The problem is that the big bang is just speculation. The reality is that we cannot even speculate our own existence. Waiting for theory that 'just works'.

You won't believe me when I say, but there are a lot of lies in the science world. The LHC is secretly an underground satan1c ch1ld sacr1f1cing operation tied to the vat ican and 1llum1nat1. The diagram and explanation of it is abstract gibber for ch1ld s3x. Alice is really a young girl. This is why it is made of a large ring and small ring. Alice gets covered in "gel" during the particle "smashing" event. They're speaking about orga5m and ej@culation. Read it in wikipedia and think about what I am telling you. The very name Alice has always been connected with it since the story Alice in wonderland. Everything science tells you about the universe is wrong. Tesla was more right, but not completely understood. To understand the universe, we have to look without the ideas of science tainting our thoughts. Einstein explaining big bang was just rewording genesis and acting like he is God. Whatever subject you try and explain the universe with, ultimately limits it's true expression as the universe. There are realms. Reich means realm. If the stars were where you think they are, then you'd see them during an eclipse. How does a crescent moon and star appear if the moon was closest to earth and orbiting? If you can see the moon in full daylight, then how does the sun hide the stars? Take a good look.

So how far was the decimal place carried out in the equations 10`50 place would be impossible to compute but still would be a tremendous error in calculating the vastness of the universe, I'm still not convinced "dark matter" and "dark energy" exist outside of compounded computational errors.

Well. I would hold back the congratulations. Scientists really like to be able to write their papers and that means confirmation bias. Just consider the papers blocking epoch-dependent G Models (where G is Newton's Gravitational Constant). The confirmation bias is so ludicrous that the reason why the paper should had not been published is right on the Abstract..:) arxiv.org/pdf/1402.1534.pdf "An important caveat is that it rests on the assumption that the same mass of 56Ni is burned to create the standard candle regardless of redshift." These people used L-CDM to "test" epoch-dependent G without changing the Chandrasekhar Masses of the White Dwarf Supernovae Precursors. No wonder they couldn't find any G dependence. The same goes for the Lunar Ranging Article. The predicted epoch-dependent G rate of recession of the Moon is smaller than the observed, which allows for extra sources of Moon orbit modulations (tidal locking, etc). I also demonstrated the there is no need for Dark Matter in any astronomical observation: www.quora.com/What-is-the-status-as-of-2019-of-the-search-for-dark-matter/answer/Marco-Pereira-1 and that the Universe does not follow Einstein's equations and thus GR , L-CDM is wrong. www.quora.com/How-would-anyone-defend-general-relativity-from-Marco-Pereiras-HU-challenge/answer/Marco-Pereira-1 So, the extra baryonic matter just adds to 100% of what is supposed to be out there. I would welcome our nice scientist to engage with me here or through email. I want to get to the bottom of this and understand why scientists cannot take a No for an answer (confirmation bias or pigheadedness)

With that being said I am only encouraging you to say what you mean. There doesn't have to be a war. I respect people who don't beleive in God 100% as long as they admit they don't know for sure and its possible God exists. Us believers will always beleive but as men and women of God we should be embarrassed at the lack of attention and respect and gratitude we give to the hard working, educated and seasoned people who make discoveries, images and videos like these possible. Thank you sir but proving the original hypothesis to be correct is awesome and does validate your work even more but nothing ever will or ever can awaken close minded, selfish, materialistic people to change. They choose like all mankind does. But putting that self righteous spin on the closing comments did more damage than u may think. Stay positive. Negativity and hatred are for lames and I don't take you to be a lame dude. I think regardless of followers which I don't care about because I never have had social media you would earn more respect and attention if you were to say what you really mean instead of being on the fence but with both feet leaning a certain way as is obvious. You could check me and shut me down if I missed something and I will apologize if necessary but I think you should respond to this or just get lost in the crowd of cool guys who think they are always right or wait u r a science person so u are excited to be wrong. Right? Its exciting to think a being such as God could exist if you aren't in support of that right? Also people who don't like science stuff incorporate science in their lives all the time whether they are aware or not, same as math. So 'non science' people are -------------- ? Just saying man, u post, u r accountable. I pray you have continued success and peace and joy in your life and I didn't mean to come hard at you,, but I grew up tough and I'm rough around the edges and you probably needed to hear this because I never post like this let alone something this long to start my day but God aka my conscience aka my heart aka thoughtfulness of the feelings of others led me to comment because I am passionate about how people treat and love others and I am strong but weaker people may have been offended and hurt rather than inspired and amazed. That is on them to feel that way but you could have left that comment of division out and just praised the scientific community on being right without putting anyone down. But hey you got it now! Every piece of matter that ever existed fully accounted for! We are clueless to whats really what, the age of anything period, and the truth behind all the ancient civilizatiozns and their understanding of the cosmos which appears were at the least comprised of giants with technology beyond ours most evident in the cutting and moving of huge stones. We don't have all the answers and never will but let's keep encouraging one another to keep going farther and to dig deeper every day. Thanks! God Bless or good luck to all!

From my own experience, learning to recite a whole two millennia of evolved educational narratives, the theoretical made historical, ie assumptions of political reality, ..as if it were real-time absolute textbook knowledge, ..is next to impossible to correct and rethink yourself from first principles reasoning, ..as we are supposed to do(?), but are actually discouraged from doing by tribal "code of silence", hierarchical dominance behaviours. (Eg Forget this if you haven't noticed, Upton Sinclair's coding) The Youngs Double Slit Experiment results are enough on their own to discourage reciting Big Bang dogma. So the apparent proximity, density and intensity of emissions and reception of communication information is simultaneously simpler and more complex to interpret in real-time Mathematical logarithmic time coordinate Actuality. If you know about the trick of using using FM high frequency beams of light or sound to project an interference positioning source of EM or sound, no further explanation is required, only practical application analysis as it is in Actuality. "Objectification" is not actually commonsensical and coordinated, not methodological Sciencing, it's "Science" the literal word, and corrupted by "senseless" debatable tribal politics. (All true to our nature of course)

Oddly tho the billions of years since the big bang is nothing more then earth years .. on a cosmic scale being that everything is moving close to the speed of light if not the speed of light the time frame in which everything has happened on a cosmic scale is only happened within a month comparatively to the time on Earth. For those that are probably wondering what the hell are you talkin about time dilation.

Genesis 1 In the beginning God created the heavens and the earth. 2 The earth was formless and empty, and darkness covered the deep waters. And the Spirit of God was hovering over the surface of the waters. 3 Then God said, “Let there be light,” and there was light. 4 And God saw that the light was good. Then he separated the light from the darkness. 5 God called the light “day” and the darkness “night.” And evening passed and morning came, marking the first day. 6 Then God said, “Let there be a space between the waters, to separate the waters of the heavens from the waters of the earth.” 7 And that is what happened. God made this space to separate the waters of the earth from the waters of the heavens. 8 God called the space “sky.” And evening passed and morning came, marking the second day. 9 Then God said, “Let the waters beneath the sky flow together into one place, so dry ground may appear.” And that is what happened. 10 God called the dry ground “land” and the waters “seas.” And God saw that it was good. 11 Then God said, “Let the land sprout with vegetation-every sort of seed-bearing plant, and trees that grow seed-bearing fruit. These seeds will then produce the kinds of plants and trees from which they came.” And that is what happened. 12 The land produced vegetation-all sorts of seed-bearing plants, and trees with seed-bearing fruit. Their seeds produced plants and trees of the same kind. And God saw that it was good. 13 And evening passed and morning came, marking the third day. 14 Then God said, “Let lights appear in the sky to separate the day from the night. Let them be signs to mark the seasons, days, and years. 15 Let these lights in the sky shine down on the earth.” And that is what happened. 16 God made two great lights-the larger one to govern the day, and the smaller one to govern the night. He also made the stars. 17 God set these lights in the sky to light the earth, 18 to govern the day and night, and to separate the light from the darkness. And God saw that it was good. 19 And evening passed and morning came, marking the fourth day. 20 Then God said, “Let the waters swarm with fish and other life. Let the skies be filled with birds of every kind.” 21 So God created great sea creatures and every living thing that scurries and swarms in the water, and every sort of bird-each producing offspring of the same kind. And God saw that it was good. 22 Then God blessed them, saying, “Be fruitful and multiply. Let the fish fill the seas, and let the birds multiply on the earth.” 23 And evening passed and morning came, marking the fifth day. 24 Then God said, “Let the earth produce every sort of animal, each producing offspring of the same kind-livestock, small animals that scurry along the ground, and wild animals.” And that is what happened. 25 God made all sorts of wild animals, livestock, and small animals, each able to produce offspring of the same kind. And God saw that it was good. 26 Then God said, “Let us make human beings in our image, to be like us. They will reign over the fish in the sea, the birds in the sky, the livestock, all the wild animals on the earth, and the small animals that scurry along the ground.” 27 So God created human beings in his own image. In the image of God he created them; male and female he created them. 28 Then God blessed them and said, “Be fruitful and multiply. Fill the earth and govern it. Reign over the fish in the sea, the birds in the sky, and all the animals that scurry along the ground.” 29 Then God said, “Look! I have given you every seed-bearing plant throughout the earth and all the fruit trees for your food. 30 And I have given every green plant as food for all the wild animals, the birds in the sky, and the small animals that scurry along the ground-everything that has life.” And that is what happened. 31 Then God looked over all he had made, and he saw that it was very good! And evening passed and morning came, marking the sixth day.

Serendipity! I just watched Emily Levesque's talk on stories from observational astronomy, and she talked about how the fast radio bursts were originally ignored as "local noise" and that by doing the work to isolate the origins of the noise-people opening the microwaved or in the lunch room before the timer shut the microwave generator off-they found one burst which wasn't a microwave door being opened.

Please, someone, correct me if I'm wrong but at 5:00-6:05 he talks about how the light detected from a distant quasar is redshifted the farther it travels. He furthers this point by talking about the Ultraviolet spike from the Lyman-alpha transition being yellow light by the time it reaches us. He then mentions the absorbed dips in the spectrum as hydrogen absorbs this energy along the path from the quasar to us. What confuses me is the next part where he says that the hydrogens closer to US will absorb shorter and shorter wavelengths. Shouldn't it be that the hydrogens closer to the quasar should be absorbing shorter wavelengths as the photons had less time to red-shift? The diagram also confuses me as at 5:18 it shows the light leaving the quasar to be ultraviolet and red-shifting into yellow light, but then at 5:58 it shows the light leaving the quasar to be yellow and then shifting into UV light by the time it gets to us.

What's interesting to me is that scientists are obsessed with the 5% baryonic matter (yes, we are made of this matter and we know how to study it) while largely ignoring dark matter and energy. Shouldn't we be thinking of ways to study dark matter and energy? Isn't there likely to be a huge payoff from that? It could easily redefine how we view reality.

Uneducated Question #1: If 50% of Matter as we know is dispersed, does it mean we can Use it? Like, Collect it? I'm thinking on 'collecting matter to use as fuel in space travel' Uneducated Question #2: If we eve try to do some space travel...wound't we hit those?! like pebbles?! Doesn't that makes the idea of interstellar travel more dangerous?!
