Time: How to Stop it and What Will Happen? | Lecture 6: "Big Challenges for Science" Series

"Big Challenges for Science" is a series of lectures arranged by The Black Hole. Designed for high school and above audiences, these lectures are delivered by Pakistan’s acclaimed nuclear physicist Dr. Pervez Hoodbhoy.
“Time: How to Stop it and What Will Happen?” is one of the lectures of the series. It will be a 45-60-minute presentation followed by an interactive Q&A with the audience.

Mind blowing stream. Thanks a lot.

[@hirashergarh5718]

Salute. Standing for one hour and thirty six minutes at this age is huge stamina.

[@muhammadadeemakram6717]

When you do something you love doing, you dont get tired!

[@zeeshanjawaid5380]

Thank GOD that Mr. Hoodbhoy has delivered a lecture on a topic related to Physics.....which is his field....

[@hrishikeshkhaladkar4963]

Your lectures series are highly inspiring sir..hope you explore many topics which will create curiosity with the new generation ahead!! A very well designed efforts!! Best wishes

I’m speechless after watching the caliber of discussion. God help Pakistan!

[@rizwaninias]

Speechless in a good way ?

[@Ancientscripturestoic]

Sir the way you say Einstein i can feel how much you love him ❤😅i love you sir ❤❤Hoodbhoy ❤️❤️❤️

[@bhuvanmittal4977]

Parvez Hoodbhoi is is genius who explains the most complicated aspects of science in most simple and easily comprehensible way. He should be in Indian science arena, hos potential and capacitance will be put to awesome use which will be beneficial for both, India and Parvez Hoodbhoi.

[@sumitmitra7813]

I mostly understood it. But in India science is taught in English. So I faced a bit problem. Pls add English captions Sir.

[@advocatehafiznasirmahmood5980]

Good effort 👍 sir you are great

[@bvm3261]

Concept eloquently explained Thanks Sir .👍🙏

[@Anmol_Thakur888]

Great lecture.

[@sandippan2007]

Professor parvez looks an academic activist. No professor in India spent time in teaching outside classrooms. They didn't educate the masses. Many professors are bad teachers. Pakistan has Parvez. I see no one in India. Someone should prevent Indian professors from feeding on the government paid salaries and teaching not. Look at their poor quality papers they put in Indian academy of Science, Universities and other foras. Education quality in India and Pakistan is equally poor. Professor parvez is a hope. He is a real teacher.

14:28 Oh there is a mistake in video, speed of light is 300,000 (3 lack) KM/Sec. So not 300,000 km/h (as said in video) but km/second.

[@tariqahmed5513]

Thanks

[@faisalnadeem1863]

sir ! captions should be added in your video for other people out of the Pakistan. they can also take benefit from your informative videos regarding science .

[@HassanAli-ly9ti]

Hat's off sir ❤️❤️

[@MuhammadIrfan-jk5ll]

Always Waiting for your Lecture Sir

[@MuhammadSaleem-kf4bz]

God bless U 4 ur services

[@prasadkulkarni9693]

Throwing photon and return in time is x So what is effect of gravity on photon

[@nayabzafar5]

You’re my favourite 🎉🎉

[@tariqahmed5513]

Love u air

[@dryunuskhan4613]

Thanks a lot sir for wonderful lectures. How may i attend ur lectures/ sessions live?? Thanking you

[@davidsharma9673]

Sir can you do science without time ? Time may be an invention of mind ? Thank you for sharing

[@MuhammadAhmad-sp6sj]

Excellent initiative

[@geraltrivia6678]

great

[@tariqahmed5513]

Good

[@goodpersonff]

Great sir your efforts to change Pakistan is unbeatable 👌👍💯♟️

[@strategicbalance]

so sir what are the similarities that time and gravity have

[@FooodConfusion]

Good job

[@ShikharMasseyMusic]

Wow

[@MuhammadSaleem-kf4bz]

Very active man

[@muhammadahsan2516]

He is not a medical doctor. He is also a human and he can also does mistakes

[@agar1974]

حرکت وقت ہے۔

[@rohitwalke2129]

Xplaning very complicated subject in simple and basic level, 🙏, sir if possible please visit our Indian universities as you get availablelity, also requested once to visit IISC Bangalore.

[@TalentMixture2024]

What stamina after researching alot He could not Find or understand the CREATOR OF WORLD , this is the big failure

[@chxwv]

Title should be physics made confusing

[@chxwv]

Omg , he thinks normal heart rate is 30/minute , please note it’s abnormally and dangerously low to have that rate, and 70 bpm is not fast ! That’s actually normal resting heartbeat

[@tariqahmed5513]

Mice

[@arali4554]

His responses to the questions are sometimes not relevant and unclear. It seems he is not deeply averse of these subjects. Style of communication is also more like a class room lecture and lacks clear examples. For example, Einstein's relativity distance/speed/time example he tried to explain may be difficult for the audience watching this video.

[@SahilSahil-ig8ie]

Be like Islamic.
