| Posted: 16 Jul 2021 04:00 AM PDT Two years ago, we captured the first image of a Black Hole. Ask Us Anything! We'll be answering questions from 11:30 AM - 1:00 PM Eastern Time! The Event Horizon Telescope (EHT) - a planet-scale array of eleven ground-based radio telescopes forged through international collaboration - was designed to capture images of a black hole. Two years ago, EHT researchers successfully unveiled the first direct visual evidence of a supermassive black hole and its shadow. The EHT recently released a new version of the historic image, now shown in polarized light. As we continue to delve into data from past observations and pave the way for the next-generation EHT, we wanted to answer some of your questions! You might ask us about:

| How do intercontinental bridges/tunnels take tectonic plate movements into account? Posted: 16 Jul 2021 07:21 AM PDT I would assume that being attached to two continents moving away from eachother would slowly but eventually tear the structure apart. [link] [comments]  |
| How does combustion power a rocket? Posted: 16 Jul 2021 04:24 AM PDT From my understanding a rocket works because the exhaust being pushed out pushes back on the rocket. So why exactly does lighting it on fire make it faster? [link] [comments]  |
| Posted: 15 Jul 2021 12:47 PM PDT Original COVID-19 variant reproduction rate was estimated to be around 2.5-3. Now we deal with the variant twice as transmissible. I often hear that influenza mutates at a faster rate compared to COVID-19. When it comes to flu it seems that worst strains ocassionaly get to around 1.8 r0, but mostly it's around 1.3. Why flu doesn't mutate gradually towards more infectious forms? Most infectious strains actually seems to fade and strains that are both less infectious and deadly seems to take off during some seasons, which is kind of counter-intuitive for me. When it comes to COVID-19 is there any hope that future variants will be less infectious and deadly? Or we are more likely doomed with crazier and crazier mutations? [link] [comments]  |
| Posted: 14 Jul 2021 11:59 PM PDT I know that it's possible to determine if a woman has given birth vaginally based off the pelvic bone, but have yet to find an answer on if you can tell how many times? Furthermore, even if she had a C-Section would any shifts in the pelvis reflect her body had carried a child at any point? [link] [comments]  |
| When you receive a transplant from the opposite sex, would that organ grow differently? Posted: 15 Jul 2021 12:40 AM PDT Would the donor organ's cells reproduce as if the recipient is of the donor's sex, or would it conflict with the genetic material of the recipient, or would it not have an effect at all?

| Do lungs fill top to bottom or bottom to top or all at once? Posted: 14 Jul 2021 10:32 PM PDT Hi ,when we inhale, does the air fills up the bottom of the lung first, or top of the lung first, or all at once first? Similarly , when we inhale, does our chest rises first, or stomach expands first, or stomach and chest expand at the same time? What about exhale? [link] [comments]  |
| How long does a normal 500ml bottle take to empty? Posted: 15 Jul 2021 02:46 PM PDT The world record for drinking 500ml is under 2 seconds. If one were to take a 500ml beverage bottle filled with pure water and turn it upside down, how long will it take for the water to flow out completely? [link] [comments]  |
| Did human beings evolve from fish-like organisms? Posted: 14 Jul 2021 09:07 PM PDT I know a lot of creationists find it hard to believe, but does the current scientific consensus say we evolved from fish-like organisms long ago? [link] [comments]  |
