Half the universe was missing... until now

Half of the ordinary baryonic matter has been tough to find but Fast Radio Bursts made it possible to detect the WHIM. Thanks to Kiwico for sponsoring this video! For 20% off go to kiwico.com/veritasium or use code VERITASIUM at checkout.

Where can I go to get more info?
I and many others in my community want to know ...
Who is in charge or who gives you the approval
to have these stories out in the mainstream
and claiming there is truth in it.

.. Why can I now see these evil enteties
 giving us false news everyday
and their fakery is everywhere
Was it the red pill

What do you do if you think you’ve made a scientific breakthrough?

Because of "the times" i have to ask,.... what is the "gender" of the baryons? Are they trans? 🤭🤭.....🤣🤣🤣..... sorry😔

Why do we talk as if the big bang was a fact, when it is actually a theory of how to universe was created.

Imagine just saying that God did it to solve everything. It's such a vague answer and doesn't explain anything.

I'll wait for a theory that doesn't require making something up that we can't detect in any way, just to fudge explaining why our current equations don't explain everything.

To anyone curious enough, yes. You quite literally found 6,200 nerds in one place.

When you say the radio waves encounter free electrons that slows them down as they travel through the magnetosphere, isn’t that impossible since they travel at the speed of light, hence the speed should be constant?

Is it possible that now that scientists have found all of the matter that they were looking for that they will stop looking? Wouldn't that automatically tend to validate their theory, even if it is wrong?

If that's the case, then the universe just doubled, not a missing half

7:44 yes because some of charge particles caused by lightening travels though earth's ionosphere to different regions and interaction also creates em waves

To think that half the baryonic matter in the universe is just atoms floating around in space is... weird.

Anyone else feel the radiowave that was just in time was the equivalent of getting help with your homework?

I love your videos
Speak out and remove all doubt!
I think FRBs are packets of data on the Uninet.
Speak out and remove all doubt!
A really great video, each part was explained super clearly but crucially you kept everything interesting too.
I love how theoretical physics comes up with a prediction and then computer simulations come up with a prediction but neither have seen any proof they are right until observational physics catches up and confirms everyone is right!

I think I totally underestimated the scale of the universe.....
If 70% of baryonic matter is not in galaxies but in betweem galaxies,stars and other seeable stuff
That means space is.....enormous, as there are literally 1-10 particles of hydrogen per cubic metre of empty space
Not to mention the ionised hydrogen that's present there as well
Space-time is.......
I don't even think I can imagine it, The scale
It is just so amazingly vast

Question I got when you said "20 minutes" after the big bang... Was the expanding universe so homogeneous that time was relatively running at the same rate everywhere in the universe? Or where are we counting those 20 minutes? Relativity just messed with my head 😅

I totally didn't get the explanation on 'why Baryon matters make up 5%of the universe', it pretty much jumped straight to the conclusion after the hydrogen atom ratio. I still liked this video for feed me with this interesting question.

Oh , by the way. There is a large sector of so called main stream science that now believes there never was a big bang. It is physically impossible for it to have happened that way.
