- For years, we've been under the impression that the expansion of our universe was slowing down, but astrophysicist Adam Reiss' research could prove that all wrong.

Taken From the Series: Science's Greatest Mysteries
Does science have all the answers? This series examines some of the biggest riddles facing scientists today. We've solved some of the most complex questions about our world and the universe. But the more we discover, the more problems emerge. Exactly how old is our universe? Why are the two sides of our moon so different? How did iron from space end up next to the body of Tutankhamun? Each film in this series tackles a single question, visiting the cutting-edge labs running mind-bending experiments and meeting the dedicated scientists searching for answers.

My bully isn’t smart enough to understand this video lol
Different milkway has different time, and differnet multiverse have different time. Then there will be distruction and construction in every second in the vaste infinit multiverse.
If the channel operators see this. I really wish you put out more of your long form, compilation videos out. You can tell just looking at the view numbers on them.
What is closest: the singularity, or stasis in expansion?
If something is accelerating doesn't that mean some force is being applied to cause that acceleration? What would be that force?
Gravity... Gravity that didn't exist before the big bang. 🤷♀
Didn’t we figure out back in the 1970s that the expansion was accelerating????
we actually did much earlier xD
The evidence that the universe is expanding has been understood since the late 1920s. The data showing that the expansion is accelerating was collected and published in the late 1990s.
I wish I could live forever to witness the evolution of the universe
I wish i had a time machine caus i aint got time to wait like you🤭🤭
@@kiidkif2009 Good idea, but I want to experience the evolution slowly
awesome
The scientific method is a thing of beauty.
Didn't know the earth had a bar code!!!!😁😁😁
Our universe is 14 billion and 779 million years old.
i don't get it, i was told this in school 40 years ago already, what's new here ?
Surely you just cut the universe in half and count the rings.
But every time we cut it we end up with two uncut universe! It’s rings all the way down man!!!!
Cartography society probably decides limits
Really Really old....
Ok
Idk how old it is but is sure is older than dirt 😂❤️
So he discovered what Hubble did a century ago?....😅😅
Funny thing:
Job 9:8
He alone stretches out the heavens _ and treads on the waves of the sea.
Psalm 104:2
The LORD wraps himself in light as with a garment; _ he stretches out the heavens like a tent
Isaiah 40:22
He sits enthroned above the circle of the earth, _ and its people are like grasshoppers. _He stretches out the heavens like a canopy, _ and spreads them out like a tent to live in.
Isaiah 42:5
This is what God the LORD says_the Creator of the heavens, who stretches them out, _ who spreads out the earth with all that springs from it, _ who gives breath to its people, _ and life to those who walk on it
Isaiah 44:24
This is what the LORD says _ your Redeemer, who formed you in the womb: I am the LORD, _ the Maker of all things, _ who stretches out the heavens, _ who spreads out the earth by myself,
Isaiah 45:12
It is I who made the earth _ and created mankind on it. _My own hands stretched out the heavens; _ I marshaled their starry hosts.
Isaiah 48:13
My own hand laid the foundations of the earth, _ and my right hand spread out the heavens; _when I summon them, _ they all stand up together.
Isaiah 51:13
...that you forget the LORD your Maker, _ who stretches out the heavens _ and who lays the foundations of the earth, _that you live in constant terror every day _ because of the wrath of the oppressor, _ who is bent on destruction?
Jeremiah 10:12
But God made the earth by his power; _ he founded the world by his wisdom _ and stretched out the heavens by his understanding.
Jeremiah 51:15
He made the earth by his power; _ he founded the world by his wisdom _ and stretched out the heavens by his understanding.
Zechariah 12:1
The LORD, who stretches out the heavens, who lays the foundation of the earth, and who forms the human spirit within a person, declares: 2 ÒI am going to make Jerusalem a cup that sends all the surrounding peoples reeling. Judah will be besieged as well as Jerusalem.
Isn't it interesting that now science is discovering what the bible knew all along? ICR made a prediction before JWST was launched that they would discover full blown galaxies in the furthest reaches, and would therefore have to revise the supposed age of the universe. Guess what: This was true. In fact I have seen little from ICR or Answers in Genesis that contradicts known facts and much that answers many questions.
Cue the ridicule because I am sure it will come from my posting this, but maybe someone will be interested enough to look into it a little.
There is no way we can be sure how old it is
Very true but great idea to at least try to understand what is out there!
Well, actually, science does exactly that. There are ways you can KNOW things, not just best guess. Until you learn how scientists go through that process then you'll be under the false impression we don't have a way to know
Yes it is, we can literally see the big bang, to be precise time right after
Shoddy language use is causing countless problems in any scientific/philosophical discussion in this area. It is not just semantics. "Universe" means "everything," and if we find something outside of this current notion of "universe" it is, still, a part of the same universe. We should start calling the "stuff" we can see and know "cosmos" and stop using terms like "multiverse" because if it exists, it is part of the same "everything." Once this becomes the disciplined norm it allows for more effective and erudite discussions of the cosmos, especially "time," since time is a construct WE use to understand the process of change within our known cosmos. Sloppy language use denotes sloppy thinking, an inarticulate method of communicating what is known. The universe, being "everything" has always been here and always will be here, only changing form. Lazy thinking and communication won't change those facts. The correct terms prove me correct, I don't have to debate with any other commentators.
13 billion? I figured it be more in the trillions
That's pseudoscience, fairy tales for nerds 😂
