Traveling forward in time is not a problem. You're doing that now. Can we travel backward in time? There is a theoretically possible way to do it using wormholes.



One solution to general relativity...

In a classical universe, if we knew all the positions and velocities for all particles, we could predict the future and the past. Quantum mechanics is not like this. It shows that reality is not deterministic but is...

Einstein Field equations explained intuitively and visually: Isaac Newton changed our paradigm by connecting earthly gravity, with the movement of heavenly bodies. He formulated an equation that is...

The gauge bosons of the standard model of particle physics are responsible for 3 of the 4 known forces in the universe. A force is conferred is through the exchange of virtual bosons. So for example in...

In a recent paper published by Applied Physics, authors Alexey Bobrick and Gianni Martire, outline how a physically feasible warp drive could in principle, work, without the need for negative energy. I spoke to them....

SUMMARY:

Why are we here? Why is there something instead of nothing. Part of the answer is rooted in physics. Matter is not the simplest thing there could have been. The simplest thing In physics is...

SUMMARY:

How is string theory related to quantum field theory? Quantum field theory (QFT) is a mathemat
ical
framework that is close to a theory of everything. It describes nearly all particles and forces...

If a tree falls in a forest and no one is around to hear it, does it make a sound? Philosopher George Berkeley asked this famous question in 1710, and people are still debating it.



Where is the forest...

Then Isaac Newton in 1687 showed that planets move due to the same forces we experience here on earth. If things could be explained with mathematics, to many people this called into question the need for a...

Quantum theory solved many problems with classical theory - the photoelectric effect solved by Einstein, atomic model solved by Niels Bohr. But quantum theory had a high price - determinism. it introduced...

In the Copenhagen interpretation, which is what is typically taught to undergraduate students, particles are in superposition. What is superposition? In quantum mechanics, there is no equation that states...

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...

Time travel is nothing special. You’re time traveling right now into the future. Relativity theory shows higher gravity and higher speed can slow time down enough to allow you to potentially travel far into the...

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...

We have 3D + 1D of time. Why aren’t there 4 dimensions or 2 dimensions? Can life exist in the 4th dimension? Is there something special about three dimensions that makes life possible? This is the question that But...

SUMMARY

Albert Einstein was ridiculed when he first published his theory. People thought it was too weird and radical to be real. Einstein wasn’t satisfied with his theory either, because the theory did not...

Does a final theory exist that can end our reductionist probing into ever shorter distances? Or is there no end to reductionism? There should be an end point because as the object of our measurement gets small...

A quantum wormhole was created by a team of physicists led by Maria Spiropulu of CalTech. But this was not a wormhole in spacetime, but a quantum holographic wormhole created inside a quantum computer.

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...

SUMMARY

What if time is not real, but an illusion? Isaac Newton believed time was absolute and ticked at the same rate for everyone, everywhere. But Albert Einstein shattered that view with the theory of relativity....

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...

Karl Schwarzschild crafted the first exact solution to Einstein's equations of general relativity. He found that as gravity increased around an object, there must be a point where even light could not escape. He theorized black holes.
