was king, with dark matter at about 83% and normal matter at around 17% of the Universe. And this was true from when the Universe was about 1% of its current size (when it was only about 10 million years old) until dark energy took over.

But when the Universe was even smaller? Radiation — in the form of photons and (to a slightly lesser extent) neutrinos — was not only important, but at small enough scales, dominated the Universe. Radiation dominates all the way back until inflation happened, and our Universe, as we know it, firstbegan.

The cosmic microwave background came at an important transitional time in the Universe, when it was about 0.092% of its current size. At that time — when the Universe was only 380,000 yearsor 3, his mother insisted that she'd never buy him any toy guns (LEGOs, pop
guns, or anything). When he'd visit us, he always somehow dug out the old pop
gun toys we had buried away. A year later, I visited her and she'd entirely
caved. I asked her about it, and she said she gave up when she realized he was
just using sticks or anything else he could think of simulate one while he
continued playing cops and robbers and all the "violent" games little kids
play.

The price LEGO had to pay for going down the lucrative movie franchise /
merchandise road... btw, is the main audience still kids?

tl;dr - researchers are a scared of increasing trend of 'violent' Lego toys
mostly because of movie sets
