I have a question for any astronomers out there: They say the universe is 13.5 billion old, based on out ability to see galaxies 13.5 light years away. If we can see galaxies that far away in one direction, and nearly that far in the opposite direction, wouldn’t that make it 26 billion years old?

No, just 26 Billion light years across................

Just out of curiosity does anyone know the tensile yield strength of the fabric of space-time?

Serious question.

Also, the theory is that the universe is expanding out in a 4-dimensional curved geometry.

One can envision this similar to a balloon expanding, and everything on the surface is moving away from each other, but there is no “center” on the surface.

Therefore, every point in the universe can see 13.5 billion ly in all directions.

At least, that is what I recall reading about the big bang in the past.

Here’s a question that’s troublesome:

If I can see a galaxy 13.5+ billion light years away, and I look right beside it into total blackness, how far away is that?..............

Let me know when they get a signal of — 3.14...Then I’ll be afraid....

First time?

https://en.wikipedia.org/wiki/Cosmic_background_radiation

“1896: Charles Édouard Guillaume estimates the “radiation of the stars” to be 5.6 K.[2]

1926: Sir Arthur Eddington estimates the non-thermal radiation of starlight in the galaxy has an effective temperature of 3.2 K. [1]

1930s: Erich Regener calculates that the non-thermal spectrum of cosmic rays in the galaxy has an effective temperature of 2.8 K.[2]

1931: The term microwave first appears in print: “When trials with wavelengths as low as 18 cm were made known, there was undisguised surprise that the problem of the micro-wave had been solved so soon.” Telegraph & Telephone Journal XVII. 179/1”

1938: Nobel Prize winner (1920) Walther Nernst re-estimates the cosmic ray temperature as 0.75 K.[2]

1946: The term “microwave” is first used in print in an astronomical context in an article “Microwave Radiation from the Sun and Moon” by Robert Dicke and Robert Beringer.

1946: Robert Dicke predicts a microwave background radiation temperature of 20 K (ref: Helge Kragh)

1946: Robert Dicke predicts a microwave background radiation temperature of “less that 20 K”[clarification needed] but later revised to 45 K (ref: Stephen G. Brush).

1946: George Gamow estimates a temperature of 50 K.[2]

1948: Ralph Alpher and Robert Herman re-estimate Gamow’s estimate at 5 K.[2]

1949: Ralph Alpher and Robert Herman re-re-estimate Gamow’s estimate at 28 K.

1960s: Robert Dicke re-estimates a MBR (microwave background radiation) temperature of 40 K (ref: Helge Kragh).

1965: Arno Penzias and Robert Woodrow Wilson measure the temperature to be approximately 3 K. Robert Dicke, P. J. E. Peebles, P. G. Roll and D. T. Wilkinson interpret this radiation as a signature of the Big Bang.[2] “

if the universe is in a forest and there is nobody there, does it actually hum.

This is a possible first step towards nanohertz frequency gravitational wave detection,"

See the source image

what's the frequency Kenneth?
