Physics explains everything - Ask a Spaceman!

What blows me away about the universe? How is it all connected? How does universality give physics the power to explain everything? I discuss these questions and more in today’s Ask a Spaceman!

Keep those questions about space, science, astronomy, astrophysics, and cosmology coming to #AskASpaceman for COMPLETE KNOWLEDGE OF TIME AND SPACE! Music by Jason Grady and Nick Bain.

Wow, hello! You did a great job in the UFO film, I really liked)) I am from the Makar Svetly youtube channel

I wanna thank you for all wonderful videos that you're uploading! The quality of content is astonishing! You take such complex concepts and break them down for us, who wanna know more about universe in such efficient way! Please, don't ever stop!

I enjoyed your space radio last time, it doesn't really happen all to much that I laugh out loud when in my own. Really appreciate you.

Interesting video, paul! I love you and your channel! Thank you :)

What is the biggest (relatively close) galaxy group outside our Local Group? I'm looking for a galaxy group that still can hold together because of the expansion and not break apart, similar to our own local group. Looks like the Bullet Group is around 120 times as heavy, but is there another one?
Interested because of the heat death and what group should we in a far future try to reach to improve the time it takes before it appears.

Explain why cosmologists ignore un-fusing all objects (atoms, galaxies etc. ) in the universe when "running the universe backwards" to it's "initial singularity". How is this justified?

QUESTION!! How does the PKI infrastructure allow two independent observers to agree on the outcome of an event in very different space times? Doesn’t this fly in the face of shroedingers dead cat? And If so, why does quantum entanglement rely so heavily on prime numbers? You might need Fraiser Kane to help with this one he used to be a software engineer

Kindly explain quantum mechanics in cosmos

[paulthompto]

That is what Isaac Newton did. He realized the universality of the force causing an apple to fall (maybe) and realized that it is the same force that keeps the planets in orbit around the Sun.

Actually physics is not the same in the Eye of Terror

Kind of ironic "Gravity started it all " and yet we still don't know what the hell it (gravity) really is ... lol

[robrtoantoniobarra]

I'm curious about your beard dude😬I want one like yours😝 please respond

[luislopes]

It seems a bit arrogant to assume that laws of physics are immutable across all space time.... Evidence is starting to appear hinting that universe isn't isotropic and homogeneous and constants probably aren't so "constant", after all..

Loop quantum strings anybody ? ? ? Lol sorry 🤔🙄

[guillepk]

A bit boring, I'd say. I've enjoyed other videos much more.
