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.”

    Isn’t dark matter just matter we can’t percieve? Rogue asteriods and the like? I admit its been a minute since I studied this stuff, but dark matter isn’t very special.

      It’s been a minute, but the universe is expanding and the speed of the expansion depends on the total gravity. When we calculate the amount of mass it would take to make that much gravity, it’s way more than what we actually see out in the universe. It’s really a cheeky way of saying our current model makes tons of good predictions so we trust that something is out there, but in reality we don’t know its nature and can’t detect or measure it directly.
