Hydrogen atoms, in the universe at a density of approximately 2-fold higher than dogma? !

Research group Fukui professor of Nagoya University Graduate School of (radio astronomy) and colleagues have found that hydrogen atom, which accounts for 90% of the constituents of the universe, in the universe at a density of approximately 2-fold higher than dogma. Of a treasure trove for understanding the process such as the formation of stars. Fukui professor explained, "assuming the research and materials. Universe dogmas are also listed in textbooks covered varies greatly" he said.

The density of hydrogen is calculated using a relational expression between radio wave strength of hydrogen. In the past, "0.8 pieces per cubic centimeter per average" was established theory based on the formula of the premise that hydrogen is present in the state of absolute temperature 125 degrees or more. In practice, however, is confirmed by this analysis that the more hydrogen is present in 20-50 degrees absolute temperature. It was found that hydrogen is present at a density of "two or more per cubic centimeter per round" Calculating the formula research group led anew.

The research group, analyzes the latest data radio telescope that has a big name installed in Chile, such as "2 do Nante". I was the observation target (dust) dust scattered (clouds of hydrogen gas) molecular cloud at a distance of 500 light-years from the solar system. Examine the correlation of temperature, density, signal strength of hydrogen, to confirm the new official. In this formula, the fitting results of measuring the signal strength in the whole universe was indexing the density of hydrogen in the whole universe.

  Credibility it seems expensive Because it seems official that were derived from the experimental data. Space derived by assumption changes large it might be varies considerable.


名古屋大大学院の福井教授（電波天文学）らの研究グループは、宇宙の構成物質の９割を占める水素原子が、定説よりも約２倍の密度で宇宙に存在することを突き止めた。星の形成過程などを考える上で貴重な発見という。福井教授は「教科書にも載っている定説が覆った。宇宙の物質などを研究する前提が大きく変わる」と説明した。
　水素の密度は、水素の電波強度との関係式を用いて算出する。従来は、水素が絶対温度１２５度以上の状態で存在する前提の式に基づき「１立方センチ当たり平均０．８個」が定説だった。しかし実際は、多くの水素が絶対温度２０〜５０度で存在することを今回の解析で確認。研究グループが新たに導いた公式で計算すると「１立方センチ当たり平均２個以上」の密度で水素が存在することが分かった。
　研究グループは、名大が南米チリに設置する電波望遠鏡「なんてん２」などの最新データを解析。太陽系から５００光年の距離にある分子雲（水素ガスの雲）に散らばるダスト（ちり）を観測対象とした。水素の温度・密度・電波強度の相関関係を調べて、新たな公式を確認。この公式に、宇宙全体で電波強度を計測した結果をあてはめ、宇宙全体の水素の密度を割り出した。
 　実験データーから導き出した公式のようですから信憑性が高そうですね。前提が大きく変わることによって導き出される宇宙が相当変わってくるのかもしれませんね。
