Universe and the Solar System
Objectives:
1. State the different hypotheses explaining the origin of the universe
2. Describe the different hypotheses explaining the origin of the Solar System.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

3. Science and religion have been rivals since
the dawn of time. Before the 20th century
there was no general consensus on
whether the universe had a beginning or
not.
4.
5.
6. RELATIVITY THEORY
In 1916 Albert Einstein
published the theory of
relativity which not only
gave him international
recognition but also proved
that the universe had a
beginning and was
continuously expanding.
7.
8. His equations could predict how fast
the galaxies were moving and
therefore proved that the universe
was continuously expanding.
However Einstein did not
like the idea that the
universe had a beginning and
therefore changed his
equation by adding a
“Cosmological constant” to
make his Theory Of
Relativity to support the
Steady State Theory that
the universe is eternal.
9.
10. oAccording to the theory, the
Big Bang occurred
approximately 13.798 ±
0.037 billion years ago.
oGeorges Lemaitre first
proposed what became the Big
Bang theory in what he called
his "hypothesis of the
primeval atom

13. ▪ The Steady State Theory is a theory and model alternative to
the Big Bang theory of the universe's origin .
▪ In steady state views, new matter is continuously created as the
universe expands, thus adhering to perfect cosmological principle.
▪ Sir James Jeans, in the 1920s, was the first to conjecture a steady
state cosmology.
▪ The idea was then revised in 1948 by Fred Hoyle, Thomas
Gold, Hermann Bondi and others.

Steady State Theory
17. In 1920 Belgian
cosmologist and Roman
Catholic Priest proved
that Einstein’s
“Cosmological Constant“
was a mistake
18. He predicted that if the Big Bang occurred it
would release “Cosmic Microwave Radiation”
that should still be in the universe today.
Cosmic Microwave Radiation is the oldest
electromagnetic radiation that the
hypothesized Big Bang produced in its early
moments.
19. However a lot of Astrophysicists were skeptical of the
proposal for the proposal due to two Reasons.
He lacked empirical evidence .
Astrophysicists felt like he had a
secret agenda that being a
catholic priest he wanted to push
The Big Bang Theory so it would
line up with the Biblical creation
account that God created universe
from a single point in time.
20.
21. ▪ Though Lemaitre faced a lot of opposition. In 1965
scientists discovered the “Cosmic Microwave
Radiation” that he had predicted. To this day the
“Cosmic Microwave Radiation” remains as the
strongest evidence to support The Big Bang
Theory.
▪ Whether it was for science or supporting his faith
he has still left a legacy as one of the founders of
The Big Bang Theory.
22. The theory of general
relativity predicts that a sufficiently
compact mass will usually deform
spacetime to form a black hole.
Around a black hole, there is a
mathematically defined surface
called an event horizon that marks
the point of no return.
The hole is called "black" because it
absorbs all the light that hits the
horizon, reflecting nothing, just like a
perfect black body in thermodynamics.
A Black Hole is a region of spacetime from which gravity prevents
anything, including light, from escaping.
23.
24. On 22 January Stephen Hawking wrote a
paper and everywhere there was news
There are no black holes.
Stephen Hawking changed his mind.
But all this is wrong because Hawking
never said it. But before we tell you what
he said lets talk about two theories.
25. Einstein's theory of
general relativity suggests
that the astronaut falling
into a black hole would
happily pass through the
event horizon, unaware of
his or her impending doom,
before being crushed at the
'singularity', the black
hole’s hypothetical infinitely
dense core.
Quantum theory dictates
that the event horizon must
actually be transformed
into a highly energetic
region, or 'firewall', that
would burn the astronaut to
a crisp even before he
reaches the singularity.
