Take A Journey Into The Center Of The Galaxy – How Do You Find Exoplanets?

We live in the Milky Way Galaxy, which is a collection of stars, gas, dust, and a supermassive black hole at it’s very center. Our Galaxy is a spiral galaxy, which are rotating structures that are flat (disk-like) like a DVD when looked upon edge-on. There is also a bulge in the middle that consists of mostly old stars. When you look at a spiral galaxy face-on, you can see beautiful spiral arms where stars are being born. Our solar system is in the Orion arm, and we are about 25,000 light years (2.5 X 10^17 miles) from the very center of the Galaxy.

When You Shine Deadly Radiation on Glass (and food)

In this video I show you what happens when you shine radiation on glass. Why does it turn purple? I talk about how to revert the glass color change and how you can use Co 60 to shine gamma rays on food and glass!

What is Space Time and how it works? – Black Holes and Our Solar System Documentary

Space-time is a mathematical model that joins space and time into a single idea called a continuum. This four-dimensional continuum is known as Minkowski space. Combining these two ideas helped cosmology to understand how the universe works on the big level (e.g. galaxies) and small level (e.g. atoms).

Are We Actually Existing Inside A Black Hole? – How The Universe Works

A black hole cosmology is a cosmological model in which the observable universe is the interior of a black hole. Such models were originally proposed by theoretical physicist Raj Pathria, and concurrently by mathematician I. J. Good.

Any such model requires that the Hubble radius of the observable universe be equal to its Schwarzschild radius, that is, the product of its mass and the Schwarzschild proportionality constant. This is indeed known to be nearly the case; however, most cosmologists consider this close match a coincidence.

In the version as originally proposed by Pathria and Good, and studied more recently by, among others, Nikodem Popławski, the observable universe is the interior of a black hole existing as one of possibly many inside a larger parent universe, or multiverse.

What If a Black Hole Deleted the Universe?

They are massive, and extremely dense. They rip apart anything and everything that gets close to them. Their gravity is so strong that even light can’t escape. We can’t see black holes. But we know they have the destructive power to wipe everything out of existence.

How to Make Magnetic Bubbles With Paramagnetic Oxygen and a Giant Neodymium Magnet

In this video I show you how to make magnetic bubbles. I show you a few experiments to show how oxygen is paramagnetic and is thus attracted to a magnet. In other experiments this has been shown by pouring liquid oxygen over two magnets and watching it stick to the space between the magnets. In this video I use a giant monster neodymium magnet with gaseous oxygen in order to show you that it is still attracted to the magnet. I blow bubbles with oxygen and show how they are attracted to the magnet! This is an amazing experiment.

What is the most Powerful Object in the Universe? Is there a Black Hole in our Solar System?

No known object in existence has as clear a division between “inside” and “outside” as a black hole. We live and see the outside, and no probe will bring us information about the inside. We can send radio messages or robotic spacecraft, but once they cross over into a black hole’s interior, we’ll never get back those emissaries … or any information about what happened to them.

The boundary of a black hole is its event horizon. It’s not a surface in the usual sense—there’s no physical barrier—but it’s very much a real thing. Outside the horizon, an object can escape the black hole’s gravitational pull if it’s moving sufficiently fast; inside, it would need to move faster than light-speed, something forbidden by the laws of nature.
