This is avialable inside [R Analysis](https://github.com/MohamedElashri/Hubble/tree/main/R%20Analysis) Folder\n\nMy main implementation is in **python** and I relied about estimating Hubble constant first then relied on the fact the age of universe is reciprocal of Hubble constant.\n\nMain plot is \n\n![Hubble constant](https://github.com/MohamedElashri/Hubble/blob/main/Plots/Plot_2.png)\n\n\n**Hint**: Age of the universe is not 1/H_0 but there should be some correction factor that account for relative abundance of dark energy/(dark) matter/radiation and it is close of 1 which why we use this assumption. \n\n\nThe python implementation is available inside the Jupyter notebook [here](https://github.com/MohamedElashri/Hubble/blob/main/Age_of_the_Universie_.ipynb)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmohamedelashri%2Fhubble","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmohamedelashri%2Fhubble","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmohamedelashri%2Fhubble/lists"}
