Our Milky way galaxy is not stationary. It’s attracted by a massive object in space called the great attractor, at more than 600 km/s. What is this great attractor? Will it destroy us? And, what is Dark...

How will the universe end? Whether you think the universe is good, bad or indifferent, it will come to an end…someday. How will that happen? Will it simply die a slow death over time? Will it die dramatically in a big...

Is a theory of everything really possible? What makes us think it even exists? If we look at historical precedent, we can see that we have united seemingly completely unrelated forces and particles to a...

Dark energy is different than dark matter. They are both labeled dark because we don’t know what they are. Dark matter does not absorb, reflect or emit any light. It is inferred to exist only because of its...

Certain mathematical equations contain unnerving dangers, Arguably, E=mc^2 is the most famous equation in science. C is a very large number. But in Einstein’s, equation it is squared. This means that mass contains an insane...

SUMMARY:

Are black holes the source of dark energy? A new study by Farrah et al, published in February of 2023 claimed to have found a solution to dark energy, showing a connection with supermassive black ho

SUMMARY

The law of energy conservation may be the most fundamental law in physics. It says that overall energy is always conserved. It can never be created nor destroyed - it can only change form. But this law...

Alcubierre warp drive - faster than light travel? Is Warp speed possible? Enterprise from Star Trek can go 9000 times the speed of light. By comparison, the fastest manmade object, the Juno probe goes 0.0002 times...

SUMMARY

What if gravity repelled instead of attracted? Repulsive gravity may have shaped the entire history of our universe. For centuries gravity was defined by Isaac Newton’s Law of Universal Gravitation which...

Part 2 in our Multiverse series.

The universe is expanding, but why? Dark Energy might be the key in solving this mystery.

Dark Flow. We investigate why hundreds of galaxy clusters are rapidly drifting towards a specific point just outside the known universe.

Was the Universe Designed? Exploring the effect Dark Energy has on our Universe.

How can scientists possibly know the age of the universe? Well, through a variety of factors, including redshift, the CMBR and more.

A mysterious energy field present across the entire known Universe, which accounts for 70% of its mass-energy.

Nobel Laureate Antony Leggett describes his gut feeling that cosmology is ripe for a major revolution, and describes why he is not particularly sympathetic to the field of "quantum cosmology".

Cosmologist Rocky Kolb (Chicago) provides a brief background on the mystery of dark energy while explaining why the phenomenon is personally bothering him.

Cosmologist Justin Khoury, University of Pennsylvania, describes the enormous disparity between the observation and theoretical prediction of the vaccuum energy, commonly regarded as the worst failure of theoretical physics, and...

University of Chicago cosmologist Rocky Kolb relates how he reacts very differently to dark matter than dark energy: dark matter he regards as an opportunity, while dark energy "drives him nuts".

How did Hubble discover the expansion of the universe?

What happens when black holes collide? What is the speed of gravity? There are so many weird questions related to gravitational waves.
