Angiosperms were beginning to take over from gymnosperms. Now, as compared to gymnosperms. Angiosperms are easier to digest and require a much smaller gut size. Thus, size of herbivorous dinosaurs would have reduced. And that would have gradually led to reduction in size of carnivorous dinosaurs as well. Scientists also think that dinosaurs might have become more intelligent. Because dinosaurs like Troodon. Who were considered smart. And had a large brain compared to their body size were beginning to evolve. But, what about us, that is, humans? Humans were able to evolve. Because the impact of the asteroid killed the dinosaurs. Triggered drastic changes in climatic conditions. Which led to mammalian evolution and eventually human evolution. Thus, had the asteroid never crashed, we probably wouldn't have existed. What If a Massive Solar Flare hits earth? I will use my AumSum shield and protect the Earth. Oh AumSum. Solar flares are sudden and massive eruptions of electromagnetic radiations. From the sun's surface. A massive solar flare which occurred in 1859 had minimal impact. But it would have massive disruptions today. Mainly because of our over reliance on technology. The earth's surface would be safe but our atmosphere. Would bear the entire brunt of radiation. That is, radio waves, x-rays, gamma rays, etc. Firstly, there would be a major disruption of power grids. Possible leaving cities or even countries without any electricity. Secondly, our good old radio communication would be down and out. Thirdly and most importantly, GPS & Satellite Communications would be hit. This would cause major problems for transportation and communication. Lastly, because of massive Auroras our atmosphere would look like a magnificent painting. What if all the Bees die? No ways. I will sell all my burgers and create a safe house for them. That's so cute Aumsum. There are more than 16,000 species of bees. Bees generally collect pollen and nectar from flowers for their survival. In this process they help pollinate majority of the fruits. And vegetable crops which are consumed in the world today. Some studies reveal that more than 90% production of cherries, blueberries. And almonds is a direct result of the pollination efforts of bees. Also, certain bees have evolved as per the size and structure of specific flowers. Hence if there are no bees, these plants would definitely go extinct. This will also have a catastrophic effect on the food chain. As the animals eating those plants will slowly but surely perish. Finally, because of the absence of natural sweetener like honey. Many people may switch over to an unhealthy artificial sweetener like sugar. What if the earth was Cube-Shaped? Holy Moly. Will my cute chubby round face also turn into a cube? Oh AumSum. Earth is spherical in shape because of Gravity. Earth's gravity pulls everything equally towards its center. And thus gives it a spherical shape. Now, if the earth was Cube-shaped. Firstly, it would look weird, right. Secondly, just like gravity. Our weight would be different at different places on earth. This is because the 8 corners of the cube. Would be much further away from the cube's center. As compared to the rest of the cube. But this would be good news for people who are over-weight and lazy. Now they can just go to the corners and voilaaa, their weight gets reduced. Thirdly, due to low gravitational force. The cube corners would have very less atmospheric cover & almost no water. Thus rendering them inhospitable.
