American Museum of Natural History Astronomer Dr. Jackie Faherty joins WIRED to answer the internet’s burning questions about the cosmos. How old is the universe?Could a solar flare destroy the internet? What would happen if two stars merged together? Where was the Big Bang located? Are non-spherical planets possible? Answers to these questions and many more await on Cosmology Support.

ABOUT WIRED
WIRED is where tomorrow is realized. Through thought-provoking stories and videos, WIRED explores the future of business, innovation, and culture.
The answer to the multi universe is far stronger then maybe given the necessary energy to kick of inflation the scale facotor or radius of the universe increased by 10^26 in 10^-32 seconds. So in one full second at that rate the volume cubed would be 10^78 every 10^-32 seconds this is about equalivent to volume of our universe. By the time once second passes we get v=(10^78) to the power of 10^32 or simplified
Or 10^10^34. So by one billionth of a second we have insanely large amounts of inflation volume even if making one universe per our avg cubed volume is insanely low we would have 10×10000000000000000000000000000000 universe size volumes spawning in less then a billionth of a second.
My understanding is that the latest scientific data is indicating that the universe expansion is slowing down.
I love how much their experts want to share their knowledge. There are so many people who just know things to know them, but sharing information is one of the most valuable things a person can do and I’m so happy these people not only like doing this, but are willing to do so in a way just about anyone can understand. I can show these videos to my 7yo brother and even tho I’ll have to explain a few words, I don’t really have to explain the subject matter overall because once he gets the words, the explanation is good enough that he understands it as it’s been given. I can also show these to my nearly 50 year old mom and she can learn with me too and not feel like she’s being talked down to. Perfect format, perfect delivery
Space stuff is one of the most interesting things to me, when i saw this video is was so excited and clicked instantly on it.
oh this was beautiful, i love learning new things!!
Thanks doc!
Just like the 5 year olds comment said here. Please keep this series alive.
There was no big bang. The universe isn’t “old” just like there isn’t the “length” of height. The universe IS time. The “big bang” is just how OUR universe became measurable in time. Black holes at some point explode (for the lack of a better word) and it happens all the time. We are inside a black hole. Black holes exist inside of black holes. Black holes can collapse, expand, and invert.
Proof: E is not mc2, it’s mc2-1. At high speeds, energy rises non-linearly and diverges as v->c.
If the universe is infinite, at what point in it’s history did it become infinite? It obviously wasn’t infinite before it existed. So it must have become infinite, either at the point of the big bang, or at some point after that? None of this stuff is that easy to wrap your head around, but both of these conclusion seem particularly bizarre to me.
Might be my new favourite WIRED [Expertise] Support video. This or the most-recent coding University lecturer guy one. The best ones are not just because you (or I, at least) love the subject being spoken about, but it’s when the speaker has such passion with what they’re saying, it just makes it that much more special. That’s what always hooks me when Brian Cox does a documentary, or just speaks at all, you can tell the level of love/passion the man has for the subject, he just oozes with it.
Also, the de-classification of Pluto RUINED the entire way of remembering the planets and their orders that was taught to me;
My Very Eager Mother Just Served Us Nine Pizzas
Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto
I don’t want to -hear- read any suggestions that it was made easier because you can remove Pizzas and make Nine into Nachos. I don’t like nachos. I love pizzas. I’m also aware there’s no way in that to know which M is for Mercury/Mars, but sometimes it is important to try put some effort in yourself! (The same with Bonfire Day’s ‘Remember, Remember, the 5th of November’, which has the key flaw of the fact you can replace the most important part of that (the 5th) with any other date within November and the rhyme still works…)
‘What’s in the center of the Milky Way? Well it’s nougat and caramel, read the label!
The people getting her as a lecturer are the luckiest people out there. She’s amazing! Thank you ❤
her explanation is so clear
Interstellar mentioned
This always breaks my brain so if someone knows please help. If the universe is a balloon and we live on the surface isn’t that a 2D surface but we live in a 3D world? And what’s inside the balloon? 🤯
Bring her back she’s great
Straight Outta Holmdel.
Imagine our sun suddenly disappearing this very second. Now imagine that wave of a sudden loss of gravitational pull towards the sun, coupled with the immediate loss of sunlight. In the blink of an eye, 7 minutes after the sun’s sudden disappearance, our planet’s velocity would greatly change, rendering essentially everything on it’s surface destroyed, all while we were still trying to process why everything suddenly went dark. Survivors being left in the dark to slowly starve and freeze with no hope of saving themselves. That is what I would call scary af.
So much BS here…
I don’t understand one thing – If the universe began ~14 billion years ago, then how can it be infinite!!?? Please, someone, answer this.
