The Hubble Space Telescope, launched in 1990, has captured light from galaxies more than 13 billion light-years away.

Why it matters

The idea in context

The Hubble Space Telescope, launched in 1990, sees the universe without atmosphere blurring the view. A light-year is about 9.5 trillion kilometres (5.9 trillion miles), so light from the most distant galaxies is also ancient: looking far away means looking billions of years into the past.

1990'da fırlatılan Hubble Uzay Teleskobu, 13 milyar ışık yılını aşan uzaklıktaki galaksilerden gelen ışığı kaydetti.
NASA

Hubble, Dünya atmosferinin bulanıklaştırıcı etkisinin üzerinde çalıştığı için evreni yer teleskoplarından çok daha keskin görüntüledi. Bir ışık yılı yaklaşık 9,5 trilyon kilometredir (5,9 trilyon mil); bu yüzden en uzak galaksilerden gelen ışık yalnızca mesafeyi değil zamanı da anlatır: uzağa bakmak, milyarlarca yıl geçmişe bakmaktır.

Q0411

The Apollo Guidance Computer flew astronauts to the Moon with about 4 KB of working memory — your phone has roughly a million times more.

The AGC had about 4 KB of RAM, 72 KB of fixed 'rope core' memory, and ran at roughly 1 MHz — less computing power than a musical greeting card. Yet in 1969 it steered Apollo 11 across 380,000 km, ran the landing radar, and even recovered gracefully from overload alarms minutes before touchdown. The story is not about weak hardware; it is about what disciplined engineering, compact code and ruthless prioritising can do under impossible constraints.

Q0412
WonderTechnology

Quantum behaviour can appear in engineered electrical circuits large enough to be physical devices, not only in isolated particles.

Superconducting circuits can behave as quantum systems when cooled and isolated carefully enough. This is one route toward quantum computers, where fragile effects must be protected from everyday noise. The so-what is modern: quantum physics is not only a strange theory of tiny things; it is becoming hardware people can build.
