The Universe is getting smaller. Not the observable universe, which is currently a sphere about 93 billion light years across and increasing all the time, but the much smaller portion that we could ever hope to reach. Since the Universe is expanding, our cosmic playground is shrinking all the time.
Witryna30 kwi 2024 · In most cosmological models, even though the Universe is expanding, the value of the Hubble constant falls over time. The net effect of this is that the event horizon is larger than the radius of the Hubble sphere and the difference between the event horizon and the Hubble sphere changes over time.

WitrynaThey don't grow linearly, they grow exponentially. So to say that we are "about halfway" between Plank length and the size of the observable universe is not true. We are far closer to the observable universe's size than the Plank length. Also, the observable universe is literally observed, Plank length is not- it is mathematical. eni ipアドレスWitrynaThis is why the sun (our sun) looks small compared to the earth where we started, the distances grow and the scales become even more insane that it’s hard to comprehend ...
