Neil deGrasse Tyson: 'Dark Matter Doesn't Exist And Didn't Come From Big Bang'

When we talk about dark matter and dark energy, there's a lot we don't know compared to what we do know. What we do know is that there's some strange force that brings galaxies closer and keeps them together. At the same time, dark energy is making the universe expand faster. But we haven't found these mysterious particles yet.

I am also sorry, sorry I allowed myself to let a headline draw me in to a video that as nicely put together as it is, has no new information and no apology from Neil DeGrasse Tyson for misleading the world about dark matter or dark energy, only his concern that the naming of the phenomena might have been better. That’s not new, just his opinion and while I agree with the opinion, it’s not an apology for anything.

I find it amusing how seriously proponents of these mythical phenomena take themselves, while simultaneously admitting that no one knows what dark matter and energy actually are. We may as well call them Black Magic and Pixie Dust.

We just cannot underestimate the gravity of this situation! 👩‍🚀🪐🔭👽

Dark Matter. The modern equivalent of "Here be Dragons"

[mickking]

Scientists are always 'right' until another scientist says they're 'wrong'.

[aaronmurgatroyd]

Missing Mass is a much better name for it than Dark Matter, as it describes our current knowledge of it, maybe Missing Gravity…

[tsh]

Anyone who says Dark Matter doesn't exist, hasn't seen my cooking. 😉

There is no need for a singularity and a "Big Bang" for the universe to exist and exhibit all the wonders of reality that we can see and experience. I wish I could show you some graphics, but for now, you will just have to use your imagination to picture this.
Imagine a spherical toroidal shape in otherwise "empty" space with a tiny hole through it. If you google toroidal you can see a good image of one. The hole on one side appears to be a black hole with everything being drawn into it, and on the other side is a white hole from which everything flows out.
All reality that flows out of the white hole circles the circumference of the toroidal shape in all directions like longitudinal lines on a globe to eventually re-enter on the black hole side, only to be compressed and ejected through the white hole again and the process is repeats infinitely.
Our known universe does not include the white or black holes. We are but a mere 14 billion year surface patch on the path along one of the longitudinal lines making the journey around the toroidal shape between the white and black holes, which explains why the universe appears to us to be flat. It also explains why large galaxies exist at the beginning and beyond beyond our known universe as the JWST shows and also works with the Ether. Ether IS the force of gravity!
Our known universe is just one of countless others making the journey out of one side, around and back into the other, again and again and again! The time needed to make the complete trip around the toroidal sphere is likely undefined trillions and trillions of years, but likely could be calculated.
This can all fit nicely with string theory and multi-universe theory and explain why our known universe appears to be the result of a big bang. Newton was right about the cosmic clock, it's just that it has been ticking a lot longer than we think - a "hole" lot longer - pun intended.

I think we need to conclude that space is gravity, and gravity is space. And when mass condenses out of space, gravity gets more tightly wrapped around it.

[robertmuller]

It should simply be called unexplained gravity.

[herbertseufert]

I think Dark Gravity results from the primordial structure of space time which isn't flat in detail and not smooth. Gravity is a deformation of space time and there may be a primary dynamic matrix with elevations and sinks that dominates and rules the arrangements of visible matter. Masses concentrate in depressions below the "average level" and there's a lack of them on elevations. This is the base of the arrangements of galaxies, clusters, superclusters, voids and supervoids.

There's a primary matrix of the stage of space time. Visible matter concentrations enforce the deformations of space time, but they're not the primary elements: they just follow the primary relief of space time like water is sampled in a sink or a valley, not on a mountain!
A ball rolls downhill, not uphill.

Maybe the "strange" bound rotation of galaxies is a lokal rotation of space time like a vortex that passively drags matter with it. In the center a Black Hole like a drain in a bathtub.
I think space time isn't flat, it's not smooth in detail. It's a dynamic uneven matrix and looks like the surface of a battered ball.

For us this looks like the presence of invisible matter.

We must forget the notion that gravity always involves the presence of matter or mass. Primordial, probably even dynamic deformations of the spacetime matrix produce gravitational and time dilation effects that dominate the universe. Dark gravity is primary gravity through primordial warping of spacetime, it is not bound to mass and rules the "geography" of the universe.

[DFC]

To all the Fred’s out there. You have meaning. 💪

[johnhewitt]

If 95 percent of the universe is invisible why should physics (which is based on what we observe) be correct?

[gibbon]

One possibility for the absence of dark matter could be that there's an absence of dark matter?

[jaime]

If dark energy causes a repulsive/inverted gravity instead of attractive gravity, does that mean it could be fueling the expansion/inflation of the universe?

[mitchr]

Funny how all of these theories began to arrive at the same moment in time that Weed came to the Math dept of your local University, lol.

[cosmoslogic]

I just want to make a short statement about the Cosmos we are affected by the smallest items that we can not even see Why is this I will give a few examples the wind, and moisture is hidden in the Air, Quantum is the ability to super fi the computer world I just wanted to point this out, without the smallest world there will be no Huge world to live in. There will be at least a thousand questions that we will never know the answers to

[DiHandley]

Well, there are two things in the universe that are connected but we can’t see. Light and gravity. It’s travelling through the universe. Remember E=MC2. So they are all connected.

[whitehorse]

No worries people’s of planet Earth, because ChatGPT 9 will answer this question of the missing gravity in our observable universe. The answer lies in a 5th dimension of SPACETIME.

If this dark matter barely interacts with the "normal" matter then how it is keeping the galaxies from falling apart and how its causes the universe to expand? Why something needs to keep the galaxies intact when this is the job of the black hole in the center of the galaxy? Isn't the black hole pulling all stars in the galaxy together and into itself? Why we need some external force force do that? If there are many black holes in the universe wandering around, how do we know how many are they, how can we access their gravitational pull?
