- In space, why can't you accelerate at 9.8m/s^2 (for like an hour or whatever) and then turn the vehicle around and decelerate at 9.8m/s^2 (for the same amount of time) - in order to simulate gravity?

- Sound waves exist in the third dimension as 2d waves, in all directions. Do sound waves exist in the 4th dimension, in all directions 3 dimensionally? Are we those waves? (Serious, no really.)

- If neutron stars are simply made only from neutrons, where do they get fuel to still support their glow? If normal stars fuse atoms to create energy then what is the energy-producing process of neutron stars?
- Is there a maximum number of times that a liver can regrow itself? Does regrowing reduce the functionality of a liver or does it always return to 100%?
- Why is it that, if the power series for f'(x) converges at an endpoint of its interval of convergence, the power series for f(x) will also converge at that endpoint?

| How do we know what dinosaurs' skin looked like? Posted: 20 Apr 2019 08:37 PM PDT Every depiction of dinosaurs shows them with leathery, reptilian like skin. Yet they say chickens are closely related to dinosaurs. How do we know dinosaurs didn't have feathers? Or fur? How do we know anything about their outer appearance from fossils alone?

| Do planets always form around stars? Posted: 20 Apr 2019 09:27 PM PDT Do planets ever form in space independent of a central star? Ie a small enough mass of dust that instead of a star forming at the center and one or more planets forming in orbit around it, just one planet forms and is an unassociated planet just floating around in space?

| What about a lack of oxygen makes a cell die? Posted: 20 Apr 2019 09:18 PM PDT Why does a lack of oxygen kill a cell? What is changing that causes this? [link] [comments]  |
| Is there a limit to how fast a black hole can spin? Posted: 20 Apr 2019 07:13 AM PDT If there is no surface on a singularity, is it exempt from the speed of light when figuring in rotational speed? [link] [comments]  |
| Posted: 20 Apr 2019 10:13 PM PDT Been thinking about this one for a while. Title is quite self explanatory. For example, two electrons forming a covalent bond due to opposite spins (1/2,-1/2), this spin is said to "overcome" the Coulombic repulsion between then and from RK this bond. But, from what I've understood and heard, which, mind you isn't a lot (only a highschool student) spin has no interactive "force carrier"/Guage boson or whatever your like to call it. So, my question is, how does the spin of one particle interact with the spin of another and overcome this repulsiv electrostatic force... If it isn't a force and only a sort of angular momentum symmetry??? It's just really been bothering me. Any explanation will help, thanks! [link] [comments]  |

| How does bacteria exactly evolve to be antibiotic resistant? Posted: 20 Apr 2019 06:37 PM PDT I just cannot wrap my mind around this. How does giving someone antibiotics encourage the bacteria to evolve to be antibiotic-resistant? If someone already has even a little antibiotic-resistant bacteria, then antibiotics are useless anyways, right? So if someone doesn't have antibiotic-resistant bacteria, then antibiotics should kill all the bacteria, right? Why should we worry about it evolving if it is all dead? [link] [comments]  |

| Why do they say that impedance slows down signals in a wire? Posted: 21 Apr 2019 05:06 AM PDT Impedance should only be about current resistance no? A wire with more impedance would have less current than a wire with lower impedance, but I don't see how the signal speed isn't the same for both. Why does it change the speed of a signal? This means the more impedance a wire has, the fewer Hz my signal's wave must have or it gets "muted"? [link] [comments]  |
| How does computer fill the CPU registers with the data fetched from the memory? Posted: 20 Apr 2019 04:32 PM PDT Hi, I want to understand what happens at the hardware/electric circuitry level. For example, how does computer know that this particular 0 bit goes to the X transistor/gate in the register cell A, and that particular 1 bit goes to Y transistor/gate in the register cell B. How does computer organise massive amount of bit/data allocation? I know that memory and CPU are connected via data bus. Is this data bus actually a collection separate wires or one single lane to different parts of CPU? Thanks for your explanation [link] [comments]  |
| Posted: 21 Apr 2019 03:42 AM PDT If you were a 4th dimensional being, could you make sound 3 dimensionally? How does it exist? What is it? A 5th dimensional being sees all 3d beings as 4d objects. Therefore, they could make 3d sound waves, right? [link] [comments]  |

| Posted: 20 Apr 2019 02:29 PM PDT Title more or less says it all. My textbook stated that "it can be shown" that this is true, but didn't show it, and google has turned up nothing. [link] [comments]  |
