Recent Big Think / Ask Ethan items center on foundational astronomy questions: how empty is deep space, why distant galaxies appear to move so fast, and what defines a planet — including renewed arguments to reclassify Pluto based on geophysical traits rather than orbital clearing. Related pieces touch on cosmic distance records, Neptune and the outer Solar System, and how supermassive black holes launch powerful jets, while a podcast episode examines Neptune’s realm. Although many entries lack full text in the provided excerpts, together they reflect a trend toward revisiting core cosmology and planetary-taxonomy topics—clarifying scales, motions, and classification in modern astronomy.
Tech professionals rely on accurate science communication to inform data visualizations, simulations, and public-facing tools; gaps in source content affect trust and reuse. Understanding how astronomy topics are presented helps engineers and product teams decide when to source primary research versus summary explainers.

Big Think published a Chinese-titled entry, “问伊森：宇宙深处究竟有多空旷？” (“Ask Ethan: How empty is deep space?”), apparently part of its “Starts With A Bang” astrophysics column. However, the provided text contains only Big Think site navigation and promotional listings (membership options, topic menus, and recent video headlines) and does not include the article’s body, author, publication date, or any scientific claims or figures. Based on the title alone, the piece likely addresses how matter is distributed in the universe and what “emptiness” means across interplanetary, interstellar, and intergalactic scales, but the available excerpt does not provide verifiable details. More content is needed to summarize the specific arguments, data, or conclusions.
Big Think published information about episode 129 of the “Starts With A Bang” podcast, titled “Neptune and the outer Solar System” (《Starts With A Bang》播客第129期——海王星与太阳系外层). The provided page text is largely site navigation and category listings rather than the episode’s full description, transcript, guests, or release date. Based on the title, the episode focuses on Neptune and topics related to the Solar System’s outer regions, likely within Big Think’s “Starts With A Bang” astronomy/astrophysics column and podcast lineup. No additional details—such as the host, specific scientific questions covered, runtime, or links to audio platforms—are included in the supplied content, limiting what can be confirmed beyond the episode identification and general subject area.
The provided text appears to be a Big Think page header and navigation menu rather than the full article titled “故事的力量：发掘历史中被遗忘的声音——从庞贝古城开始” (“The power of stories: uncovering forgotten voices in history—starting with Pompeii”). It lists site sections (Philosophy, Science & Tech, Mind & Behavior, Business, History & Society), membership options, and links to recent videos and columns, but contains no article body, author, publication date, or substantive discussion of Pompeii or historical storytelling. As a result, only limited information can be summarized: the page is associated with Big Think and seems categorized under History & Society, but the specific claims, sources, and significance of the Pompeii-focused piece are not available in the excerpt.
Big Think published an article titled “宇宙距离纪录简史” (“A brief history of cosmic distance records”). However, the provided text contains only Big Think site navigation and category listings (e.g., Science & Tech, Astronomy, Aerospace) rather than the article’s body. As a result, specific details about the piece—such as the author, publication date, the distance milestones covered, the telescopes or missions involved, and any numerical records—are not available from the supplied content. Based on the title alone, the article likely discusses how astronomers have progressively measured and extended known distance records in the universe, a topic relevant to cosmology and observational astronomy. More information is needed to summarize the actual claims, examples, and data presented in the article.
Big Think published a Chinese-language “Ask Ethan” astronomy explainer titled “Why can distant galaxies move so fast?” The provided text contains mostly site navigation and membership links, with no substantive article body, author details, publication date, or scientific explanation included. Based on the title, the piece likely addresses why very distant galaxies can appear to recede at extremely high speeds—an effect commonly discussed in cosmology in terms of the universe’s expansion and how recession velocity relates to distance. However, because the actual content is not present in the supplied excerpt, specific claims, numbers, references, or conclusions from the article cannot be verified or summarized. More article text is needed for an accurate, detailed summary.
The provided text appears to be a scraped navigation page from Big Think rather than the full article “放慢脚步这一激进之举” (“Slowing down is a radical act”). It lists site sections (Philosophy, Science & Tech, Mind & Behavior, Business, History & Society), membership options, and a carousel of recent videos and columns, but contains no article body, author, publication date, or substantive claims tied to the title. As a result, it is not possible to summarize what argument or news the piece makes, identify key players, or explain why it matters based on the available content. The only clear information is that the content is associated with Big Think’s website and its membership-driven media offerings.
The provided text appears to be a Big Think page shell rather than the full article “超大质量黑洞会喷射出最强大的宇宙喷流” (“Supermassive black holes can launch the most powerful cosmic jets”). It includes navigation elements and topic menus but no substantive body text, author, publication date, or scientific details. Based on the title alone, the article likely discusses how supermassive black holes generate extremely energetic relativistic jets and what conditions (such as black hole mass, spin, accretion rate, and magnetic fields) influence jet power, a key issue in understanding galaxy evolution and feedback. However, no numbers, study references, or specific findings are available in the supplied content, limiting what can be summarized accurately.
The Big Think article argues there is a scientific case for reclassifying Pluto as a planet, revisiting the International Astronomical Union’s 2006 decision that demoted it to “dwarf planet.” It focuses on how the IAU’s definition—especially the requirement that a planet must “clear its orbit”—can be interpreted as ambiguous or overly dependent on a body’s location and neighborhood rather than its intrinsic geophysical properties. The piece contrasts Pluto’s complex geology and planetary characteristics with the taxonomy used for other Solar System bodies, suggesting alternative definitions could restore Pluto’s planetary status. The debate matters because classification standards shape how scientists communicate, how missions are framed, and how the public understands Solar System formation. The provided text includes navigation elements but limited article detail.
