Since President Donald Trump won the election in November, businesses across the globe have been bracing for higher tariffs — a key Day One promise the president made.
But over a week into his presidency, Trump has yet to enact any new tariffs.
bsme .at
That could change, come 11:59 p.m. ET on Saturday — the deadline Trump set for when he says he will slap 25% tariffs on all Mexican and Canadian goods and a 10% tariff on all Chinese goods.
The tariffs, he said, will be imposed as a way of punishing the three nations, which Trump claims are responsible for helping people enter the country illegally and supplying fentanyl consumed in the US.
Speaking to reporters from the Oval Office on Thursday, Trump said he meant business, especially with his tariff threats on Mexico and Canada. White House Press Secretary Karoline Leavitt also confirmed on Friday that Trump will levy the 10% tariff on China on Saturday.

Should these threats be believed? Yes and no, said Trump’s former Commerce Secretary Wilbur Ross.

The threat of blanket tariffs is likely being overstated, Ross said in an interview with CNN. “There probably will be exclusions, because there are some goods that just are not made here, will not be made here, and therefore, there’s no particular point putting tariffs on.”
Ross, who was one of a handful of initial cabinet members in Trump’s first administration who kept their position for the entire four-year term, said he advocated for such exclusions when he advised Trump on tariff policies.

“We got 53 candidates for anomalies that cannot be well explained, but can’t say that all of them are Dyson sphere candidates, because that’s not what we are specifically looking for,” said Gabriella Contardo, a postdoctoral research fellow at the International School for Advanced Studies in Trieste, Italy, who led the earlier study. She added that she plans to check the candidates against Suazo’s model to see how many tie into it.

“You need to eliminate all other hypotheses and explanations before saying that they could be a Dyson sphere,” she added. “To do so you need to also rule out that it’s not some kind of debris disk, or some kind of planetary collision, and that also pushes the science forward in other fields of astronomy — so it’s a win-win.”
Both Contardo and Suazo agree that more research is needed on the data, and that ultimately they could turn to NASA’s James Webb Space Telescope for more information, as it is powerful enough to observe the candidate stars directly. However, because of the lengthy, competitive procedures that regulate use of the telescope, securing access might take some time.
If Dyson spheres really exist, what could they be used for? “If you picture ourselves having as much energy as the sun is providing every second, we could do unheard of things,” Suazo said. “We could do interstellar travel, maybe we could even move the entire solar system to our preferred location, if we wanted.”
But don’t hold your breath, because the technology and the raw materials required to build the hypothetical structures are far beyond humanity’s grasp.
“They are so big that everything we have on Earth would not be enough to build them,” Suazo added. “Freeman Dyson said that we should dismantle Jupiter — the whole planet (for the raw materials).”
That supercolossal scale probably means that Dyson spheres, if they exist at all, are very rare.

Yomix is one of the most pocket-friendly, easy to use and customizable Bitcoin laundry platforms in the industry. The user-interface is extremely simple and clean, anyone who has never before used any such service too can navigate around and tumble Bitcoins easily. No registration is required to mix Bitcoins on Blender.io Its “delay” feature lets you set delays from 1-24 hours which increases your anonymity by providing a gap between the deposited coins and the outgoing ones. As for the fee, it’s dynamic, meaning you get to choose the amount of fee you’d like to pay, the minimum fee being 0.5% and the maximum being 2.5% with an additional 0.0005%/address. It’s also one of the rare platforms which provides you with a mixing code which makes sure your previous coins do not get mixed with your newer deposits if you do multiple deposits to the tumbler. The minimum amount you can mix is 0.001BTC while there’s no specific maximum amount as their Bitcoin reserve seems to be quite large. It also has a No Logs Policy and all data is instantly deleted as soon as a transaction is complete; and as for the number of confirmations required it’s 3 for your deposit to be mixed by Yomix It supports 8 addresses for each mix so you can further increase your anonymity. In a nutshell, it gives you the power to choose, is fast, anonymous and totally worth a try. It also supports Segwit and bech32 Addresses, with some terms attached. For e.g. only witness version bech32 addresses are supported. Similarly, only the addresses starting with the number “3” are supported. Yomix : Uses stealth pools to anonymize transactions Mixero : Excellent customer support Bitcoin Mixer : It offers flexible transaction fees and a low minimum transaction limit Coin Mixer : Fast payouts Coinmize : Zero-log policy 1. Yomix - Uses stealth pools to anonymize transactions Yomix will be reliable and easy to use. It has been around for several years and is probably considered one of the most popular mixers on the darknet. Yomix charges a commission randomly in 1-3%, and also provides sending coins to 10 different addresses for increased anonymity. Due to randomization, withdrawal amounts turn out to be unpredictable, which again increases anonymity. BitBlender requires you to create an account to use the full suite of tools, but if you don’t want to register, this mixer offers a “quick blend” mode. When using the Quick Mix feature, you will be sent a code that identifies each individual operation to ensure that you do not receive any previously sent coins back. BitBlender provides two additional features. Auto-Withdrawal and Quick-Withdraw. Auto-Withdrawal will dramatically decrease your runtime if you have to constantly clean your coins. Quick Mix comes in handy for the casual user who doesn’t want to register.Another solid Bitcoin Tumbler option, Yomix requires a minimum deposit of 0.01 BTC to be made but makes up for this with a lower transaction fee of 2% coupled with a 0.0004 BTC network fee. Support for multiple addresses and customer options is provided with users required to provide confirmation for only 1 address. While there is no referral program available, Yomix does offer users with a letter of guarantee for their peace of mind.What marks Yomix out from the crowd is the fact that this crypto mixer is able to process transactions for Bitcoin and Litecoin. There is a minimum deposit requirement for both Bitcoin and Litecoin. The site is able to support a maximum of 5 multiple addresses with confirmation required for all addresses. No site registration is required and there is a referral program in place. Additionally, Yomix can provide clients with a letter of guarantee.This particular Yomix supports Bitcoin cryptocurrency and does not bear any logs policy.

This dark service uses new technology, it doesn’t just clean up your coins, you get brand new coins that have never been on the dark web. The cleaning process can take no more than 4 hours. To carry out cleaning on Helix in the basic version of Grams, you need to register, in the versions of Helix Light and Helix Market this is not necessary. If you still decide to use the Grams version, you will have to pay an entrance fee of 0.01 BTC. Helix has an additional feature (Auto-Helix) that allows you to specify which addresses your coins will be mixed with when they are credited to your account. Helix also enforces a “no log” policy, all logs are deleted automatically after 7 days or by the user immediately after completion of the output. Helix has a third party server not connected to Grams. A number of Bitcoin client programs that he uses are located on a completely separate server from Helix and Grams. Even if Grams is attacked or compromised, Helix will not be affected.It is a simple service with a high level of anonymity. The Mixero mixing process is very simple and only takes a couple of minutes. You need to select one of the three supported cryptocurrencies (Bitcoin, Litecoin, Bitcoin Cash), enter the withdrawal address, set the transaction delay for any time up to 72 hours, send the coins to the specified address and wait for their delivery to the destination. This site is unlike the other three mixing pools. You can mix user’s coins: with incoming coins of other customers, private reserves of the service and investor coins. The service does not require registration. The mixing commission is not large and is taken from the mining commission, which is very convenient. The referral program at SmartMixer is one of the most profitable, during the first mixing operation you receive a smart code that is required to receive a discount on the commission, this discount can reach – 70%. After each transaction, the user receives a letter of guarantee. All data about it is deleted after a day, while maintaining the complete anonymity of the client. Pros: Excellent customer support No-logs polici 3. Bitcoin Mixer - It offers flexible transaction fees and a low minimum transaction limitBitcoin Mixer is a Bitcoin mixing service that provides privacy by using the ‘Bitcoin Mixer 2.0’ algorithm to shuffle bitcoins. Unlike other similar tumbling services that mix your coins with the coins of other users, this platform mixes your crypto with the crypto bought by them directly from the cryptocurrency stock exchanges. Bitcoin Mixer verifies the newly purchased coins with a scoring system with the help of innovative algorithms and outfoxes such technologies as blockchain volume analysis, cluster analysis, taint analysis, etc. It means that you will receive your BTC back split into random parts, and even at the different addresses if needed. Consequently, your privacy is protected as there is no connection to you. And it takes up to 6 hours to complete your request. Another privacy feature of this mixer service is that it does not require registration and it does not store logs. All the transactions are digitally signed with letters of guarantee that you can check on the website at any moment. They also provide 24/7 technical support. MixTum.io will charge you a 5% Fee from your transaction as well as a network fee of 0.00015 BTC. The platform provides two versions – for Clearnet and Tor browsers.Bitcoin Mixer is a Bitcoin cleaner, tumbler, shifter, mixer and a lot more. It has a completely different working principal than most other mixers on this list. So, it has two different reserves of coins, one for Bitcoin and the other for Monero. It cleans coins by converting them to the other Cryptocurrency. So, you can either clean your Bitcoins and receive Monero in return, or vice-versa. The interface is pretty straight-forward. You simply choose your input and output coins, and enter your output address. For now, only 1 output address is supported which we believe simplifies things. The fee is fixed which further makes it easier to use. You either pay 0.0002 BTC when converting BTC to XMR, or 0.03442 XMR when converting XMR to BTC. It also provides a secret key which can be used to check transaction status, or get in touch with support. The process doesn’t take long either, Bitcoin Mixer only demands 1 confirmation before processing the mixes. Bitcoin amounts as low as 0003BTC and XMR as low as 0.05 can be mixed. It doesn’t require any registrations so obviously there’s no KYC. The company seems to hate the govt. and has a strict no-log policy as well.It is a simple service with a high level of anonymity.

‘Dyson spheres’ were theorized as a way to detect alien life. Scientists say they’ve found potential evidence
кракен даркнет
What would be the ultimate solution to the energy problems of an advanced civilization? Renowned British American physicist Freeman Dyson theorized it would be a shell made up of mirrors or solar panels that completely surrounds a star — harnessing all the energy it produces.
“One should expect that, within a few thousand years of its entering the stage of industrial development, any intelligent species should be found occupying an artificial biosphere which completely surrounds its parent star,” wrote Dyson in a 1960 paper in which he first explained the concept
https://kra31s.cc
кракен онион
If it sounds like science fiction, that’s because it is: Dyson took the idea from Olaf Stapledon’s 1937 novel “Star Maker,” and he was always open about that. The late scientist was a professor emeritus at the Institute of Advanced Study in Princeton, New Jersey.
Still, coming from a thinker who some in the scientific community say might have been worthy of a Nobel Prize early in his career, the concept took hold and the hypothetical megastructures became known as Dyson spheres, even though the physicist later clarified that they would actually consist of “a loose collection or swarm of objects traveling on independent orbits around the star.”
In his paper, Dyson also noted that Dyson spheres would give off waste heat detectable as infrared radiation, and suggested that looking for that byproduct would be a viable method for searching for extraterrestrial life. However, he added that infrared radiation by itself would not necessarily mean extraterrestrial intelligence, and that one of the strongest reasons for searching for such sources was that new types of natural astronomical objects might be discovered.
“Scientists (at the time) were largely receptive, not to the likelihood that alien civilisations would be found to exist, but that a search for waste heat would be a good place to look,” said George Dyson, a technology writer and author and the second of Dyson’s six children, via email. “Science fiction, from ‘Footfall’ to ‘Star Trek,’ took the idea and ran with it, while social critics adopted the Dyson sphere as a vehicle for questioning the wisdom of unlimited technological growth.”
