What if. Black holes weren’t really holes? Maybe they are collapsed neutron stars where everything is compressed to the neutron level because the gravity is so great. Maybe everything that gets sucked into the gravity well gets smeared across the surface where the gravity crushes it into its atomic components, and the radiation given off is the energy released as atoms get broken down into neutrons. Isn’t there a fountain of particles, “light”, and radiation coming from the polar axis on most “active” black holes? Are these particles moving faster than light since they are escaping the gravity well of the “black hole”? If a “black hole” has eaten everything around it isn’t it completely dormant until it runs into something else? Maybe after it gains enough mass it reaches a critical point that could be simulated. Then it explodes into a supernova, and in the process creates everything out of the “nothing” that neutrons are. A big bang as it were?
What if the world were made up of two races. Not color, weight, height, intelligence, wealth or power, but Man or Woman. I have often thought about how truly foolish we are as humans to not realize that men are men. Black, white, yellow or green. Men are men.
On the other hand. Men are NOT women. Men. But then I realize that human is human. Man or woman? Black or white? How about just being human. Human is human. As a human, I wonder what if we really didn’t need any sleep? No sleeping, ever. Yet, always feeling refreshed and alert. What if our brain is kept alive by a beam of light trapped in our head?
All women want Cheap Fashion Handbags . Since all the stars and we want as fashionable. Owning a leather bag by a famous designer is a dream for most women. Wear a leather handbag in different occasion, though, to you. He says, you can choose from the category of things For me there is only one reason to buy a replica or designer inspired handbags You can get quality at affordable prices. You can learn a lot about a person from the clothes they wear, but you can learn a lot about a person, just hand that they wear.
You have the understand,
before the bigbang, there was no universe. The bigbang created space and time, so to give a specific place at which the universe ‘banged’ is impossible, as really the expansion started everywhere in the universe at the same time, there is no central location. To your other question, no matter probably exists outside the bubble than we can observe. The only only problem is since it cannot interact with us (is unobservable), it has no effect on us. Different places in the universe, will have different observable universes as well.
Thank you for making a science show that is as exciting as Bill Nye the Science Guy. You have gotten me re interested in science when times where hard for me. I was wondering about the show you did with the blackholes. (unless I saw it on another show) If there was a big bang, and little bangs caused galixies to form but the explotion left blackholes, then shouldn’t there be a blackhole left by the big bang?
I asked my dad about demestacated animals some time ago and I would like to have some things cleared up. Why do demestacated dogs looks different then wolves? What happens in their genes that causes them to change? My dad told me that when wolves let themselves become tame then their offspring would look more like today’s dogs rather than wolves.
I would love to ask/tell you all of the questions that are in my head but it would probably be to long.
I probably got somethings wrong but it doesn’t hurt to ask. right? Speaking of asking, would it be posible for me to meet Mr. Tyson in person, for a day?
Thanks for reading what I wrote (sorry for all of the misspelled words) and I hope to have a message from the show soon.
You could in theory stop moving relative to other celestial objects, but you can’t just stop. What ever momentum effected you to move would continue indefinitely since there are no particles in space to create friction.
Although time is relative short of moving at Tachyon speeds, anything less than the speed of light, or close to it would not have too much of an effect on your age, or time. Yet anything under the speed of light would take so many years to get to that point in the universe it wouldn’t much matter for a living organism, you’d be long dead.
If there was a ‘plane’ of pure existence, where everything that will ever be, is and has always been. Could the Big Bang theory be a collision of waves of existence? Is is possible that like the fabric of space time, there is a fabric of existence that all things are apart of. When these waves collide they spark a process that leads to the creation of a universe?
I suppose like a boiling pot of water. The multi verse is in the pot,
and every bubble is the effect of a collision of these waves creating a universe. As the bubble expands entropy runs it’s course and it pops.
Not the perfect metaphor, but I’m sure you get the idea.
thats a good question. Scientists know this because the whole universe is made by elements that are on earth. how do we know this? well every star fuses hydrogen into other complicated elements,such as helium, and carbon, and these elements are spread out. so there is no way that the other life forms are used to anything completely different from earth’s because they are exposed to the same material that made our bacteria, etc. Maybe there are subtle differences, like being silicon based, rather carbon, but that won’t be that shocking, since the elements are close enough in properties.
first of all, the event horizon is not eliptically shaped, the only reason bodies orbit it eliptically, is becaue of the angel in which it countered the dark hole. second, the one falling might have a slight chance seeing it since he is closer to the light that is trapped observers have no way to see it. third, the maximum speed is the speed of light. fourth, it depends how much debree got in the dark holes and it depends on the size of the dark hole that being said the answer is no there is no limit. Dont forget though, that the dark hole sends out enormous jets of energy from its center as it eats up more matter. No Dark hole is big enough to suck in an entire galaxy, and as for our solar system, it has an odd cycle as it rotates around the galaxy so that it never will reach the center( where the dark hole lies).
What if you pointed your spaceship out away from everything? You leave this galaxy and then every other galaxy behind until the entire universe appears as nothing more than a single star in an empty black void.
Does such a place even exist? if not, why not?
if you could go out far enough to fully escape the gravitational pull of the universe and then brought your spaceship to a full stop what would happen? If your movement through time is relative to your movement through space and you move through time slower the closer you get to the speed of light, how much faster could you move through time if you managed to stop all movement?
Question 1. Would the shape of the “event horizon” where nothing escapes be elliptically shaped?
Question 2. Would the falling object know it passes into the “event horizon,” or is that something that can only be observed from outside the horizon?
Question 3. As things spiral in, they accelerate to enormous velocities. Is there a maximum speed? Would they continue to gain in mass as their velocity increases per Einstein’s theory?
Question 4. The temperature must rise as matter is compressed into the hole. Is there a limit to the temperature?
Question 5. There is an enormous black hole at the center of our galaxy. Given enough time, won’t everything in the galaxy be sucked into the hole?
What if we had all the genetics of a certain organism (squirrel, elephant, human, etc) being alive of course at certain various intervals in time what could we figure out? After, possibly apply it or include it with population growth and density, and land mass to determine when its environment will act naturally to equal out a rapidly growing organism (reduce population?). [because of more people].” People are made from the same matter that has been on the earth since its formation, so, there is no displacement with an increase in a species’ population. Maybe the earth is heavier from space matter impacting it over the eons, but people would only have an effect on the earth’s weight if we came from outer space and landed here. satellites, space stations, etc.
What if pandemics were bioengineered? Considering the potential risk of the A/H1N1/09 virus, I found the following study strangely coincidental. Air Force released Air Force 2025 “a study designed to comply with a directive from the chief of staff of the Air Force to examine the concepts, capabilities, and technologies the United States will require to remain the dominant air and space force in the future.” In the unclassified study, the College of Aerospace Doctrine, Research and Education at Maxwell Air Force Base in Alabama posed several “fictional representations of future situations or scenarios” likely to arise. In 2009,
according to the report, influenza will kill 30 million people.
