The two most fundamental equations | Roger Penrose

The point of this statement in the longer video was to introduce the notion that if all matter decays after black holes have evaporated, eventually, the scale of time in the universe would end leading to a situation in which the universe has no scale of distance (s= d/t ie, so if t ends, d must also for the purpose of maintaining the speed of light).

Roger is my personal favorite Physicist. One of the modern greats!

[donleavell]

He gets to the point quickly and helps me understand to the extent I am competent to understand.

[jeffreysokal]

I love and admire Roger Penrose immensely. One of mankind's greatest minds.

[nrakis]

Brilliant man & he simplifies the concept's

[WhyInnovate]

Nice, finally understand why they are looking for particles at certain energy levels

[charastone]

I love this guy. We may never see another like him. Sadly.

Penrose = LEGEND!!!! (Spoken in SNL Liam Gallagher impersonation voice) 😎🤘🏻🤘🏻 Thank you Sir Penrose for all the beautiful explanations of physics over the years!!! Absolutely Magnanimous & Brilliant!

[budsurtees]

Penrose is one of the great minds in the history of science. Absolute genius.

[tophat]

What a nice chap. Very clear explanation too. I approve.

I've had more than one argument where I took the position that the E in both equations represented the same thing, and the other person was convinced they referred to two different kinds of energy. Something about "resting energy" being the problem with equating the two. With this video, I feel validated!
Thanks!!!

I was arguing that electrons (sorry, make that photons) are not massless because they have frequency. They are not massless.

I occasionally have dark thoughts of wishing my life to end or to have never existed and then I see something and think to myself, "Wow, I'd really like to learn more about that!" And then I have a purpose to exist for a bit longer. This is one of those moments, thank you for that ❤

[seabud]

A national treasure .. like David Attenborough 😀

Here are some questions about blackholes. If you fly alongside one and go past it, what's behind it? From the front it's a large black hole in space. But from the side is is a disc or is it a tube (or nothing). If you come towards its from the opposite direction, what do you see?

[LindaReeves-dy]

Very interesting, so complicated and yet so simple. God is the greatest mathematician.❤

Interestingly, if E^2=(h.f)m.c^2, then the gravitational force can also be expressed as the magnitude of the flux of quantity m (mass) flowing through a unit area per unit time The gravitational acceleration (g) from the current density (J), is g=(4πGh/Qc^2).(J).The mass to charge ratio M/Q=(Ghu/c^4)∆Q/∆S∆t, where u is the permeability. etc.

What great knowledge Thank you SIR for sharing

There's a lot of comments about all matter 'dissolving', but nothing about the constant that matter and energy are never destroyed. They only change form.
The Universe shows us that time is not a constant. Time is relative to speed, distance and the gravitational distortion of mass. Frequency lies in a range as we can measure or perceive it. Black holes may have a frequency so slow that time stands virtually still in proximity. Science is theories looking for repeatable confirmation.

This has a potential to explain mass hierarchy problem together with "A remarkable formal similarity between Koide's Lepton mass formula and a generalized Descartes circle formula is reported" paper.

How come i understood what he said when i listen the first time, but was totally confused when I listened the second time. But anyway his explanation was tremendous.
