Thanks! Great video. But it raises additional questions. How do I know that the ruler is stretched? One tickmark is still one tickmark. Do I have an unstreched ruler to measure the stretched ruler with? Does for instance the speed of light change over time relative to the expansion of the universe?
I guess I'm missing a step in the explanation. More redshift means moving away faster. But how does that directly translate to distance? It could be close and move away fast, right? Do I need coffee?
That treason you saw happening, live on TV…It happened. And the guy who made it happen … he did it.
THIS IS HUGE! Researchers at Harvard Medical School have developed a nasal spray that in preclinical studies, offered NEARLY 100% protection from respiratory infections by COVID-19, influenza, viruses, AND pneumonia-causing bacteria. Let’s talk about that! 🧪🧵⬇️
Gonna call myself a scientist from now on. ^^
There are a fair few people on here who want fascism, though they may not put it so bluntly, because they think resisting it will give their life meaning and I am *begging* them to read primary sources about living under fascism.
