@AndyBJ Light photons are certainly not atoms, they are particles. One photon does not have any mass at all but a cloud or photons/beam of light have mass because they have energy, kinetic energy and E=mc^2 means energy and mass are interchangable.
@63Hertzi It is not massless, everything that moves/can move has kinetic energy or if its still "potential energy" so rest mass. Most things can move and be still so they have kinetic energy and a rest mass but light can never slow down so it only has kinetic energy which means they also have mass because E=mc^2 which means that energy and mass are interchangable.
Out of curiosity, could there be a star that is "big" enough to have an escape velocity that prevents light from escaping, but "small" enough to not collapse upon itself? I guess this would be the dark star proposed by Laplace.
@TenTonHorse Well its a possibility but if they exist they must be rare because the conditions have to be just right. I believe the star would be very instable. It might be a possible fase for bigger stars before they die.
@Ryalnotch Thanks for your reply. I think I once heard Hawkins in a lecture say that there is a limit to how big a star can be before it inevitably collapses into a black hole (he was probably talking about Schwarzschild's work). I guess a "dark star" would have to be exactly balanced in size between preventing light escaping and collapse.
What I always wondered that if it were true (proven) that black holes can act as a "gate" to another part of space, wouldn't the exit act as a black hole too? And if that's the case then would you be able to even "exit" either black hole since their gravity wouldn't allow you too? Wouldn't you be forever stuck inside that "hole" in space? It seems very mind boggling.
@CyclonedProductions Well some people think that there are so call "white holes". It is said that whatever gets "swallowed" by the black hole is spat out from a white hole. So you wouldn't get stuck in it since the white hole doesn't gravitationally attract other masses.
The thing is that a black hole shreds to atoms anything that gets to its event horizon. An astronaut would be turned into a stream of inward-falling particles--and killed long before by the bath of hard radiation.
this is so fucking interesting--why isn't science taught like this at school? imagine gravity just being 2X as strong, or 5 times as strong, trying to move would be like a marathon...10X--wed all be dead. But then you keep going to 100 times--Then 10,000X and light hasnt even flinched. 1,000,000X and still nothing!--only at BILLIONS of G's is light effected --meanwhile were fucking dead at 10.

@mirabilis Do a bit of research and you can find out that light does indeed have mass. The gist I got out of the few minutes I was digging was that light doesn't have "rest mass," since it's in constant motion, but it does indeed have mass. An experiment could theoretically be conducted in which you take a flashlight and put it in a zero gravity vacuum and find some way to turn it on. The "force" of the initial light emission would push the flashlight back, thus giving light a measurable mass.
@mirabilis As Sagan explained, the essence of General Relativity is that gravity bends space-time. Photons ("particles" of light) travel in a straight line through space, but the presence of gravity bends the space through which the photon is travelling. So it is not directly the photon which is being affected, even though it may appear to be.
@mirabilis The answer is they are not. Einstein proved that it's not light (Photons) that are effected by gravity, but, that it's space/time itself which is effected . This was proven experimentely in 1919 by Arthur Edington from Einsteins special theory of relativity.
I could listen to Carl Sagan talk about anything. He could describe a penny to me for five hours, or how to tie shoe laces and I would still take notes.
@ApostateOfTheDamned There is a large amount of theories in quantum mechanics that have been proven true that also require a 4 dimensional space time universe in fact some require 9 like some types of String Theory.
@yaik7a interesting, but i was more curios of how the forth dimension applies to us and what the dimension is like. (sorry that may question was really general last time, also you seem to know a lot of the subject, yet you don't have to answer my question/s)
4:28 - 4:36 who else thought of symphony of science when hearing this? This guy's pretty special, there's little more I can say about him - whenever I watch him speak about the majesty of the universe and the elegance of its processes, I want to be an astrophysicist.
@maneatingtoilets according to many theories everything bends space-time but suns are so large and heavy that they create gravity, to conclude it's just one way we try to explain gravity
This wormhole-theory is where he derived his physics for the book "Contact" where a single Earth-ship was transported throughout different places in the galaxy to the center, in about an hour, remained there for 2 days, and then ended up exactly where it started and only a short time had passed (20 minutes in the book, a split-second in the movie).
Gravity doesn't affect light, it affects the SPACE through which light travels; if light is completely reversed, then theoretically the hole disappears from the Universe.because the space is completely curved.
@mintez54 so your saying your theory is 100% accurate? u have a dictionary use it,Now u can even make a page on your own defenition of a "theory" and put it on wikipedia, keeps u irrelvent. So your theory is 100%?

@mavs2147 my proposal is also simple the understandings of creation and equality has given the human population Understandings based on "LAWS" that govern not just the land but reality in general , This understanding is born naturual to humans via the fruit of the tree of knowledge of good and bad. If u dont understand the philosophy of love u dont understand god. So move on
@1billion1deaths1 Via the fruit of the tree of knowledge of good and bad? It's fucking ridiculous arguing with a creationist. When someone is so backward, it's like talking to a brick wall. You might as well believe the sun revolves around us.
@mavs2147 No I'm not crazy. I'm saying you should not disrespect the Germans for sympathizing with the nazis in the 30s', it could've happened to any people and the prevailing sociological circumstances allowed it to happen. An entire population can't be evil, and I'm sure you wouldn't say that about the Germans today. The same way you can't say all religious people are to be disrespected, especially as most of them are probably just as peaceful as you are.
@ohedd I give people the general respect they deserve. I just don't feel that I have to respect their beliefs. I generally respect religious people, especially if they're good people, but that doesn't mean I respect what they believe.
@mavs2147 Ok, then let me rephrase; Do you respect the fact that they believe? There will always be different theories- religious, scientific, political, or whatever. The least we can do is to respect the fact that it has great importance to people. I'm definately not saying we should all agree, just not look for differences and get hostile about it. I know it's hard for me to respect gender studies. I think it's like the dumbest shit ever, but I don't want to make enemies with them.
@mavs2147 its even more ridiculous when your understanding for philosophy is pertty lame. Try understanding basic philosophy befor u try talking to me u retart descendent.
@mavs2147 Id bet you'd like to know, Your understanding for basic philosophy is lame because u dont accept the belief and understanding of good and bad. No god=No creation=NO equality=No love=No purpose ...christianity claims moral truth!!!! Good and bad!! This is found through the philosophy of equality and the understanding of whats good and bad. So if u believe in morality u believe in god,,and if u believe in "equality" u must believe in creation.Philosophy is wat seperates us from the rest
@1billion1deaths1 Equality as in "everybody is equal"? That's something we have instilled in this society. In other societies, women are still the lower class. It used to be that same way for every minority, even here.
@mavs2147 Yes but its the belief that every man and women is equal that finds love. And with that belief comes great understanding ,, realization that you and me and every human bein have the same capacity. Realizing this brings "LAWS" of "equality" that were found through philosophy "human higher understandings".
@shockoflogic wats so funny..have u come to high understandings??? will u prosper correctly like a healthy fruit bearing tree or will u die out like a weak tree. If u follow laws that come from "idea" that are define by "belief" and high understanding of the tree of knowledge of good and bad. Or are u a Animal ..with no purpose? If so survive to fit..dont cowar under religiouis beliefs of morality.
@smokemylungsblak wat your a fuking retart..your god understanding is nowhere to be found..stick to animal rights...survive to fit...stop being a fat pussy relying on rules and laws created by religioun/belief/philosophy. Stick to your caveman tacktics kid
@mintez54 theorys is no were near a "fact" can u grasp on that?? if your assumption based on billions of years ago were 100% accurate ther would be nothing to debate about, but seeing as its not. All u christian?? LOL your a self proclaimed christian, just like im a self proclaimed power ranger u dont impress anyone. Obvouisly u got no christian values, seeing as u attacked me and put your god and modern knowledge in two diffrent sections, watta a Joke!!
Its a very nice fantasy to think that you have some time portals inside black holes, and while its not entirely impossible - its a little too far reached to be considered seriously...
I doubt we will crack such mysteries in our life time, too bad :(
Black Holios LOL as believable as bevis and butthead just more quackademic hollywood crap from the degenerate minds who control the media and academia.
I have a couple of questions. First, does this mean that gravity in the 3rd dimension bends space into a fourth? And, since time is part of the continuum itself, does it mean gravity bends that too?
@Voiderify Yes, that is in fact, the case. Both space and time are bent, for example, close to a black hole. Interestingly, time becomes so bent or "compressed" near the event-horizon of a black hole, that if a traveler fell in, he and his craft would experience the end quickly. (CONT.)
@Voiderify (CONT.) But if we were able to somehow view him with a high-power telescope, his trip towards the event horizon would seem to become slower and slower. Eventually slowing to a near stop. It would seem to take hundreds or thousands of years for him to fall in from our perspective. Where from his perspective, it would be mere minutes. This is analogous to what happens near the speed of light. The closer you get to the speed of light, the more time compresses.
Anybody can use their brain as much as Carl does, they're just too into a pleasureable life. I think thinking as advanced as I possibly CAN think is pleasureable.
@JohnF30Music I think that light is also matter...apart from 1 of 4 of the greatest forces, gravity is always stronger, even stronger than empty space itself.
@JohnF30Music Theoretically, light has weight. But only when moving - if you were to stop a photon, it would completely convert into energy and the photon is gone.
@JohnF30Music It's not so much that gravity bends light but that mass curves space so that the light is forced to follow a curved path as it approaches massive objects.
@KayBeeEee1983 It's not being "pulled" through spacetime. It's distorting it. The spatial distortion just happens to look the way this analogous distortion looks, specifically because both are proportional to energy and size. Energy is really what distorts spacetime, and anything with energy does so. If you had a box filled with nothing but light, it would weigh more (distort spacetime more) than a box with vacuum inside. To understand how, we need General Relativity.
@goodnightsty I understand the distortion, I just don't understand how the distortion causes the "attraction" of gravity. In the analogy, it's 3D gravity distorting a 2D plane. Take away the 3D gravity, and the balls wouldn't distort the plane anymore.
@KayBeeEee1983 Ah, okay. The reason the distortion causes "attraction" is actually simple. Nature minimizes what is called the Action, which means that when objects go between points, they do so in the shortest distance. For flat space, this is a straight line. In curved space, it is ALSO a straight line if you are in the curved frame. But if you view it from our frame (which appears flat), it LOOKS curved. So really, all objects are just following the curves of spacetime. Look up geodesics.
@goodnightsty The graph paper demonstration makes it look like a mass STRETCHES spacetime, but if I understand you correctly, it actually condenses spacetime. Is that right?
@KayBeeEee1983 That's the problem with this analogy,on the 2D surface it's gravity (i.e. the weight of the masses ) which create the "puckers". It's like using gravity to explain gravity....it doesn't really work.
too much speculation for a scientist. if a video was little longer he would say the Virigin Mary might have entered heaven alive through a black hole:)
@MrJudube Speculation is good for the brain, as long as you keep it theoretical instead of claiming it as fact. It keeps your mind active and creative. Einstein said imagination is more important than knowledge.
@AndyBJ Light photons are certainly not atoms, they are particles. One photon does not have any mass at all but a cloud or photons/beam of light have mass because they have energy, kinetic energy and E=mc^2 means energy and mass are interchangable.

@mavs2147 No I'm not crazy. I'm saying you should not disrespect the Germans for sympathizing with the nazis in the 30s', it could've happened to any people and the prevailing sociological circumstances allowed it to happen. An entire population can't be evil, and I'm sure you wouldn't say that about the Germans today. The same way you can't say all religious people are to be disrespected, especially as most of them are probably just as peaceful as you are.

@ohedd I give people the general respect they deserve. I just don't feel that I have to respect their beliefs. I generally respect religious people, especially if they're good people, but that doesn't mean I respect what they believe.
mavs2147 2 months ago
@mavs2147 Ok, then let me rephrase; Do you respect the fact that they believe? There will always be different theories- religious, scientific, political, or whatever. The least we can do is to respect the fact that it has great importance to people. I'm definately not saying we should all agree, just not look for differences and get hostile about it. I know it's hard for me to respect gender studies. I think it's like the dumbest shit ever, but I don't want to make enemies with them.

@1billion1deaths1 Tell me, how is my understanding of philosophy lame?
mavs2147 2 months ago
@mavs2147 Id bet you'd like to know, Your understanding for basic philosophy is lame because u dont accept the belief and understanding of good and bad. No god=No creation=NO equality=No love=No purpose ...christianity claims moral truth!!!! Good and bad!! This is found through the philosophy of equality and the understanding of whats good and bad. So if u believe in morality u believe in god,,and if u believe in "equality" u must believe in creation.Philosophy is wat seperates us from the rest
1billion1deaths1 2 months ago
@1billion1deaths1 I do accept the belief of good and bad, so the rest of your point is moot.
mavs2147 2 months ago
@mavs2147 Then u accept "beliefs". How do u think "equality" comes about?
1billion1deaths1 2 months ago
@1billion1deaths1 Equality as in "everybody is equal"? That's something we have instilled in this society. In other societies, women are still the lower class. It used to be that same way for every minority, even here.
mavs2147 2 months ago
@mavs2147 Yes but its the belief that every man and women is equal that finds love. And with that belief comes great understanding ,, realization that you and me and every human bein have the same capacity. Realizing this brings "LAWS" of "equality" that were found through philosophy "human higher understandings".

If u follow laws that come from "idea" that are define by "belief" and high understanding of the tree of knowledge of good and bad. Or are u a Animal ..with no purpose? If so survive to fit..dont cowar under religiouis beliefs of morality.

I have a couple of questions. First, does this mean that gravity in the 3rd dimension bends space into a fourth? And, since time is part of the continuum itself, does it mean gravity bends that too?
Voiderify 11 months ago
@Voiderify Yes, that is in fact, the case. Both space and time are bent, for example, close to a black hole. Interestingly, time becomes so bent or "compressed" near the event-horizon of a black hole, that if a traveler fell in, he and his craft would experience the end quickly. (CONT.)
logandarklighter 11 months ago
@Voiderify (CONT.) But if we were able to somehow view him with a high-power telescope, his trip towards the event horizon would seem to become slower and slower. Eventually slowing to a near stop. It would seem to take hundreds or thousands of years for him to fall in from our perspective. Where from his perspective, it would be mere minutes. This is analogous to what happens near the speed of light. The closer you get to the speed of light, the more time compresses.

Anybody can use their brain as much as Carl does, they're just too into a pleasureable life. I think thinking as advanced as I possibly CAN think is pleasureable.

how does gravity affect light? I don't understand. can someone explain why gravity can pull light?

Because light travels on photons. L2Physics.
MechaKip 11 months ago
@JohnF30Music I think that light is also matter...apart from 1 of 4 of the greatest forces, gravity is always stronger, even stronger than empty space itself.
gameill 11 months ago
@JohnF30Music Light is made of pure energy. Einstein found that mass and energy are the same thing, so light is actually mass with a weight.
whoatemyhummus 11 months ago
@JohnF30Music Theoretically, light has weight. But only when moving - if you were to stop a photon, it would completely convert into energy and the photon is gone.
paddymoep 10 months ago
@JohnF30Music It's not so much that gravity bends light but that mass curves space so that the light is forced to follow a curved path as it approaches massive objects.

In the graph paper analogy, what is pulling the balls through the 4th dimension to create the spacetime "puckers" that we feel as gravity?
KayBeeEee1983 1 year ago
@KayBeeEee1983 It's not being "pulled" through spacetime. It's distorting it. The spatial distortion just happens to look the way this analogous distortion looks, specifically because both are proportional to energy and size. Energy is really what distorts spacetime, and anything with energy does so. If you had a box filled with nothing but light, it would weigh more (distort spacetime more) than a box with vacuum inside. To understand how, we need General Relativity.
goodnightsty 1 year ago
@goodnightsty I understand the distortion, I just don't understand how the distortion causes the "attraction" of gravity. In the analogy, it's 3D gravity distorting a 2D plane. Take away the 3D gravity, and the balls wouldn't distort the plane anymore.
KayBeeEee1983 1 year ago
@KayBeeEee1983 Ah, okay. The reason the distortion causes "attraction" is actually simple. Nature minimizes what is called the Action, which means that when objects go between points, they do so in the shortest distance. For flat space, this is a straight line. In curved space, it is ALSO a straight line if you are in the curved frame. But if you view it from our frame (which appears flat), it LOOKS curved. So really, all objects are just following the curves of spacetime. Look up geodesics.

@goodnightsty The graph paper demonstration makes it look like a mass STRETCHES spacetime, but if I understand you correctly, it actually condenses spacetime. Is that right?
KayBeeEee1983 1 year ago
@KayBeeEee1983 That's the problem with this analogy,on the 2D surface it's gravity (i.e. the weight of the masses ) which create the "puckers". It's like using gravity to explain gravity....it doesn't really work.

@MrJudube Speculation is good for the brain, as long as you keep it theoretical instead of claiming it as fact. It keeps your mind active and creative. Einstein said imagination is more important than knowledge.
