Materia neagră
Materia neagră este partea invizibilă a Universului, ea reprezentând mai bine de un sfert din masa şi energia Universului, susţin oamenii de ştiinţă, potrivit Wired.com.
Totodată, materia neagră nu interacţionează cu materia "comună" din Univers, decât prin intermediul gravitaţiei.
Totodată, materia neagră are o concentraţie mai mare în zonele în care "găzduieşte" sute de mii de galaxi (zone cluster), moment în care devine un fel de "lupă" pentru cele mai adânci părţi ale Universului.
Astfel, oamenii de ştiinţă, folosind o astfel de "lupă cosmică", au reuşit să creeze o hartă detaliată, 3D, a unei porţiuni de Univers.
