space noob

Stupidly I can answer this question by telling you what I thought they were before I got into astronomy, when all I had was a GCSE in science, I thought a black hole was like a rip in space, like a tear where time and space itself just didn't exist because the supernova had destroyed anything that existed there before, we still don't know what a black hole actually is, we know how it's created and how it interacts with the universe, we know that they help shape galaxies, some scientist don't believe they should exist and some even don't believe that they do, I've heard intelligent men even refer to them add dark energy stars

I've heard neutron stars can rotate 500 times per second, I don't know if it's true, it sounds so incredible that it could be one of those space facts that is made up just for the sake of it but I can also apply this question to hypervelocity stars there is a neutron star named RX J0822-4300 which is moving through the milky way, this star travels at 3 million miles per hour, As the faster you travel -the more you weigh would this neutron stars mass get multiplied travelling at this rate? Another question to add to the previous would be whether in space, the speed of travel affect the weight of an object and perhaps friction is needed but there are still atoms in dark matter but just spread much further, I think it's three atoms to every cubic centimeter Just for the sake of it I'd like to know if anyone thinks a hypervelocity black hole is possible, although it would take one hell of a force to move one

This is a good question, scientists everywhere believe that orbiting an object with a super large mass is the quickest way to travel forward in time, i'm not sure about the time being stopped thing but I don't see it being likely, you would probably have to be inside the event horizon for this to happen and you would never get out to witness whether time had stopped

According to Einstein, at the end of a big bangs life cycle, there is believed to be a big crunch, the universe goes back to the point of which it originally came into existence, most believe that after a big bang-big crunch, another universe is created, if the point of the big bang is anything like a black hole which it more than likely is, due to the enormous amount of matter it has produced over nearly 14 billion years, then it's possible that our universe would go through the event horizon and matter would form in a different universe, this universe could occupy the same space or move entirely, creating a new big bang, Einstein believed that after the big crunch the second universe would be the same as ours but it would go backwards in time, this is debatable, due to it being "all relative" if we were in the backwards moving universe then it would still be how it is now, with no changes, we would experience it in exact the same way- from birth to death, your question relates to everything theoretical physics is working towards and it will either take a long time to figure out or we may never be able to Something that had crossed through my brain before is that dark matter may be unbounded by time, or time may not affect it, so if dark matter is everywhere then time would not exist and would have started at the big bang or at any point when matter comes into existence, gravity has an effect on time but things like dark matter aren't affected by gravity, so time would also behave differently to dark matter, if you had a ball of dark matter, it wouldn't really be a ball of anything, so if before the big bang there was just dark matter everywhere then could you really say that there was something before the big bang? As a lot of people said before me about whether the universe is finite of infinite, I believe everything can be measured and the belief in an infinite universe should have went out the window when the big bang theory came into place, the infinite universe is more suited to the steady state theory than the big bang theory

When you got to the center you would experienced zero gravity not to mention a lot if pressure that I don't think one could survive, you would get stuck

I'm thinking why would they? If earth found another planet with intelligent life then we would survey it just to weigh up possible risks, but it wouldn't take long to contact them, to beings in another system, earth would be facing towards the sun and have it's back to them so even finding earth would be hard when it's dark to them, possibly playing the Beatles out in to space may have attracted their attention though, I believe that at the point where humans are advanced like we are now is like going up on a chart, at the bottom you have your poop slinging monkeys, in the middle are your cave men and near the top is us, the very top of the graph would be a more advanced species, I don't think we can become highly advanced in a way that resembles sci fi super intelligence, so a species with the means to survey us seems unlikely to me, it could also drain a good bit of a planets resources to launch an operation of that extent, like I said at the beginning there isn't really a reason to, if they where wanting to attack earth from light years away and they had the technology to survey us like that then they could probably do it off their own planet

Nature will try to help us evolve to live on a different planet once we purposely took ourselves there, nature is lazy and will find the quickest way possible, at first we would have to learn to survive by our own means until evolution makes things easier, if we found An atmosphere like earths then the only things that would change would be ways of evolving to deal with things like changes in gravity and temperature differences, if a planet was found it could possibly take hundreds of thousands of years to get there, if any planets where close that were habitable then we would know by now, the planet in question would have to be in the Goldy locks region (just the right temperature- aptly named) this doesn't technically have to mean distance from a star but whether it's atmosphere helps to support life by blocking some heat from the star or allowing more in, finding a planet with an atmosphere which could possibly support life will be a hard task in itself there are so many ways for atmospheres to be destroyed that it's a miracle earth has one and scientists believe life started to exist on earth when it became habitable, so the planet we found could have life already on it, if it's as advanced as ours or more advanced then we wouldn't stand a chance attacking

vy canis majoris, a star that is undeniably a billion times larger than the sun, however it will burn up much quicker

It depends on whether you could survive being crushed, I don't think survival is likely, or better put, I don't think it's even possible, the black hole would contain so much mass that anything anyone in the universe could create a craft strong enough to withstand that amount of pressure, black holes destroy stars, stars contain unbelievable amounts of energy that we could never even begin to recreate, I think I read that it was something like 1,000,000 nukes per second, it could possibly be more, if a star can't push against the pressure from the black hole and defeat it by exerting more energy than the black hole could crush then I don't think anything could, the black hole at the centre of our galaxy is about the swallow many stars and gas clouds, however some energy will escape but it would not have passed through the event horizon at this point, the black hole in the centre of the milky way is a super massive black hole, we can't compare this to the standard black hole, for the record for someone who said black holes are dark things in space, your wrong, black holes are actually the brightest objects in space, their unbelievable mass can pull in light

It's possible that if our universe exists inside another than ours could possible take up the same amount of space in that outer universe in comparison as what an atom would take up in ours, we currently believe that the universe is finite, we know that in order for a vacuum to exist it has to have an outer "case" it's possible the case could be the matter from another universe pushing back on ours from at a greater mass, which makes it far more possible that it could be a much bigger universe, the fact that our universe could be the basic standard size for an average universe, some scientists believe that the big bang could have been born from a black hole, which would mean our universe just entered into the space it occupies now, making it more likely that all standard atoms, planets, stars and galaxies roughly follow the same standard size
