We need to start spreading out, first in our solar system, later in our local cluster, then wide enough so no single cosmic event can kill all of us.

His argument was completely wrong. What’s the rational reason for having humans work dangerous jobs? Factory jobs? Etc.? Umm its obvious… robots can’t do those jobs.

His argument is irrational.

The true rational for sending humans off world is we need to do so. If you understand that, it is plain and if you do not, you likely never will understand why we left Africa. We are where we are because of the need to go and it does not matter if it was Europe thousands of years ago, or the moon in 1969, or venus, mars or any other place in space. We go, because we are human.

@Smee Self Hurry, maybe not. We know that our civilization will have problems due to the next glaciation starting in a few century. For our civilization to continue to grow, we need to go to space. As for cost, IF you knew what the government spent on the Apollo missions and the return on it, I doubt you would be so concerned. Let me give you one example. When was the last time you used a microwave. Almost all of the technology has its roots in the space program during the moon project. Tons of medical advancements also have their roots there. Any money we spend on the space programs eventually results in major advances in other areas of our civilization.

Given these two facts: - It takes 10-20 years to use the results of one robot mission to create and fly the follow on mission. - A human on site can adapt and do the follow on tests that would require several robotic missions. We can conclude that sending humans will speed up our progress by many decades. On a personal level, the speed up gives me some chance to see a definitive answer on Martian life in my lifetime. Using robot probes, I would have to upgrade to a robot body to have any real chance of seeing the answer.

My next big influence was Besters "The Stars My Destination" which I read in my early teens. I felt a pull from extra-solar system space. As I watched over the years I was dismayed by the slow progress of space travel and saw the Challenger disaster as a fatal blow toy chances of going into space. So I watch vicariously over the years. In the fall of 66 I went to boot camp in San Diego. We had watch duty at night guarding the clothes lines. My watch started at 2 AM. I walked out and looked up to see it raining stars. Little did I know this was a once in a lifetime event, but, it was a mind blowing sight. I reveled in it's glory the next two hours of my watch. I have watched many disappointing meteor events. My best description is driving at night on a dark road in pouring rain and the headlights briefly illuminate the rain drops.

I would say no, generally speaking. Their gravitational effects would really screw with the shape of a galaxy and eventually settle to the center anyway. Just like how Earth’s gravity pulls everything toward its center, the heaviest bodies will wind up being in the center of a galaxy. However, if a galaxy has just had a major interaction with another galaxy, it’s geometric center probably won’t house the biggest black hole. And remember that it takes millions to billions of years for galaxies to settle after situations like that, so when we look at all the galaxies we can see, some one them technically don’t have their largest black holes in their geometric center.

When mass is added to a black hole it's event horizon expands. So there's always space for more mass inside the event horizon ⚫. Now as to how stuff is packed inside the black hole we can't know as it's impossible for information to exit a black hole. So we don't (can't) know if it's just a more dense version of a neutron star or if the matter transforms into something even weirder 👾. We can't know if space-time inside a black hole behaves differently from outside or from the event horizon. There may be infinite time ⏲ everywhere inside, or no time at all. Entropy may cease to exist (no time for it 😮). The subatomic particles may fuse into something we can't even theorize about. It's all just going to be guess work until someone figures out to travel into a black hole, see for themselves, and come back out to tell the rest of us about it 😉

When you take two particles, say two protons, and push them toward each other you will find rhat their positive charges resist your effort. If you're using the electromagnetic force to push them, then the electromagnetic force keeping them apart will always eventually be just as strong as your push. No matter how hard you draw those two particles together, there will be some force or another that is strong enough to resist them getting smaller than a finite volume. But there's a way to cheat. Gravity acts on any mass over long distances, even if only relatively weakly compared to the other forces. So, if we collect enough mass together into one volume, the gravity of all that mass can really start to add up. If we give all that mass some momentum, say by surrounding it with a collosal explosion, then it will compress down to a density so extreme that gravity becomes by far the dominant force, and none of the forces that we know of inside of atoms are strong enough to overcome the crushing gravity. All that mass then has nothing that can stop it from continuing to collapse, continuing to get denser with stronger gravity, until the volume hits zero and the density hits infinity. Of course, known physics doesn't play well with infinite density and infinite gravity, so we dont know what the actual end state of a singularity is. It could stop collapsing at some fundamentally minimal volume that we don't know how to describe yet.

It does not actually take an infinite amount of time to fall into a black hole, otherwise they obviously would not grow or merge. If you controlled a spacecraft and got too close to the event horizon and ended up in a spiralling orbit you would fall through the event horizon, and then into the singularity, in a matter of seconds to hours, depending on your orbit. You are confused with the light that a distant observer sees: a frozen redshifted image (the light is 'climbing' out of the gravity well) of your spacecraft near the event horizon that exists for an 'infinite time', but will actually fade beyond visibility in a much shorter finite time.

Re: What can you melt on the surface of Venus: Note that it's the temperature of a pizza oven. So, you could have a lander that made pizza. Just drop down for 90 seconds or so, perhaps using a tether system, and you'll have a nice crust.

The next one to come in at an odd angle relative to our ecliptic, odd rotation characteristics, and then exhibit behavior that could legitimately theoretically be attributed to solar sail acceleration? I feel like those are low odds and chasing down something that left that many absolutely unanswered questions is worth at least poking with a stick to let it know you were there.

Although I have always been a big fan of space missions to the Moon, seeing the rovers on Mars and all but right now, before going to Venus or Mars, we need to go to Earth.

Kamino (answer). Hi Frazer, I listen to your Space Bites and podcast each week as I drive my route. My question relates to the DART mission... Now that we've touched the surface of an asteroid (Hyabusa), smacked an asteroid to change its course (DART), are there any plans to use a craft to apply a continuous-thrust to deflect an asteroid? I imagine the Hammerhead Corsair maneuver from Rogue One, powered by the upper stage of an SLS or Falcon Heavy. Thanks for everything you and the team do!

Question: I read that the moon is rising later every night. About 30-50min on average. I just realized that for like 10 days or so the moon rises only a few minutes later every night here. I was trying to find and an answer as to why but couldn't find one. My app shows me the following times. And I was also confirming my app times with my eyes. I am in Aland, Finland if that makes a difference. 2 October: 17:25 3 October: 18:16 4 October: 18:38 5 October: 18:48 6: 18:52 7: 18:55 8: 18:56 9: 18:57 10: 18:59 (...) continues like that and then back to normal 14: 19:24 15 19:51

For Bespin... I feel like I personally would love to see Betelgeuse explode more than any other astronomical event that comes to mind. A comet flying through the atmosphere and burning up is something that would be very cool, but in terms of frequency and how special the event is... Gotta go with one of the biggest known stars that's relatively close exploding. Supernovae in general are like a once in several lifetimes event (as far as we know based on ones we've been lucky enough to observe). Betelgeuse is relatively close by on a universal scale. It's one of the biggest red giant stars in the known universe, and scientists have said it could go supernova any year now (though it could take 100 000 years still because error). I'd feel incredibly lucky to view such an event, and its possible we could go many millions of years before an event of that magnitude happened again. Alternatively, in terms of things we could likely see on our time scale... I wouldn't mind being around to watch the ISS burn itself up when we're done with it. I've watched large, complicated space stations break apart, burn up and explode in KSP and I'd love to have the opportunity to see the real thing.

Tatooine: You can melt cotton candy on earth, just leave it in the rain...A flyby Venus would be great, but not if it delays going to Mars, do it as it's own thing, and yet still use the data to help with the Mars mission. I am 60 and have been waiting all this time to see men living on the moon, and a mission to set foot on Mars. Also we should get an international base on the moon. Coruscant: Yes there IS a good reason. To see if the human body CAN endure conditions on the Moon without loosing muscle and bone mass. Sooner we get people on the moon the more likely we will be on more than one planet or moon (Mars? Moon?)and survive a catastrophic mass extinction. Naboo: Cool, glad we deflected it slightly, maybe we can prevent at least one type of mass extinction. Alderaan: We need this, but we should also think of building it's compliment to cover the opposing hemisphere. Yavin: Saw a movie where "Nemesis' existed. Nemesis is just one name given for the mythic opposite Earth, not sure what name they used in the movie. In that movie written text was right to left and when held to a mirror was readable to us. Also there were identical people there, however if that person parted their hair on the left, then on Nemesis they parted their hair on the right. On Nemesis most people were left handed, where here most are right handed. Kind of cool, but still fictional. Geonosis: What is ALL Black holes disappeared? I mean what if the strength of all black holes increased by sucking up mass and it brought about a new previously impossible event that caused all black holes to collapse into themselves? Maybe it causes a new universe out side of our own to form and took all the black holes with it. Would that change the mechanics of this universe? would we even know about the creation of that OTHER universe (probably not) All we would see is that all known black holes disappeared. We would not know where or if other black holes ever existed as we have never seen them.

We have 2 equal solar mass black holes spinning at the same speed, one is collapsed from pure hydrogen, the other one is from pure iron. Will the 2nd one be more magnetic than the other, or does all matter loses its properties when it becomes a black hole?

IMHO the best way to terraform Venus would be if we could divert a few thousand comets to hit it. Nothing to big it would impact the surface of course. Not something we could do anytime soon but the only way to 'cool' the atmosphere and add enough water to allow microbial life to thrive.

Those picture of Diddimoon give me a question. All asteroids seem to be made up of broken rocks and dust and yet I haven't seen an asteroid which looks large enough to make rocks and dust. Are all these rocks remnants from much larger objects or 'ejecta' which has cooled down?

No, but they'll have mapped out the prospective landing site down to a few centimeters. So they'll pick a place that's flat.
