Alex Filippenko: Supernovae, Dark Energy, Aliens & the Expanding Universe | Lex Fridman Podcast #137

I LOVE AND HAVE GREAT RESPECT FOR THIS GENTLEMAN. HE WAS MY ONE OF THE BEST ONLINE TEACHER. THANK YOU SIR.

Thanks Lex once again 🙏

Your comment about "Who cares about a monkey" when talking about Big Foot, had me rolling on the floor. Makes me think, say that we descend from chimps, would that also make Big Foot a relative descendant?

How do you slow down the Star Shot camera traveling at 99% of ls to be able to take a picture?

True

Seems to me the true fountain of youth is having a deep passion and interest in whatever it is that you do. His character and the way he speaks and carries himself is like that of an enthusiastic 25 year old. Top form Lex, very inspiring and thought provoking!

Aliens, most likely are other dimensional and the very creators watching us. Or time stretches so far we rarely live in the same timeline as each other or we're already a simulation which has been created again and again infinity which is why everything is made up of the same thing and we can only see so far amf use so many dimensions. There's a limit to our ram or programming

Appreciate this discussion but saying we know a lot is hilarious. We know nothing besides our own physics that are continuing to be discovered. We have no clue at all if what TF we are actually doing here flying through space and why it's finite.. why we can only perceive time as present time. Why we can't use most our brain. What dreams even are. Why we can't find any other life. If we're just a simulation! Why we are apparently so much different than everything else on earth. What's deep in our oceans. Why we can't see more dimensions that are likely there. I think you get the idea we know really nothing!!

Please get this guy on again his energy is contagious. I love this man. His enthusiasm is infectious..

We live in a finite simulation, true "reality" exists in the 5th+ dimension. To be truly "advanced", why be constrained by flesh? This notion that we can't possibly be "alone" in the universe is utter hubris. We are simply confined within physical dimensions. The BIBLE clearly reveals this, science is the "religion" that needs to catch up.

nobody knows how big space will grow.... The space is still small ... but what part of space is important, is to see your part to keep expanding in time... if our part of space time stops and space starts building its self into different directions ,,, time will fade away from our expansion???? something like that ???

i respect Alex intelligentance because he is very. I would argue its not wise of us to assume that we know alot maybe we know alot based on what humans new 50,000 years ago but i personally dont agree. I think its more likely were closer to knowing nothing rather than closer to knowing anything im my opinion we only know 5% of the knowledge thats available to us throughout the universe. 100 billion light years in every direction... we dont know anything...

You always provide the best content and use the very most intelligent guests. I love the feeling I get following your conversations. So fluid, so sincere, so beautifully

Lex I think you’re talking to an absolute human computer! I would say he’d nothing to learn from owning a computer, henceforth I bet he’s learned everything from living through his very deep thoughts and mathematical equations and that he might even use pencil and paper to work out his theories. Thanks for having this GENIUS on your podcast!

Great having Javier Milei's brother on the program!

He reminds me of Feynman the way he talks so enthusiastically. Love this podcast!

Us government hide lots of positive tech please look into plasma kinetics

Would an exploding star be to us an ancient image in the very distant past?

"One feels as though they are dissolved and merged into nature." The phrase "Albert Einstein" is written at the bottom of his shirt.

We now have a testable Theory of Quantum Gravity backed by empirical repeatable experimental and observational evidence with precise and predictive physical and mathematical equations. Check it out and see how gravity was quantized and unified with Quantum Mechanics. Just google the name Roel Real Rovira. It will lead you to the only scientifically proven Quantum Theory of Gravity to date.

how intelligent is this man like he is not from the planet earth

I clicked on this thinking this was the new president of Argentina.

One of my favorite interviews of yours Lex. You’re both such beautiful humans. The Human race is lucky to have you guys. I hope you bring Alex back again, not sure what else you could talk about, but you always surprise me with you’re questions and introspection. Thank you.

Aliens showed up recently and I'm a giraffe

Loved this interview

lol we live in the 4% of the universe and the rest is dark stuff but !

I was so excited to stumble on this episode. I don't know how I missed this one, but I'm so glad I found it. Thank you gentlemen!

Lunch with Feynmanfor asking questions, sign me up.

F

All Masonic lies c mon u can do better than this. On about living on Mars we’ve never been to the moon yet. Ever. One lie at a time please

such a good professor and good person.

JUST the fact that science has TOLD us without doubt that our sun won't burn out Tomorrow, not for millions billions, we can at least not worry/wonder aboutTHAT one!

What if in the story if Noah and the Ark, having 2 of every animal, meant having the dna of everything and not having the physical animal so they can be made later on.

WE NEED MORE 'objective open minded scientists' such as this Gem! 💎 Great podcast! 👍 🙏

Also.
With the most love.
The space between astrological bodies could allow for local space to be bent in a way that a spherical body inverts space

Hey Lex.
Lots of Love.
I have a question.
If there was infinite matter outside of the visible universe, would it provide enough mass to accelerate the known universe outward?

Hamas, just like ISIS, is a CIA/Mossad psyop that's been a tool to justify the genocide of Innocent Palestinians for decades. Do people really not see the truth about vile vampire Jew terrorists?? Sad.

Lex?? Pod with stevo? It sounds silly but maybe it might be positive?

Can or must we talk about our own demise?

With Russia. They loved venus..

If one is threatened by tyrants/criminals that their life and well being, even those around them closest would be harmed if they came out with the credible evidence, they are unlikely to make the change the greater good of all. Many believe that a conspiracy theory but the reality is, its an open faced conspiracy in our eyes, those that come out get shut down and threatened for lesser classified topics. We know thanks to Wilbert B Smith we know this is classified two points higher than the H-bomb, so it has the most defense against letting the public realize what we already know.

This interview tickles my brain so good, I could fall asleep listening to it on repeat.. and I will😴

Wonderful! Thank you both for this.

Leviti...levity...?
That's a word I haven't seen in so long, I don't remember...if I ever even new...how to spell the word.
What was I saying?
Oh yeah...
That's why I come here.
