Scientists from Nanjing University and Chinese and American collaborators used the Very Large Array Radio Telescope in New Mexico to observe radio radiation from the center of the M32 galaxy. This is corroborated by the X-ray radiation previously observed at the center of M32 and the high-speed star motion at that location. The researchers said, "We think this radio source is most likely to be the black hole at the center of M32." At the same time, this discovery may be the largest black hole known to mankind, with a mass of approximately 12 billion times the mass of the sun.
But recently, American physicist Laura Mersin-Houghton published an article claiming that black holes do not exist. Although many people have said this before, for example, the British physicist Hawking also said that "black holes do not exist" (but he meant it literally). But Mersin Horton's research is extremely special and seems impeccable. If she is correct, then both physics and astronomy have to be rewritten.
Have you heard? There is a "shy" black hole in the neighbouring galaxy M32
In a narrow sense, it is not so important to discuss whether there are black holes. The key is how much black holes are related to humans. (At present, it is impossible to affect humans, because even the closest Sagittarius black hole claimed to be discovered is 1600 light-years away from Earth. I am afraid that our generation does not need to worry about what will happen to astronauts if they approach the black hole?)--Same It is not important whether smart home products are cool or not. The key is how much convenience and benefits it can bring to each of us.
Looking at the current smart home market, it mainly revolves around personal safety (video surveillance, security doorbells, smart door locks, etc.), health and fitness (air purification, fitness bracelets), and environmental energy-saving (smart sockets, smart switches, light control, etc.) Control windows, smart home appliances, etc.), games and entertainment (intelligent audio and video, TV/game box, router) are launched separately. In fact, in addition to the helpless demand caused by PM2.5 in some areas (last year's Double Eleven, sales of air purifiers were the top home appliances), and the low-cost threshold of fitness bracelets and smart sockets, which attracted high-volume experience, OFweek Industry Research The center's smart home research team noticed that the remaining products did not stimulate particularly large demand. Moreover, except for the seemingly awesome control of lights and windows and smart switches, which are new products in recent years, all other products have more than 20 years or more of industry accumulation. In other words, most of the big platter of smart home is still old medicine in new bottles.
It is said that the technical foundation of smart home has been established for a long time. The key is how to integrate and innovate into smarter products to attract users to pay for new needs. Liu Shuhui, a senior analyst at OFweek Industry Research Center, believes that, indeed, the ultimate goal of smart home is that every single product has a certain degree of artificial intelligence, understands empathy, and can even communicate and work together like an invisible servant. We take care of all our daily lives with care, and always create a safe and comfortable environment. Hold on, wake up! In real life, how many families have a babysitter or private housekeeper? According to the ultimate goal of smart homes and the current economic development speed of the society, it will take decades to popularize smart homes that have a private housekeeper in every household?
Back to the topic of convenience and benefits. In addition to satisfying individual needs and taking into account herding factors, mass consumption is to calculate the input-output ratio. Pursuing a scene that is as cool as a sci-fi blockbuster, until someone is willing to pay the bill to become GDP. During the period of function realization, how much demand is not a pseudo-demand that is rarely imagined, but a financial report that can withstand the test of the market? (Of course, financial predators who are keen to invest in the future are often not afraid of burning money, and often do not read financial reports. Haha, then it is not discussed in this article)
In fact, smart home is still a traditional industry. Internet+ is just an additional display competition and sales communication channel, not so impatient. Returning to the original intention of making products, if each product can return to the original intention of practical, convenient, easy-to-use and reliable design, make each product smarter, and then smarter, plus openness and interconnection, will not be the joint creation of the home Is it intelligent?
