外星人的问候？加拿大发现了15亿光年的重复无线电波_我的网站

A |     Birkenstock took a big step forward on Wall Street this week, taking the nearly 250-year-old German shoe and sandal maker public.The footwear, often seen as a counter culture shoe for hippies, and in more recent years influencers, has become must-have footwear for many people, but Birkenstock's Initial Public Offering, or IPO, which was originally priced at $46 per share, didn't attract the dress shoe-wearing stock brokers on Wednesday.Shares opened at $41, near the lower end of its expected range of $44 to $49 set a week prior, as Birkenstock CEO Oliver Reichert rang the opening bell in a room surrounded by traders sporting the opened-toed footwear and others waving the sandals in the air.Birkenstock Holding Ltd. sold nearly 10.8 million shares in the offering, which raised about $495 million on the day. Its shareholders sold an additional 21.5 million shares, according to the Associated Press."Through the strong reputation and universal appeal of our brand -- enabling extensive word-of-mouth exposure and outsized earned media value -- we have efficiently built a growing global fanbase of millions of consumers that uniquely transcends geography, gender, age and income," Birkenstock said in a recent regulatory filing with the Securities and Exchange Commission, according to the AP.What started out in 1774 as a somewhat frumpy, but functional arch support sandal has transformed into a cult fashion item and billion dollar business, bolstered with support from the recent blockbuster hit "Barbie" when Margot Robbie's character is forced to choose between high heels or the strappy suede footwear.In tandem with the opening on Wall Street, Birkenstock hosted three consumer activations in public parks throughout Manhattan and Brooklyn.To highlight New York as "the city that never stops walking," the brand created what it dubbed "Birkenfields" for a public sensory experience that explored the brand's nearly 250-year heritage and expertise in foot health.The global brand is deeply rooted in foot health maintenance as well as a family tradition of shoemaking: Its inventor sought to provide function, quality and tradition as Birkenstock's core values.Over 95% of Birkenstock products are assembled in Germany with more than 90% of their materials and components sourced from Europe, ensuring the brand meets "the highest environmental and social standards in the industry by operating state-of-the-art scientific laboratories for materials testing," according to a company press release.。加拿大天文望远镜在两个月内捕捉到13次快速的无线风暴，其中包括15亿光年外异常重复的无线电波。科学家们说，他们不能排除电波来自外星航天器的可能性。这项研究现已发表在《自然》杂志上。报道称，13次快速无线风暴中的一次非常罕见，它来自15亿光年之外，是第二次发现重复性无线电波。以前，研究人员用不同的望远镜捕捉相同的波。研究人员说，他们通过加拿大氢强度测绘实验射电望远镜发现了电波，该望远镜由4个100米长的半圆柱形天线组成，去年发射，在发射后不久检测到13次射电爆发，包括重复波。有许多理论可以解释这些宇宙波的起源。例如，这些波可能来自具有强磁场的中子星，或者两个中子星可能合并在一起。除了这些理论之外，一些观察家认为这些波实际上来自某种外星航天器。
