Sound waves cannot travel through a vacuum. If black is only the absence of color then how does the color black exist in our day to day? Itâs made of galaxies, stars, planets, black holes, comets, asteroids, and all the other cool space stuff!â Yes, there is a lot of amazing space stuff, but if we add it all up, itâs just a very small part of the entire universe. A place to discuss relevant topics in civil and military aviation, space exploration, and news relevant and interesting to those with a passion for all things flying. I guess I donât really know what Iâm looking for. Yeah you explained it well. Indeed, the history of physics so far might make us doubtfulâbecause it seems as if whenever we learn more, things just get more complicated, at least in terms of the mathematical structures they involve. When I turn off the lights the absence of light makes it too dark for me to tell what color turning off the lights turns my room. In the abstract itâs far from obviousthat there should be a simple, ultimate theory of our universe. Press J to jump to the feed. "A liminal space is the time between the 'what was' and the 'next.' The black you are seeing just means the light coming from that direction is too faint for our eyes to make anything out of it but black (the lack of any light). ( Iâll also be taking physics E&M is that plays a part). Reddit is a network of communities based on people's interests. Does anyone have a similar experience? Astronauts live and work there. Objects with more mass have more gravity. Albert Einstein described gravity as a curve in space that wraps around an objectâsuch as a star or a planet. Image credit: NASA. If another object is nearby, it is pulled into the curve. I thought I would be doing more experimentation, but so far it turns out to mostly be computational. We might not ever truly know what the "scariest movie ever" is. I feel like I just want to get the MS and leave. What Is Space Weather? But thanks to science, we now have a better idea. 'Outer space' begins about 100 km above the Earth, where the shell of air around our planet disappears. Press question mark to learn the rest of the keyboard shortcuts, Aerospace Engineer - Systems/Mission Analysis.

Space aliens have reached an agreement with the US government to stay mum on the experiments they conduct on Earth â as well as their secret ⦠Both social media sites are places to share content. How would spacetime change our understanding of space and time? What is Space-Time? Directorate. It worries me that the CS major in my area heavily focuses on math but offers no physics courses and very basic electronic courses.Aerospace has a little bit of everything. About Community. Einstein showed that space and time are essentially the same thing, a single entity called 'spacetime'. Space isn't black either. We do not support the Find communities you're interested in, and become part of an online community! Or advice? r/Art: This is a subreddit about art. It turns it pitch black. Learn how to make this eggnog recipe, which is now a favorite on Oh I thought it was full of matter and antimatter meeting and destroying itself. But space and time seem so radically different. Here's a Big Compilation of my personal favorite edits that I have made, tell me your opinions and criticism in the comments if you want, Happy Blue Friday Everyone, and GO HAWKSð¥ðððð¥ Welcome to Reddit, Seattle's Space Needle put on a surreal and colorful virtual light show for TV viewers ringing in the New Year from the comfort of their couch. Spacesuits protect astronauts in space, on the moon and on other planets. In space, no one can hear you scream. See also Olber's paradox (the solution of) for an explanation of why it's not bright. My interests are too many but l can imagine myself working on telecommunications,DSP etc. But still, us humans still assigned that absence a name. Aside from a speck of tiny dust here and there, nothing. Multiple missions will explore Mars, new telescopes will begin observations and plans are underway to return humans to the moon by 2024.The However, the content is shared on each site in very different ways. This might be a surprise, but we donât know what most of the universe is made of. Turning off the light in your bedroom doesn't turn it purple. My main goal is to work in the space sector eventually, for example in a CubeSat startup in Europe.I dont rule oute anything else ofc. I read somewhere that the average density of interstellargalactic space is about 1 hydrogen atom per cubic meter. SpaceX engineers holding a Reddit AMA on Starlinkâs Better ⦠This is because there is no air in space â it is a vacuum. When it comes down to it will taking BC be better than AB in the long run? 4 days ago. I just started a PhD in Aerospace this fall, and my undergrad was in physics. Hi, I am familiar with both sites; I can answer your question. I constantly feel like Iâm behind and that Iâm unqualified to be where I am. You might be thinking, âBut of course we do! Iâm trying to apply for internships, but I donât have many of the required competencies since my BS was in physics not aero (controls, vehicle design, etc). It appears redder than most brown dwarfs, and is likely much younger than most, too. Space isn't black either. The black you are seeing just means the light coming from that direction is too faint for our eyes to make anything out of it but black (the lack of any light). Made In Space made its first ceramic part in orbit with the help of 3D printing aboard the ISS. The dust isn't space, it's just in space. It turns it pitch black. Black ISNT a color, it’s just the absence of light. But if you DO get into quantum mechanical gibberish, the answer changes completely. Space is not empty, it’s frothing and bubbling with activity. Explain Like I'm Five is the best forum and archive on the internet for layperson-friendly explanations.

Earth's next-door neighbor is often called the Red Planet because of its red soil. Some call it space trash, others refer to it as space junk or space debris.All three terms identify the same items -- man-made objects remaining in space though they no longer serve any useful purpose. share. Hello, Iâm a junior in Highschool and next year Iâm going to take calculus and right off the bat I wanted to take BC cause i thought it would better prepare me for college considering how difficult the classes can be. Space has no colour. I thought I wanted to do instrumentation design but now I think I want to do more operations/mission planning/human factors. A black hole is a place in space where gravity pulls so much that even light cannot get out. Is that incorrect? This object could have formed just like a brown dwarfâfrom a small cloud of gas. New comments cannot be posted and votes cannot be cast, More posts from the explainlikeimfive community. Gravity also gets weaker with distance. Stuff in Space is a realtime 3D map of objects in Earth orbit, visualized using WebGL. Stuff in Space. save. From what I understand of physics, it’s not “nothing” that we see that makes it black, it’s anti-something. It does not have zero energy, so depending on your definitions it may even be said to have a color. Turning off the light in your bedroom doesn't turn it purple. Some scientists are calling this object a planet. Anything that has mass also has gravity. Letâs start with the similarities between Reddit and Facebook. I canât bring myself to do more than a couple hours of research a day (itâs winter âbreakâ, so Iâm supposed to be doing research full time) and I donât know if itâs because I donât like the research or if itâs just working from home and being in a new program.
