| Posted: 09 Mar 2020 05:58 AM PDT How has it expanded so fast, if matter can't go faster than the speed of light? Wouldn't it be a maximum of 27.6 light years across if it expanded at the speed of light? [link] [comments]  |

| Posted: 09 Mar 2020 04:00 AM PDT Hi Reddit! This is my first AMA so this will be exciting. I am the principal investigator of The Matter Lab at the University of Toronto, a faculty Member at the Vector Institute, and a CIFAR Fellow. I am also a co-founder of Kebotix and Zapata Computing. Kebotix aims to disrupt chemistry by building self-driving laboratories. Zapata develops algorithms and tools for quantum computing. A short link to my profile at Vector Institute is here. Recent interviews can be seen here, here, here, and here. MIT Technology Review recently recognized my laboratory, Zapata, and Kebotix as key players contributing to AI-discovered molecules and Quantum Supremacy. The publication named these technological advances as two of its 10 Breakthrough Technologies of 2020. A couple of things that have been in my mind in the recent years that we can talk about are listed below:

| Will we ever be able to "see" the cosmic microwave background radiation? Posted: 08 Mar 2020 11:37 AM PDT As I understand it, the cosmic background radiation leftover from the big bang is currently in the microwave spectrum, but is constantly redshifting as the universe expands; so logically that means eventually it will redshift enough to be in the visible spectrum. Does this mean that at some point in the distant future we will actually be able to see it with the naked eye, and what would this look like? (Assuming of course we survive that long as a species) [link] [comments]  |
| Posted: 09 Mar 2020 04:44 AM PDT In some movies, people go to other planets and for numerous reasons, they age differently than people on earth. Some say a few actual hours on these planets can actually be years on earth. I understand the concept that time is calculated differently on other planets but can anyone go to another planet and come back to earth physically younger? [link] [comments]  |

| are there any large systems of planets that orbit a bigger planet rather than a star? Posted: 09 Mar 2020 03:06 AM PDT I suppose that would just be a rouge planet with a lot of moons but does it happen often? could you find planets with the size and quantity as the ones in our solar system orbiting one the size of jupiter? or would they all just drift away or crash into eachother or something? (sorry if this is a dumb question) [link] [comments]  |
| What is the probability that a rolled d10 has a higher role than two d20's? Posted: 08 Mar 2020 02:09 PM PDT I'm in need of a good statistics mathematician. I was rolling some dice playing DnD and was wondering how to figure out this question about probabilities. If I roll 2 D20's and 1 D10 what is the likely hood that the D10 roll is a higher number than both the D20's (indivudally, not combined). For example, one d20 is a 5, the other d20 is a 6 and the d10 is a 7. [link] [comments]  |

| What would cause explosive "pleating"? Posted: 08 Mar 2020 08:06 PM PDT While seeing this image of a test explosion of the UK "Grapple Y" nuclear missile, I noticed the "pleating" (for want of a better word) on the shaft of the mushroom cloud. It's the first time I have seen this sort of formation, and I was wondering what would cause it? My guess would be fluctuations in explosive force, but I can't see how that would happen here.

| Could there be more unknown elements that exist in the universe? Posted: 08 Mar 2020 05:30 PM PDT Here on earth we have encountered a number of elements that are known to us. Is it at all possible for there to be more naturally occurring elements in the universe than the ones we've already discovered? [link] [comments]  |
| Do you weigh more on earth than scales actually tell you because the earth is spinning? Posted: 08 Mar 2020 10:13 AM PDT Like should the force from f = mv2 /r be added on to the weight you measure yourself with scales? Edit: you know what equation I mean I don't know how to format [link] [comments]  |

| Why does Morocco have so much phosphate? Posted: 07 Mar 2020 07:32 PM PST I read that Morocco/Western Sahara has 75% of the world's known phosphate reserves, but a google search didn't turn up an explanation of how it all ended up there [link] [comments]  |
