The year is 2117. Humanity has spent the last 100 years stockpiling nuclear warheads. And not just a few – 600 billion of the largest, biggest, deadliest warheads they can build. Sort of like the Russian Tsar Bomba (the biggest nuclear bomb ever detonated) but, well, times 600 billion. Why? Because we’ve decided to blow up the Moon, and to do so would require the equivalent of 30 trillion megatons of TNT. When we say blow up, we don’t just mean slightly-blow-up. See, if you don’t completely obliterate the Moon, the remaining fragments will likely coalesce back together into a Moon-sized object. Sure, it won’t look as pretty or as spherical as our modern Moon, but it will be pretty similar in its gravitational effect on Earth. No, what we (or, more specifically, our future selves) want to do is completely get rid of the Moon. So, with their multiple rockets ready and waiting to attack the Moon from all sides, they launch them towards our natural satellite and blow...

              What happen if all 🐝 die Where would we be without bees? As far as important species go, they are top of the list. They are critical pollinators: they pollinate 70 of the around 100 crop species that feed 90% of the world. Honey bees are responsible for $30 billion a year in crops. That’s only the start. We may lose all the plants that bees pollinate, all of the animals that eat those plants and so on up the food chain. Which means a world without bees could struggle to sustain the global human population of 7 billion. Our supermarkets would have half the amount of fruit and vegetables. It gets worse. We are losing bees at an alarming rate. Possible reasons include the loss of flower meadows, the crab-like varroa mite that feasts on their blood, climate change, and use of pesticides.

If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth's original 1100 mile per hour rotation speed at the equator. All of the land masses would be scoured clean of anything not attached to bedrock. This means rocks, topsoil, trees, buildings, your pet dog, and so on, would be swept away into the atmosphere. If the process happened gradually over billions of years, the situation would be very different, and it is this possibility which is the most likely as the constant torquing of the Sun and Moon upon the Earth finally reaches it's conclusion. If the rotation period slowed to 1 rotation every 365 days a condition called 'sun synchronous', every spot in the Earth would have permanent daytime or nighttime all year long. This is similar to the situation on the Moon where for 2 weeks the front-side is illuminated by the Sun, and for 2 weeks the back side is illuminated. This situation for the Earth is not the condition of ...

                 BFR mission Elon Musk is dreaming big. At the International Astronautical Congress in Adelaide today, Musk announced SpaceX’s plans for an enormous new rocket that he says will go to Mars in 2022 and maybe eventually provide speedy trips around Earth. The rocket, which Musk calls the BFR — the first and last letters stand for “big” and “rocket” – is smaller than the one he announced at the same event last year, carrying 150 tonnes compared to the previous design’s 300. It’s still more powerful than any of SpaceX’s or NASA’s other planned rockets. Musk said that he plans to replace all of SpaceX’s other space vehicles – the Falcon 9 and Falcon 9 Heavy rockets and the Dragon capsule – with this new system. “All of our resources will then turn to the BFR, and we believe that we can do this with the revenue we see from launching satellites and from servicing the space station,” he said. Once the BFR is up and running,...
