Do We Actually Live inside A Black Hole?

 

Do we actually live inside a Black Hole as postulated by the world renown Dr. Michio Kaku PhD, an American theoretical physicist, activist, futurologist, and popular science writer. He is a professor of theoretical physics who claimed that the entire universe is a black hole, and we live inside this blackhole? This means to me the black hole we live in must have a super light density, because we know that black holes are so massive, and its gravitational pull so unspeakably powerful that nothing can get out once pulled inside.  

His claim was sent to me by my brother-in-law Ong Geok Soo, a Senior Consultant Structural Engineer in a video here:

I wrote an article published on Sunday, May 21, 2023, to prove that even light cannot escape from a black hole here:

Dr. Michio Kaku claims that recent discoveries by the James Webb Space Telescope have shown that we live inside a black hole?  

Since I do not have access to the James Webb Space Telescope or any data, not even indirect data from any telescope, let alone the James Webb Space Telescope, I decided to do my own simple calculations to find out how could this be?

Let’s check this out:

The radius of a black hole called the Schwarzschild radius is the event horizon surrounding a non-rotating black hole. Any object with a physical radius smaller than its Schwarzschild radius will be a black hole. This quantity was first derived by Karl Schwarzschild in 1916:

The radius of this black hole is given by:

Rs = 2GM / c²

where,

G is the gravitational constant (6.6743 ± 0.00015) × 10⁻¹¹ m³ kg⁻¹ s⁻².

M is the mass of the Universe (10 ⁵³ kg)

Speed of light 299 792 458 m / s

Hence Schwarzschild radius of the universe if it was a black hole = 1.49 x 10 ²⁶ meters

Volume of the black hole is:

= 4/3 pi r ³

= 4/3 pi. (1.49 x 10 ²⁶ meters)³

= 1.39 x 10 ⁷⁹ m ³

Density of the universe if it was a black hole:

 Mass of the black hole universe / volume of the black hole  

= 10 ⁵³ kg / 1.39 x 10 ⁷⁹ meters

= 7.19 x 10 ^{– 27} kg m ³

Wow! What a revelation to me!  

The black hole in which we live actually has a super-super light density at only:  

0.00 000 000 000 000 000 000 000 000 719 kg per cubic metre.

No wonder we can all live and move and fly about so freely as if it was a vacuum except for the thin air we breathe even though we live inside a super black hole.  

If we lived inside a super-super massive black hole, I expected the entire world would be crushed into the size of a neutron 0.000000000000001 m (a thousand trillionths of a meter) in diameter.

But we are alive here with our imposing Warisan Merdeka Tower in Kuala Lumpur still rising to 678.9 metres high and we have not been crushed by the black hole to the atomic size of a hydrogen atom 0.00000000037nm (3.7 x 10 ^-19 metre). We can also see light from the Sun and stars coming in and escaping into space. What a wonderful we live in.  

 Wow! What a revelation!  Is this a dream? It is too fantastic for me to accept.

I hope Dr. Michio Kaku PhD is right, and I am right too?

 Dr. Michio Kaku uses highly sophisticated astrophysical mathematics plus findings from the James Webb Space Telescope to derive, but unfortunately, I only have simple physics at my disposal.

Thank you, Dr Kaku.
