New research puts age of universe at 26.7 billion years, nearly twice as old as previously believed::Our universe could be twice as old as current estimates, according to a new study that challenges the dominant cosmological model and sheds new light on the so-called “impossible early galaxy problem.”
Narrowing it based on what we can measure doesn’t mean it’s correct.
The deeper we have stared into the universe the more our base understandings have challenged.
Hence the “unless there’s something seriously wrong with the previous research” part. That is always a possibility, of course, but it’s much less likely that is the case then that this single study is the thing that is wrong.
