When you need some space… lets listen to @CheapAstro today for the answers of what’s the best solution to generate artificial gravity for long duration space travel? And what is the smell of space?
Don’t presume to assume. Did the Universe really start from a single point? How unusual is the Earth? Let’s explore the answer with @CheapAstro at #365DaysOfAstro
If we want a lunar orbiting space station, couldn’t we just send the ISS there? Could bacteria have hopped aboard the Venera probes and seeded Venus’ atmosphere? Find the answer with @CheapAstro at #365DaysOfAstro
Back in black. @CheapAstro dives head first into some more black holes. What’s in a black hole? Can you really have planets around a black hole?
Today at #365DaysOfAstro, @cheapastro questions some questions. Do we have the ability to measure the exact amount of heat arriving at the Earth from the Sun? & If we want a lunar orbiting space station, couldn’t we just send the ISS there?
Cheap Astronomy explores some old horizons and answers these questions. If the Big Bang happened 13.8 billion years ago how come we can still see it? How can we observe things that are receding from us at faster than the speed of light?
On the grand scale of things, galaxies are on the grand scale of things. How does the galaxy rotate? What is intergalactic dust made of? @cheapastro at #365DaysofAstro
E=mc squared is a nice straight-forward formula, indeed the energy-mass equivalence concept that underlies it is pretty straight-forward too. But why is that constant a velocity – and why is it squared?
