Sort hul

Et sort hul er en samling af masse s� stor/t�t, s� end ikke elektromagnetiske b�lger (f.eks. radiob�lger og lys) kan udsendes fra dens "overflade".

Sorte huller deles i to grupper:

1. Sorte huller med masser som stjerners.
2. Sorte huller som har masser som milliarder af stjerner kaldes massive sorte huller (MBH). De formodes at v�re i centrum af aktive galakser og almindelige galakser.

Universet udg�res af elementarpartikler og vakuum. Partiklerne er fordelt uj�vnt og partiklerne og partikelklynger ben�vnes forskelligt afh�ngig af t�thed og m�ngde; klyngerne sp�nder lige fra subatomare partikler til sorte huller.

En m�ngde af partikelklynger i vakuum er:

Gas | Atmosf�re | Solvind | Kosmisk str�ling | Asteroideb�lte | Stjernehob, Stjernet�ge | Solsystem | Galaksehob
