| 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
We are a group of researchers who have been involved in this result. We will be available starting with 20:00 CEST (14:00 EDT, 18:00 UTC). Ask Us Anything! Guests:

| [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. I do have friends who have started a probiotic regimen and have seen results. Does the science back this up? [link] [comments]  |
| 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?

| Are people really more likely to buy something that costs $19.95 vs $20.00? Posted: 09 Apr 2019 07:09 PM PDT I've always figured that the odd pricing was given to have more people buy the product, since $20 is a more round number than $19. Is this the case? Is there evidence to back it up? Is something else completely different going on here? [link] [comments]  |
| 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. [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.

| 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. [link] [comments]  |

| How does immunoglobulin therapy help to treat erythroblastosis fetalis? Posted: 09 Apr 2019 09:41 PM PDT I don't understand how IgG anti Rh antibodies would help to treat erythroblastosis fetalis. Could someone explain? [link] [comments]  |
| Posted: 10 Apr 2019 12:48 AM PDT I guess I was just wondering if the sound barrier acts as a literal physical barrier in regards to achieving supersonic speeds? [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? [link] [comments]  |

| Could a red dward form in a protoplanetary disk? Posted: 09 Apr 2019 03:32 PM PDT A common way to distinguish between a large planet and a brown dwarf is the method of formation with a brown dwarf forming through the collapse of a nebula and a large planet forming around a star in the protoplanetary disk. Is it possible, or are there any confirmed cases, of a red dwarf forming the way a planet forms; from the material surrounding a (probably larger) star? [link] [comments]  |
| Can a plant be stung by a wasp/bee in a hurtful way? Posted: 09 Apr 2019 10:19 AM PDT I just saw a Venus flytrap trap a wasp, and I saw the insect stinging away, also on the plant. Will this do something? [link] [comments]  |
| What would happen if a large mass and a small black hole collided at extreme speeds? Posted: 09 Apr 2019 06:54 PM PDT If a small black hole (eg the black hole from XTE J1650-500, or even larger) and a giant star (eg Betelgeuse) were speeding towards each other and directly collided, what would happen? Would the black hole be smashed apart/dissipate? [link] [comments]  |
