Dark Matter Explained Neil DeGrasse Tyson #universe #physics #shorts

Dark matter, dark energy explained Neil DeGrasse Tyson The universe is full of matter and the attractive force of gravity pulls all matter together. Then came 1998 and the Hubble Space Telescope (HST) observations of very distant supernovae that showed that, a long time ago, the universe was actually expanding more slowly than it is today. So the expansion of the universe has not been slowing due to gravity, as everyone thought, it has been accelerating. No one expected this, no one knew how to explain it. But something was causing it.

I love the way he explains things. So regular people with normal jobs in society can understand 😬

I recommend the term, Universal Missing Mass, that way when you are asked what you are working on you just go "umm" !!

[syedarmaghanhassan]

It is dark until I shed some light on it.. 😊

We should call it ‘Fred’. He is always ghosting for man U.

I've always said the one thing not accounted for in that equation is the amount of sheer energy around us. The small reactions happening on a molecular level literally filling every space in the universe. The energy from atoms smashing together. The wind against other wind. The wind on the grass. The wind on the house. On the road. Every single atom In the world, even oxygen. Smashing against other atoms constantly

I think "Missing Mass" is a hell of a lot cooler than "Dark Matter."

Dark Matter sounds like it's trying too hard to be in a cool, Sci-Fi movie.

Could it be that there are lots of black holes roaming about?

Do we have an estimate of how many black holes there are?

[Kaiser-Soze]

You added it up? Must be an approximation, or you would be still adding!

[emoji_page]

What about the gravity from other time periods was that added?

[mikey]

Dark gravity, measuring it and confirming our measurements and naming fred-/+

[dreamarouse]

This thing which we know nothing about.(5 sec later) We have known about dark matter since the 30`s

[Kendrick-eg]

🤔 would a a metric ton of tungsten and tungsten equivalent dark matter share similar properties…. Misnomer 🤷🏾‍♂️, periodic table is relative to visible light….perhaps

Yet it doesn’t stop him from telling people that dark matter means Einstein greatest blunder was not a blunder and the universe is indeed static (always existed). Despite that we see galaxies spinning away at a vast rate. But dark matter will eventually pull it all back I and Neil can know God was not needed.

Yall, its simple.. we miscalculated the mass of earth when we made that formula bc its hollow. Gravity is actually 47% stronger than u thought

[marktombazian]

Gravity is an inverted vibration that pulsates inward pulling in instead of pushing outward. It is the opposite of the expanding vibration of the cosmos.
Everything has its counterpart...aum/Om is the sound of the primal vibration of creation which you can hear if you tune your hearing to the inner sound, what is called the Word of God.. gravity is it's perfect opposite. Aum/Mua....part of the balance of nature.

[ShadeIllusion]

what if gravity itself IS the thing, rather than gravity being the result of something unknown. Gravity might just be the dark matter you've been looking for, but you chicken and egged it the wrong way.

[gerrydescoteaux]

Neil, could dark matter really be a measurement error? What if black holes that billions of years ago swallowed entire proto galaxies and are now invisible to our instruments but just might be responsible tor the observed gravity? Can we really be confident that we have detected every one of these really massive blackholes?

Of course, without the supposed dark matter/energy mystery, funding could be harder to come by. . . ;-)
