Dive deep into the secrets of the cosmos with renowned astrophysicist Neil deGrasse Tyson as we explore the enigma of the universe's age. Is it possible that everything we've come to understand about the universe's timeline might only be half of the story? Join us as we traverse groundbreaking new research suggesting the universe might be a staggering 26.7 billion years old, not 13.8 billion as previously believed.
In this insightful video, Tyson reminds us of the scientific process's rigor, emphasizing that new theories must endure rigorous testing before being accepted. From black hole singularities to cosmic inflation, each concept is explored, offering a comprehensive understanding of our current knowledge and where it could be headed.
With the wisdom of Einstein's general relativity, and fascinating insights into the cosmic inflation theory, the narrative extends beyond the standard Big Bang timeline. We also delve into the debate sparked by inflation theory, the mysteries of early galaxies, and what advanced technology like NASA's James Webb Space Telescope might reveal about our universe.
While the universe's timeline may be a matter of speculation and investigation, Tyson emphasizes the compelling evidence that points to our current understanding of the universe's age. Yet, in science, no idea remains unchallenged, and the quest for knowledge continues, powered by an enduring spirit of curiosity. Tune in to witness an intriguing journey that challenges our conception of time, the universe, and the mysteries that remain to be unveiled.

Awesome video ! I love it so much . Thank you for sharing . When you know about the universe , you know also about the habitable planets existing in it , and the origin of aliens lives , and the humen beings , animals etc. living on earth . Happy week-end to you !
It may be much older, however, our Perceptions in 3 dimensions could be different. Even our instrumentations may have to be adjusted to measure distances at a different frequency.
The speed of light, gravity, electricity and charge are generally considered to have basic elementary values that are universal and constant in time. If one opens up the possibility that they may vary in time, one also opens the possibility that they are not universal, unless there were some underlying mechanisms that controlled their temporal variations, thus keeping them spatially universal. I would think that such mechanisms are beyond what the proponents of variable speed of light et cetera have considered.

Gravity varies time
Try looking at bubble mechanics as a proxy to understand a multiverse. A multiverse with infinite bubble universes. Some popping into and out of existence. A bubble that is near another bubble, when it pops, sometimes it's contents enter a nearby bubble making it larger. You can hear the fizzle of bubbles popping. If you had a sensitive enough detector on 1 bubble you would be able to hear or feel a distant bubble popping. I believe this fizzle, if there is a multiverse, will be detectable engrained in gravitational waves.

The most distan galaxies are more bigger in terms of angular diameter than the other ones more closer to the Milky Way, according to Webb telescope data, too many explanations about that but actually nobody knows what really cause that effect
I have a dumb question. Why can't the new galaxies that have been seen actually be moving in the opposite direction. I mean when you blow something up on the ground it goes up 1 something blows up in space it goes in every direction.

I don't think of expansion slowing light or light losing energy over time. I think of all the photons from other stars interfering with that photon from the star we are studying and realizing the farther it travelled, the more interference it encountered. So called light filaments might be clusters of light diffusion from interference patterns due to local galaxies with more light. It is possible there is an upper limit a photon can travel before being fully attenuated by the light of other stars. This means you can have a static, nonexpanding universe and stars farther away have much more light attenuation in terms of phase. Furthermore if you aim a telescope at a star and study the light in that direction does not prove that the light you obtained comes from that star and not other stars near it you cannot see or other stars out of the direction of view, reflected or refracted into your direction of view.

@@CarlynLei If space has local densification, then it probably has reflection and refraction behaviors of incident light upon it, and our socalled map of the universe is the result of all those distortions but the stars are actually in very different places. Then all of a sudden you can look at galaxies as local densification lensing of stars as though they are concentrated in a place when they actually aren't and the galaxies are not real, that is their structure is actually the densification layout, not star layout.
Nothing to do with this video but I have a thought . If a Star is in fact heavy enough to bend space , and a black hole likewise is so heavy light can't escape. What way is space bending in. Because if it does weigh enough to bend the fabric of space, this means that there is a top and bottom of space like there is gravity in the universe so there is an up and down.

@@timmy-wj2hc all I'm asking is any objects with extreme amounts of mass bend the space around them. Like a black hole . So if it is bent like the ball on the piece of fabric then what is causing it to bend a certain way/direction. Is there something pulling it down like we are in space but there is a gravity source pulling it in a certain direction ⬇️ ? No matter what we see from any angle it should always look the same . But if we observe a black hole from different angles the blah hole always seems to have a part that seems like the down side . As with the few pics of the black hole that took .

That apparent up/down is kind of a visual trick, partly because of the accretion disk around the black hole (and sometimes the relativistic jets,) but mostly because that's how humans are used to seeing things. A large mass warps space from all directions towards the center of the mass. So, visualize the "heavy weight on a sheet of rubber," but twisted in a million different directions and superimposed on itself.

Okay that's a line of thought. I way I like to think of a conscious universe is in terms of life. Not that the universe is living or that it has souls or qualities; qualities because in Hindu philosophy matter is believed to possess three qualities - goodness, passion, and darkness, that is the sattva, raja, and tama gunas (as per wikipedia). But a different translation of the gunas can also be virtue, action, and inaction. I do not want discuss upon the merits of such philosophy for I am no philosopher. But I have a degree in Physics so I essentially see the world on the basis of physical theories. Sorry for making this a long comment. As I was saying, my views of a conscious universe rests upon the presence of life. If life is universal, if conscious, thinking, sentient beings exist in places other than earth, proliferating across distant galaxies, then the universe can be deemed conscious through life. Since we are made of the same atoms as stars or planets, so through us, the universe experiences itself. Here's an article about panpsychism www.scientificamerican.com/article/does-consciousness-pervade-the-universe/#:~:text=According%20to%20panpsychism%2C%20consciousness%20pervades,that%20literally%20everything%20is%20conscious. @@noself7889
In other words *the Big Bang is not falsifiable!* Then what about this: *BIG BANG* Falsified by Gravity: 1. Big Bang assumes energy and matter from nothing in a quantum singularity or fluctuation 2. The density is quoted variously as extreme to infinite 3. The total mass of the universe curves space and shapes the universes destiny 4. Black Holes have an escape velocity at their event horizon equal to the speed of light 5. The size of a Black Hole is measured by its mass which gives the diameter of the event horizon 6. The mass of the universe is ~1e80 protons = 6.7e53 Kg 7. The formula for escape velocity = (2GM/r)^0.5 Therefore r = 2GM/v^2 8. Given M = 6.7e53 Kg and v = 3e8 m/sec therefore Dia = 2.r = 52.5 billion light yrs 9. The universe cannot at any time have been smaller than 52.5 billion light yrs in diameter 10. This is called the Schwarzschild's Radius of any mass and is well known 11. Adding Dark Matter to this only compounds the problem so is also falsified 12. Hence the matter in the universe can only have been created *after the expansion of space..* 13. The separation of space and mass is unique to the Genesis account of creation! *The Big Bang is falsified as a violation of the law of gravity! Q.E.D.*
