@Veritasium, Try if you can make a video on this topic. It will help me to explain to my niece, who one day wants to be an astrophysicist. Since Earth is revolving the sun in an elliptical orbit, also the Sun is not the exact center of that orbit when Earth leaves away from the closest proximity of the Sun, why don't we feel the acceleration of that slingshot? How it is almost like the same angular momentum is preserved?

Why are you talking about _baryonic_ matter. Surely these 5% are also made of electrons, not just protons and neutrons, and the electron is an elementary particle, not a baryon. Even if the mass of the electron is the smallest of all charged particles, that probably still amounts to a good kg of feathers when you add up the trillions of trillions of electrons in the Universe, right?

This also goes with the conclusion found with a Japanese team. they discovered that if they adjusted the distances to galaxies they could eliminate the need to have dark matter as a thing. The Intergalactic media is loaded with ion that falsely red shift galaxies. Adjust for the media and bobs yer uncle theres no dark matter.

Right my ass. Still talking about the big bang no one buys anymore and black holes that don't exist as defined and that definition keeps changing to cover up how wrong hawking was, you should go look into the electric universe model you will find some real answers. The linear expiation of the universe is false its like saying the Earth is flat.

for me we only have space and matter. space is infinite while matter is not.. the universe have boundary if we are talking about the edge where matter stop existing.. but universe has no ending if the edge of space is what we are trying to reach.. why i didint include time? time is what we use to calculate distance and duration of an event.. we cannot scale the diatance between matter using our unit of measurement.. i think that is the reason we include time.. this is just for me.. we have our own conceptualizations.. as it said dont be afraid to be wrong.. respect is the key

@Derek1978There is a wikipedia article called "cosmic distance ladder". There are plenty of YouTube videos. Having said that, it's some of the most boring work astronomers have to do, even if it is some of the most important.

@Dirk Knight I have always wondered how they could tell the difference and have never seen anything explaining it

That's a very hard one. It's called the "cosmic distance ladder" problem. For stars that are very close one can use the parallax method, i.e. we measure the angular displacement of the star in the sky that results from Earth's motion around the sun, but this only works well out to maybe a few 10,000 light years, beyond that the angular displacements become too small for even our best instruments (currently the Gaia spacecraft) to be precise. If we want to measure the distances to other galaxies, we can use bright objects that have a known luminosity and then we can estimate their distance by the amount of light that we receive from them. The hard part is the estimation of the absolute luminosity of these "standard candles". This requires very precise models of star development and precision optical observations on many objects. Depending on the distances that we are interested in, we also have to use different kinds of such stars, like Capheids and type I supernovae. These observations are being constantly refined. We are far from done, yet. As to the time at which the light was emitted, that can be estimated with relativity. The difficult aspect there is the question whether the universe expands with a constant Hubble "constant" or if the expansion is variable. The latest research strongly suggests the latter, so both distances and timing take on some non-trivial physical characteristics. It's a little bit like asking how long a swimmer has to swim in a river with changing flow velocity. It's obviously harder to swim upstream than downstream and if the river flows too fast, one can't swim upstream, at all. Basically all of the visible universe is like that to us, already. We can never reach any of it, no matter how hard we try. So in essence we are living in an ever smaller bubble of space that is relevant to us. Everything else is already "in the past" and will always stay there.

The scientist in me is still skeptical that we're not falling victim to confirmation bias because it feels almost too convenient that we expected 5% and then it actually happened to be 5%. Maybe a decade from now someone sees it from a fresh perspective and realizes it's not adding up the way we thought and we forgot to carry that 1. Then with the new calculation a new mystery arises that leads to understanding dark matter another decade after that.
