Space: What is dark matter? - BBC World Service, CrowdScience podcast

Dark matter and dark energy make up around 95% of the universe and the remaining segment is normal matter - the stuff we’re all made of. Given that there’s so much of this dark material, could dark life have evolved? That’s what Gautam from Delhi in India asked CrowdScience.
Marnie Chesterton investigates with Dr Matt Middleton, Dr Burçin Mutlu-Pakdil and Dr Renato Costa. They unpick the physics behind dark matter and dark energy and test out some listener theories about what these mysterious mediums might be.
Yoseph from Ogden in the US questions whether black holes could account for the missing matter and it turns out he might just be on to something.

[@TSquared2001]

Good discourse

About dark energy, coud we consider somethink like the froce in Stars War.... because it's not always charlatanism to work with energy even it's not as trong as people imagine.... could we consider it's that the part of recover of Illness we can't explain, and not the mind, who could explained something about the possibility to get well by meditation, and respiration ?

Never say never. Indeed, we still know very little about dark matter and black hole

Bit of education, dark matter is a hypothesis, Black holes do not exist, Black is part of the electro magnetic spectrum, Holes can never have mass. They are called Dark stars and have been for over 200 years until a evangelical piece of crap asked an imbeciel in his class for a label , when their has been a label for over 200 years. John Michell (/ˈmɪtʃəl/; 25 December 1724 - 21 April 1793) was an English natural philosopher and clergyman who provided pioneering insights in a wide range of scientific fields, including astronomy, geology, optics, and gravitation. Considered "one of the greatest unsung scientists of all time",[1] he was the first person known to propose the existence of Dark Stars not black holes in publication, the first to suggest that earthquakes travel in waves, the first to explain how to manufacture artificial magnets, and the first to apply statistics to the study of the cosmos, recognizing that double stars were a product of mutual gravitation. He also invented an apparatus to measure the mass of the Earth. He has been called both the father of seismology and the father of magnetometry. Please stop listening to evangelical discovery institute level researcher's and do some actual research your self.

Scientist gives you a bag, “Here, have this bag of jelly babies. According to our current theories there are 100 in the bag but unfortunately you’ll only be able to find 5 of the non dark ones”. You give scientist a bag. “Here, have this bag of jelly babies. You may guess there are lots in the bag but there are only 5 and the bags a bit heavy”.

[@ossiedunstan4419]

You are almost as uneducated as those involved for 90 years on the biggest fraud in science since god. Their is no dark matter , Dark energy, 90 years and not one bit of evidence, Their is more evidence for the ETHER/EATHER than their is for dark matter and their is no evidence to support the Ether.

We are make with darkmatter

[@muratbayar3561]

So, what is matter? Everything we can see with light? If this is true, then who says that there aren't complex molecules that doesn't interact with light?

[@friarbishme]

still only theoretical, even though it makes sense.

[@public.public]

no. you are real in a real world.

[@friarbishme]

@@public.public you will notice the use of words like "Could" or "Might". They stay theoretical until proven
