Humans are naturally omnivores. We are capable of choosing a herbivorous diet though and that is what distinguishes us from other omnivorous species.

I have read somewhere where it was said that some of those galaxies could actually be smaller than they appear or be supermassive black holes. I watched a YouTube video where Michio Kaku was discussing the possibility of them.being supermassive black holes.

I just had a look at the Wikipedia article on Nemesis. It says that in 2017 that some scientist said that thought that the Sun may have had a companion star in the past, but it left the Solar System more than 4 billion years ago. This is a possibility. The reason why we would not be able to...

Yes, time dilation can be measured with current speed. However, humans can't travel into the future any more than a few milliseconds faster with current speeds. With current speeds the affects of time dilation are negligible.

Will humans ever be able to travel forward in time faster than the ordinary speed? According to relativity if someone were traveling at speeds close to the speed of light they would jump some years into the future. The question however is will this ever be possible? Can humans survive at such...

Does the Nemesis star really exist? I don't think it does. If the Sun had a companion star it should have been detected by now. Stars don't go hidden.

So sad. Rest in peace, Queen Elizabeth II. She was a monarch for over 70 years. King Charles III is now the monarch of the United Kingdom.

What would happen if they found a galaxy that dated to older than 13.8 billion years old? How would this affect cosmology?

They have been discussing installing locks on classroom doors that can be locked from the inside of the classroom in response to school shootings. Why are they discussing this instead of talking about banning guns? Wouldn't banning guns be easier?

A common misconception about evolution by those who object to it is what it refers to. It refers only to how life changes over time, not how life originated, not how the Earth originated, and not how the universe originated.

There are lots of laws in physics. Laws are less common in other fields of science. Theories don't upgrade to laws overtime. You will never see an article in a newspaper where a certain scientific theory has officially become a law. Gravity and evolution are both facts. They can both be...

Why do scientists refer to evolution as a theory which leads to the argument that evolution is "just a theory"? Why don't they use a less confusing word?

Will the universe keep expanding faster and faster for all eternity or is there a limit to how fast the expansion will get?

Colonizing white dwarf s.

Could something older than our universe originating from another universe get sucked into a wormhole and wind up in our universe therefore being older than our universe itself?
