| How did a Space Rocket take off again from the surface of Moon? Posted: 13 Oct 2021 01:22 AM PDT I have seen many times in movies and other documentaries that when a space shuttle gets out of our atmosphere its propellers get detached and after flying for some time, it lands somewhere safely (Consider Moon). Now the question that has been troubling me is that if the rocket has no propulsion system to take off from the surface of moon then how does the rocket escape the Surface of Moon and how does it come back to Earth?

| What would happen if we removed too much CO2 from the atmosphere? How much would be too much? Posted: 12 Oct 2021 07:20 AM PDT Earth is a very fragile ecosystem and everything is about balance. One relatively minor event (on a planetary scale) can drastically alter our climate for countless years. We're starting to see this with global warming. Carbon capture is currently possible, however at the moment it's prohibitively expensive and not used very much. What would happen if we were started being carbon negative? Would we see an initial reversal in climate change to where we were pre-industrial revolution? What would happen if we kept going after that though? Would we have a slow global cooling?

| Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 13 Oct 2021 07:00 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Physics, Astronomy, Earth and Planetary Science Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience. If you would like to become a member of the AskScience panel, please refer to the information provided here. Past AskAnythingWednesday posts can be found here. Ask away! [link] [comments]  |
| How do scientists know where radio waves from space come from? Posted: 12 Oct 2021 09:13 AM PDT Recently read about scientists detecting radio waves from the centre of the Milky Way and it got me wondering, how do they know it was from there? It's probably an obvious answer but I can't find a direct one for it. [link] [comments]  |
| Can you see a black hole accretion disk with the naked eye? Posted: 12 Oct 2021 02:18 PM PDT If you would be close to a black hole could you see with the naked eye some sort of accretion disk? [link] [comments]  |

| how do gas stations/fuel stockpiles keep fuel fresh without it going bad? Posted: 12 Oct 2021 02:39 AM PDT Okay, Question here, gasoline can be stored up to 6 months if done correctly, diesel 3 months, you can add stuff to the fuel to stop it for about a year, that i know, but what about the GIANT fuel stockpiles.. they literally stockpile fuel for years?! How? Like the gasoline breaks down and looses it's combustible properties, Diesel turns into a goop when stored to long, what's the science behind the long term storage of fuel, bc I've searched around and only found that adding chemicals, but that for private use "long term" storage, I'm talking about gas stations that have fuel in the tanks for 4-8 years at a time, fuel stockpiles that have it indefinitely until used [link] [comments]  |
| Does 98 octane petrol means it is more polluting? Posted: 12 Oct 2021 03:28 AM PDT Was reading a news paper article. The writer mentions that 98 octane petrol is more polluting. I wonder if there is any correlation between octane level and pollution. [link] [comments]  |
