" It challenges conventional understanding of dark matter and how dark matter should behave , " said arif babul of the university of victoria .
“它挑战到人类对暗物质的传统理解以及暗物质是如何表现的解释”，维多利亚大学的阿里夫-巴布尔说道。
Babul said the dark matter clump has recently been detected by other ground-based telescopes , leaving him confident that it does , in fact , exist .
巴布尔说，暗物质团最近已被其它的地面望远镜所侦测到，这使他相信，它确确实实是存在的。
That prompted mr. babul and his colleagues at the university of california davis and san francisco state university to turn to nasa 's hubble space telescope , expecting - hoping , in fact - to learn their initial discovery was incorrect .
If the current theories are wrong , mr. babul said it could change everything from how scientists explain the formation of galaxies - a process that depends entirely on the existence of dark matter - to where gamma rays come from .
