This was a SpaceX Falcon 9 Block 5 launch from Cape Canaveral that occurred around 1900 local time on March 4th, 2024. The photo was taken from about 65km from the launch site. The rocket was in the 2nd stage....
I’m thinking of things like heliocentrism where there was some modern discovery or revelation by science that invalidated a common assumption prior....
I love the phrase going down a rabbit hole, but it got me thinking, do rabbits even dig that deep to begin with? And what organisms (besides humans) might dig deeper that might be even more fun to tweak that phrase with?...
So I was day dreaming and I caught a thought. What if what we understand about physics is actually all there is to understand? What if you objectively cannot move faster than the speed of light because you can’t do the time traveling things necessary. This would mean that the only way to travel amongst the stars would be to...
We often talk about the climate impact based on greenhouse gases, but extracting fuel from the ground and using it in exothermal processes of course also releases energy as heat....
I assume it would break into smaller particles similar to the formation of microplastics. I hear about the effects of microplastics all the time. Are the effects of disposed rubber on the environment studied as extensively?
I feel like we are ways out from seeing anything like it. From what I’ve seen non-Newtonian fluids typically take a decent amount of energy to stop something and sound wouldn’t have much energy compared to something like a bullet....
Now that late spring/early summer is upon us, there's increasingly more headlines about less rain in various places (recent floods notwithstanding). I'm assuming that's because water is evaporating and not returning to those places, but where is it going?...
Was thinking about interstellar travel and the ability to provide artificial gravity by using a smooth acceleration and deceleration across the journey, changing from acceleration to deceleration at the halfway mark....
People talk of potential human flight on planets. Somewhere in the recesses of my mind I still wear my inner 5 year old’s caped Superman pajamas, stressing over how many stairs one must jump from to take flight. So is it possible to flappy bird a flying monkey?
I’m in NorCal and the weather has been all over the place this winter. It is hard to get a reliable forecast, sometimes even for the same day. I was wondering if it has something to do with the weather prediction models that were built before the climate change?
I recall an explanation of the formation of Jovian moons on the Harvard Smithsonian “CfA Colloquium” YT channel that casually mentioned how various elements freeze out of the solar wind forming ices, and this is the mechanism that allows formation of moons with large amounts of water and elements that are not found in larger...
Assuming we are talking about an era when Sol has a thriving space industry and the Solar system is broadly colonized. Current materials science supports structures up to 8 kilometers in diameter, and if large scale graphene production is possible, up to 100km in diameter, at least according to Isaac Arthor....
It is said that ACs are counterproductive in fight against global warming, in that while they may make the local environment temporarily livable, the greenhouse gases produced while making the electricity needed to operate them heat up the rest of the Earth by much more than the relief from the AC itself. By how much exactly is...
Does anyone have a list of long-term effects that may arise from periods of severe dehydration in childhood, particularly how this might affect overall health in adulthood?
I saw something yesterday talking about how Australia is geologically dead with the lowest tallest mountain range of any continent due to no landmass collisions. Does that make it the last visage of a supercontinent that everything else broke away from?...
