​@B4JesusChrist Most people with a penchant for science, realize that gods and devils are delusions, fiction, pure myth. If Jesus actually did exist and was not a fictional character (which is the position I take, as it is the most plausible) then it is quite possible that he was either a lunatic or a liar -- as we see no indication he was Lord, since the Universe did not require an infinite regression of creators creating the universe to bring it into existence. We can not explain EVERYTHING just yet, but we CAN explain enough to know that gods are not required, therefore they are no more than just wishful thinking of the ancients. A simplistic answer at best.

@stevejquest

​@B4JesusChrist The cross or crux is an astrological symbol. Jesus is a sun god, the halo about his head is the rays of the sun. He is the sun (son) of god. For thousands of years, carvings on temples, cave walls, monuments and artifacts have honored the sun, bringer of warmth, security, life and light. The ancient zodiac wheel with its four cardinal points traces the passage of the sun as it moves through each of the 12 constellations marking the four seasons, the spring and autumn equinoxes and the summer and winter solstices. Our ancestors personified the sun, worshiping it as the light of the world, the sun god, the savior of mankind. It is no coincidence that our principal day of worship is called Sun Day. The Bible tells us that three wise men came from the east, following a star that led them to Bethlehem to celebrate the birth of Jesus the Messiah. Joseph claims that the star in the east was Sirius, the brightest star in the sky, which on December 24th aligns with the three brightest stars in the constellation of Orion (Orion’s belt). The stars were referred to by many ancient cultures as the Three Kings. And when Sirius (the brightest star) lined up with the Three Kings, they pointed to the place of sunrise on December 25th - the symbolic birth place of the sun or son. So why December 25th? As the days grow shorter in the period leading up to the winter solstice, the sun appears to stop moving south and stay still for three days - the 22nd, 23rd and 24th December in the northern hemisphere. This is the meaning of the word ‘sol-stice’ - sun standing still. To our ancestors this period symbolized the death of the sun god (son of god) and when three days later on the 25th December the sun started moving again, the sun was reborn - hence the birth of Jesus at this time - the sun god or son of god. During this three day period, the sun resides in the vicinity of the Southern Cross constellation and appears to ‘hang’ on the cross, hence the story of the crucifixion. However the resurrection of the sun or son is celebrated three months later at the spring equinox (Easter) when once again the forces of light defeat the forces of darkness and the days grow longer than the nights. And why was Jesus born in Bethlehem of the Virgin Mary? The Virgin Mary is the personification of the constellation Virgo - Virgo has represented the great female deities (the Goddess) since time immemorial. The Divine Mother and her Consort/Savior Son is a strong theme in goddess mythology, making the Virgin Mary/Mary Magdalene a likely composite. The name "Mary" is etymologically related to water, the element of birth and the astrological glyph for Virgo is an ‘M’. The Virgo portion of the heavens was known as the House of Bread because the Sun is in the house of Virgo in August-September - harvest time in the northern hemisphere. Virgo is usually depicted as a woman holding a sheaf of wheat like the great goddess Demeter/Ceres. The words ‘bet lehem’ (Bethlehem) in Hebrew translate into House of Bread. So on the night of the 24th December, Virgo the great maiden/mother of Bethlehem rises in the northern hemisphere night sky from 10 pm to dawn, heralding the birth of the new-born sun, three days after the winter solstice. I hope that helps clear up the confusion.

If god created the universe, then someone had to create god, create god's creator, create god's creator's creator and on into infinity. I am an atheist EXPRESSLY because I have read and studied the bible. Had I never read the bible, I likely would have believed in it. But the contradictory nature of the bible and many inaccuracies (such as the earth being flat, having four corners and describing earthquakes as God shaking the wickedness off the earth) was just false. If so much of the bible is demonstrably false, I extrapolate ALL of it is false. Atheism doesn't provide any delusional rewards so I am actually stronger than you, psychologically.

If the universe is expanding no matter what at the speed of light or faster, it means that there is nothing outside of it, not even darkness. Darkness is probably lack of light and no physical substance in itself like light. The question still remains, what is there beyond the expansion frontline? If the universe is expanding in some kind of a space that can be prefigured, it means that there is some kind of a space where the universe is expanding. I think the cosmologists will never find an explanation on this issue and it remains more or less a matter of belief or hermeneutic reasoning.

I figured this out on my own long ago. But he is wrong about one thing: "space" is NOT expanding. The only thing that is expanding is the amount of space occupied by galaxies which we can see: these galaxies are moving into space, but "unoccupied" (as far as we know) space. What he has failed to explain is if galaxies in every direction are moving away from us (presumably in speeds related to a constant dependent upon the galaxy's distance from us). If this is the theory, it sounds rather "Milky Way centric" to me. Also, the Big Bang Theory would seem to be disproven by this presumed fact. Why are some galaxies closer to us than others? Are some coming towards us? Stuff to keep you awake at night.

@caccioman

TheGreatToucan if you Look at the balloon (Imagine the balloon as perfectly round sphere) every point on its surface is the center with regard to all other points, no matter where it is. So we are also moving away faster than the speed of light from all points further than 14 billion light years. Nothing milky way centric at all. Also only Space itself is expanding: the Surface of the balloon (=Space) keeps getting larger and larger. Its not that the Galaxys are expanding into empty Space which has been there before. In the beginning everything was in a Single Point (big bang). Just the Expansion of the Universe and space made it possible that things as eg Particle and matter which later would form galaxies could exist separately from each other. If you cover a very tin y deflated balloon completely in paint and it starts inflating, sooner or later little stretches will show which the paint in the beginning couldnt cover. If you keep on inflating (much larger as possible with a real balloon) the stretches not covered in paint will become much larger in relation to the Spots with paint. Keep in mind: even as the balloon stretches infinitely, the amount of paint from the beginning stays the same. So the paint finally rests just in little Spots (galaxies) while the balloon (Space) keeps on inflating. Thats at least how i understand it

You can only travel faster than light if it is travelling through some medium that slows it down. In the vacuum of space light travels at its greatest speed and nothing can travel faster.

@Stable Genius Absolutely not. Our ability to measure the speed of light has nothing to do with the operation of the Universe no matter how arrogant we are in assuming it is so. Bodies with mass can never travel at or faster than the speed of light, it is fact supported by thousands of experiments, just accept it. If you have an open mind and are wiling to take the time to read a simple explanation that does not involve time dilation, length contraction, increasing mass, or any other exotic concept, of why this is true, I will gladly post it here for you. Just say the word.

My understanding is that if you measure it a second time (or third, etc) the result will be the same as the first measurement, which implies its state does NOT revert between measurements to a superposition of Up and Down spins.

Very well explained. Super interesting!!! 😊

Sure... We're still far away from accelerating any macroscopic object close to light speed. But that's ok, because we have got technical challenges to overcome while still remaining within the bounds of possible. FTL travel may turn out to be totally impossible, like in cellular automata such as Conway's Game of Life.

Subscribed, this is really fascinating

If you have to measure to know which of the two entangled particles has the + spin and which has the -, you have to measure it to know which is which, how can you know that the entanglement didn't sync the particles instead? I'll be really impressed when we can actually "measure" superposition. If instead the entangled particles "superposition" is them being in sync with each other, then that FTL information transmission vanishes, I would think. But without being able to "see" superposition and know for sure it is happening, even if only indicated indirectly, then we cannot say for sure that they were +/- instead of being in sync with one already a + and the other a -. Not quiet the same thing to my mind, but maybe that is just me.

'how can you know that the entanglement didn't sync the particles instead?' Bells inequality. Its a bit tricky to explain in a satisfying way, you might want to check out some videos on that term as its surprisingly tricky to really grasp, but if the particles were somehow preset (Which is called a hidden variable hypothesis.) then they should have a different rate of correlation in a Bell test to if they were not preset. The experiments always find that they trend toward not being preset. Its a little like ignoring the results that are directly entangled for a moment and just looking at what happens when you just prod at what the state of the particles are in. If they are preset youd expect a nice linear correlation between the results trending up to a clear 1 on one side means 0 on the other, but thats not what you get in reality. This doesnt entirely rule out hidden variables for a few reasons, but theyve kept searching with increasingly excessive experiments for any way that hidden variables can still remain, so far nothing turns up.

@Hank254

Look up Bell's inequalities. The current interpretation of experiments is that the entangled particles don't have a specific spin until one of them is measured. When one is measured, the other instantly obtains the opposite spin. This is an old but very good documentary that explains it fairly well: kzread.info/dash/bejne/dHqqrLGTZZTancY.html

You suppose the entangled particles are already determined when still together, but it's been proved to be false. (Bell's inequality, if you want to look it up). (ok, not if hidden variables are non local).

@iamamcnea

The example in the video wasn't the greatest because as you said they could just be "in sync" and if that's the case no FTL information is needed. However, there are experiments in which the outcome of entangled particles can not be determined by the particles being in sync. This is basically the Bell Inequality, which mean No Hidden Information in a classical system (i.e. being in sync) can explain the experimental outcomes. Here is a good video on it: kzread.info/dash/bejne/jKmqrY-olJmaZ8Y.html

The last case you mentioned here sir proves that we already are moving at speed faster than light. Since the object far away from us is moving away from us at speed faster than light. That being said it is never said that we are the center of universe and we hold our position in the universe very statically. Hence we are also at a place that is traveling away from a distant place in universe at speed faster than light.

I like how you explain how the universe is not expanding but slowing down . light is faster than causality that's why we can't go that fast but how much faster is the real question .

For exploration purposes, it could be more advantageous to travel near the speed of light, utilizing time dilation to travel to the edges of the universe in a lifetime.

I know I am late and this explanation is oversimplifying a really complicated phenomenon, however I’ll give it a shot anyway. Particle entanglement is a somewhat nebulous concept that isn’t verry well understood. Basically it happens when a particle interacts with another particle. Imagine two electrons crashing into each other. Before that we could know (for example) the position of one particle at a time. Afterwards we can calculate the position of the one particle by looking at the other. This is not really how it works, however it both isn’t verry well explained and I personally don’t quite understand it, so this approximation will have to do. Now you might also see how the information is supposedly traveling faster than light. If we ensure two electrons interact in a way, in which they need to have opposite spins, without knowing which spins these are, then we can know the spin of one by looking at the other. So if we take the two electrons a long distance apart without knowing which has which spin, we can look at one of them and immediately know the spin of the other. Therefor the information of what spin the other electron has to have must be traveling faster than the speed of light. As said I myself don’t quite understand this topic and have also left out a lot (such as the concept of quantum superposition), so if you are trying to learn more I highly recommend looking the topic up yourself, however I still hope this comment could help gain some insight into the topic. P.S. It is entirely possible my explanation is simply wrong so take everything said in this comment with a grain of salt.

@@mr.winter538 it sounds right man, but I don’t know really. The way you put it though disappoints me, I’m sorry to say, in that, I can’t think of a “workaround”, can’t even imagine how we could *exploit quantum entanglement for the purposes of us physically traveling*. The more I read about these things the more defeated I feel, in that we won’t find some kind of key to u locking some untapped potential to do some craaazy stuff. I was hoping that after James Webb telescope launch on 12/18/21, six months of setup, and like a year, we would make a groundbreaking discovery, the information key to unlocking an ability to exploit a phenomenon we find, and using it for cool stuff. Bah.. Well we might well find a planet along the way, while looking back at the Big Bang, that has such similar markers as ours in its atmosphere, that the potential for at least some form of life is highly probable, or hell maybe we see smog from burning fissile fuels, wouldn’t that be crazy!? I imagine we could also learn some relatively disappointing things, like for instance nothing on any planet ever. Totally possible. So you’ve blown a bit of my flame down, but it’s not out. Don’t feel bad, as much as I like to wonder about ‘impossible’ things, equally I would like to know how probable they are, like any amount greater than 0 would be cool.
