| Posted: 04 Mar 2021 06:26 AM PST I've been reading about the James Webb Telescope and struggling to wrap my head around exactly what "sitting at the Lagrange point" means. Does this mean it will orbit the Sun, following almost the same path as the Earth, but stay in the same place from the perspective of the earth? [link] [comments]  |

| Observed Light Speed from a Rocket Never Changes? Posted: 03 Mar 2021 08:32 PM PST Hello all, I've tried finding answers to a question I have on google but can't seem to find any that make much sense to me therefore I've chosen to write here for some clarification. Say a rocket moves away from Earth at 99% the speed of light and I then shine a laser towards that rocket. Once that laser catches up to the rocket, will it be observed to travel at 1% the speed of light since we are already moving at 99% the speed? I understand that the speed of light remains constant for everyone but if we observe it to travel at 100% the speed of light from the rocket, doesn't that mean that it is technically moving faster than the speed of light? I know my last point isn't true but I'm just having a hard time wrapping my head around the concept of light speed remaining constant regardless of your speed. Thanks! [link] [comments]  |

| What happens to an atmosphere that begins with flat initial conditions, and no forcing or damping? Posted: 03 Mar 2021 05:44 PM PST Let's say I implement the Navier Stokes equations in a solver for which errors due to numerics are negligible. The initial conditions are: -- isothermal for the temperature field -- zero for all velocity components -- everywhere flat geopotential If I presume that the surface beneath the atmosphere is rotating, what happens? Do I see evolution in pressure, temperature, etc. due to the Coriolis force alone? What if I turn off the surface rotation? Are the initial conditions then a steady state which remain for all time?

| What kind of tasks are Quantum computers better at compared to classical computers? Posted: 03 Mar 2021 08:13 AM PST I understand they are better at prime factorization which could make modern cryptography irrelevant. They also have many uses in the Biosciences like thing related to protein folding. What else do they excell at compared to classical computers? [link] [comments]  |
| Will Betelgeuse birth new stars when it finally goes nova? Posted: 03 Mar 2021 12:50 PM PST Considering the famed nova we are waiting for, I was wondering if the star is big enough to give birth to new smaller stars when it finally dies. I had a hard time locating information about this specifically. But is Betelgeuse a star with enough mass to do so or are the stars that could create newer stars already gone? [link] [comments]  |
| Posted: 03 Mar 2021 01:17 PM PST I'm not really sure which flair tag I should use here, since there's multiple disciplines that could apply to this question so I hope I'm doing this right. As far as the sciences go, this is less of a hard science question than it is a soft science question for the most part (as in, relating to things like anthropology, sociology, etc.), though there's probably a physics application to the question too since we're talking with different frames of reference with regard to time. Sci-Fi stories with multiple planets still do the "X years/months/weeks later" transition, even though planets of different sizes and rotations would have different calendars and would measure time differently. Considering the delivery of things like messages, goods, etc. is important--vital, even--for the functioning of a stable society, and since these things are all dependent on a common understanding of time, how would this actually work when entirely different yearly calendars and day cycles are used? Like, I can't wrap my mind around it. The closest point of comparison I can think of is the delivery of packages across different time zones here on Earth, which would mean that time zone differences would need to be taken into account, but that's just on a scale of hours and minutes, which are the same for everywhere. When you're talking travel to other planets, which have day/night cycles of varying hours which are different from Earth's 24-hour cycle, to say nothing of the adjustment of their respective calendars which could have more or less months than Earth itself, and that's not even getting into the seasons, let alone the fact that time would also be measured differently during the trip in space due to relativity. So how would we keep it consistent? What system would we use? It seems like a small thing, but considering the non-zero possibility of humanity leaving Earth to form permanent settlements elsewhere due to either exploration or lack of resources (assuming the species doesn't eradicate itself first), this strikes me as a pretty huge logistical problem (at least, as long as we're assuming that human society is continuous across the solar and extra-solar colonies--I suppose that if each planet were isolationist and kept to themselves, this would be far less of an issue). This has been bugging me for a while and it's going to bug me all day if I don't at least try to get an answer. [link] [comments]  |

| What causes radio emission for Sagittarius A*? Posted: 03 Mar 2021 08:48 AM PST I've read that radio source Sagittarius A* is a supermassive black hole. Why is it so "bright" in radio waves if EMR can't escape black holes? [link] [comments]  |
