Sveiki,
Kiek zinau, visuotinai priimta visatos amziu laikyti apie 13 mlrd metu, kaip 
tuomet galima paaiskinti objektu (kvazaru) egzistavima uz daugiau kaip 20 
mlrd sviesmeciu? Iseina, kad sviesa nuo ju iki musu keliauja ilgiau negu 
egzistuoja visata? Ar cia taip atsitiko del kokiu nors erdvelaikio 
iskraipymu ankstyvame visatos raidos etape?

"More than 200,000 quasars are known, most from the Sloan Digital Sky 
Survey. All observed quasar spectra have redshifts between 0.06 and 6.5. 
Applying Hubble's law to these redshifts, it can be shown that they are 
between 780 million and 28 billion light-years away (in terms of comoving 
distance). Because of the great distances to the furthest quasars and the 
finite velocity of light, we see them and their surrounding space as they 
existed in the very early universe."
