There are two things concerning famous Fermi paradox "where are everyone?"that crossed my mind. First, I have never seen a billionaire. Does that mean billionairs do not exist? No. It means they do not mingle with ordinary people. Ordinary people move in their ordinary circles while billionairs...

I often contemplate about Universe. My newest insights are as follow: Spacetime must be medium because it supports stuff. Nothing is falling nowhere and it probably has internal structure, armature of sort, in the form of underlying quantum field. But it is also a special medium which does not...

Do you know that little cars, kids play with, having mechanical coil inside that is rolled pulling the car backward and activated by simple release which pushes the car fast and rather far up front? Now imagine series of pulling and releasing. Even more, imagine torsion of the multiple piezo...

After 300.000km photon`s relative time changes for a second. Therefore, time didn`t stop for photon. It slowed down in respect to the environment moving at much slower velocity.

1) People claim that time stops when traveling at C due to the AE Special theory of relativity. That is not true. Look at photon: after it goes 300.000 km one second passes. Time didn't stop for photon. One second has passed. So, time does not stop for objects moving at the C rather it slows...

Chandrasekhar limit 1.4 is for the neutron stars. Tolman-Openheimer-Volkoff 3.0 limit is for the black holes. That means that stars which have mass 1.4-2.9 will become neutron stars. Stars that have solar mass of 3.0 or above will become black holes. Now I know. :-) Congratulations on 9/9...

Hi space.com community! I just solved nice quizz about black holes, with 8/9 accuracy, and I want to give you the link so that you can check your own knowledge: https://www.space.com/rogue-black-hole-isolated-discovery The article informs us that new black hole has been found, some 5 thousand...

I wrote: This numbers are just for illustration purposes. To get exact data we should take volume into the account not just diameter. You reply: Your error appears to be when you divide by diameter, you need to be dividing by the cube of diameter. You actually repeated my words.

Two important questions in cosmology are: 1) Is our Universe infinite? 2) Is our Universe just one of countless number of the Universes? Answer 1): With our modern telescopes we see 13.8 bn years age of the Universe. Since spacetime is expanding (stretching) the Universe is much bigger than...

In addition to my "Celestial objects size comparison" post, I calculated how much one tea spoon of neutron star weights. I didn`t want to use available data but made my own figure. As much as you can, always try to find your own example, instead of using already existing ones made by someone...

I respect every comment. There are no bad comments only bad replies to the comments. No one can limit my thoughts yet anyone can influence my thinking if something interesting is made present. I haven`t seen any argument in the favour of your statement that "time travel is not possible" other...

I wondered what are the sizes of celestial objects and decided to write this comparison. It will be written in the form radius / diameter and followed by approximate mass. Every number in this post is estimation I have found on the Internet. Earth 6.371 km / 12.742 km..... 5.9722 x 10`24 kg...

A lot of things wasn`t possible until they became possible. For example, humans couldn`t fly but today we have airplanes and we even travel across our solar system. I do not want to share your lack of imagination. If you want to believe that something is not possible, like time travel, that is...

I detect one huge problem in the scientific development, common to the human understanding of the reality, which is our narrow perception. Our frame of reference is always adjusted to our human terms: average human life is 70 years, modern science 400 years, human civilization 8000 years, first...

Because the light from your clock display will travel same like the light from the object of the experiment reaching us subsequently. That is why we need to record and inspect the recording.
