Jaime Rudas replied to the thread I What Are the Limits of the Universe According to Cosmologists?.No, two-dimensional saddle-shaped surfaces have negative curvature but this is not constant. -
Jaime Rudas replied to the thread I What Are the Limits of the Universe According to Cosmologists?.Not in this case. The curvature parameter ##\Omega_{\kappa}=0.0007 ± 0.0019##, meaning its zero value is WITHIN the margin of error...

Jaime Rudas replied to the thread I What Are the Limits of the Universe According to Cosmologists?.The best model of the universe we have (the ΛCDM model) is fully compatible with both a finite and infinite universe. Moreover, the most...

Jaime Rudas replied to the thread I Potential biosignature found in Mars rock.Do you have a reference that supports this?
-
Jaime Rudas replied to the thread Does it make sense to build new radio telescopes?.Yes, maybe I didn't clarify that this was a sarcastic response.
-
Jaime Rudas replied to the thread Does it make sense to build new radio telescopes?.Yes, those official scientists always try to refute everything.
-
Jaime Rudas replied to the thread Does it make sense to build new radio telescopes?.Yes, but it is still worrying that more and more people responsible for this type of decisions think the same nowadays.

Jaime Rudas replied to the thread A Gravitational Analysis of Wide Binaries.Do you have a reference that supports this?
-
Jaime Rudas replied to the thread A Gravitational Analysis of Wide Binaries.Yes, but perhaps that's because the cited paper is from July 2011, while the main paper on asymmetric radiation of the Pioneers is from...

Jaime Rudas reacted to Ibix's post in the thread I Please explain how length contraction and time dilation result in a constant c with
Like.
You have forgotten the relativity of simultaneity, which is less popularised than length contraction and time dilation, but probably... -
Speed isn't a well defined measure in curved spacetime. So the answer is yes or no, depending on your coordinate choice.
-
According to one view of science, yes. But that is not the only possible view.

Jaime Rudas replied to the thread B What is conformal time?.Yes, that's more or less it: conformal time would be equivalent to the time in the last 46.5 billion years of a static universe, as...
-
Jaime Rudas replied to the thread B What is conformal time?.I don't see how this affects what I proposed. However, if you look at the bottom panel of Figure 1 in Davis & Lineweaver (which is where...

Jaime Rudas replied to the thread B What is conformal time?.The particle horizon refers to the current distance of the most distant (comoving) object that we can, in principle, observe today. The...
