Jaime Rudas replied to the thread B Matter density right after the decoupling.On the other hand, the margin of error in calculating the age of the universe is on the order of hundreds of millions of years, so what... -
Jaime Rudas replied to the thread B Matter density right after the decoupling.I consider the radius of the observable universe to be, by definition, the greatest distance that anything could reach during the age of...

Jaime Rudas replied to the thread B Rutgers finds a transparent Einstein Cross - apparently a dark matter "halo"..I think you underestimate the enormous retrospective adaptability that these "theories" have always demonstrated.

There is a theorem, i think Hilbert, that says that a constant negative curvature surface cannot be embedded isometrically in three...

Jaime Rudas replied to the thread I Describing the Big Bang.The Gaussian curvature ##K## of the hyperboloid ##x^2+y^2-z^2=1## is ##\frac {-1}{(1+2z^2)^2}##. Thus, when ##z=0##, the curvature...

Jaime Rudas replied to the thread I Describing the Big Bang.The German Wikipedia says: Which, translated, would be: I understood that the hyperboloid didn't have constant Gaussian curvature. Am...
-
Jaime Rudas replied to the thread I Describing the Big Bang.Yes, I think I was wrong. Although I don't know if it's possible to define curvature at the "edge" of the pseudosphere (i.e., at the...
-
Jaime Rudas replied to the thread I Describing the Big Bang.Yes, maybe, but there is no such surface embedded in Euclidean three-dimensional space.
-
Jaime Rudas replied to the thread I Describing the Big Bang.No, two-dimensional saddle-shaped surfaces have negative curvature but this is not constant.
-
Jaime Rudas replied to the thread I Describing the Big Bang.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 Describing the Big Bang.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.
