宇宙創生の物理法則はなにか?- 理論・観測・実験の融合によるスケールを超えた挑戦

What is the physical mechanism of the origin of the Universe? - challenges over transcending scales through the integration of theory, observations, and experiments

宇宙は138億歳の現在膨張し続けているが、宇宙が生まれた直後は10^-26cmよりも小さく、宇宙全体が量子の世界だったと考えられている。自然科学の究極のテーマ「宇宙創生」に挑むには,観測天文学だけでなく,極小の宇宙で主役であった素粒子,微弱な信号を最高感度で捉える量子計測技術,ビッグデータから最大限情報を引き出すAI,新たな物理法則を構築する理論の研究者の集結が必要である。日本が世界的に有する強みと今までの投資を最大限活かし,テーブルトップ実験も含めて30桁を超える実験・観測のスケールと60桁に迫る物理のスケールの統一的な理解を目指す。必然的に既存の分野を大きく超え,宇宙創生の物理法則の解明を目指す新たな学術分野を創出する。この学術変革領域のキックオフミーティングを開催する。(一般講演の締め切りは6/22といたします)

本研究会は英語で実施します。

The universe continues to expand 13.8 billion years after its birth. In its earliest moments, it is thought to have been smaller than 10−26 cm, with the entire universe existing in the quantum realm. Tackling the ultimate question in natural science -- the origin of the universe -- requires not only observational astronomy, but also the collective efforts of researchers in particle physics, which studies the fundamental constituents that governed the microscopic early universe; quantum measurement technologies capable of detecting extremely weak signals with ultimate sensitivity; AI methods that extract maximal information from massive datasets; and theoretical physics that seeks to formulate new laws of nature.

By fully leveraging Japan’s internationally recognized strengths and past investments in these areas, we aim to achieve a unified understanding spanning more than 30 orders of magnitude in experimental and observational scales, from tabletop experiments through observational cosmology, and nearly 60 orders of magnitude in physical scales. This endeavor will necessarily extend far beyond existing disciplinary boundaries and create a new academic field dedicated to uncovering the physical laws governing the origin of the universe.

This kickoff meeting marks the launch of this Transformative Research Area (A).  The primary language of the workshop will be English.
