even if we look back in the time span of each ages and consider that all four yugas make one chaturyuga and 71 of chaturyuga make one manayantara and their are 4 manvantara make a kalpa. there are 14 kalpas altogether that make a year in brahmaloka. there are rigorous mathematics for these, but i told you in short.
if we combine this thought to the concept of planetary motion that a planet whose contour of orbit is larger than that 0f smaller ones has a longer year too. this concept can be expanded for different galaxies in the cosmos too.
after many assumptions we may end up proving the existence of mythological lokas (although it would never be like what described in the scriptures) in a different format. đ
