How small is our universe? Video provided.


Do you know how small is our universe?



Light travels in exactly 299,792,458m/s . That's 29.9 million metres,approximately 300,000km per second! So imagine our latest radio detectors can detect up to 13.7 billion light years away. That is up to date,how good our technology is. And the ratio of the planets,everything is accurate. Actually,whether you want to believe it or not is okay. Have a look and hope you enjoy the video :)



-This film shows the known universe as mapped through astronomical observations. Every satellite, moon, planet, star, and galaxy is represented to scale and in its correct, measured location according to the best scientific research to date.
The data is maintained and curated by research by astrophysicists at the American museum of Natural History as the Digital Universe Atlas.


I believe,life form definitely exists in other parts of the Universe. Just that we do not know,and we don't have the technology to travel so far into the future. Yes,from this video,I marvel at the size of our universe. And I hate it because it makes me feel so inferior,insecure and insignificant. It makes me scared,what lies outside our 7 planets? If we are only a speck of light dot,what about the other specks of light dots that are next to us?

I feel extremely scared,insecure after watching this video :(
