How Everything in Physics Fits Together – Map

Unless you have an innate knowledge of physics, it’s pretty hard to figure out how all the concepts and theories fit together

Physics is a huge, complex field. It also happens to be one of the most fascinating, dealing with everything from black holes and wormholes to quantum teleportation and gravitational waves.

But unless you have an innate knowledge of the field, it’s pretty hard to figure out how all these concepts actually fit together.

After all, everyone is constantly trying to prove Einstein wrong, and Stephen Hawking famously struggled to come up with a ‘theory of everything’, so it’s easy to get confused about how things do actually fit together in physics (if at all).

YouTuber Dominic Walliman has created a map that shows how the many branches of physics link together, from the earliest days of classical physics and Isaac Newton, all the way through to Einstein’s relativity and quantum physics (with a little bit of philosophy thrown in there for good measure).

How to get to the sun?

The first space exploration to study a star up close

If all goes according to plan, starting around 3:30 am Eastern on Saturday, NASA will launch the Parker Probe from Cape Canaveral, Florida. If you’re game to stay up that late, check out the live stream of the launch below (or check back during daylight hours for a replay).

After launch, the probe will make its first pass of the sun in about three months. But it will actually take around seven years to dip down within 4 million miles of the solar surface and get a super-close look at the corona. (The corona extends outward about 5 million miles from the surface.) During those seven years, the Parker Probe will make use of Venus’s gravity to alter its orbit, gradually getting closer and closer to the sun.  Continue reading “How to get to the sun?”

Mars Terraforming Not Possible Using Present-Day Technology

There is not enough CO2 remaining on Mars to provide significant greenhouse warming were the gas to be put into the atmosphere

Mars does not retain enough carbon dioxide that could practically be put back into the atmosphere to warm Mars, according to a new NASA-sponsored study. Transforming the inhospitable Martian environment into a place astronauts could explore without life support is not possible without technology well beyond today’s capabilities. Continue reading “Mars Terraforming Not Possible Using Present-Day Technology”

A UFO Is Closing in on Earth and NASA Is Covering It Up, According to YouTubers

Open your eyes, sheeple.​

One of the nice things NASA does is stream live footage from the International Space Station as it orbits the Earth 16 times a day. It’s pretty calming stuff—until a UFO enters the picture. Then all bets are off.

On July 9, NASA was streaming footage from the ISS when YouTuber Streetcap1 spotted something (aliens? probably aliens) entering the Earth’s atmosphere. But as the object (again, almost 100 percent aliens) nears our planet, the NASA feed cut out. While Streetcap1 points out it could be a meteor, we’ve seen Independence Day. We know what’s up. You can see the video below:

That video was quickly picked up by dozens of other YouTube channels. Soon, extremely reputable sources of scientific journalism such as Express.co.uk were quickly on the case, with stories like SHOCK ALIEN CLAIM: ‘NASA cuts the ISS live feed moments after UFO appears.’

NASA has been accused of a ccover-up of the existence of aliens after its video live feed of the International Space Station (ISS) apparently went off just as a UFO appeared to be entering Earth’s atmosphere.

Curious as to why NASA would cover up such obvious evidence of an impending alien attack, the answers was:

“We have never seen UFOs in the popular sense,” said a NASA spokesperson, after a long, deep sigh. “The feed in question is the High Definition Earth Viewing experiment. Anytime the ISS has a signal, that feed is sending down video.”

But when the High Definition Earth Viewing system loses signal, the video stream goes dark. “The feed is not switched manually,” said the spokesperson. “It’s all done automatically. There’s nobody at a control board.
