How dense do you think interstellar gas and dust is compared to glass? Do you think radio waves behave in the same manner as visible light?

I'm asking for a link. Give me a link to some kind of scientific publication where it was stated that the missing mass was discovered by comparing photographs.
you can find links yourself.your afraid that the dark matter is just nonsense to group think concensus
If y≠y' then does it mean the Lorentz transformation is 'broken'?
Do you agree y≠y'?
hmmm... mostly OK.
We know any particle of mass m cannot hold a constant radial co-ordinate r once r<Rs, it must travel to the singularity at r=0 where its worldine terminates. However r=0 is a non-removal singularity in the Schwarzschild solution. The Schwarzschild metric does not apply at r=0 and I really have no way to determine the size of the event or point at r=0, if indeed that is an event that exists in my universe. Only if you say "stuff it, I'll just put the numbers in anyway" will you be able to argue that the mass all ends up in a region of space with 0 volume.
Maybe a better approach would be for me to ask this...... a black hole has a given mass, we know the size of space it occupies. I am sure it is possible to calculate the following.... given the mass we know for any given black hole and the physical size of the blackhole at what density would that mass need to be to fit inside the physical area?
I mean literally think of it as a sphere of matter condensed no further than it needs to be to fit inside that physical region of space we can observe where a black hole is present.
So from what I can tell from reading about this is that it actually seems to support the possibility that once the black hole does not contain enough mass to maintain the gravity well it's radius would become larger than its Schwarzschild radius and is no longer a black hole as light can then escape.
I found that in fact density is a vital part of calculation for the Schwarzschild radius of a black hole. And in fact that to exist smaller black holes must have an increased density. The increased density ultimately sets the size limit of black holes with smaller sizes based on the particles being squashed more, until we reach the limit of what can be squashed.
So as a black hole gets smaller it must increase in density to maintain the Schwarzchild radius.
The consensus currently is that a black hole can exist with a mass of one gram?
If there is not enough mass to form that geometry then how can it maintain that shape?
do not require mass to exist?
Finally if black holes persist for such a long period of time and only end their lives in a wimpy pop of hawking radiation then we should be observing black holes of all sizes everywhere as they would be the most common cosmological entity.
When the density drops below the point that gravity escape velocity drops below C
Is that correct? Do you agree?
To start, even though we do analysis in the Special Relativity, any time a change of a grid of inertial observers is applied it involves an acceleration.
The simple comment that we are going to say one grid of inertial observers sees/observes something and we would like to say that another grid of inertial observers sees something else, this change of observers has to undergo acceleration analysis.
Well, there are some issues, let's discuss...
this frame is 'preferred' because its time is the shortest.
Given the effects Earth's magnetic field has on people's hearts, what would happen if I rapidly waved a fridge magnet past my heart? Would it disrupt the electrical signals in my heart and cause it to stop?
