We will calculate the Gravitational Time Shift to see how much longer you would live if you were to live on 1) Earth, 2) Sun, 3) White Dwarf, 4) Neutron Star, 5) the Event Horizon (at the black hole).

As an industrial engineer heavily involved in time studies, this is what made me believe in the Quran. (SUrah 70 verses 3-4) touches on this reality long before the science was available to detect this phenomenon.
What do those verses state?
@@MichelvanBiezen It says that in proximity to God there are pathways of ascent through which the angels ascend to the presence of God. And a day at the height of ascension is measurable to 50,000 years in the lower heavens below.
So basically this verse hints at the relativity of time based on elevation, and it points out the idea that the higher the elevation the more quickly time seems to pass. Remarkable.
To add, there is another verse (32:5) that states a day in the lower heaven is like 1,000 years in earth time. The Quran made these bold claims centuries before modern science could prove it.
very interesting.
Scientists confuse clock time and gravitational time ,clock time is constant only gravitational time viries with respect to the change in gravity,the highier the gravity the smaller the time vice versa is true bcoz gravity is space per time
Fascinating. TY
You're welcome!
@Michel van Biezen thank you sir for giving me your time and replying i appreciate that.
( i couldn't reply on my original comment because you can't see it right?( i promise you i will delete this comment after you see it i don't want to make your comment section messy😉)

i was just worried that my other account(tahycoon1440) got muted because i commented in the (Astronomy - General Relativity (16 of 17) ) video and when i switched to this account i couldn't see my comment so i was afraid that you displayed my comments in your wonderful channel. i hope you didn't do that😢😊 . i am Enthusiastic to see your opinion on that comment.
Yes, I strongly suspect they were clever fellows. :)
I think your interlocutor hit the nail on the head, for you time just passes, it's only in other frames of reference you live longer. So the spaghettification probably isn't worth the bargain. ;)
Shouldn't black hole singularity be extremely hot since all the matter in it is crunched down in such a small space
Sir, Is t0 >t? or the other way round? from from formula t0= tx.., and the diagram,it seems t0
Another great vid, thanks Professor. :)
-two thoughts, what about some sort of special computer in a powerful gravitational field. It would take AGES to do just one calculation.
Then there’s the Dipole Repeller, the thing noone talks about because black holes are so much more exciting!
-so do computers work faster there? And how can we build a machine that builds space, the opposite of a black hole?
Here’s hoping this makes sense, and thanks again, your vids are like a breath of fresh air.
I am unsure how to obtain the time we add onto our 80 year lifespan. I get the decimals but how do we convert that to how many seconds or hours to add on?
Sir have you considered doing more advanced general relativity problems? Your lectures are very clear and great to watch, and there is not many general relativity videos on youtube.
Yes, but not right away. We first have to complete a number of uncompleted topics. Thanks for the suggestion.
@@MichelvanBiezen Thank you sir, would love videos about Einstein field equations and problem solving with them
Hi sir, Omar present......................
Gravity slows time does it also contract length. Does shortening of wavelength during blue shift in a gravitational field indicate space contraction & denser space near massive body.
Not sure if we can call it "space contraction" and "denser space"
Master good morning, please check the initial screen of the video, the calculation for the sun has an extra 9, only on this screen. The table during your presentation is correct. congratulations i like this theme.
Thank you for letting us know.
Wonderful sir

Your few minutes equal hours of deep thoughts because of your strong attraction
Gravitational field slows time. Does electric field which is far more stronger also slow time?
No, it does not.
@@MichelvanBiezen There appears to be some hidden link b/w mass & time. Both gravitational field produced by mass and motion of mass slow time.
Professor, from which frame reference does that apply?
My understanding is that what you talked about depends on the observer.
The observer sees their clock slower but the person inside the gravitational field feels no difference and for him everything is normal.
Is that correct?
I have one doubt could i ask? And where could i ask? M unable to upload my question?please help
You can ask like this as a comment on any video. Don't continue with this comment but start a new one or I won't find it.
Sir are u saying we don't age in black hole event horizon??
Relative to an observer on Earth, yes.
@@MichelvanBiezen ok sir 🤩🤩
*Voldemort wants to know your location*
Sir, so does this term r refer to the radius of the object on which we stand?
Yes.
@@simonbox5687 ok.. thanks...
If you're falling into a black hole, an outside observer will never see you cross the event horizon.
That is an interesting point which I have wondered about myself. In addition, the closer an object come to the event horizon, the more the emitted radiation will be gravitationally redshifted to the point where it will be shifted out of the visible light range.
@@MichelvanBiezen on YT, there's a series of lectures (from Stanford) given by Leonard Susskind with regards to General Relativity. In one of them, he describes this effect.
