I thought I read somewhere that the Earth is expanding at the mid-oceanic ridges. That's where the youngest crust is.
The usual argument is 'how does the Earth grow?' Maybe the Earth receives energy and converts it to mass. Just because we don't understand the process...
Dinosaurs where too big for present gravity. Smaller Earth, less gravity. Everything grows big.
Makes sense. Everything grows.
Quoting: Anonymous Coward 26363198 Earth is just expanding from the mass it had at the beginning, a bigger planet means less density not necessarily more mass ! The dinosaurs were so big because there was a much higher concentration of oxygen in the atmosphere back then ! I don't think this is correct. The dinosaurs were too big if gravity was the same. The Earth expanded by gaining more mass and therefore increasing gravity. Hell, somebody calculated that something like 10,000 tons of space dust and rocks hits the atmosphere every day. Multiply that by a few billion years.
