I swear. He sounds like a really smart and really serious Mark Normand.

[RichardsWorld]

What happens if you "come" inside a black hole?

[chinaman]

So weird to see people saying Lex is not good at asking questions related to science.
Seems like people forget that Lex has a PhD electrical and computer engineering. Even if it's not a PhD in astrophysics. It's better than the people whose only school is Wikipedia. And is definitely smart enough to "ask questions about black holes".
Maybe he's asking simple questions for us dumb viewers.

Time is an insult, Death is an insult. (Kaecillius)

[Buringrud]

If earth orbited a supermassive black hole, would the night sky change faster than it does currently?

[Alcanica]

Inside black wholes are other universes. We live inside a black whole. Dark energy is just matter bleeding in from the outside into our universe. The cosmological constant is not really a constant. Its value is different for other universes inside black holes and its proportional to their size. The bigger the black hole, the more matter theyre able to pull in and thus more matter bleeds in pushing everything inside it apart faster.

The big bang was just the death of the star that created the black hole we live in. As time passed, more matter bleed in causing our universe to expand and to cool down.

What's up with some of these comments? I'm surprised by the amount of science illiteracy in here 😅

[stevenlopez]

Asking what time is like inside of a black hole is a dumb question…

What I think Lex is questioning is how time at the center might appear relative to an observer outside?

[iguesss]

Middle of a black hole is not kind to our forms of matter at this scale. Space between electron cloud and neutron to big. Reality is all in the gluons which are to never be exposed

[iguesss]

Jump in a black hole and the mini aliens will call you dark matter. Shine light in a black hole and they’ll see dark energy

[ManateeMentality]

Inside every black hole is the state of Kentucky

[andrewgrandfield]

Compare Sean Carroll to Neil deGrasse Tyson.

[iguesss]

If there are quantum black holes, what gets sucked inside, obviously not photons and neutrons, not even 1 could fit

[frankfowlkes]

His answer to the question was basically an exercise in semantics. The correct answer would be I don't know!

[swiftyspike]

I imagine it similar to a dark hallway that gets more narrow by a margin u can barely tell by the time you hit the end could be spit out somewhere

[Alexadria]

Lex is totally unequipped to be talking about black holes, especially with a theoretical physicist!

[liantolinawati]

I don't understand why black hole is cold, the more mass it have the colder it is.

[iguesss]

We can never touch a gluon but a black hole mashes them together like a trash compactor, from all directions, faster than the speed of light. Seemingly infinite inwards energy for structures “reality juice”

[draleigh]

Nice "theory" 😂 the whole staying younger moving at the speed of light doesnt even make sense. If youre moving at the speed of light all that means is you get from point A. To point B. Faster. Time doesnt magically slow down. If you set 2 watches on a timer, one left on earth. One on your wrist and you traveled to the edge of the universe and back the timers would still be the same time the only difference would be the space traveled.
