Brand Modern research suggest that the universe is actually a lot more crowded than antecedently retrieve . There are up 2 trillion galaxies in the seeable universe , more than 10 times previously count on .
This inquiry was conduct by prof Christopher Conselice of the University of Nottingham , and his partner at the Leiden Observatory and the University of Edinburgh , and is the culmination of 15 twelvemonth workplace .
The team looked at the density of coltsfoot at unlike epoch and discovered that there seemed to be at least 10 meter more galaxies in any given book in the first few billion age than we see today . Most of those galaxies were small , so they are currently difficult to observe .
“ This is very surprising as we fuck that , over the 13.7 billion old age of cosmic evolution since the Big Bang , galaxies have been growing through wizard formation and unification with other galaxies , ” Conselice allege in astatement .
“ Finding more coltsfoot in the yesteryear inculpate that pregnant phylogenesis must have occurred to reduce their number through extensive merging of system . ”
It was antecedently thought that the evident world had 100 billion galaxies ; this estimation was obtained in the nineties based on theHubble Deep Field images . But the better models and pawn that have been developed over the last 20 years point towards a fussy universe .
accord to this latest research , which is availableonlineand accepted for publishing in the Astrophysical Journal , there could be between one and two trillion galaxies out there , and we have only seen a humble fraction of them .
“ We are miss the immense majority of galaxies because they are very swooning and far off . The number of galaxies in the universe is a key doubt in uranology , and it boggles the mind that over 90 percentage of the galaxies in the macrocosm have yet to be studied , ” added Conselice .
“ Who knows what interesting property we will regain when we hit the books these extragalactic nebula with the next multiplication of telescopes ? ”
This newfangled estimation has important consequences on how galaxies have evolve throughout the old age of the universe . The rate at with galax have fuse must have been much high during the first few billion years of the cosmos .
Astronomy is the skill of recede purview . When our pawn better we can then look deeper and further away into the cosmos , and every advancement has demonstrate that the universe is a lot more complex , bigger , and fuller than we antecedently thought .
