Could Neanderthals and other premodern humans been handicapped by being tongue tied? How could we find out or rule it out if it isn't preserved by fossils? Maybe by DNA? Rich ( talk) 06:57, 1 March 2024 (UTC)
In theory, if you were to go to the center of a cloud of hydrogen/helium gas in the middle of space, an area of gas that hasn't undergone nuclear fission, would it be possible to light the gas and start burning it? Assuming you have the oxygen required to actually light the initial flame, could you, in theory, start the process of fission through a simple handheld lighter? Or would the gas not ignite and simply remain how it is until it's compressed and undergoes fission that way? 71.38.197.194 ( talk) 23:08, 1 March 2024 (UTC)
To the 3 questions in short: No, No, agreeing No. Less respectfully, I ask the OP to review the wrong assumptions in their question. It's reasonable to suppose that given a handheld lighter, the OP can ignite the gas from a gas cooker. The gas goes on burning with a flame that emits light and heat, and you can assume that the atmosphere supplies sufficient oxygen under pressure to maintain the required stoichiometric ratio of fuel/oxygen. Each of the underlined terms that are relevant to a cooker in your kitchen are irrelevant and as assumptions misleading to understanding the fusion process in stars. That is a subject of intense research, both because it may become a practical power source if researchers solve difficult challenges of initiating fusion (needs high pressure and energy to start) and containing the subsequent reaction, and because science predicts that we can find the origins of chemical elements in star fusion. For that we are indebted to a landmark 1957 paper called B2FH after the initials of its authors. The best use for your hand lighter at this point would be to heat cups of tea for the hard-working fusion researchers. Philvoids ( talk) 11:14, 2 March 2024 (UTC)
