Event Horizons musings
Posted: Sun Jan 12, 2020 4:56 am
nFA said something in a recent thread that caught my attention,
intrigues me and fires my imagination.
the event horizons surrounding black holes,
of which there may be billions, I have no idea,
and the event horizon that is surrounding our Universe,
(beyond which it is expanding faster than the speed of light),
are exactly the same.
I would like to compare and contrast the 2 event horizons.
maybe there's really not much more to it.
but maybe there is.
for example, is the event horizon beyond which the Universe is expanding faster than light,
moving away from us?
and therefore getting larger, and farther away all the time?
I would think that it must be.
and that the part of the Universe that already is moving faster than light, just keeps moving faster and faster.
also, think about how the speed of light is related to both kinds of event horizons.
and the Universe event horizon, is sort of like an inside out or opposite in a way,
compared to the black hole event horizons which enclose a space.
both event horizons close us off from information.
the Universe event horizon is like an expanding bubble.
nFA, where is the Universe event horizon with respect to the Observable Universe?
are they at the same place, or near each other?
also, I am sure that the Universe event horizon's location will vary with the observer's location.
thats all I can think of for now.
any thoughts, guys and gals?
