blue shift and speed of light

I just found out something that i never knew before in "Stephen Hawkings Universe" on TV.
Apparently mass slows down time AND light!
The Great Pyramid weighs (I think they said) 6 million tons, and all that mass is slowing light and time close to it.
So they said if you stand next to it, time is moving slower for you than for people further away, (just billionths of a second).
It means that if a map of the earth was drawn showing the areas where time is running slower because of varying mass densities near pyramids, mountains, mineral deposits etc, it'd be fascinating to see.

The fiction novel Heechee Rendezvous, uses the concept of black hole gravity wells as stasis areas for removing the occupant from the normal flow of time (outside the gravity well). It's a good book. Frederick Pohl knows his stuff.

Other novels have touched on this in different ways. A Fire Upon the Deep by Vernor Vinge, hypothesizes that the flow of time (and thought) are different outside of the gravitational fields inherent to galaxies.

And the Dragon's Egg by Robert L. Forward describes the life of a species which evolves on a neutron star (very high gravitational field) and their eventual interaction with the "slow" humans.

All fantastic books with fictional stories grounded in elements of real physics. So you can learn something while enjoying a good read

No ai problema

Encouraging, thank you Bev. Wish my postings were as clear to certain others

Thank you for that. It's not everyday….

Yes as Ros confirms it is toward the red end

That would make more sense wouldn't it

Wow that's a new one on me, puts a whole new light on things. It's not everyday….

Forgive pun
