“Try not to become a person of success, but rather try to become a person of value.” – Albert Einstein

Day 7, February 27th.

Today was tough. Woke up with a stomach ache, probably because of whatever I ate yesterday. I had to skip college as well as work because of it.

Then there were news that both India and Pakistan have shot down each other’s fighter jet, while an IAF pilot has been caught by the Pakistan army. As per the footage, they seem to be treating him with respect as per the Geneva convention. I pray for his safety and quick return.

Let us also pray that countries never go to war with each other.

Just to get some air I went out in the evening, tried to look for some birthday gift for myself but wasn’t able to decide on one. 😅

Then again, came back, had dinner, took medicine and went to bed.

So slow a day this has been.

Mass of the star via Einstein’s Theory

Albert Einstein published his theory of relativity in 1915 that the speed of light in a vacuum is unaffected by the motion of all observers and that the laws of physics are the same for all observers not moving or accelerating.

The theory allowed scientists and researchers to predict black holes, and even the behavior of planets in orbit. The theory explains that when we try to measure how fast something is moving, that speed can only be determined in relation to another object’s speed.

Einstein also predicted that the light from one star can be bent by the gravity from another star, and this will help us find the mass of the star with bent light. This theory was proved, after more than a hundred years with the help of Hubble Telescope. It is hard to find stars with the perfect alignment that can create an Einstein ring, a circle of light formed by one star passing in front of another star from our vantage point.

With the help of our Sun, scientists were able to measure White dwarf Stein 2051B mass as 68% of that of our Sun.

That is amazing. Going to such lengths for Einstein’s theory, these scientists and researchers do have a passion for Physics.
