The space pirates are baffled looking at the rate at which our universe is expanding. From 20 years, the scientists are trying to get to the core of understanding how the universe is able to expand at a faster pace than expected. The astronomer Edwin Hubble from the University of Chicago has named the precise rate of expansion as the “Hubble constant.”
Since then traditionally two methods were used but now the gravitational waves radiating from the neutron star collision has provided a new means to compute the Hubble constant. The neutron star collision helped make accurate calculations within 5−10 Years. As per the University of Chicago scientists, the Hubble constant provides an exact age and size of the universe which is like the Holy Grail from the time of the birth of cosmology. The use of gravitational waves brings out a totally new perspective on the universe, according to Daniel Holz from the university.
The galaxies further than the Milky Way seemed to be moving away from us as per the calculations. This discovery required a century of researching so as to understand the exact phenomena. The distance measuring is hard but conventionally the cosmic distance ladder technique that is the brightness of certain stars or supernovae were employed for answers. Thus, another way is to use the cosmic microwave background that is the pulse of light created at the time of making to assume and calculate the distance.
After the obtaining a huge mismatch in the calculation from the previous methods, lately, the LIGO detectors helped glimpse the light of the collision’s aftermath with a telescope, feel the gravitational waves, and also fabricate the distance. This is only going to get more interesting from here.
Now, even before venturing back to Mars, the space scientists want the astronomers to explore the Moon again using a new lunar lander developed by an aerospace giant “Lockheed Martin” to help the space flyers move from moon-orbiting space station to the cratered surface below.
