To most people who aren’t physicists, Albert Einstein’s Special Theory of Relativity is probably just a vague concept that somehow explains why Matthew McConaughey doesn’t age in Interstellar. But to ...

Planets that orbit white dwarf stars should be too hot to host alien life, theories suggest. But a new study accounting for Einstein's general relativity may rewrite that rule. When you purchase ...

理論物理学者のアルベルト・アインシュタインが打ち立てた相対性理論は現代物理学の基本となる重要な理論であるものの、ブラックホールなど複雑な事象に関係するものというイメージもあり、日常生活に相対性理論が関係しているとは考えにくいかも ...

This is the first time that disk-jet co-precession has been clearly observed in a black hole system, which is truly exciting, ...

Since Einstein, physicists have found that certain entities can reach superluminal (that means "faster-than-light") speeds and still follow the cosmic rules laid down by special relativity.

Why the universe is expanding faster and faster remains one of the biggest open questions in physics. Current theories cannot ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...
