here you go:

If you are not afraid of math, this will tell you: Wikipedia article on drag

If you don't want to deal with math, then the answer is 200 km/h. That's the terminal velocity of a skydiver.

As for severity, both tornadoes and hurricanes are common in certain areas of the U.S and cause major damage.

There are an average of about 10 major tornadoes (F4 and F5, with wind speeds exceeding 350 km/h) each year. (https://www.ustornadoes.com/2012/04/10/violent-f4ef-4-and-f5ef-5-tornadoes-in-the-united-states-since-1950/)

Likewise, an average of about 6 major hurricanes (catagories 3, 4, and 5, with wind speeds exceeding 178 km/h) hit the U.S. each decade, or roughly one every other year.  (https://www.nhc.noaa.gov/pastdec.shtml)

1926  Bitcoin / Bitcoin Discussion / Re: Questions I have about Bitcoin on: May 26, 2020, 06:45:32 PM
Is bitcoin really viable as a peer-to-peer electronic cash?

Due to high transaction costs and slow transaction speeds, how can we ever use bitcoin to purchase, for example, a Sprite and a bag of potato chips at a gas station? If I want to send a micropayment, for example, of 1000 sats on-chain I can pretty much forget about it because miners can’t afford to and as a result the transaction hangs out in the memepool indefinitely. I had a lot of hope for lightning network, but I am now starting to have doubts about its long-term success. What happens when someone using lightning wants to settling a microtransaction on the bitcoin blockchain?

Can you use coins and paper notes to pay for an online order? No. Does that mean that coins and paper notes are not viable forms of cash? No. The fact that Bitcoin is not the best option for certain kinds of transactions does not mean that it is not viable.

The proper question is, "are there any kinds of transactions in which Bitcoin is a viable option?" The answer to that is probably yes.

Isn't bitcoin mining dangerously centralized? What if in the future there is a terrorist attack by government or other criminal orgs that involve bombing or burning large bitcoin mining facilities?

There are so many bitcoin mining facilities that I don't think that is a real danger. There are many more bitcoin mining facilities than there are Federal Reserve offices.

Satoshi writes in the bitcoin white paper that we propose a solution to the double spending problem, but has this really been achieved? Double spends are still possible with a 51% attack, so what solution to double spending has been achieved? Can't large mining pools conspire to attack bitcoin?

Keep in mind that every monetary system is vulnerable to some kind of attack. There is never any perfect solution.
1927  Other / Serious discussion / Re: Trap of logic. on: May 25, 2020, 11:38:46 PM
Sometimes I feel that we are getting trapped more and more, day by day into the trap of logic. Though in writing this I must use logic but not logic only. There is something far more powerful that drives us, you can call it emotions but it is in the domain of irrationality and trying to name it is a futile effort of logic.
Logic is not out there it is a lens that we have decided to pick. For logic in order to exist there must be preexisting irrationality. We are the product of randomness, we are the children of irrationality free from any limitations not matter how logical they seems.  

Logic is a way to organize our experience. It is not the basis of that experience.

The problem is that now I can't transfer from this wallet because it's BIP38 encrypted and Blockchain.com site can't read this kind of adress.
I tried to use this site to Decrypt the adress but it doesn't match with the right one.
Is there another site from where I can transfer using a BIP38 encrypted key to another adress? Is there any other way for me to find the matching private key from the BIP38 key?

Both the Samourai and Mycelium wallets on my phone can sweep BIP38-encrypted private keys. Electrum cannot. However, I'm confused about your question because Blockchain.com does support BIP38-encrypted private keys. I just tried it.

1931  Economy / Exchanges / Re: Started selling on paxful & my bank just called to say my account is closed on: May 22, 2020, 12:05:01 AM
A financial analyst from us bank called me today to tell me that my account will be closed because of funds being deposited into my account through zelle were deemed as fraudulent. ... Sites like paxful are completely legal. I was vending bitcoin and making transactions through zelle, only releasing bitcoin after funds were deemed as deposited. How is this possible? How was I supposed to know that the money coming in was fraudulent?

1. It is possible that the funds were sent to you from a hacked or stolen bank account.
2. It is possible that the buyer lied to get their money back.
3. There is a common scam called a man-in-the-middle scam (by traders). It works like this:
  • A. Scammer pretends to be selling something for X dollars and finds a buyer, Alice.
  • B. Scammer contacts you and agrees to buy bitcoins for X dollars.
  • C. Scammer tells Alice to send X dollars to your bank account.
  • D. You receive X dollars from Alice and you release the bitcoins to Scammer.
  • E. Scammer disappears with your bitcoins.
  • F. Alice knows your account number and believes that you are the scammer.

The way to avoid these situations is to get KYC information from your buyers and/or to check the sources of the funds sent to your bank account before releasing the bitcoins.

...the details of extra-nonce parameter for the relevant transaction disprove that totally.

Honestly, it doesn't really prove or disprove anything. The nonce theory suggests which blocks were mined by a single computer, but Satoshi easily could have been mining on more than one computer.

Craig wright is a  bully, detestable liar, he is definitely not Satoshi

I don't think that CW is Satoshi, but Satoshi could be a bully and a detestable liar, too.

Your images imply that the master keys are derived from the entropy used to generate the seed phrase; however, the phrase itself is used as input to the PBKDF2.
1935  Bitcoin / Bitcoin Discussion / Re: There's something Satoshi didn't think of. on: May 19, 2020, 11:53:17 PM
The price of Bitcoin should rise, otherwise mining will become unprofitable, and not needed by the vast majority of those who mine it now. A decrease in the number of miners can again lead to the problem of network congestion, when transactions have to pay huge amounts.

I recommend that you read more and post less. Your beliefs have already been addressed here and have been shown to be wrong or at best unsupported.

The originating patent doesn’t suffice?

That is a patent for a hash algorithm that was in use long before Bitcoin existed. To say that the intention of developing SHA-2 was for Bitcoin is ridiculous. Look at this statement from NIST:

March 15, 2006: The SHA-2 family of hash functions (i.e., SHA-224, SHA-256, SHA-384 and SHA-512) may be used by Federal agencies for all applications using secure hash algorithms. Federal agencies should stop using SHA-1 for digital signatures, digital time stamping and other applications that require collision resistance as soon as practical, and must use the SHA-2 family of hash functions for these applications after 2010.

Any rebuttals that you may have that are based on other conspiracy fantasies are equally ridiculous.
1937  Bitcoin / Bitcoin Discussion / Re: There's something Satoshi didn't think of. on: May 18, 2020, 12:38:57 AM
...
So in a few words only if miners can afford from their rewarded BTC, the mining cost. Only then bitcoin will survive. Due to halving, price will rise because if a miner finds pricy his equipment now, then he will retire 4 years later.
...

There is no issue. There will always be miners. Don't forget that people were mining bitcoins when the block reward was worth less than $1.

The idea that all miners will stop mining if the price is too low or the difficulty is too high is naive. No matter what the price is or what the difficulty is, some miners can make a profit and some can't.

I do not think that at least someone owns this trademark, and is unlikely to ever own it.

Mark Karpeles trademarked "BITCOIN" in the E.U. and Japan for some kinds of equipment, as well as IT and telecom services in 2011: https://euipo.europa.eu/eSearch/#details/trademarks/010103646

"BITCOIN" is trademarked in the U.K. for clothing and beverages: https://trademarks.ipo.gov.uk/ipo-tmcase/page/Results/1/UK00003279106

There was an attempt to trademark "BITCOIN" in the U.S. for bar glassware and utensils in 2013, but it was abandoned after being challenged: https://trademarks.justia.com/861/35/bitcoin-86135516.html

1940  Bitcoin / Bitcoin Discussion / Re: Bitcoin Halving , and its Effects on: May 16, 2020, 02:16:38 AM
I think that to sustain the mining rigs price will go up because almost 30% decline in btc mining companies shows that if price doesnt go up , it will be difficult for the miners to sustain , and it can impact in high transaction fees.

You have it exactly backwards. If the price goes up (doubles), then the miners are sustained. If it doesn't go up, then some miners will have to shut down some or all of their equipment.

Transaction fees are not determined by the amount of mining (in the short term) because the amount of space in the block chain is held roughly constant by adjusting the difficulty every 2016 blocks. The block chain throughput is temporarily lower now because of the halving and that may be affecting fees, but that will change in a couple days when the difficulty is adjusted.
