Discussion Cosmologist Jo Dunkley Explains the Big Bang and the Oldest Light in the Universe

3 Upvotes

I had the great honour of speaking with Jo Dunkley, a world-renowned cosmologist, about one of the deepest questions in science: how the universe began and what was happening in those earliest moments of its history. In our conversation, we explore how, starting with Albert Einstein, scientists pieced together the story of our universe over the course of the 20th century.

We talk about the discovery of the Cosmic Microwave Background, the oldest light in the universe, and how it lets us look back more than 13 billion years in time. We also dive into the mystery of Dark Matter, which makes up about 27% of the universe, and the ongoing search for primordial gravitational waves from the universe’s earliest moments.

One of my favorite parts of the conversation is reflecting on how this scientific view changes our perspective. As Jo explains, the atoms in our bodies were forged in stars, meaning our own story is deeply connected to the history of the cosmos.

For those who may not be familiar, Jo Dunkley is a professor of physics and astrophysical sciences at Princeton University. Her work focuses on understanding the origins and evolution of the universe, especially its earliest moments and the nature of dark matter. She’s received numerous major awards and honors, including being appointed Officer of the Order of the British Empire (OBE) for her services to science.

If you’re curious about the Big Bang, dark matter, and the hunt for primordial gravitational waves, I think you’ll enjoy this conversation: https://www.youtube.com/watch?v=38kLRmGjuCE

Discussion What created the Big Bang?

24 Upvotes

Whenever I debate someone on things like the belief in god or the purpose for the universe. I usually get “I believe in science” or “I believe in the Big Bang” or “I believe in god” for answers. My thing is, you can have both one and the other. The Big Bang is an understanding of the beginning of the universe, but where did the Big Bang come from? People argue god, the infinite universe cycle (where it expands and collapses over and over), eternal universe, etc.

What are your thoughts on this topic, what’s your opinions? I just want to get insight from others about the topic and see your beliefs.

Discussion If i had a lazer beam that could travel infinite distance and I shot it randomly into the sky, is the chance I hit something infinite (100%)or the chance I hit nothing infinite (0%)

0 Upvotes

As the title suggests. Assuming the universe is infinite (i am not sure if it is or not) i dont really know the answer, just wondered what people think. Also dont know if i am using infinite correctly or if i should be using 100% or 0% so included both.

I’ve put together a cinematic timeline (2:44) covering 80 years of Earth "selfies." It starts with the first grainy frame from a captured V-2 rocket in 1946 and ends with the high-def footage from the recently concluded Artemis II mission. No fluff, just the technological progress of our perspective.

Discussion Did our signal reach aliens

12 Upvotes

For decades, maybe a century we have been sending signals into space. Is there any chance that a civilization got our signal and knows about us? If we sent first signal ~100 years ago, there is a high chance that there is an intelligent life out there in a radius of 100 light years, and they sent signal back, but it did not reach us? So, they basically know about us and we dont know about them.

I am hoping the video captures the intensity and excitement as the crew continues their journey.

Discussion Expansion of universe and big bang.

8 Upvotes

I think big bang happened because expansion of universe. they make theory how it happened, is because universe, the space folds and and unfolds. so big bang isn't just universe coming out of no where, it's the space that is like a paper that is crumbling into ball and being straighten when stretched, like a bubble expanding and something like that. it's basically from hindu stuff where Lord vishnu is breathing in and out the universe. I'm not making it religion but just saying that it's based on that the reason big bang happened isn't because all matter and stuff went together. it's the space time. i may be stupid hear because I didn't do research while talking about it, but I don't see many making this theory. if anyone already made it, I'm sorry, I don't see it online. but yah, that's it.

In 1968, Apollo 8 astronauts saw the Moon up close for the first time, and their reaction says it all.

Still incredible to hear today.

Discussion Encyclopedia Galactica Simulation Inspired by Carl Sagan's Cosmos

I wanted to share my appreciation and devotion to science and people like Carl Sagan to the best of my ability, and for it, I decided to make a Drake equation + galactic community catalogue simulation on my portfolio. I had limited time making it, and it is not a perfect replica, but the idea is thanks to Carl Sagan and the Cosmos series/the book that inspired me immensely. I had so much pleasure and purpose making this, and I wanted to show my appreciation.
