Was there a scientific reason behind the decision to take a picture of this particular black hole instead of another one ? Posted: 10 Apr 2019 10:57 PM PDT I wondered why did they "elected" this one instead of a closer one for instance? Thank you submitted by /u/Gethisa [link] [comments]

How would an array of Space Telescopes work? Posted: 11 Apr 2019 01:24 AM PDT The image of the Black Hole this week was made possible by connecting many ground-based radio telescopes, making an 'aperture' the width of our planet. What I wonder is; could a constellation of space radio-telescopes connect to make the 'aperture' larger, even solar system sized? Also, would increasing the number of satellites in the constellation increase the resolution of the image? submitted by /u/BGDDisco [link] [comments]

Are brain development timelines consistent across cultures? Posted: 11 Apr 2019 08:08 AM PDT I always hear how the prefrontal cortex (responsible for logical thought process/understanding long term consequences) isn't fully developed until age 25ish. What I wonder is if this has been checked in cultures where kids are given more responsibilities at younger ages than in the USA. Like is the development of the prefrontal cortex(and the rest of the brain) something that happens on a rough timeline like crawling and walking. Or is it developed through having life experience and receiving consequences from actions? Therefore, it develops later in the USA where kids aren't given many freedoms or responsibilities. submitted by /u/UniqueUsername718 [link] [comments]

Is the Schwarzschildradius of a black hole dependent on local curvature of spacetime at the observer's position? Posted: 11 Apr 2019 04:17 AM PDT So I think I have a pretty decent grasp of general relativity. For a long time I had problems reconciling the relatively weak gravitational forces experienced for an observer in a frame near the event horizon of a supermassive black hole in particular with the nature of the event horizon being this hard boundary that information cannot pass. I think I managed to solve that in my mind, knowing that the distance from the event horizon is observer dependent. Here's a thought experiment to illustrate what I think is happening: Consider you and a friend are at a "sufficient" distance (100,000 AU) from a black hole's event horizon (r = 1 AU) so that you are currently in only very slightly curved spacetime. Now you decide to move forward 100,000.1 AU (from your original frame) while your friend stays behind. You are now at a distance closer to the singularity than you originally perceived the event horizon to be, but you still see the event horizon being some distance away from you. You now shine a laser at your previous position. The light beam does pass the initially perceived boundary but never reaches your friend and curves back. Meanwhile, your friend will never see you passing past the 100,000 AU mark and will never see you shine the laser. ​ I understand that the initial "decision" to move forward 100,000.1 AU is kind of flawed as the distance you travel is dependent on the frame you're in and that shifts as you move closer to the black hole. My questions are this: - Is my assumption correct that you can knowingly move past the location of the event horizon you perceived from the initial resting frame and in your new frame still send information somewhat outside of that original boundary, just not all the way back to the initial frame? - Will your new position cause you to perceive a smaller schwarzschildradius than you did initially, or will it have the same radius, i.e. is the calculated schwarzschildradius just an upper bound for the radius perceived by a distant observer or is it observer invariant? submitted by /u/searingsky [link] [comments]

Why do telescopes and cameras use light instead of measuring other particles/waves such as sound or radio waves to form an image? Posted: 10 Apr 2019 11:12 AM PDT After seeing the EHT pictures of the black hole released this morning, I have been thinking about other methods which we could use to capture images (similar to thermal vision which measures heat and produces an image). One idea would be using radio waves to to sort of map out the bottom of the ocean where there is no light because of the depth. Is something like this realistic or already done or is there no way to form images out of radio/sound waves in a usable way? submitted by /u/Sassafratch [link] [comments]

AskScience AMA Series: We are scientists here to discuss our breakthrough results from the Event Horizon Telescope. AUA! Posted: 10 Apr 2019 04:00 AM PDT We have captured the first image of a Black Hole. Ask Us Anything! The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. Today, in coordinated press conferences across the globe, EHT researchers have revealed that they have succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow. The image reveals the black hole at the centre of Messier 87, a massive galaxy in the nearby Virgo galaxy cluster. This black hole resides 55 million light-years from Earth and has a mass 6.5 billion times that of the Sun Press conference right now! eso.org/live.

[Biology] Do probiotics actually work? Posted: 09 Apr 2019 10:53 AM PDT Full disclosure: I did study biochemistry and for that reason, I'm doubtful that probiotics actually work.

Could something be truly instant? Posted: 10 Apr 2019 04:26 AM PDT Nothing is instant, right? Not even light is instant, and light is the fastest moving thing we know of, (except it isn't really because shadows are theoretically faster) so wouldn't that make nothing instant? But if I were to drop something, wouldn't it be instant? I mean like down to the smallest unit of measurement we know, would something falling that length theoretically move instantly because there is no way it could move faster, right? submitted by /u/theosw [link] [comments]

How can there be enough photons released from distant objects e.g. stars and galaxies to form a constant image for an observer on Earth? Does wave-particle duality explain it? Posted: 09 Apr 2019 02:59 PM PDT Say you are looking at a star in the night sky, and you keep your eye focused on it while you step 1 metre to the left. While you move, the star would remain constant in your vision, surely meaning a stream of photons from that star was impacting your retina the entire time in every position while your head moved. Wouldn't this would mean there are a near-infinite amount of photons being released at all times from all sources of light in order for them to impact every position in space like this? Is that possible? Or is this explained by the fact light acts as both a wave and a particle? I feel I must be massively misunderstanding how light works/travels. submitted by /u/Fly_U_Fools [link] [comments]

How is the Whammy! board truly random? Posted: 10 Apr 2019 04:43 AM PDT Two people (Todd Newton and Press Your Luck host Peter Tomarken) have both said that the board currently used in the game show Whammy! is truly "Larson-proof". From all that I've read about computers, true randomness doesn't exist in computing since they just take a set of inputs and produce the same result every time for that set of inputs; they're deterministic. Are they exaggerating the truth (i.e. they say so because the algorithm is far too complicated for an un-knowing human being to crack in a reasonable time by obsessively studying the board's behavior), or does the board actually rely on true randomness? The only plausible explanation I can come up with, if the behavior is indeed truly random, is that there is a human being behind the stage who's actively interfering with the board's light patterns. submitted by /u/Misrta [link] [comments]

At the beginning of the universe. How? Posted: 10 Apr 2019 12:09 AM PDT So the universe and all the matter/energy contained within is thought to have somehow popped into existence (or possibly a rebound from a Big Crunch, etc.). Assuming it to be this simple, why would it not form a singularity from which nothing could escape? I understand C is not wholly relevant, since space is able to expand however quickly it wants, but surely all of the matter within that space (albeit super freaking small) would still be subject to gravity and the effects of that kind of density (black hole). You don't need infinite density (singularity) to have a black hole, just enough mass close together, right? (Because the temperature gradient suggests there was no singularity) Just enough for the escape velocity to equal C. I'm fairly certain the mass of the entire universe, and an unbelievable amount more (matter/antimatter), in a subatomic space would fit the bill. Lol Is it thought the space in between all of this matter and energy is what expanded, therefore effectively decreasing density to the point where matter could move outward freely? But surely the current velocity of galaxies suggests it's the matter that had velocity at that moment? I understand matter wasn't really a thing this early, but energy technically has gravitational effects, no? I guess i'm missing a crucial piece of information, if we have it. submitted by /u/JD32397 [link] [comments]

Why does the event of two black-holes merging send large gravitational "ripples" across spacetime? Posted: 09 Apr 2019 07:27 AM PDT I know that one of these events was used to confirm the existence of gravity waves, but do the two BH's actual merging emit waves that are stronger than are emitted in the aftermath of the event or is the "ripple" actually just the detectable start-point for the new SMBH's warping of space? What puzzles me is that black-holes are already infinitely dense, so how could the pressure from the merger produce temporarily an even higher density? submitted by /u/FanticalZappy [link] [comments]

How does the uncertainty principal relate to quantum fields? Posted: 08 Apr 2019 02:53 PM PDT The uncertainity principal states that the more you know about the position of a particle the less you know about its momentum and vice versa but that doesn't state anything about fields. The uncertainty principal also has something to do with quantum fluctuations and non commutativity but I don't understand this part of it too well. I know position and momentum don't commute but I am not sure why submitted by /u/182637777 [link] [comments]

How exactly does exercise induced hypoglycaemia occur in Type-1 Diabetics? Posted: 08 Apr 2019 04:54 PM PDT There seem to be mixed opinions on this as well as conflicting information on how exercise induced hypoglycaemia is effected by different types of exercise (lower intensity such as jogging and high intensity such as sprinting). Some of the papers I don't have access to, either, which further complicates the topic and makes it difficult to get an overview. Can anyone help out? Many thanks! submitted by /u/NT202 [link] [comments]

What results from fusion of He-4 + neutron ? Posted: 08 Apr 2019 12:40 PM PDT The following fusion sequence is well known: deuterium(d) + tritium(t) → helium-5 → helium-4 + neutron In this process the unstable helium-5 isotope is a required intermediate step in the process, that is, the d+ t fusion event does not go directly to He-4 + n, first a He-5 isotope must be formed. My first question is, is there experimental evidence for the reverse process ? If yes, during the fusion of He-4 + n is the unstable He-5 isotope observed or does the process go directly to d + t ? Second question. He-5 is unstable to alpha decay but is there experimental evidence to show that it is stable to beta decay ? submitted by /u/Loquadi [link] [comments]

How Does Global Warming Affect Hurricane Strength? Posted: 08 Apr 2019 05:35 PM PDT Does a hurricanes strength increase from higher ocean temperatures alone, or does it require an increase in the difference between ocean water temperatures and the hurricane system itself? If the latter is true does that mean that average ocean temperatures will increase faster than average air temperature? submitted by /u/troubled_duck [link] [comments]
